Product Description
LINK/2+ Integrated Connectivity Systems are the building blocks of high capacity wide area networks for voice-data-image communications. In private, public, and hybrid networking applications, LINK/2+ Systems form powerful digital networks characterized by bandwidth efficiency, integrated communications, and full network management capabilities.
In private networks, LINK/2+ Systems use an optimized protocol that integrates network traffic and provides an error protected channel for control and supervisory information. In hybrid networks, LINK/2+ Systems connect to public facilities at the DS-1 and higher levels. For DS-1 applications, LINK/2+ Systems use standard D4/G.732/TTC formatting to take advantage of the full voice and data services offered by common carriers. For applications using NTT High-Speed
Digital Leased Circuit Services, LINK/2+ Systems use JT-2 framing for trunk speeds up to 6.312
Mbps. LINK/2+ Systems also give users convenient access to fractional T-1 and switched 56 kbps services.
Networks of LINK/2+ Systems can accommodate up to 2000 nodes. This high number of nodes, full gateway capabilities, and intermachine link speeds ranging from 4.8 kbps to 2.048 Mbps give LINK/2+ networks outstanding flexibility to connect multiple sites with widely varying requirements throughout the world.
The design of LINK/2+ Systems ensures minimal interruption of critical communication facilities. Redundant system control elements are available on all LINK/2+ models. After a communication facility failure, automatic alternate routing reconnects critical circuits according to programmable priorities. System options enable backup or expansion of circuit bandwidth using dial-up networks. These capabilities allow network design to be based on average rather than peak loads.
Optional microcontroller-based digital phase locked loop (PLL) circuitry on LINK/2+ Systems, with on-board Stratum 3 accurate oscillator and clock qualifier monitor circuit, ensures detection of faulty clock reference as well as smooth network operation during subsequent clock switchover. The PLL option enhances network reliability and offers greater operational flexibility.
The LINK/2+ System incorporates a modular design for flexibility and superior performance. See the "Functional Description" paragraphs for a description of each module.
APPLICATIONS
LINK/2+ Systems form the basis for powerful and efficient private and hybrid networks and also give common carriers an economical means of providing channelized services with high reliability, supported by comprehensive diagnostics. Figure 1-1 indicates the range of voice-dataimage inputs to a LINK/2+ System along with different types of network connections. A
LINK/2+ network can integrate a wide variety of inputs into a cost-effective and efficient solution to a full range of communications problems.

PRODUCT FEATURES
LINK/2+ Systems deliver full integration of voice, data, and image transmission over T-1/E-1 facilities (1.544 to 2.048 Mbps), NTT High-Speed Digital Leased Circuit Services (6.312 Mbps), and lower speed facilities as well (from 4.8 kbps). Fractional T-1/E-1/NTT services are also supported. LINK/2+ Systems offer automatic alternate routing and other management capabilities for full and fractional connections through an embedded ARQ control channel. In addition, asymmetrical and simplex transmission facilities are supported for those applications where transmit and receive speeds differ for individual channels.
LINK/2+ System features include:
●
Node capacity to as many as 2000 nodes
●
Advanced Bandwidth Management (ABM) for network efficiency
●
Extensive system security
●
Redundant operation to ensure high reliability
Node Capacity
LINK/2+ networks can directly address up to 2000 nodes. The TIME/VIEW 2000 Network
Management System establishes all routing tables and channel connections. Supervisory port commands are also available for establishing internetwork connections.

Advanced Bandwidth Management (ABM)
The LINK/2+ System provides the following ABM features:
●
Selective routing
●
Grooming
●
Bumping
●
ILP bandwidth contention and pooling
Selective Routing
Selective routing is the process by which routing decisions are made according to the specific path criteria defined in a channel’s ABM profile. This feature is supported for channels that pass through transfer nodes. At connection time, the Network Module will test a possible outbound intermachine link to determine if it meets a channel’s ABM profile requirements. Any intermachine link failing to meet these requirements is rejected and the next link in the routing table will be considered. This process continues until a suitable intermachine link is found and the connection is made, or until all possible outbound links have been rejected and an appropriate disconnect reason is assigned. The user has the ability to override selective routing path criteria.
For information on defining a channel’s ABM profile, see Advanced Bandwidth Management
Profile Parameters chapter in the LINK/2+ Configuration Planning Manual. For information on routing, see Routing chapter in the LINK/2+ Configuration Planning Manual.
Grooming
Grooming is the process of disconnecting and reconnecting channels at a time of minimal usage with the intention of obtaining a more desirable route. The system maintains two user-specified timetables that represent the grooming disconnect time and grooming reconnect time for each day of the week. These timetables are checked against the actual time at least once every 60 seconds.
Provided that the system grooming parameter is enabled and the grooming disconnect time has been reached, the system searches for the first channel with grooming enabled in its ABM profile which meets certain qualifications. Any channel that does not have grooming enabled in its
ABM profile or does not meet the required conditions remains connected. Any channel(s) disconnected for grooming will be reconnected when the grooming reconnect time has been reached.
Dial-up services backup intermachine links will be disconnected at grooming disconnect time if and only if the primary intermachine link has been restored to in-service status. Once disconnected, dial-up services backup intermachine links are not reconnected at grooming reconnect time. Another feature, automatic grooming, provides grooming of switched backup bindles every 10 minutes. This feature will disconnect the backup bundle when the primary bundle is stable for 10 minutes and no connections are present on the backup bundle.
Grooming of channels that pass through transfer nodes is supported with certain restrictions listed in the System Parameters chapter in the LINK/2+ Configuration Planning Manual.

For information on enabling grooming in a channel’s ABM profile, see Advanced Bandwidth
Management Profile Parameters chapter in the LINK/2+ Configuration Planning Manual. For information on system grooming and specifying grooming disconnect and reconnect times, see
System Parameters chapter in the LINK/2+ Configuration Planning Manual.
Bumping
Bumping is the process that will selectively disconnect (bump) one or more lower level channels, thereby allowing a higher level channel to connect. The higher level channel connects using the resources previously allocated to the lower level channel(s). A channel is assigned this bumping level in its ABM profile.
The bumping process utilizes two schemes: end-to-end and point-to-point. The end-to-end scheme attempts to locate a single channel that, when bumped, will provide enough bandwidth for the bumper to reach its destination node. The point-to-point scheme searches for one or more channels that, when bumped as a group, will satisfy the bumper’s bandwidth requirements to the next node.
For information on assigning bumping levels, see Advanced Bandwidth Management Profile
Parameters chapter in the LINK/2+ Configuration Planning Manual. To enable system bumping and select the bumping scheme, see System Parameters chapter in the LINK/2+ Configuration
Planning Manual.
ILP Bandwidth Contention and Pooling
The ILP bandwidth contention feature enables the user to designate ILP DS-0 channels as bandwidth contention channels.
For information on designating ILP bandwidth contention channels, see Digital Voice and
Channelized Services Parameters chapter in the LINK/2+ Configuration Planning Manual. For information on enabling ILP bandwidth contention and bandwidth pooling on a system level, see
System Parameters chapter in the LINK/2+ Configuration Planning Manual.
System Security Features
The LINK/2+ System provides the following features for security:
●
Password protection
●
Gateway and nongateway designation
●
Nodal security
●
Intermachine link security

Password Protection
Password protection ensures that unauthorized users do not have access to the LINK/2+ System via the supervisory terminal. Two levels of password protection correspond to the gateway and nongateway commands discussed in the following paragraphs. If the supervisory port is designated as a gateway, users with password 2 can enter gateway and nongateway commands, while users with password 1 can enter nongateway commands only.
For information on defining passwords, see Chapter 4, Support Commands.
Gateway and Nongateway Designation
The gateway status of the supervisory port determines the types of commands that can be issued from the node. Gateway status also affects the supervisory computer port, for example, when an element management system is used. Designating the supervisory port or supervisory computer port as a gateway enables a device connected to the port to issue gateway commands to the local node and to remote nodes.
Gateway commands affect node operation, for example, configuration and diagnostic commands. Gateway commands are divided into two groups:
●
Global gateway commands are accepted by the local node and all remote nodes within the same network if the supervisory port or supervisory computer port originating the commands is designated a gateway. Global gateway commands are typically used for diagnostics.
Global gateway commands are noted by a G in the "G" column of the command summary tables throughout this manual.
●
Nonglobal gateway commands are accepted by a local node if the supervisory port or supervisory computer port is designated a gateway.
Nonglobal gateway commands are accepted by a remote node in the same network if:
The supervisory port or supervisory computer port originating the command is designated a gateway.
The node number of the node originating the command is on the alarm notification list of the node receiving the command.
Nonglobal gateway commands are typically used for configuration activities. Nonglobal gateway commands are noted by a G in the "G" column of the command summary tables throughout this manual.
Commands that do not affect node operation, for example, display commands, are called
nongateway commands. These commands may be directed to a local or remote node regardless of the gateway/nongateway status of the supervisory port or the supervisory computer port.
Nongateway commands do not have an entry in the "G" column of the command summary tables throughout this manual.
NOTE:
Supervisory port and supervisory computer port gateway status cannot be selected via the local supervisory terminal. Gateway status is initially determined by Network Module DIP switch but can be changed by a SET GWY or CLR GWY command issued from a remote node. See Chapter 6, Configuration Commands.

Nodal Security
Nodal security restricts a LINK/2+ System from accepting global gateway commands. When nodal security is enabled, all global gateway commands are interpreted by the LINK/2+ System as nonglobal gateway commands and are accepted only if both:
●
The supervisory port or supervisory computer port originating the command is designated a gateway.
●
The node number of the node originating the command is on the alarm notification list of the node receiving the command.
For information on setting and clearing nodal security, see Chapter 6, Configuration Commands.
Intermachine Link Security
Intermachine link security determines whether supervisory port or supervisory computer port commands issued from remote nodes will be accepted over a specified intermachine link.
Enabling intermachine link security does not affect voice or data communications between nodes.
For more information on operation when intermachine link security is enabled, see Intermachine
Link Parameters chapter in the LINK/2+ Configuration Planning Manual.
Redundant Operation
All LINK/2+ modules except I/O channel modules are capable of redundant operation. The following paragraphs describe the types of redundancy available for different modules.
The Network Module, Interlink Module, Voice Processor, Channelized Services Processor,
Integrated Trunk Module, D-Channel Module, and Bypass Module can be configured for redundant operation. When redundancy is toggled, all channels supported by that module are first automatically disconnected and then automatically reconnected.
Redundant operation for the Voice Server Module is achieved with pooled redundancy, that is, connections on a failed Voice Server Module disconnect and reconnect using unassigned channels on another Voice Server Module.
For the X.50 Server Module, up to four primary and four redundant modules may be installed at a node. Modules are defined as either primary or redundant via a user entered command. An algorithm assigns a redundant X.50 Server Module to automatically take over for a failed primary X.50 Server Module. During redundancy switchover, the X.50 DS-0 channels and X.50
subrate channels remain fully connected.
When a redundant Power Supply Module is installed, both Power Supply Modules for that
Mainframe share the load under normal operation. If either Power Supply Module fails, the remaining Power Supply Module assumes the full load for that Mainframe without traffic interruption.
1-6
L2UG
6/30/94
Redundant operation of any of these modules occurs automatically when a failure is detected in the primary module. Redundant operation may also be activated via operator initiated command except for the Voice Server Module.
The Integrated Trunk and D-Channel Modules implement a form of redundancy called cold standby. When a primary Integrated Trunk Module or D-Channel Module fails, the redundant module comes online automatically. Integrated Trunk Module proprietary bundles are dropped and reconnected automatically.
Redundant Digital Termination Modules or Link Framing Modules can be used with redundant
Interlink Modules, Voice Processors, Integrated Trunk Modules, and Channelized Services
Processors. If either of the primary modules fails, the redundant pair of modules assumes operation. Some Digital Termination Module and Link Framing Module models have two independent units on a single module, allowing vertical redundancy. See the Modules section of the LINK/2+ Installation and Maintenance Manual for further information on redundancy capabilities of these modules.
FUNCTIONAL DESCRIPTION
The following paragraphs describe the function of all units and modules comprising a LINK/2+
System. A functional block diagram of a typical LINK/2+ System is shown in Figure 1-2.
Mainframe
The Mainframe provides mounting and connectors for all modules. Mainframes are available with 6 slots (microLINK/2+), 13 slots (miniLINK/2+), or 18 slots. As shown in Figure 1-4, 18slot Mainframe systems can include a Control Mainframe and one or two Expander Mainframes.
See the LINK/2+ Configuration Planning Manual for information on the number and types of modules that can be installed in each Mainframe.
The Line Termination System (LTS) Chassis is a special type of Mainframe designed to accommodate up to 12 Line Termination Modules. An LTS Chassis is required when Subrate
Channel Processors are installed in the LINK/2+ Mainframe (see "Data I/O Channel Modules" paragraph for a description of the Subrate Channel Processor). The LTS Chassis can be collocated with the LINK/2+ Mainframe or installed in a separate rack within cabling distance
(approximately 50 feet) of the LINK/2+ Mainframe.
Fan Housing
The Fan Housing provides cooling for the 13-slot and 18-slot Mainframes. The 6-slot Mainframe has a Fan Tray Module which is integral to the Mainframe.

Power Supply Chassis and Power Supply Module
The Power Supply Chassis provides mounting for Power Supply Module(s) for 18-slot
Mainframes. Power Supply Modules for 6-slot and 13-slot Mainframes are integral to the
Mainframe.
The Power Supply Module converts AC power into regulated +5 VDC and
±
12 VDC required for operating a Mainframe. The Power Supply Module is the switching regulator type and incorporates control and logic circuits that provide for load sharing when a redundant Power
Supply Module is installed (13-slot and 18-slot Mainframes only). If a Power Supply Module failure is detected, control is transferred to the redundant Power Supply Module without interruption of power to that Mainframe.
Network Module
The Network Module exercises primary microprocessor control over the LINK/2+ System. The
Network Module processes commands from the supervisory terminal or supervisory computer, and provides the system clocks via phase locked loop.
●
The Network Module supervisory port permits an attached asynchronous ASCII terminal or microcomputer to communicate with the Network Module microprocessor. The supervisory
computer port permits the TIME/VIEW Network Management System (NMS) to communicate with the Network Module microprocessor. A supervisory terminal or network management system can access stored information to:
Define or display programming parameters
Display network configuration and connect status
Connect or disconnect channels
Define channel, bundle, and intermachine link routing
Initiate diagnostic tests and display test results
A microcomputer attached to the supervisory port can be used to download operational software to the Network Module, Interlink Module, Integrated Trunk Module, VSM.3 and
VSM.5 Voice Server Modules, and X.50 Server Module.
●
The Network Module external port can be used to connect to a LINK Channel Service Unit
(LINK/CSU). The LINK/CSU is an intelligent channel service and digital service unit combination that is programmable for either extended superframe (ESF) or D4 framing format. The LINK/CSU frees up slots in the LINK/2+ System Mainframe and provides up to
28 nonredundant or 14 redundant CSUs.
A LINK/2+ supervisory terminal or network management system can issue commands to the
LINK/CSUs in the network. For information on the LINK/CSU, see the LINK/CSU User’s
Guide.
L2UG
6/30/97
1-9
●
The Network Module station clock port allows one or two external clock sources (station clocks) to be connected to the Network Module. The LINK/2+ System can be programmed to use these station clocks to provide system clocking. Station clock speeds between 2400 bps and 2.048 Mbps are supported.
Driver Module
Driver Modules provide the interface between the 18-slot Control Mainframe and Expander
Mainframe(s). When Expander Mainframes are used, a Driver Module must be installed in the
Control Mainframe and in each Expander Mainframe.
Interlink Module
The Interlink Module provides the interface between the common bus and an intermachine link.
The Interlink Module assembles the data frame, maintains intermachine link synchronization, and transfers data between the I/O channels and that intermachine link.
Interlink Modules are available that can be configured for:
●
Symmetrical operation in which the transmit and receive speeds are the same
●
Asymmetrical operation in which the transmit and receive speeds are different
●
Simplex operation in which data is either transmitted or received but not both
A Satellite Buffer option for the Interlink Module provides additional buffer capability which compensates for variable delay times commonly associated with satellite transmissions.
Digital Termination Module
The Digital Termination Module interfaces with unframed North American T-1 or European megabit service. The module is available in both single and dual unit configurations. The Digital
Termination Module interfaces directly with a CSU. For digital radio facilities, the Digital
Termination Module interfaces directly with the DSX-1 interface of the transceiver.
Link Framing Module
The Link Framing Module (models LFM and LFM.1) interfaces with unframed or framed T-1 service. The LFM and LFM.1 Modules support D4 framing requirements of AT&T PUB 62411.
The LFM Module supports ESF format as defined in Government of Canada Department of
Communications specification CS-03.
An Equalizer Linedriver Module can be used with an LFM Module to meet Government of
Canada Department of Communications specification CS-03 Issue 6 Supplement B Amendment
3 for connection to common carrier at distances up to 655 feet (200 meters).
The LFM.3 Link Framing Module interfaces with 2.048 Mbps digital services that conform to
CCITT recommendation G.704.
1-10
L2UG
6/30/94
The LFM.5 and LFM.6 Link Framing Modules interface with the Nippon Telephone and
Telegraph (NTT) Branching T-1 service. For further information on these modules, see the Link
Framing Module Model LFM.5 and Link Framing Module Model LFM.6 User’s Manuals.
The LFM.9 Link Framing Module provides independent station clock at 1.544 MHz to major nodal hubs in a network. The LFM.9 provides clock from one of two inputs to up to eight nodes.
The module can switch between inputs without causing a clock fallback at the Network Module if one input fails.
The LFM.10, LFM.11, and LFM.12 Link Framing Modules provide n x 64 kbps or n x 56 kbps bundled output over T-1 facilities to enable low-cost access to fractional T-1 service. These modules create user-selected bundle sizes from 1 to 24 DS-0 channels at speeds from 56 kbps to
1.544 Mbps. Release 7 and later Link Framing Modules (LFM.10, LFM.11, and LFM.12) are software programmable. Pre-release 7 modules use DIP switches to set link framing parameters.
For pre-release 7 modules, see the Link Framing Module Models LFM.10, LFM.11, and LFM.12
User’s Manual for DIP switch settings.
The LFM.14 Link Framing Module combines four T-1 links together and provides the framing and electrical encoding for interfacing to the Japanese NTT High-Speed Secondary Service. This service allows a single 6.312 Mbps trunk to be divided into multiple n x 64 kbps bundles, where n ranges from 1 to 24.
Bipolar Interface Module
The Bipolar Interface Modules (BIM.1, BIM.2, and BIM.3) interface a Voice Processor,
Channelized Services Processor, or Integrated Trunk Module to a DSX-1 or G.703 transmission facility. The Bipolar Interface Module converts the unipolar non-return-to-zero (NRZ) signal from the Voice Processor, Channelized Services Processor, or Integrated Trunk Module to alternate mark inversion (AMI) bipolar format.
The Bipolar Interface Module (64 kbps BIM) interfaces the ILC.2 Interlink Module, QSC.2 Quad
Synchronous Module, or QSP.2 Quad Synchronous Processor Module to a G.703 transmission facility. The 64 kbps BIM supports G.703 64 kbps codirectional and contradirectional coding.
Integrated Trunk Module
The Integrated Trunk Module allows hybrid networking in a LINK/2+ network using industrystandard channelized services. Using the Integrated Trunk Module, networks can take advantage of public network services while maintaining cost effectiveness and network management control.
The Integrated Trunk Module uses a flexible, multipurpose channelization format in which varying numbers of DS-0s are grouped into proprietary and nonproprietary bundles. The
Integrated Trunk Module can support up to 24 proprietary bundles per physical link, 24 DS-0 nonproprietary bundles per T-1 link, or 31 DS-0 nonproprietary bundles per E-1 link. The
Integrated Trunk Module supports Switched 56K service, ISDN primary rate, and byte alignment.

Module.
The D-Channel Module supports multiple Q.931 protocols, including 4ESS, 5ESS, NTT,
NUMERIS, DMS250/100, and Austel. The D-Channel Module supports carriers in different countries including AT&T in the United States, NTT in Japan, AOTC in Australia, and France
Telecom.
Voice Processor
The Digital Voice Processor Module (Voice Processor) transfers DS-0 channels via time slot interchange between other LINK/2+ System modules and a DS-1 trunk. DS-0 channels can be locally or remotely connected to other DS-0 channels, Quad Voice Module channels, Enhanced
Voice Module channels, Quad Synchronous Module channels, or Quad Synchronous Processor channels. A Voice Processor with ADPCM capability can convert PCM channels to ADPCM channels on a per channel basis to provide more efficient bandwidth utilization. Voice Processor channels can be processed by a Voice Server Module to achieve greater voice compression and echo cancellation. The Voice Processor can connect to a Digital Termination Module, Link
Framing Module, or LINK/CSU.
The ILP.8 and ILP.13 Voice Processors provide access to Japanese TTC (Telecommunications
Technology Committee) formatted PBXs.
A Facility Interface Module (FIM.1) is used with an ILP.8 or ILP.13 Voice Processor to provide electrical translation and isolation between the Voice Processor and the 2.048 Mbps TTC trunk.

Data I/O Channel Modules
The following data I/O channel modules can be used in a LINK/2+ System:
●
The Quad Synchronous and Dual Synchronous Modules provide the interface between I/O data channels and the common bus. Each Quad Synchronous Module contains four individual synchronous I/O data channels. Each Dual Synchronous Module contains two high speed synchronous I/O data channels. The Quad Synchronous and Dual Synchronous Modules have the ability to supply n x 64 kbps rates to be formatted in bundles by the Channelized Services
Processor and placed on a DS-1/E-1 trunk. The Quad Synchronous Module can supply n x 56 kbps or n x 64 kbps rates for placement on a T-1 or E-1 interface by the Integrated Trunk
Module.
The QSC.7 Quad Synchronous Module has a single application of converting 56 kbps subrate data channels into 64 kbps logical DS-0 channels.
●
The Quad Synchronous Processor provides the interface between I/O data channels and the common bus. Each Quad Synchronous Processor contains four individual synchronous I/O data channels supporting the range of data rates from 50 bps to 1.984 Mbps. All ports can operate simultaneously at 1.984 Mbps. The Quad Synchronous Processor has the ability to supply n x 64 kbps rates to be formatted in bundles by the Channelized Services Processor and placed on a DS-1/E-1 trunk. The Quad Synchronous Processor has the ability to supply n x 56 kbps or n x 64 kbps rates to be formatted in bundles by the Integrated Trunk Module and placed on a DS-1/E-1 trunk. The Quad Synchronous Processor can be configured for symmetrical, asymmetrical, or simplex operation.
Individual channels on a Quad Synchronous Processor can be configured to operate in the following special modes:
Broadcast/polling mode—In broadcast/polling mode, a single channel at a central host site can connect to multiple remote channels called a nest poll group. The channels forming the nest poll group must reside in the same nest (LINK/2+ Mainframe). The communication between the host channel and the remote nest poll group uses only one time slot in the connecting intermachine link. When the host channel transmits, all nest poll group channels receive the transmission. Only one nest poll group channel can transmit at a time.
56K/64K mode—Switched 56K service provides 56 kbps of data communication on a dial-up basis. In switched 56K and nonswitched 56K modes, data is always transmitted at
56 kbps. In switched 56K mode, the Quad Synchronous Processor performs speed translation from 56 kbps to 64 kbps (DS-0) format by "stuffing" the eighth bit with signaling and dialing information received from a Terminal Interface Unit (TIU). In nonswitched 56K mode, the eighth bit is stuffed with a 1. A Quad Synchronous Processor operating in switched 56K mode can be scanned by an Interlink Module (for networking to a remote node) or by a Voice Processor, Integrated Trunk Module, or Channelized
Services Processor.
LPDA-1 mode—LPDA-1 (Link Problem Diagnostic Aid) is an IBM test protocol that allows a front end processor (FEP) to obtain test information from a pair of remote modems. In LPDA-1 mode, the Quad Synchronous Processor channel allows function transmission in inband mode which guarantees compliance with ones density. Any transition of the function lead (F3 IN) will be communicated from the FEP to the modem
1-16
L2UG
6/30/94
to start test mode, even if the Quad Synchronous Processor channel is in data mode. Test mode continues until another transition of the F3 IN function is sent by the FEP.
Simplex broadcast mode—In simplex broadcast mode, a single originator channel at one node can connect to multiple terminator channels at other nodes. When the originator channel transmits, all terminator channels receive the transmission, but the terminator channels cannot transmit back to the originator.
●
The Quad Asynchronous Module provides the interface between I/O data channels and the common bus. Each Quad Asynchronous Module contains four individual asynchronous I/O data channels.
●
The Dual Isochronous Module provides the interface between I/O data channels and the common bus. Each Dual Isochronous Module contains two I/O data channels that can be independently configured for isochronous, plesiochronous, or asynchronous operation.
●
The Isochronous Communication Module provides the interface between I/O data channels and the common bus. Each Isochronous Communication Module contains two I/O data channels that can be independently configured for isochronous or plesiochronous operation.
The Isochronous Communication Module provides frequency discrimination, I/O rates up to
1.544 Mbps, plus more speeds than available on the Dual Isochronous Module.
●
The Subrate Channel Processor is intended for generation of 64 kbps DS-0 channels from customer subrate data and 56 kbps data in a DDS environment. The Subrate Channel
Processor can support DS-0A or DS-0B signal formats and any mix of primary/secondary channel capability.
In DS-0A configuration, the Subrate Channel Processor emulates the Office Channel Unit
(OCU) functionality. Four independent ports at the standard subrates (2.4, 4.8, or 9.6
kbps), secondary port rates (3.2, 6.4, or 12.8 kbps), and 56/72 kbps are supported, depending on the model. On a per port basis, a 64 kbps DS-0 channel is generated. The overall throughput is 256 kbps (four DS-0 channels). Data to and from the network is carried over four independent DS-0A formatted channels through an Interlink Module or
Voice Processor.
In DS-0B configuration, the Subrate Channel Processor integrates the functionality of the
OCU and Subrate Data Multiplexers (SRDM). Up to five standard subrates or secondary port rates are multiplexed into a single 64 kbps channel. Data to and from the network is carried over a single DS-0B formatted channel through an Interlink Module, Integrated
Trunk Module, or Voice Processor.
A Line Termination Module is required to terminate the Subrate Channel Processor connection. Each Line Termination Module supports up to two Subrate Channel Processors.
Line Termination Modules are installed in a separate LTS Chassis (see "Mainframe" paragraph).

●
If any error messages appear or alarm indicators light, see the Troubleshooting chapter in the
LINK/2+ Installation and Maintenance Manual.
Bit Error Rate (BER) Test
Upon start-up, each Interlink Module and proprietary bundle on an Integrated Trunk Module continuously performs a BER test to determine the quality of the transmission facility. The BER results are averaged over several half-minute periods (windows) and then categorized based on the values presented in Table 2-1. BER status can be displayed with the DSP ST DL command; see Chapter 5, Display Commands. BER is not calculated on a simplex transmit only intermachine link.
The BER affects connections in the following manner:
●
Connections are disallowed if the BER fails to exceed POOR at least once following powerup or reset.
●
If an ABM profile is used, channels can be automatically connected or rerouted only over intermachine links meeting the user-specified link error performance level.

Channel Connections
The LINK/2+ System automatically connects noncontention channels after start-up. For I/O channels designated as contention channels, the LINK/2+ System allocates bandwidth dynamically, at the request of the user (via I/O module control signals). A bandwidth contention channel will be automatically connected if the following conditions exist:
●
The request function (I/O module control signal) for that channel is activated.
●
Sufficient bandwidth is available.
Channel connect messages for noncontention channels are displayed on the supervisory terminal; see "Alarm Indicators and Messages" paragraph.
When the network is configured, individual channels or groups of channels can be designated as noncontention channels or as bandwidth contention channels, according to the application. For example, the noncontention channels may use all of the bandwidth during daytime operations.
The contention channels can come online when bandwidth becomes available due to some noncontention channels being programmed to be disconnected at a specific time in the evening.
For information on configuring channels as contention or noncontention, see the LINK/2+
Configuration Planning Manual.
When used with the Integrated Trunk Module, the D-Channel Module can provide dial-up connections between nodes, as well as bandwidth expansion and backup or redundancy of existing intermachine links.
For commands used to connect and disconnect channels, see Chapter 6, Configuration
Commands.
Alarm Indicators and Messages
To inform the user of a problem or status:
●
Module alarm indicators light.
2-6
L2UG
6/30/94
●
Unsolicited alarm messages are displayed on the supervisory terminal when system errors occur, when define (DEF) or SET commands are issued, and at a fixed time interval until the alarm is cleared. Other alarm conditions must be solicited by entering the DSP AQ command.
●
Unsolicited channel connected and not connected messages are also displayed on the supervisory terminal.
NOTE:
The supervisory terminal will NOT display unsolicited messages if the SET MUM LOC command has been entered. To resume the display of unsolicited messages, enter the CLR MUM LOC command.
See Chapter 4, Support Commands.
The supervisory terminal will NOT display continuous occurrences of alarm 07 (intermachine link declared out-of-service) if the DEF DL parameter alarm 7 masking (AL7MASK) is set to ON. See
Intermachine Link Parameters chapter in the LINK/2+ Configuration
Planning Manual.
Alarm 04 (power supply failure) does not occur in the microLINK/2+
System, and alarm 08 (fan failure) does not indicate a fan failure in the microLINK/2+ System. The Fan Fail Alarm Defeat Plug (FFD) must be installed to avoid continuous display of alarm 08. If the
Power Supply Module fails or the fans stop rotating, see the
LINK/2+ Installation and Maintenance Manual for replacement procedure.
If an alarm condition occurs, see the Troubleshooting chapter in the LINK/2+ Installation and
Maintenance Manual. For a summary of error and status messages, see Appendix A.
ACCESSING THE SUPERVISORY PORT
If a local supervisory terminal is to be used, the LINK/2+ System must be programmed by
Network Module DIP switch to use default supervisory port parameter values or parameter values stored in the database:
●
If Network Module DIP switch is set to use default supervisory port parameter values, the parameter values take effect when power is applied to the LINK/2+ System. Default supervisory port parameter values are:
speed: 9600 bps
stop bits: 1
data bits/parity: 8 data bits, no parity
●
If Network Module DIP switch is set to use parameters from the database, supervisory port parameter values must be defined from a supervisory port or a supervisory computer port.
See "Define Supervisory Port Parameters (DEF SP) Command" paragraph in Chapter 6,
Configuration Commands.
L2UG
6/30/94
2-7
The supervisory port is online when the LINK/2+ System is turned on. To access the supervisory port:
●
Ensure that:
Supervisory terminal is connected to LINK/2+ System.
Supervisory port parameter values have been defined.
Supervisory terminal is turned on and operational.
●
If passwords have been defined, log in per "Supervisory Port Log In" paragraph.
●
Prompt (Nxxxx>) must be displayed before commands can be entered. If prompt is not displayed, enter Control C character or BREAK.
To prevent unauthorized supervisory port access, log out per "Supervisory Port Log Out" paragraph when you are finished at the supervisory terminal.
Supervisory Port Log In
If passwords have been defined, the password prompt (ENTER PASSWORD:) appears on the supervisory terminal whenever power is applied or a reset occurs to the LINK/2+ System. To log in to the LINK/2+ System, carefully key in the correct password, then press RETURN key.
If the password is entered correctly:
●
Time and date appear on the supervisory terminal.
●
Prompt (Nxxxx>) appears.
NOTE:
If the password is not entered correctly, the password prompt
(ENTER PASSWORD:) appears again on the supervisory terminal.
If the password is entered incorrectly three times, the LINK/2+
System will wait 30 seconds before allowing further password attempts. See your system manager for correct password.
If necessary, passwords can be disabled. See the Network Module chapter in the LINK/2+ Installation and Maintenance Manual.
The password used to log in determines the commands that you are allowed to use. See "System
Security Features" paragraphs.
Supervisory Port Log Out
To prevent unauthorized system access, you can log out of the LINK/2+ System in two ways:
●
By entering the EX command. At the prompt (Nxxxx>), type EX to log out. If prompt is not displayed, enter Control C character or BREAK.
2-8
L2UG
6/30/94
●
By a time out. If the log in time out parameter is enabled, you will be logged out if no keystroke is entered for 30 minutes.
After logging out of the LINK/2+ System:
●
Message "Logged Out" appears on the supervisory terminal.
●
Time and date appear.
●
Password prompt "ENTER PASSWORD:" appears.
NETWORK MODULE/INTERLINK MODULE OPERATIONAL SOFTWARE
The LINK/2+ System is shipped with the Network Module/Interlink Module operational software already installed in the Network Module(s). Two copies of the software reside on each
Network Module; a copy in each of two flash memory banks. In addition, a high density, 3.5inch floppy disk containing the operational software is also provided.
NOTE:
The Interlink Module software is resident on the Network Module and is automatically loaded to the Interlink Modules by the Network
Module. No separate action by the user is required.
If a new version of the software is released, perform the following procedure to load the operational software, provided on the floppy disk, from a microcomputer to the Network
Module.
Procedure 2-3. Loading Network Module/Interlink Module Operational
Software
1.
Determine the supervisory port parameters for use in configuring the microcomputer by entering the DSP SP command. Record these parameters:
•
SPEED: for example, 9600 bps
•
STOP: 1 stop bit (required setting)
•
DATA: 8 data bits, no parity (required setting)
If the STOP and DATA parameters do not match the required settings, enter the DEF SP command to change the supervisory port parameters to the required settings.
2.
Connect the serial port of the microcomputer to the supervisory port of the LINK/2+
System. The microcomputer should have the following:
•

3.
Using the parameters recorded in step 1 for the supervisory port, configure the microcomputer communications application software for the same parameters.
4.
Verify that the communications application is running correctly by entering a supervisory port command such as DSP TIM.
5.
Verify (on the disk label) that the version of the operational software is correct prior to loading and record the filename.
6.
Insert the operational software disk into the microcomputer.
7.
Replace the operational software in the offline bank of flash EPROM with the new operational software by entering:
LOA SW n:ss (or LOA SW n:ss/F)
NOTE:
If the terminal emulation program running on the microcomputer supports a speed of 57600 bps, you can use the optional /F modifier with the LOA SW command to download the operational software at a speed of 57600 bps to the Network Module.
You do not need to reconfigure the SP port speed to 57600 bps when using the /F modifier as the Network Module automatically switches the SP port to this speed. However, you do need to reconfigure the emulation program speed to 57600 bps.
The following message is displayed:
ERASING OFFLINE-FLASH
NOTE:
To abort the LOA SW command, enter CONTROL C. If the file transfer has been started, press ESC to abort the file transfer.
When erasing is complete, the following message is displayed:
CONNECT SP PORT TO PC AND INVOKE XMODEM PROTOCOL.
C’s appear on the screen until the file transfer is started.
8.
Set the file transfer protocol on the microcomputer to XMODEM to send the file from the microcomputer to the LINK/2+ System. Enter the path and filename recorded from the disk label.
If successful, the load process takes about 12 minutes (at 9600 bps). If not successful, repeat step 7.
PRECAUTION: The TGL BNK command is used to upgrade the system.
Issuing this command to an online Network Module will automatically reset the node.
9.
When ready to upgrade, enter:

General Information
The supervisory port allows network control, monitoring, diagnostics, information retrieval, and configuration activities for the LINK/2+ System to be conducted from a supervisory terminal.
Supervisory port commands can be directed to the local LINK/2+ System and to remote
LINK/2+ and LINK/1 Systems in the network. Commands can also be directed to LINK
Channel Service Unit Systems (LINK/CSU) connected to any node in the network.
Command format and supervisory port operational guidelines are described in this chapter.
Commands are discussed in the following chapters:
●
Support Commands, Chapter 4, discusses supervisory port operational commands and command files.
●
Display Commands, Chapter 5, describes the commands that provide status, statistical, and configuration information.
●
Configuration Commands, Chapter 6, describes the commands used to configure the
LINK/2+ System. This chapter also includes guidelines for performing configuration activities and typical configuration procedures.
●
Diagnostic Commands, Chapter 7, describes the commands that allow the user to test channels, intermachine links, modules, and alarm relays.
For a summary of all supervisory port messages, see Appendix A.
For information on accessing the supervisory port, see Chapter 2, Getting Started.

6/30/97
Structure of Commands
Command structure consists of:
●
Optional remote node designation
●
Instruction
●
Modifier
●
Range
The optional remote node designation lets you direct a command to a specific remote node. If a command is to be executed at the local node, the local node number is not required.
NOTE:
See the "Issuing Remote Commands" paragraphs for information on issuing remote commands in expanded networks.
The instruction is a 2- or 3-character abbreviation, for example, DEF for DEFINE and CLR for
CLEAR. The instruction part of the command is always required.
The modifier follows the instruction and specifies:
●
A particular physical part of the LINK/2+ System, e.g.:
CH = channel
DL = intermachine link
SP = supervisory port
●
A particular action, e.g.:
PG = pagination
CON = connection
PR = priority
Some commands require only one modifier. For example, the command:
SET PG where: SET = instruction
PG = modifier sets pagination on the supervisory terminal.
Other commands require two or three modifiers. For example, the command:
DEF CFB 1 SC1
L2UG
6/30/94
3-3
where: DEF= instruction
CFB 1 SC1 = modifiers defines station clock 1 as the primary clock source on the system clock fallback list.
The range part of the command further specifies the device on which the command is to be executed. The following paragraphs describe how ranges are specified.
Specifying a Node
When a command specifies a node, the range can include any combination of: xxxx = a single node xxxx,xxxx = multiple nodes xxxx-xxxx = a range of nodes in ascending order
* = all nodes. This selection must be entered alone.
For example, to display the routing parameters for nodes 2, 3, and 100 to 111, the command is:
DSP RTE 2,3, 100-111 where: DSP = instruction
RTE = modifier
2,3, 100-111 = range
Specifying a Module
When a command specifies a module, the Mainframe (nest) and slot number are both required.
The range can include any combination of: n:ss = a single slot n:ss,n:ss = multiple slots n:ss-n:ss = a range of slots in ascending order
* = all slots. This selection must be entered alone.
For example, to logically insert a module in slot 4 of Expander A Mainframe (nest 2), the command is:
INS 2:4 where: INS = instruction
2:4 = range
3-4
L2UG
6/30/94
Specifying an Intermachine Link
When a command specifies an intermachine link, only the slot number where the Interlink
Module is located is required. The range can include any combination of: ss = a single intermachine link ss,ss = multiple intermachine links ss-ss = a range of intermachine links in ascending order
* = all intermachine links. This selection must be entered alone.
For example, to display the intermachine link parameters for the Interlink Modules in slots 11 and 13, the command is:
DSP DL 11, 13 where: DSP = instruction
DL = modifier
11, 13 = range
Specifying a Channel
When a command specifies a channel, the Mainframe (nest), slot, and channel number are required. Depending on the command, the channel number could be: n:ss:c = I/O channel number (1-4) n:ss:cc = DS-0 channel number (1-31), X.50 DS-0 channel number (1-16)
VSM/VSM.1 channel number (1-31), VSM.3A channel number (1-8),
VSM.3B channel number (1-16), or VSM.5 channel number (1-12) n:ss:ccc = bypass channel number (1-511)
The range can include any combination of: n:ss:c = a single channel n:ss:c,n:ss:c = multiple channels n:ss:c-n:ss:c = a range of channels in ascending order n:ss:* = all channels on module in specified slot
* = all channels. This selection must be entered alone.
For example, to display channel parameters for channel 4 on the I/O module in slot 5 of
Expander B Mainframe (nest 3), the command is:
DSP CH 3:5:4
L2UG
6/30/97
3-5
where: DSP = instruction
CH = modifier
3:5:4 = range
To display channel parameters for all channels on the I/O modules in slots 10, 11, and 12 of the
Control Mainframe (nest 1), the command is:
DSP CH 1:10:1-1:12:4 where: DSP = instruction
CH = modifier
1:10:1-1:12:4 = range
Specifying an X.50 Subrate Channel
When a command specifies an X.50 subrate channel, the Mainframe (nest), slot, X.50 DS-0
(X.50 aggregate) channel, and the X.50 subrate channel number (1-20) are required.
The range can include any combination of: n:ss:cc:sr = a single X.50 subrate channel n:ss:cc:sr,n:ss:cc:sr = multiple X.50 subrate channels n:ss:cc:sr-n:ss:cc:sr = a range of X.50 subrate channels in ascending order n:ss:cc:* = all X.50 subrate channels in an X.50 DS-0 channel on module in specified slot
For example, to display the channel parameters for X.50 subrate channels 7 to 12 on X.50 DS-0 channel 8 of the XSM Module in slot 17 of the Control Mainframe (nest 1), the command is:
DSP XCH 1:17:8:7-1:17:8:12 where: DSP = instruction
XCH = modifier
1:17:8:7-1:17:8:12 =range
To display the channel parameters for all X.50 subrate channels on X.50 DS-0 channel 10 of the
XSM Module in slot 12 of the Control Mainframe (nest 1), the command is:
DSP XCH 1:12:10:* where: DSP = instruction
XCH = modifier
1:12:10:* = range

SUPERVISORY PORT OPERATIONAL GUIDELINES
The supervisory port recognizes several supervisory terminal control key editing functions which are used to support all phases of supervisory port operation; see Table 4-1 in Chapter 4, Support
Commands.
The following paragraphs explain how to enter commands, issue remote commands, issue external port (LINK/CSU) commands, and make menu selections.
Entering Commands from Supervisory Terminal
Use the following procedure to enter commands from the supervisory terminal:
1.
Ensure supervisory port prompt (Nxxxx>) is displayed. (xxxx is the local node number.)
If the prompt is not displayed, enter Control C character.
LINK/2+ System displays supervisory port prompt.
2.
Type complete command at the supervisory port prompt.
If you make a typing error, backspace by using the Backspace or DEL key or entering
Control H character(s), type the correct character(s), and then enter Control A or Control F character to move cursor to the end of the command line.
3.
Press RETURN key to enter the command.
●
If the command was entered incorrectly:
●
A question mark is displayed in lieu of the supervisory port prompt.
An up arrow points to the error.
Press the RETURN key and reenter the command.
If the command was entered correctly:
Command is executed.
Response, if any, is displayed.
Supervisory port prompt is displayed.
Issuing Remote Commands
NOTE:
In the command summary tables throughout this User’s Guide, a # in the "N" column indicates that a command can be issued to a remote node.
All commands entered through the supervisory port are directed to the local node unless the command is preceded with the remote node designation, NOD xxxx.
L2UG
6/30/94
3-7
NOTES:
A remote command will NOT be executed if any of the following conditions exist:
●
If the local node number entered is invalid, the message
"ILLEGAL SOURCE NODE" is displayed.
●
If the command is directed to an undefined node, a question mark is displayed and an up arrow points to the error. Press the
RETURN key to return to the supervisory port prompt.
●
If a route between the local and remote nodes has not been defined, the command is aborted. See "Define and Clear Routing
Table (DEF RTE, CLR RTE) Commands" and "Define and Clear
Subnetwork Routing Table (DEF SRT, CLR SRT) Commands" paragraphs in Chapter 6, Configuration Commands.
●
If a nonglobal gateway command is issued to another node in the same network and the remote node does not have the originator node number on its alarm notification list, the command is aborted.
●
If an intermachine link has failed, routing tables to a remote node are incorrect, intermachine link security is enabled, or an inbound intermachine link along the route is defined for
TRANSLATE=FULL or TRANSLATE=NO BYPASS, the message
"NO ACKNOWLEDGE" is displayed. The local LINK/2+ System will retry the command every 30 seconds. To abort the command immediately, enter Control C character or press BREAK key.
Intermachine links at a node defined with TRANSLATE=NO
BYPASS will not block messages terminating at that node.
●
If a command is issued to a node more than seven bypass hops from the source node, or a response to a command cannot locate the source node due to erroneous routing, the local LINK/2+
System will retry the command every 30 seconds. After 4 minutes, the retransmissions will stop and the message "NO RESPONSE -
CMD ABORTED" is displayed. To abort the command before the
4 minutes have elapsed, enter Control C character or press
BREAK key.
●
In a network with nodes that have different firmware levels, some commands may not be recognized by the older nodes. If a remote node does not recognize a command, a question mark is displayed at the local supervisory terminal. Press RETURN key to return to the supervisory port prompt.
Issuing External Port (LINK/CSU) Commands
A LINK/2+ supervisory terminal can issue commands to a LINK/CSU connected to any
LINK/2+ System in the network. The LINK/CSU command must be preceded by EP. For example, the following command is issued to the LINK/CSU at the local node:
EP D L 5
3-8
L2UG
6/30/94
where: EP = external port prefix
D L 5 = LINK/CSU command
To issue a command to a LINK/CSU connected to a remote node, precede the entire command with the remote node designation, NOD xxx. For example, the following command is issued to the LINK/CSU at node 50:
NOD 50 EP D L 5 where:
NOD 50 = remote node designation
EP = external port prefix
D L 5 = LINK/CSU command
For information on LINK/CSU commands, see the LINK/CSU User’s Guide.
NOTE:
The Network Module DIP switch K1-1 must be set to ON/CLOSED before the EP commands are accepted.
Making Menu Selections
For most commands used to define parameters, the supervisory terminal displays a menu from which parameter values are selected. To select parameter values from a menu:
1.
Enter complete command. System displays first line of current values. The cursor is immediately to the right of the first parameter value, Figure 3-3.
2.
Press the F key to scroll forward or press the B key to scroll backward through the parameter values until the desired value is displayed.

Stop Command File Execution (STP) Command
The STP command stops a currently executing command file from continuing, once the system processes the STP command.
No commands, following the STP command, in the command file sequence will execute.
Toggle Bank (TGL BNK) Command
The TGL BNK command is issued to a Network Module. This command switches execution of operational software from the Network Module’s current online flash EPROM bank to the current offline flash EPROM bank. For example, if the Network Module is currently executing from the operational software in bank B, it will execute from bank A after the TGL BNK command is executed.
Before switching to the other memory bank, the Network Module performs a checksum on the operational software in the new memory bank, and will only switch after confirming that the software in the new bank is satisfactory.
PRECAUTION: The TGL BNK command also resets the Network Module, but the online Network Module remains the online module after resetting.
Command:
[NOD xxxx] TGL BNK n:ss
Send Message (") Command
The " command sends up to 48 characters of text to the supervisory port of the specified remote node. If the remote node is unable to display the text message for any reason, the " command times out after 14 seconds and displays the message "BUSY" at the local supervisory terminal.

COMMAND FILE COMMANDS
Command files allow the user to replace complex commands, or a sequence of commands, with a single macro command that is stored in the database. The following paragraphs describe the commands for defining, displaying, editing, executing, and clearing command files.
Delete Command Lines (D) Command
The D command deletes a specified line or range of lines in a command file when the supervisory terminal is in command file edit mode.
Command at the CMD? prompt:
D {i or i-j} where: i = number of command line to be deleted i-j = range of command line numbers for lines to be deleted, where i < j.
Define/Clear Command File (DEF @) Command
The DEF @ command opens a new or existing command file for editing and displays the command file editor prompt for edit commands. Up to eight separate command files can be defined. Each command file can contain a maximum of 254 characters (including spaces and carriage returns). Each command file is given a unique 1-digit identifier from 1 to 8.
The edit commands available through the DEF @ command are also used to clear a command file.
Command:
DEF @ file where: file = specified command file (a number from 1 to 8)
The following guidelines apply when defining command files:
●
If more than 254 characters are entered in a command file, the message "Out of Space" is displayed when the editor is exited. Redefine the command file. See "Linking Command
Files" paragraph to program a command file of more than 254 characters.
●
A LINK/2+ System can be programmed to execute a command file repeatedly. See
"Repeating Command Files" paragraph.
●
Two special supervisory port commands are available only for use within a command file. See
"Terminal Control and Banner Command" and "Delay Time Command" paragraphs.
●

Execute Command File (@) Command
The @ command executes a command file. Command files can be executed either manually
or automatically at a specified time of day. The individual commands that were entered into the specified command file via the DEF @ command are executed one at a time in the order in which the commands were originally entered.
Commands:
@ file [/tt:tt:tt]
@ file [/tt:tt:tt mm-dd-yyyy]
@ file [/mm-dd-yyyy tt:tt:tt]
@ file [/mm-dd-yyyy] where: file = specified command file (a number from 1 to 8) tt:tt:tt = (optional) time in hours:minutes:seconds when the command file is to be executed (24-hour clock) tt:tt:tt mm-dd-yyyy = (optional) time in hours:minutes:seconds and date as month-day-year when the command file is to be executed mm-dd-yyyy tt:tt:tt = (optional) date as month-day-year and time in hours:minutes:seconds when the command file is to be executed
4-20
L2UG
6/30/97
mm-dd-yyyy = (optional) date as month-day-year when the command file is to be executed
If the @ command is entered without the time modifier, the command file is executed only once
(upon entry).
Time of Day Execution
If the time modifier, i.e., tt:tt:tt, is included in the @ command, the specified command file is executed once every 24 hours, at the time specified, until the time is cleared using the CLR @ command.
Time and Date Execution
If the time and date modifier is included in the @ command, the specified command file is executed once on the time and date specified.
Date Execution
If the date modifier is included in the @ command, the specified command file is executed on the date specified, at the time the command file was entered.
For example, to program the LINK/2+ System to execute command file 2 at 5:00 P.M. every day, enter:
@ 2/17:00:00 where: @ = instruction
2 = specifies command file 2
17:00:00 = sets execution time for 5 P.M.
Clear Preset Time (CLR @) Command
The CLR @ command clears the time that the LINK/2+ System is programmed to automatically execute a command file.
Command:
CLR @ file where: file = specified command file (a number from 1 to 8)
Only the time that the LINK/2+ System is programmed to execute the command file is cleared from the database, not the command file itself.
NOTE:
A reset to a nonredundant Network Module or loss of power to the
LINK/2+ System also clears the time at which a command file will automatically be executed.
L2UG
6/30/97
4-21
For example, to clear the preset time from command file 2, enter:
CLR @ 2 where:
CLR @ = instruction
2 = specifies command file 2
USING COMMAND FILES
The following paragraphs describe how to use command files more efficiently by linking command files, repeating a command file, and using the special commands that can only be used as instructions within a command file.
Linking Command Files
To enter a sequence of commands containing more than 254 characters, command files can be linked together. Enter the @ command as the final command in the current command file and specify the identification number of the command file to which you wish to link.
For example, Figure 4-3 shows how command file 5 is programmed so that the last instruction, i.e., @ 6, executes command file 6.
N0100> DEF @ 5
VALID COMMANDS ARE: DELETE, EDIT, INSERT, E(X)IT
Command File #5
1 DEF DST CH 1:8:*/N2 C1:10:*
2 NOD 2 DEF DST CH 1:10:*/N1 C1:8:8
3 DSC CH 1:9:11:9
4 @ 6
CMD? X
Figure 4-3. Typical Programming to Link Command Files
Repeating Command Files
To program a LINK/2+ System to execute a specified command file repeatedly, enter the @ command as the final command in the current command file and specify the identification number of the current command file.
To stop execution of a repeating command file, press BREAK key or enter Control C character.
For example, Figure 4-4 shows how to program the LINK/2+ System to repeatedly execute command file 4, which displays intermachine link status of the Interlink Module in slot 11.

VALID COMMANDS ARE: DELETE, EDIT, INSERT, E(X)IT
Command File #4

2 @ 4
CMD? X
Figure 4-4. Typical Programming to Repeat Command File
Delay Time (*) Command
The Delay Time (*) command is used to enter a time delay within a command file. After a * command is executed, the system waits the amount of time specified by the * command before executing the next command in the file.
Command:
*tt:tt:tt where: tt:tt:tt = time in hours:minutes:seconds (24-hour clock)
For example, Figure 4-5 shows a command file that displays intermachine link status for the
Interlink Module in slot 11 every 15 seconds.
NOTE:
The Delay Time command is a special supervisory port command that can only be entered as an instruction within a command file.

Figure 4-5. Typical Use of Delay Time Command
Terminal Control and Banner (&) Command
The & command is used to enter terminal screen control characters and text into a line of a command file. Typically, the control characters are used to clear the screen and position text that is used as a banner while a command file is being executed.
L2UG
6/30/97
4-23

Command:
&x
1
... x
254 where: x
1
... x
254
= up to 254 terminal screen control characters and alphanumeric characters that can be typed in a command file
To enter a terminal screen control character (e.g., home, clear, or cursor forward), press the appropriate key on the keyboard or enter the sequence of special characters specified by your terminal user’s manual. When the & key is entered as the first character on a line in a command file:
●
The terminal echoes the control characters and text on the screen as they are entered.
●
The terminal screen control functions are executed and text is displayed on the screen when the command file is executed.
For example, Figure 4-6 shows a typical example of how to program the LINK/2+ System to clear the supervisory terminal screen, return the cursor to the home position, and display the banner "DISPLAYING DATA LINK STATISTICS" each time command file 4 is executed.
All the key entries that follow the & command are displayed when the DSP @ command is entered, including terminal control character sequences, Figure 4-7.
NOTE:
The Terminal Control and Banner command is a special supervisory port command that can only be entered as an instruction within a command file.

DISPLAY DESTINATION CHANNELS (DSP DST, DSP DST CH, DSP
DST DS0, DSP DST XS0, DSP DST XCH) COMMANDS
The DSP DST * command displays the destination channel and connect status of all I/O channels, all DS-0, all X.50 DS-0 channels, and all X.50 subrate channels at a node. To display the destination channel and connect status of specified channels, use the following commands:
●
DSP DST CH command to display this information for specified I/O channels only
●
DSP DST DS0 command to display this information for specified DS-0 channels only
●
DSP DST XS0 command to display this information for specified X.50 DS-0 channels only
●
DSP DST XCH command to display this information for specified X.50 subrate channels only
Each command also indicates whether a channel connection was established as a result of a logical node translation and the intermachine link speed at which the connection was established.
If a bias route to the destination channel is defined, the bias intermachine link or bias integrated trunk bundle to be used is also displayed. See Figure 5-15 for a typical display.

DISC ERROR = Disconnected
incompatible parameters, no local/remote I/O module installed, or routing to destination node not defined
DISC GROOM = Disconnected due to grooming
DISC NO BW = Disconnected
no bandwidth available because:
- Bandwidth fully used
- No complete route to destination node
- Number of bypasses to destination node
exceeds channel delay threshold parameter
- A channel has a bias route programmed, but
the channel delay threshold parameter is not
large enough to use the bias route.
- Inoperative Bypass Module at intermediate
bypass node
- All of the bypass channels at one or more
bypass nodes are already in use.
- Bypass connect queue at intermediate node
is full.

DISC REV = Displayed when disconnect is due to the following:
- Channel’s ABM routing criteria are all default
values.
- The only violation is revision error.
For example, message would be displayed if a
DS-0 channel attempted to connect over a
LINK/1 System.

NOTE: During bundle dialing and alignment,
DSP DST DS0 response indicates that bundle is connected. Since bundle and intermachine link status is not available yet, the DSP ST BDL response indicates the bundle is not connected.
Upon completion of bundle dialing and alignment, the DSP ST BDL response will show bundle status.
LOCAL-L = Channel is connected via logical destination node number.
PEND = Channel is on connect queue waiting for initial connect attempt.
PEND reason = Channel is on connect queue waiting for connect attempt; reason can be any of the DISC reasons, for example, NO BW,
BUSY, etc.

DIAL LINK = dial link
EXPANSION FOR 1:ss = Interlink Module expanded
EXPANSION FOR 1:ss:cc = Bundle expanded
LINKBACK FOR 1:ss = Interlink Module backed up
LINKBACK FOR 1:ss:cc = Bundle backed up
NONE = Nondial-up service
BER - Bit error rate condition, where:
PEND = Bit error rate test is in progress, or
Integrated Trunk Module never synchronized to an integrated trunk.
VERY GOOD = Test passed; BER better than
1x10-5
GOOD = Test passed; BER between 1x10-5 and
1x10-4
FAIR = Test passed; BER between 1x10-4 and
1x10-3
POOR = Test failed; BER worse than 1x10-3
WINDOWS - The ratio of full BER windows to total number of BER windows is displayed on the same line as the BER. If all BER windows are full, the window information is not displayed. The total number of BER windows depends on data rate:
Data Rate
448 kbps and greater
Greater than 192 kbps and less than 448 kbps
192 kbps and below
Number of
BER Windows
32 windows
80 windows
160 windows
BER level changes are not checked and updated each time a window is updated, but only for window transition periods. This results in a delay in updating BER levels.
REMOTE BER - Remote bit error rate. N/A indicates integrated trunk is in loopback, or remote node has an earlier firmware revision that does not provide this information.
OOS - Out-of-sync condition, where:
L = Local node is out-of-sync.
R = Remote node is out-of-sync.
LR = Both ends of integrated trunk are out-ofsync. (ROS must have been detected prior to
LOS.)
blank = Link is synchronized.
LOOP - Loopback status of integrated trunk (See
Appendix A, Error and Status Messages, for messages.) Loopback time is also displayed.
FNS.= N/A - EIA functions: not applicable
(Not applicable for integrated trunk)
CONNECTIONS - Number of channel connections
PERCENT BW USED - Percent bandwidth used by the connections
AVAILABLE BW - Available bandwidth, in bps
VOICE BW USED - Voice bandwidth used, in bps
DATA BW USED - Data bandwidth used, in bps
FS - Number of supervisory frames sent
FR - Number of supervisory frames received
RT - Number of supervisory frames retransmitted
NR - Number of negative acknowledgments sent.
Indicates errors in supervisory data received.
BS - Number of bad sync characters received
OS - Number of out-of-sync conditions
NOTE: Error displays and counters are only cleared by a "/C" suffix to the DSP ST BDL command.
"/B" suffix clears the BER test by clearing the windows. Issuing /B will disconnect channels if present BER is less than user-specified link error performance rate.
During bundle dialing and alignment, DSP ST BDL response indicates bundle is not connected since bundle and intermachine link status is not available yet. However, DSP DST DS0 response indicates that bundle is connected. Upon completion of dialing and bundle alignment, DSP ST BDL response will show bundle status.

DISPLAY INTERMACHINE LINK STATUS (DSP ST DL) COMMAND
The DSP ST DL command displays bit error rate, out-of-sync conditions, satellite buffer status, loopback status, and supervisory band frame counts for the specified intermachine link(s), Figure
5-56, or integrated trunk bundle(s). The DSP ST DL command clears the BER window, clears counters, and clears satellite buffer phasor error history.
Command:
To issue the command to an Interlink Module, the command format is:
[NOD xxxx] DSP ST DL
{
* or ss[-ss]...
[
,ss[-ss]
]}
[option]
To issue the command to an Integrated Trunk Module, the command format is:
[NOD xxxx] DSP ST DL
{
* or 1:ss:cc[-1:ss:cc]...
[
,1:ss:cc[-1:ss:cc]
]}
[option] where option is one of the following:
/B = clears BER window
/C = clears counters and satellite buffer phasor error history
NOTE:
Issuing /B will disconnect channels if present BER is less than userspecified link error performance rate.
The displayed bandwidth percentage used by the connections may differ slightly due to rounding method used on Interlink Module to
Integrated Trunk Module intermachine links.
For simplex intermachine link connections, the DSP ST DL command shows logical node translation status at the transmitting node only, not at the receiving node.

DISPLAY AND CLEAR TIME-STAMPED ALARM LIST (DSP TAQ, CLR
TAQ) COMMANDS
The DSP TAQ command displays alarms that are currently in the TAQ alarm list as well as their associated time-stamp. Alarms are displayed in FIFO order. Once the alarm list is filled, each successive new entry will force the oldest entry from the list until the list is cleared.
The CLR TAQ command clears the time-stamped alarm list. See Appendix A, Error and Status
Messages, for a description of each alarm.
Commands:
[NOD xxxx] DSP TAQ
[
a[-a]...
[
,a[-a]
]
]
where: a = alarm number or:
[NOD xxxx] DSP TAQ [/C] where: /C = clears the alarm list after the time-stamped alarms are displayed.
[NOD xxxx] CLR TAQ
Two types of alarms are reported by the LINK/2+ System, state alarms and event alarms:
•
State alarms, once they occur, are logged and a start of state alarm is generated. State alarms are then continually monitored by the system until the alarm condition returns to a non-alarm state, at which time an end of state alarm is generated.
•
Event alarms are logged each time they occur.
Typical DSP TAQ commands are illustrated in Figure 5-68.
NOTE:
Alarm 12 will only be posted on the initial failure of a channel to connnect. While the channel remains in the retry queue and continues to attempt a connection, additional alarm 12’s will not be generated.
If a connect channel command is subsequently issued to that channel before it connects, however, alarm 12 will be posted again.

Configuration Commands
LINK/2+ Systems are preprogrammed according to the configuration worksheets submitted with the order. Initial configuration of a LINK/2+ System requires a configuration planning process, which is discussed in the LINK/2+ Configuration Planning Manual.
Subsequent changes in the network may require configuration changes or complete reconfiguration of one or more nodes. This chapter discusses the commands used to perform typical configuration activities, provides guidelines for performing configuration activities, and describes all supervisory port configuration (programming) commands. Configuration commands are used to:
●
Define system, intermachine link, DS-1/E-1, ISDN D-channel, quality, DS-0, Link Framing
Module, and I/O channel parameters
●
Define routing
●
Define bundle configurations
●
Define channel connections and broadcast/polling connections
●
Define ABM, speed, and voice profiles
●
Connect and disconnect channels
The supervisory port configuration commands are listed in Table 6-1. Commands are in alphabetical order by command mnemonic. Parameters that can be programmed using the supervisory terminal are described in the Configuration Planning Manual.
TYPICAL CONFIGURATION ACTIVITIES
The examples in this chapter guide the user in:
●
Verifying parameters
●
Changing parameters
●
Adding modules
●
Adding a node to the network or reconfiguring a node
Before beginning any configuration task:
❒ Obtain a copy of each affected configuration worksheet for the node(s) to be programmed.
❒ If programming active LINK/2+ System(s), determine what effect the programming operations will have on data flow, and notify users as necessary.

Verifying Parameters
Table 6-2 shows the typical activities needed when verifying system level, intermachine link,
DS-1, ISDN D-channel, and channel programming. See Chapter 5, Display Commands, for sample displays of the commands used in Table 6-2.
Verifying parameters will not disrupt data flow.
Changing Parameters
Tables 6-3 through 6-18 show typical activities needed when changing:
●
System parameters
●
Intermachine link parameters and Integrated Trunk Module DS-1 parameters
●
Routing
●
Voice Processor DS-1/E-1 parameters, quality parameters, and DS-0 parameters
●
Channelized Services Processor DS-1/E-1 parameters, quality parameters, master DS-0 parameters, and bundle configuration
●

Adding Modules
In general, adding a module requires the following activities:
●
If a module must be removed or relocated before the new module can be installed, use the DEL command to delete database entries for the module being removed.
●
Use the RMV and INS commands to logically remove and insert modules.
●
Define database parameters for the modules that have been added or relocated:
For Interlink Modules, define intermachine link parameters and routing tables. See Tables
6-4 and 6-5.
For Integrated Trunk Modules, define DS-1/E-1 parameters, bundle configurations, proprietary and nonproprietary bundle parameters, channel connections, D-channel parameters, and routing tables. See Tables 6-4 and 6-5.
For Voice Processors, define DS-1/E-1 parameters, quality parameters, DS-0 channel parameters, and channel connections. See Tables 6-6, 6-7, and 6-12.
For Channelized Services Processors, define DS-1/E-1 parameters, quality parameters, master DS-0 channel parameters, bundle configuration, and channel connections. See
Tables 6-8, 6-9, 6-10, and 6-12.
For Voice Server Modules, use the SET VSM command to define the module.
For I/O modules, define channel connections and parameters. See Tables 6-11 and 6-12.
For X.50 Server modules, use SET XSM command to define the module, then define channel connections and parameters. See Table 6-18.
For more detailed information on adding modules to an existing LINK/2+ System, see Installing
Additional Modules chapter in the LINK/2+ Installation and Maintenance Manual, which provides step-by-step procedures covering the physical installation as well as the programming activities required for each type of module.

GUIDELINES FOR PERFORMING CONFIGURATION ACTIVITIES
Maintaining Configuration Records
For proper network maintenance and control, an accurate description of each node in the network is vital. To provide a record of node configuration:
●
Update the configuration worksheets each time a configuration change is made.
●
Maintain a chronological log of configuration activities showing the date, reason, and individual associated with each change.
●
Update database file archives using the Database Backup procedure in Chapter 2, Getting
Started.
●
Verify database file archives integrity with the CHECKDB.EXE program (provided with the
LINK/2+ operational software floppy disk package).
Performing Configuration Activities from a Local or Remote Site
Because most supervisory port commands can be directed to a remote node, the following approaches can be taken to configure a network:
●
Configuration activities can be performed from the supervisory terminal at a central LINK/2+
System using remote commands. This centralized approach is especially useful for configuration tasks that affect several nodes in a network. To issue remote configuration commands from a local supervisory terminal:
The remote node must have the intermachine link security parameter disabled. See "Define
Intermachine Link Parameters (DEF DL) Command" and "Define Proprietary Bundle
Parameter (DEF BDL PR) Command" paragraphs.
The local supervisory port must be designated as a gateway port. See Network Module chapter in the LINK/2+ Installation and Maintenance Manual.
The node number of the remote node must be defined. See "Define Node Number (DEF
NOD) Command" paragraph.
The local node number must be on the alarm notification list of the remote node. See
"Define Alarm Notification List (DEF ALM) Command" paragraph.
At least one route between the local and remote nodes must be defined for each node in the path. See "Define and Clear Routing Table (DEF RTE, CLR RTE) Commands" paragraph.
●
Configuration activities can be performed at each LINK/2+ System using a local supervisory terminal. Local configuration changes are allowed as long as the local supervisory port is designated as a gateway port.
●
Configuration activities can be performed using the TIME/VIEW NMS connected to the
LINK/2+ System.
L2UG
6/30/94
6-41
Parameter Effectivity
Parameter changes take effect as follows:
●
System parameters—Changes to most system parameters are implemented immediately upon entry of the command.
Exceptions are:
Intermachine link out-of-service timer; requires reset of affected Interlink Module(s). For
Integrated Trunk Modules, resetting one proprietary bundle changes the out-of-service timer for all proprietary bundles on the module. Affects intermachine links with individual outof-service timer programmed as SYS only.
System maximum phasor size; requires disconnect of affected channels to change, and subsequent reconnect of those channels to take effect
System I/O parameter; requires disconnect of affected channels to change, and subsequent reconnect of those channels to take effect
Most system parameters can have different values at each node, so changes made at one node do not necessarily require changes at another node.
●
Intermachine link parameters—Changes to most intermachine link parameters are not implemented until the Interlink Module or the bundle(s) of the Integrated Trunk Module is reset. Exceptions are satellite delay, subrate multiplexing, security, encryption, group, alarm threshold, Link Framing Module slot/bundle, logical node translation, and node to translate, which take effect immediately. Most intermachine link parameters must be the same at both ends of the intermachine link, so changes made at one node usually require changes at another node.
●
DS-1/E-1 parameters—Changes to DS-1/E-1 parameters are not implemented until the
Integrated Trunk Module, Voice Processor, or Channelized Services Processor for that trunk is reset. Usually, the trunk is connected to a channel bank, PBX, digital cross-connect, or fractional service provider access point, so changes made at one Integrated Trunk Module,
Voice Processor, or Channelized Services Processor do not require changes anywhere else in the network.
●
DS-0 and I/O channel parameters—Channels should be disconnected before DS-0 and I/O channel parameters are changed. After parameter changes are made, the channels must be reconnected to implement the changes. Exceptions are the echo cancellation and transmission level point parameters for the Enhanced Voice Module, Foreign Exchange Station Module, and
Foreign Exchange Office Module. Some channel parameters must be the same at both ends of the channel connection, so changes made at one node may require changes at another node.
●
Bundle configurations—Changes to Channelized Services Processor and Integrated Trunk
Module bundle configurations may require changes to the master DS-0 channel parameters and channel parameters at the terminator end of the connection. See Digital Voice and Channelized
Services Parameters chapter and Integrated Trunk Parameters chapter in the Configuration
Planning Manual for configuration guidelines.
6-42
L2UG
6/30/94
●
Broadcast/polling connections—Changes to master broadcast/polling channel connections require that the broadcast/polling group members, originator host channel, and master broadcast/polling channel are disconnected. After parameter changes are made, all channels must be reconnected to implement the changes.
●
Voice Server Module connections—Changes to the speed parameter for channels processed by a Voice Server Module require that the channels be disconnected before the speed is changed. After the change is made, the channels must be reconnected to implement the change.
●
Link Framing Modules (Models LFM.3, .10, .11, .12, .14) —Parameters and configuration do not take effect until the module is reset with the RST n:ss command.
●
D-Channel Module—Parameters do not take effect until the module is reset with the RST n:ss command.
●
Voice profiles—Changes to voice profiles do not affect associated channels until the channels are disconnected then reconnected.
●
Speed profiles—Changes to speed profiles do not affect associated channels until the channels are disconnected then reconnected.
●
Before making configuration changes, display parameters to verify current values and slot locations of channels.
●
After making configuration changes, display parameters to verify that changes are correct.
Record changes on configuration worksheets.

1/30/95
destination node. Up to seven bypass nodes between the originating node and the destination node are allowed.
/B = overrides the first path number and specifies the corresponding backup bundle instead
/X = overrides the first path number and specifies the corresponding expansion bundle instead
NOTE:
The CON DR command is not supported for Isochronous
Communication Module I/O channels.
See Figure 6-1 for an example of the CON DR command.
If a routed channel encounters an intermachine link operating in simplex mode, the channel may not be routed according to the specified path.
The route established by the CON DR command is NOT stored in the database and will be lost if the specified channel is subsequently disconnected and connected.
The CON DR command can be implemented only at the originator end of a channel. Use the DSP
CH, DSP MDS0, or DSP DS0 command to determine which end of the channel is the originator.
For diagnostic purposes, CON DR connections can be made over an intermachine link that is in loopback.
NOTE:
If the CON DR command is issued to a channel while a previous CON
DR command is still being processed, the message "CONNECT
QUEUE IN USE" is displayed.
Connect DS-0 Channel (CON DS0) Command
See "Connect and Disconnect Channel (CON BDL, CON CH, CON DS0, DSC BDL, DSC CH,
DSC DS0) Commands" paragraph.

CON PRO/D
To disconnect all channels using ABM profiles 1, 5, and the default ABM profile, enter:
DSC PRO 1,5/D
Define Alarm Notification List (DEF ALM) Command
The DEF ALM command defines the alarm notification list for a node. The alarm notification list specifies the remote node(s) that the local node must notify when an alarm occurs. An alarm message is automatically displayed on an idle supervisory terminal at the specified remote node(s) when an alarm occurs (providing the SET MUM REM command has not been implemented) and is logged in the alarm table.
The alarm notification list also specifies the remote nodes that can issue nonglobal gateway commands to the local node.
Command:
[NOD xxxx] DEF ALM
NOTE:
When the remote command is used, the local node should be placed on the alarm notification list to ensure that subsequent gateway commands are accepted.
After the command is entered, the supervisory port prompts the user to enter node numbers, Figure
6-2. Up to 16 node numbers can be entered on the alarm notification list. Press the RETURN key at a blank entry to terminate the list. If a Control C character is entered when defining a node’s alarm notification list from a remote node, no entry is made on the list. If a Control C character is entered when defining a node’s alarm notification list locally, the last node entered is not saved to the list.

Define Integrated Trunk Module Bundle Parameters (DEF BDL NPR,
DEF BDL PR) Commands
The DEF BDL NPR and DEF BDL PR commands display the current Integrated Trunk Module bundle configuration parameters and allow the user to change parameter values in the database for the specified Integrated Trunk Module. The DEF BDL NPR command displays the current nonproprietary bundle parameters; the DEF BDL PR command displays the current proprietary bundle parameters. The commands are always issued to the master DS-0 of any bundle.
Commands:
[NOD xxxx] DEF BDL NPR
{
* or 1:ss:cc[-1:ss:cc]...
[
,1:ss:cc[-1:ss:cc]
]}
[NOD xxxx] DEF BDL PR
{
* or 1:ss:cc[-1:ss:cc]...
[
,1:ss:cc[-1:ss:cc]
]}
After the command is entered, the supervisory port displays the current nonproprietary, Figure 6-
3A, or proprietary, Figure 6-3B, bundle parameters for the specified Integrated Trunk Module.
Select new parameters per "Making Menu Selections" paragraph in Chapter 3, General
Information. See the Integrated Trunk Parameters chapter in the Configuration Planning Manual for parameter values.
If more than one channel or a range of channels is entered in the command, the supervisory port displays the parameters of the first channel specified. After the new parameter values have been entered, the parameters of all specified channels will be overwritten with the bundle parameter values that are displayed.
NOTE:
Channels must be disconnected before the DEF BDL NPR command is issued. After the command is issued, the bundle must be reconnected for the changes to take effect.
Channels should be disconnected before the DEF BDL PR command is issued. After the command is issued, reset the bundle with the RST
BDL command to effect the changes. The channels must then be reconnected.
If a DS-0 channel is connected when a remote DEF BDL NPR command is issued, the command is aborted and the message
"CONNECTION EXISTS, CMD ABORTED" is displayed.
If a DS-0 channel within a range is connected, execution of a local
DEF BDL NPR command will update only the disconnected channel parameters.
The Integrated Trunk Module proprietary bundle uses only frame mode 2.

Define Bias Routing (DEF BIAS CH, DEF BIAS DS0) Commands
The DEF BIAS CH and DEF BIAS DS0 commands define the bias route (first intermachine link) over which a channel will be connected to a remote node. The DEF BIAS CH command defines the bias routing for I/O channels. The DEF BIAS DS0 command defines bias routing for Voice
Processor, Channelized Services Processor, and Integrated Trunk Module DS-0 channels or bundled DS-0 channels.
NOTE:
To define bias routing for X.50 DS-0 channels, use the SET BIAS XS0 command.
Commands:
[NOD xxxx] DEF BIAS CH n:ss:c[-n:ss:c]...
[
,n:ss:c[-n:ss:c]
]
/routing
[NOD xxxx] DEF BIAS DS0 n:ss:cc[-n:ss:cc]...
[
,n:ss:cc[-n:ss:cc]
]
/routing where routing is one of the following:
Lss[:cc] = the intermachine link number and bundle number (optional) to which all channels in the specified range of channels will bias
Lss[:cc]/O = only the odd-numbered channels within the specified range of channel numbers will bias to the intermachine link and bundle number (optional) specified in the command
Lss[:cc]/E = only the even-numbered channels within the specified range of channel numbers will bias to the intermachine link and bundle number (optional) specified in the command
OFF = the specified channels will terminate bias routing
OFF/O = only the odd-numbered channels within the specified range of channel numbers will terminate bias routing
OFF/E = only the even-numbered channels within the specified range of channel numbers will terminate bias routing
If the intermachine link specified in the command is out-of-service, then the next intermachine link in the routing table is selected. Every intermachine link in the routing table is attempted before the biased intermachine link is retried. The channel is not placed on the retry queue until every intermachine link in the routing table is tried once.
If the intermachine link selected in the command is not defined or is not listed in the routing table to the destination node, then the LINK/2+ System will attempt connection over the primary, nonbiased route.
Some applications of bias routing include the following:
●
An alternative to the CON DR command: The route defined with the DEF BIAS command remains in the database, while the route defined using the CON DR command will be lost if the channel is subsequently disconnected and reconnected.
●
Channel redundancy: Route two channels with the same destination over two different intermachine links.
●
Route avoidance: Bias route to ensure that less desirable routes are taken only as a last resort.
6-56
L2UG
6/30/94
●
Load sharing: Bias routing can be used to distribute channels over several intermachine links.
Without bias routing, the primary route is always the first one attempted.
NOTE:
The bias routing parameters are defined for originator channels only.
Channels must be disconnected before the DEF BIAS CH and DEF
BIAS DS0 commands are issued. After the commands are issued, the channels must be reconnected for the changes to take effect.
Define System Clock Fallback List (DEF CFB) Commands
The DEF CFB commands define the system clock fallback list, which specifies the primary system clock source and two fallback clock sources.
Commands:
[NOD xxxx] DEF CFB 1 clock
[NOD xxxx] DEF CFB 2 clock
[NOD xxxx] DEF CFB 3 clock
Define the three system clock sources by entering each of the following commands:
DEF CFB 1 clock - Clock fallback 1 (primary) source
DEF CFB 2 clock - Clock fallback 2 source
DEF CFB 3 clock - Clock fallback 3 source
All three commands must be entered. See System Parameters chapter in the Configuration
Planning Manual for guidelines on clock source selection. The choices for the clock parameter are:
CH 1:ss:c = synchronous channel receive clock
DLR ss = intermachine link receive clock
DLT ss = intermachine link transmit clock
DRI ss = intermachine link independent receive clock
DS1 n:ss = DS-1 trunk clock
DS1 n:ss/SC1 = DS-1 trunk clock with Voice Processor output to Network Module station clock 1
DS1 n:ss/SC2 = DS-1 trunk clock with Voice Processor output to Network Module station clock 2
INT = internal 6 MHz oscillator
LFM n:ss = NTT High-Speed Secondary Service trunk clock (from LFM.14 Module)
LFM n:ss/SC1 = NTT High-Speed Secondary Service trunk clock with LFM.14 Module output to Network Module station clock 1
LFM n:ss/SC2 = NTT High-Speed Secondary Service trunk clock with LFM.14 Module output to Network Module station clock 2
SC1 = Network Module station clock 1 input
SC2 = Network Module station clock 2 input
SKP = skip clock source (indicates that this clock fallback entry does not have a clock source and is not checked when a clock failure occurs)
L2UG
6/30/94
6-57
6-58
NOTE:
Up to two SKP clock fallback entries are allowed. At least one clock fallback entry must specify a clock source.
If all system clock sources are incorrectly defined, e.g., slot number specified for DLR or DLT clock is not an Interlink Module, the internal clock is used as the system clock.
Some typical clocking arrangements are as follows:
●
Clock fallback 1, 2, and 3 are all independent clock sources. If clock fallback 1 (primary) fails, clock fallback 2 is automatically used as the system clock. If clock fallback 2 fails, clock fallback 3 is automatically used as the system clock. If clock fallback 3 fails, the LINK/2+
System will attempt to use the original primary clock fallback 1 source. If all clocks on the fallback list fail, the internal clock is used until one of the clocks on the fallback list becomes functional.
●
Clock fallback 1 and 2 are independent clock sources, and clock fallback 3 is a SKP clock source entry. If clock fallback 1 (primary) fails, clock fallback 2 is automatically used as the system clock. If clock fallback 2 fails, the LINK/2+ System will attempt to use the original primary clock fallback 1 source. If all clocks on the fallback list fail, the internal clock is used until one of the clocks on the fallback list becomes functional.
●
Clock fallback 3 is an independent clock source and clock fallback 2 is a dependent clock source. When clock fallback 1 (primary) fails, clock fallback 3 is automatically used as the system clock source; the LINK/2+ System will attempt to use an independent clock source before a dependent clock source. If clock fallback 3 fails, clock fallback 2 is automatically used as the system clock. If clock fallback 2 fails, the LINK/2+ System will attempt to use the original primary clock fallback 1 source. If all clocks on the fallback list fail, the internal clock is used until one of the clocks on the fallback list becomes functional.
The following restrictions apply to system clock sources:
●
If the internal clock is on the clock fallback list, automatic fallback to the next clock source is inhibited. Use the SET CLK command to direct the LINK/2+ System to use another clock source as the system clock.
●
If a synchronous channel receive clock is a system clock source, enter n:ss:c to specify the channel. Only channels in the Control Mainframe (nest 1) can be used. The specified channel must be defined as a DTE with an external clock. The channel speed should be at least 2400 bps and must be a multiple of 400 Hz.
●
If an intermachine link receive clock (DLR or DRI) or intermachine link transmit clock (DLT) is a system clock source, enter slot number ss to specify the location of the Interlink Module for that intermachine link.
●
If Network Module station clock 1 or station clock 2 is a system clock source, define the station clock speed with the DEF SC command before entering SC1 or SC2 on the clock fallback list.
●
If a DS-1 trunk clock (DS1) is a system clock source, enter nest and slot number n:ss to specify the location of the Voice Processor, Integrated Trunk Module, or Channelized Services
Processor for that DS-1 trunk. If the Voice Processor is in an Expander Mainframe, the DS-1 clock must be externally input to the Network Module via station clock 1 (/SC1) or station clock 2 (/SC2).
L2UG
6/30/94
●
If an Integrated Trunk Module is selected as a clock fallback, the only valid choice for the
clock parameter is DS1 n:ss.
Define Channel Parameters (DEF CH/, DEF DS0, DEF MDS0)
Commands
The DEF CH/, DEF DS0, and DEF MDS0 commands display the current channel parameters for the specified channel(s) and module type, and allow the user to change parameter values in the database. Use the DEF CH/ command for I/O module channels. Use the DEF DS0 command for
Voice Processor DS-0 channels. Use the DEF MDS0 command for Channelized Services
Processor master DS-0 channels.
Commands:
[NOD xxxx] DEF CH/module n:ss:c[-n:ss:c]...
[
,n:ss:c[-n:ss:c]

where: DCI = Dual Isochronous Module
DSC = Dual Synchronous Module
EVM = Enhanced Voice Module
FXO = Foreign Exchange Office Module

QVM.6 = QVM.6 Voice Module
NOTE:
Channel parameters for an entréeLINK+ FXO.3 Foreign Exchange
Office Module cannot be configured from a LINK/2+ node. This module must be configured via the supervisory port of an entréeLINK+ node or from a TIME/VIEW Network Management

After the DEF CH/, DEF DS0, or DEF MDS0 command is entered, the supervisory port displays the current channel parameters, Figure 6-4, for the specified channel. Select new parameters per
"Making Menu Selections" paragraph in Chapter 3, General Information. See the chapters on defining channel parameters in the Configuration Planning Manual for parameter values.
If more than one channel or a range of channels is entered in the command, the supervisory port displays the parameters of the first channel specified. After the new parameter values have been entered, the parameters of all specified channels will be overwritten with the parameter values that are displayed, provided these channels are on the same module type as the displayed channel.
L2UG
8/30/94
6-59
NOTE:
Channels must be disconnected before the DEF CH/, DEF DS0, and
DEF MDS0 commands are issued. After the commands are issued, the channels must be reconnected for the changes to take effect.
If a DS-0 channel is connected when a local or remote DEF DS0 or
DEF MDS0 command is issued, the command is aborted and the message "CONNECTION EXISTS, CMD ABORTED" is displayed.
If a DS-0 channel within a range is connected, execution of a local or
remote DEF DS0 or DEF MDS0 command will update only the disconnected channel parameters.

NOTE:
To connect channels via a DS-1 trunk, a Voice Processor, Integrated
Trunk Module, or Channelized Services Processor must be in both the local and remote nodes. A connection must be defined between the channels and Voice Processor or Channelized Services Processor
DS-0 channels at the local node, and the channels and Voice
Processor or Channelized Services Processor DS-0 channels at the remote node. The CON DS0 or CON CH command must be issued to the originator channels at the local and remote nodes.
Channel connections must be defined in the LINK/2+ System database for each end of the channel. For example:
●
Single channel connection—To define a connection between I/O channel 1:5:1 at node 12 and
DS-0 channel 1:6:10 at node 21, enter the following commands:
NOD 12 DEF DST CH 1:5:1/N21 DS0
NOD 21 DEF DST DS0 1:6:10/N12 C1:5:1
●
Range of channel connections—To define connections between channels 1:5:1-1:5:4 at node
12 and channels 1:6:1-1:6:4 at node 21, enter the following commands:
NOD 12 DEF DST CH 1:5:*/N21 C1:6:*
NOD 21 DEF DST CH 1:6:*/N12 C1:5:*
●
Voice Processor or Channelized Services Processor connections—To define a connection between I/O channel 1:16:1 at node 6 and I/O channel 1:12:1 at node 10 via a DS-1 trunk, where Channelized Services Processor DS-0 channel 1:8:4 is at node 6 and Channelized
Services Processor DS-0 channel 1:9:8 is at node 10, enter the following commands:
NOD 6 DEF DST CH 1:16:1/N6 DS0
NOD 6 DEF DST DS0 1:8:4/N6 C1:16:1
NOD 10 DEF DST CH 1:12:1/N10 DS0
NOD 10 DEF DST DS0 1:9:8/N10 C1:12:1
●
D-channel connections—To define a connection between D-channel 1:17:1 at node 6 and
Integrated Trunk Module DS-0 1:10:24 at node 6, enter the following commands:
NOD 6 DEF DST DS0 1:10:24/N6 C1:17:1
NOD 6 DEF DST CH 1:17:1/N6 D1:10:24
Channels must be disconnected before the DEF DST CH and DEF DST DS0 commands are issued. After the commands are issued, the channels must be reconnected for the changes to take effect.
6-71
To implement the channel connection changes, the channel(s) must be disconnected and then connected as follows:
●
If a channel is currently disconnected, issue the DEF DST CH, DEF DST DS0, or DEF DST
XS0 command to change the channel connections. Then, enter the CON CH or CON DS0 command to connect the channels and implement the changes.
●
If a channel is currently connected, enter the DSC CH or DSC DS0 command to disconnect the channel. Issue the DEF DST CH, DEF DST DS0, or DEF DST XS0 command to change the channel connections. Then, enter the CON CH or CON DS0 command to connect the channels and implement the changes.

The DEF MM command defines a node as a master clocking node for the network and assigns a clock priority to the node. Up to 16 nodes can be defined as master clocking nodes. Each master clocking node should be defined with a different clock priority.
Command:
[NOD xxxx] DEF MM cpr where: cpr = clock priority of the specified master clocking node. Clock priority is from 1 to 16, where 1 is the highest clock priority.
For example, to define node 18 as a master clocking node with priority 1, enter:
NOD 18 DEF MM 1
The purpose of multiple master clocking node(s) is to guarantee under all conditions that there will be an independent clock source in the network. If all independent clock sources in all multiple master clocking nodes are inoperable, the multiple master clocking node with the highest priority will use its internal oscillator to provide timing to the network until an independent clock source at any multiple master clocking node becomes operational.

Define Broadcast/Polling Master Channel (DEF MSR POL) Command
The DEF MSR POL command defines the broadcast/polling master channel. The specified channel will become the broadcast/polling master channel if the following requirements are met:
●
A previous connection for the channel does not exist.
●
The channel is defined for broadcast/polling.
●
The channel is not a member of a broadcast/polling group.
The master broadcast/polling channel will connect to the host channel at the originating node. All broadcast/polling members associated with a master broadcast/polling channel communicate to the host channel via the connection established between the host channel and the master broadcast/polling channel.
Command:
[NOD xxxx] DEF MSR POL n:ss:c[-n:ss:c]...
[
,n:ss:c[-n:ss:c]
]
For example, to define channel 1 of the Quad Synchronous Processor located in nest 1, slot 16 as a master channel, enter:
DEF MSR POL 1:16:1
NOTE:
Channel(s) must be disconnected before the DEF MSR POL command is issued. After the command is issued, the channel(s) must be reconnected for the changes to take effect.
Define Node Number (DEF NOD) Command
The DEF NOD command enters the node number of the local LINK/2+ System in the database.
The node number identifies the LINK/2+ System in all remote commands and on the alarm notification list.
Command:
DEF NOD xxxx
The DEF NOD command must be entered locally at each LINK/2+ System.
Upon completion of the DEF NOD command, the node must be reset.
Define Intermachine Link Out-Of-Service Time (DEF OOS) Command
The DEF OOS command defines the time in seconds that an intermachine link may be continuously out-of-sync before the intermachine link is declared out-of-service. This parameter applies to all intermachine links at a node.
6-80
L2UG
6/30/94
Command:
[NOD xxxx] DEF OOS tt where: tt = 2, 4, 6, 8, 10, 12, 14, or 16 seconds
When an intermachine link is out-of-sync beyond the specified time, the out-of-service alarm 07 is displayed on an idle supervisory terminal and also logged in the alarm table. If the out-of-service time is changed, the Integrated Trunk Module DS-1 database receives the update through a reset of the module or of any proprietary bundle on the module. The Interlink Module receives the update through a reset of the module.
Define and Clear Broadcast/Polling Group Members
(DEF POL, CLR POL) Commands
The DEF POL command defines the specified channel(s) to a broadcast/polling group with the specified master channel. The channel will become a member of the broadcast/polling group if the following requirements are met:
●
The channel is defined for broadcast/polling.
●
The channel is not defined and connected to another broadcast/polling group. If the channel is defined to another broadcast/polling group but is not connected, the channel is redefined to the specified broadcast/polling group.
●
The channel speed, mode of transmitting EIA functions, and broadcast/polling sensitivity mode are the same as those defined for the master channel.
●
A previous connection for the channel does not exist.
●
The channel is not a master channel.
The CLR POL command disconnects and clears the specified channel from the associated broadcast/polling group. A master channel cannot be disconnected and cleared if the following conditions exist:
●

Define System Connect Retry Timer (DEF RET) Command
The DEF RET command defines the time the Network Module at an originator node will wait before reattempting to connect to the channel at the terminator node when:
●
Channels become disconnected because an intermachine link has failed.
●
The previous attempt to connect failed because bandwidth was not available.
●
Channel was groomed by translation node.
Command:
[NOD xxxx] DEF RET zz where: zz = a retry timer number (00, 02 to 16) that corresponds to a time in seconds given by: retry timer number x 15 = waiting time in seconds
NOTE:
An exception is the retry timer number 00. This number produces a waiting time of 2 seconds for the first reconnect attempt. The timer is changed to 8, 16, and 30 seconds for each subsequent attempt.
For example, if the retry timer is 02, the actual Network Module waiting time in seconds before reattempting to connect a channel is:
02 x 15 = 30 seconds

Define and Clear Routing Table (DEF RTE, CLR RTE) Commands
The DEF RTE command defines a routing table that specifies all possible intermachine link paths from an originating node (physical node) to a destination node (physical or logical node). Routing tables must be defined so that remote commands and channel connections can be executed.
Defining all possible paths in the routing table helps to ensure that communication between two nodes will continue even in the event of multiple intermachine link failures.
Command:
[NOD xxxx] DEF RTE xxxx[/F] where: /F = allows the user to define the routing paths in any order of path delay
To remotely define a routing table, at least one path to the remote supervisory terminal must be programmed at each node in the path. Typically, these routing tables are preprogrammed prior to shipment.
After the command is entered, the supervisory port prompts the user to define the paths from the originating node to the specified destination node. Each path is defined by entering:
●
Interlink Module slot number, or Integrated Trunk Module proprietary bundle slot and bundle number
●
Path delay number
The path delay is the minimum number of bypass nodes between the originating node and the destination node. For point-to-point connections, the path delay number is 0. If the DEF RTE
command is issued without the /F modifier, paths must be defined in ascending order of path delay.
After the last intermachine link number and path delay are entered, the define routing table command is exited by pressing the RETURN key.
To illustrate, Figure 6-16 shows a typical network. The routing from physical node 5 to physical node 4 or logical node 10, for example, can take four possible paths—link 3, 5:7, 7, or 9.
If the DEF RTE command is issued WITHOUT the /F modifier, the routing is defined as follows:
●
When link 5:7 is used, the path delay is 0, i.e., point-to-point connection. Therefore, the path using link 5:7 should be the first entry in the routing table.
●
When link 7 or 9 is used, the path delay is 1, i.e., one other node —node 7—must be bypassed.
Since both paths have the same path delay, decide which intermachine link is preferable and enter that intermachine link path first, then enter the other intermachine link path in the routing table.
●
When link 3 is used, the path delay is 3, i.e., three other nodes —nodes 3, 1, and 2—must be bypassed. This path has the longest path delay and should be entered last in the routing table.

If the DEF RTE command is issued WITH the /F modifier, the paths can be entered in any order, e.g., link 3 can be the first entry in the routing table even though that path has the longest path delay.
Figure 6-17 shows sample DEF RTE commands for defining the routing table from physical node
5 to physical node 4.
Observe the following guidelines when defining routing tables:
●
Up to eight different paths can be defined in each routing table.
●
An intermachine link number may appear only once in the same routing table.
●
For an intermachine link with redundant Interlink Modules, enter the slot number of the primary module only, i.e., the odd-numbered slot.
●
For an intermachine link with redundant Integrated Trunk Modules, enter the slot and bundle number of the primary Integrated Trunk Module only, i.e., the odd-numbered slot.
●
The maximum path delay number that can be entered in a routing table is 7.

To disconnect all channels that originate at node 11, are connected over link 3, and terminate at node 12, enter:
NOD 11 DSC DL 3/N12
To disconnect all channels that originate, terminate, or bypass at node 11 via link 3, enter:
NOD 11 DSC DL 3/A
The DSC DL command can be implemented only at the originator end of a channel unless the /A option is used. Use the DSP CH, DSP MDS0, or DSP DS0 command to determine which end of the channel is the originator.
NOTE:
If a channel is in the process of being connected while the DSC DL command is executed, that channel will NOT be disconnected. After the channel connection is complete, reenter the DSC DL command to disconnect the channel.

Insert and Remove Module (INS, RMV) Commands
The INS command logically inserts a module into a slot. The RMV command logically removes a module from a slot.
NOTE:
The number of Voice Processors, Integrated Trunk Modules,
Channelized Services Processors, Voice Server Modules, and X.50
Server Modules that can be installed in a Mainframe is dependent on their combined total. Refer to the "Maximum Number of Voice Server
Modules per Mainframe" Table in Chapter 2 of the Configuration
Planning Manual for specific number information.
PRECAUTION: Logically removing a Voice Server Module will disconnect all channels supported by that Voice Server Module and place the channels on the retry queue.
Commands:
[NOD xxxx] INS n:ss[-n:ss]...,n:ss[-n:ss] or *
[NOD xxxx] RMV n:ss[-n:ss]...,n:ss[-n:ss]
A module may be physically inserted in a slot, but the LINK/2+ System will not recognize the module unless the INS command is used. Conversely, the RMV command must be used to indicate that a module is no longer inserted in a slot, even when the module has already been physically removed from the slot.
NOTES:
After logically removing a module from a slot using the RMV command, physically remove the module from the slot per the
Replacement Procedures chapter in the LINK/2+ Installation and
Maintenance Manual.
The RMV command does not delete the module database parameters.
See "Delete Slot (DEL) Command" paragraph.
6-96
L2UG
6/30/94
When nodal security is enabled, the received RMV n:ss command is interpreted as a nonglobal gateway command.
To delete a Channelized Services Processor, Voice Processor, or
Integrated Trunk Module once the hardware has been removed, perform the following steps:
•
Disconnect all channels over proprietary bundles (Integrated
Trunk Module only).
•
Disconnect all nonproprietary bundles.
•
Clear redundancy for both the online and redundant pair.
•
Delete the appropriate slot.
At system start-up or after reset of the online Network Module, all modules physically installed will be recognized as logically inserted.
Insert and Delete Route (INS RTE, DEL RTE) Commands
The INS RTE command adds a route (link or bundle and path delay) as an entry into a routing table of a specified node. See the "Define and Clear Routing Table (DEF RTE, CLR RTE)
Commands" paragraph for a general discussion of routing table entries.
Command:
[NOD xxxx] INS RTE xxxx p {ss, n:ss, 1:ss:bdl, or 1:ss:cc} delay where: delay = path delay number, 0 through 7, specifying the minimum number of bypass nodes between the originating and destination nodes.
If the routing table already includes eight entries, this command is rejected.
The path number, p, determines the position of the new route in the list of all available routes to the destination node. In the revised routing table, the new route precedes previously listed routes with the same or higher path number. If the routing table has fewer entries than the specified path number, the new route becomes the last route in the table with the next higher path number.
The DEL RTE command deletes the route with path number p from the routing table to the specified node.
Command:
[NOD xxxx] DEL RTE xxxx p
NOTE:
Before entering a remote command NOD xxxx

Remove Module (RMV) Command
See "Insert and Remove Module (INS, RMV) Commands" paragraph.
Set Alarm Forwarding (SET ALM FWD) Command
The SET ALM FWD command defines which alarm queue the node will use to trigger the transmission of an "I have an Alarm" message to nodes on this node’s remote alarm notification list. See the "Define Alarm Notification List (DEF ALM) Command" paragraph for information on defining the alarm notification list.
Command:
[NOD xxxx] SET ALM FWD {AQ or TAQ} where:
AQ = forwards "I have an Alarm" message when any alarms are logged in the AQ alarm queue
TAQ = forwards "I have an Alarm" message when any alarms are logged in the TAQ alarm queue
The system monitors both the AQ and TAQ alarm queues every 10 minutes. Depending on which queue has been selected by the SET ALM FWD command, if any alarms are present in the queue, the "I have an Alarm" message is generated. Also, if a new alarm occurs, the "I have an Alarm" message is immediately generated.
If the network management system polls alarms using the TAQ alarm queue, select TAQ.
Otherwise, select AQ.
Set Bias Routing for X.50 Subrate Channel (SET BIAS XCH) Command
The SET BIAS XCH command defines the bias route over which an X.50 subrate channel (s) will be connected to a remote node.
Command:
[NOD xxxx] SET BIAS XCH n:ss:cc:sr[-n:ss:cc:sr]/routing where routing is one of the following:
Lss[:cc] = the intermachine link number and bundle number (optional) to which all channels in the specified range of channels will bias
Lss[:cc]/O = only the odd-numbered channels within the specified range of channel numbers will bias to the intermachine link and bundle number (optional) specified in the command
Lss[:cc]/E = only the even-numbered channels within the specified range of channel numbers will bias to the intermachine link and bundle number (optional) specified in the command
OFF = the specified channels will terminate bias routing
6-98
L2UG
7/31/95
OFF/O = only the odd-numbered channels within the specified range of channel numbers will terminate bias routing
OFF/E = only the even-numbered channels within the specified range of channel numbers will terminate bias routing
If the intermachine link specified in the command is out-of-service, then the next intermachine link in the routing table is selected. Every intermachine link in the routing table is attempted before the biased intermachine link is retried. The channel is not placed on the retry queue until every intermachine link in the routing table is tried once.
If the intermachine link selected in the command is not defined or is not listed in the routing table to the destination node, then the LINK/2+ System will attempt connection over the primary, nonbiased route.
Some applications of bias routing include the following:
●
An alternative to the CON DR command: The route defined with the DEF BIAS command remains in the database, while the route defined using the CON DR command will be lost if the channel is subsequently disconnected and reconnected.
●
Channel redundancy: Route two channels with the same destination over two different intermachine links.
●
Route avoidance: Bias route to ensure that less desirable routes are taken only as a last resort.
●
Load sharing: Bias routing can be used to distribute channels over several intermachine links.
Without bias routing, the primary route is always the first one attempted.
NOTE:
The bias routing parameters are defined for originator channels only.
Channels must be disconnected before the SET BIAS XCH command is issued. After the command is issued, the channels must be reconnected for the changes to take effect.
Set Bias Routing for X.50 DS-0 Channel (SET BIAS XS0) Command
The SET BIAS XS0 command defines the bias route (first intermachine link) over which the X.50

OFF/E = only the even-numbered channels within the specified range of channel numbers will terminate bias routing
If the intermachine link specified in the command is out-of-service, then the next intermachine link in the routing table is selected. Every intermachine link in the routing table is attempted before the biased intermachine link is retried. The channel is not placed on the retry queue until every intermachine link in the routing table is tried once.
If the intermachine link selected in the command is not defined or is not listed in the routing table to the destination node, then the LINK/2+ System will attempt connection over the primary, nonbiased route.
Some applications of bias routing include the following:
●
An alternative to the CON DR command: The route defined with the SET BIAS command remains in the database, while the route defined using the CON DR command will be lost if the channel is subsequently disconnected and reconnected.
●
Channel redundancy: Route two X.50 DS-0 channels with the same destination over two different intermachine links.

Channels must be disconnected before the SET BIAS XS0 command is issued. After the command is issued, the channels must be reconnected for the changes to take effect.
Set Bump (SET BMP) Command
The SET BMP command enables or disables end-to-end or point-to-point bumping at a node. The command determines whether an originating channel at a local node, which has an ABM profile authorizing it to be a bumper, will become an active bumper. If bumping is disabled at a local node, a bumper originating at a remote node can still bump a bumpee at the local node.
Command:
[NOD xxxx] SET BMP
{
E or P or D
}
6-100
L2UG
7/31/95
where: E = enables end-to-end bumping only
P = enables point-to-point bumping
D = disables bumping
NOTE:
Since end-to-end bumping is less disruptive to a network than pointto-point bumping, end-to-end bumping will always be attempted first, even when point-to-point bumping is enabled.
Set Bundle Configuration (SET CFG) Command
The SET CFG command defines the bundle configuration for each Integrated Trunk Module and
Channelized Services Processor. Each defined DS-0 channel must be configured as a bundle. For bundle sizes greater than 1, each bundle is defined by specifying the master DS-0 channel and each slave DS-0 channel that is a member of the bundle. For a bundle size of 1, the bundle is defined by specifying the defined DS-0 channel as the master channel and the slave channel. After the Integrated Trunk Module or Channelized Services Processor is configured for bundling, issue all subsequent commands to the master DS-0 channel(s).
NOTE:
To make it easier to remember which DS-0 channel is the master
DS-0 channel, always make the lowest numbered DS-0 channel of the bundle the master DS-0 channel.
Commands:
[NOD xxxx] SET CFG n:ss:cc=cc[-cc]...
[
,cc[-cc]
]
[/A]
[NOD xxxx] SET CFG n:ss:cc/OFF where: cc = specifies each slave DS-0 channel and/or range(s) of DS-0 channels that are members of the bundle
/A = adds specified slave DS-0 channel(s) to an existing bundle
/OFF = clears master channel and all slave DS-0 channels associated with the specified master channel
For example, a Channelized Services Processor in slot 10 of the Control Mainframe, defined for
G.732N framing, contains 31 DS-0 channels. These channels can be configured for bundling as follows:
●
SET CFG 1:10:3=7,11 has a bundle size of 3 with DS-0 channel 3 as the master channel and
DS-0 channels 7 and 11 as the slave channels. The speed of this bundle is 192 kbps. This bundle can be connected to a local or remote Quad Synchronous Processor channel.
●
SET CFG 1:10:1=5,9,13,17,21,25,29 has a bundle size of 8 with DS-0 channel 1 as the master channel and DS-0 channels 5, 9, 13, 17, 21, 25, and 29 as the slave channels. The speed of this bundle is 512 kbps. This bundle can be connected to a local Dual Synchronous Module channel.
●
SET CFG 1:10:2=4,6,8,10,12,14,16,18,20,22,24 has a bun dle size of 12 with DS-0 channel 2 as the master channel and DS-0 channels 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 as the slave channels. The speed of this bundle is 768 kbps. This bundle can be connected to a remote
Channelized Services Processor bundle.

Processor.
●
SET CFG 1:10:30=30 has a bundle size of 1 with DS-0 channel 30 as the master channel. The speed of this channel is 64 kbps. This bundle can be connected to a local or remote Voice
Processor.
●
SET CFG 1:10:31=31 has a bundle size of 1 with DS-0 channel 31 as the master channel. The speed of this channel is 64 kbps. This bundle can be connected to a local or remote Subrate
Channel Processor.
●
SET CFG 1:10:3/OFF clears master channel 3 and all slave DS-0 channels, channels 7 and 11, associated with master DS-0 channel 3.
●
SET CFG 1:10:2 = 16/A adds DS-0 channel 16 as a member of the bundle with master channel
1:10:2.
NOTES:
If the Integrated Trunk Module or Channelized Services Processor is defined for G.732S framing, DS-0 channel 16 cannot be used.
Channels must be disconnected before the SET CFG command is issued. After the command is issued, the channels must be reconnected for the changes to take effect.

Command:
[NOD xxxx] SET CSW QS
The SET CSW SS command allows the LINK/2+ System to qualify and start locking to an alternate clock source within 30 seconds.
Command:
[NOD xxxx] SET CSW SS
Use the DSP ST CLK command to display the current clock switching time interval.
Set Contention (SET CTN) Command
The SET CTN command enables or disables dynamic bandwidth allocation on a call demand basis to Voice Processor DS-0 channels programmed for contention. Contending DS-0 channels are monitored for off-hook and are allocated bandwidth, if available, and placed in the connected state. The allocated bandwidth is returned to the bandwidth pool when the call originator goes onhook. The command can also be used to force connections between DS-0 contention channels that are not busied out.
Command:
[NOD xxxx] SET CTN
{
E or D or C
}
where: E = enables DS-0 contention
D = disables DS-0 contention
C = connects DS-0 contention channels that are not busied out. The connect request is issued from the lower node.
Set Backup Link (SET DL BCK) Command
The SET DL BCK command defines or cancels the proprietary bundle on an Integrated Trunk

If the channel is connected over its bias route but the actual path delay is greater than the shortest path delay defined in the routing table
In addition, channels that were connected in override will be groomed.
If a channel is a local connection channel, contention channel, or directly connected channel, the channel will not be groomed.
A channel will be reconnected when the grooming reconnect time is reached.
For backup and expansion bundles with grooming enabled, the bundle connection will terminate at grooming disconnect time if and only if the intermachine link being backed up has come back in service.
Set and Clear Remote Node Gateway (SET GWY, CLR GWY) Commands
The SET GWY command designates the specified remote node supervisory port or supervisory computer port as a gateway. The CLR GWY command clears the gateway status. Gateway status is initially determined by Network Module DIP switch but can be changed by the SET GWY or
CLR GWY command.
Commands:
NOD xxxx SET GWY
{

Set Phone Numbers (SET PHN BCK, SET PHN XDL) Commands
The SET PHN BCK and SET PHN XDL commands enter the user’s ISDN or Switched 56K phone numbers into directories for the specified Interlink Module or Integrated Trunk Module.
The directories are used for dial-up services. The SET PHN BCK command establishes the directory of phone numbers used for the dial-up service link backup feature used by the Integrated
Trunk Module and Interlink Module. The SET PHN XDL command establishes the directory of phone numbers used for the dial-up service link expansion and dial link features used only by the
Integrated Trunk Module.
Commands:
[NOD xxxx] SET PHN BCK {1:ss:cc=phn[/D or /I][/H0] or 1:ss:cc[/C][/H0] or 1:ss:*/C}
[NOD xxxx] SET PHN XDL {1:ss:cc=phn[/D or /I][/H0] or 1:ss:cc[/C][/H0] or 1:ss:*/C} where: phn = ISDN or Switched 56K phone number up to 16 characters (0 through 9, *, #, :,
-). The hyphen (-) is used for clarity only. For ISDN applications, the colon (:) can be used only once to indicate that the following characters are a network sub-party address. The asterisk (*) and pound sign (#) are used with ISDN applications only. ISDN applications may use up to 20 characters.
/D = Domestic (default)
/I = International
/C = Clears phone number(s)
/H0 = H0-channel
NOTE:
The * can be used to specify all channels of a module only when the
/C option is used.
For example, to define the phone number 1-201-555-6000 as the link backup phone number for channel 12, enter:
SET PHN BCK 1:5:12=1-201-555-6000
Use the DSP PHN BCK or DSP PHN XDL command to display all the phone numbers listed for the specified directory.

Set and Clear Redundant Module (SET RDN, CLR RDN) Commands
The SET RDN command sets the redundancy logic between a pair of associated Interlink
Modules, Integrated Trunk Modules, Channelized Services Processors, D-Channel Modules, or
Voice Processors. The SET RDN command also copies intermachine link parameter values from one Interlink Module to the other, or DS-1/DS-0 parameter values from one Voice Processor,
Integrated Trunk Module, or Channelized Services Processor to the other. The CLR RDN command clears the redundancy logic between the pair, but does not affect parameter values.
Either command resets both modules of a redundant pair.
Commands:
[NOD xxxx] SET RDN [n:]ss
[NOD xxxx] CLR RDN [n:]ss
Redundant operation is possible only if the two modules are of the same type and are inserted into adjacent slots with the left-most module occupying an odd-numbered slot. The ss specified in the command is the slot number of the module containing the desired parameter values.
NOTE:
If a remote SET RDN or CLR RDN command is sen t to a node that targets the only datalink (i.e. route) back to the issuing node the prompt character of the supervisory port will not return to the display.
Enter a Control-C character to terminate the command and return the prompt character to the display. The SET RDN command does not copy the LFM SLOT and LFM BNDL parameter fields of an Interlink
Module database.
6-112
L2UG
7/31/95
To initially configure a redundant pair of modules, perform the following:
●
Ensure that the two modules are adjacent to each other and that the left-most module is in an odd-numbered slot.
●
Using the appropriate command, define the parameter values for one of the modules of the redundant pair.
●
Issue the SET RDN command, specifying the value for ss as the slot number of the module containing the desired parameter values.
For example, to ensure that the redundant module in slot 4 has the same parameter values as the module in slot 3, enter:
SET RDN 1:3 Sets the redundancy logic and copies the parameter values of the module in slot 3 to the module in slot 4. Thereafter, if the online module fails, the redundant module will take control to maintain service.
NOTE:
It is recommended that channels on Voice Processors or Channelized
Services Processors be disconnected before issuing a SET RDN command. In addition, if Voice Processors or Channelized Services
Processors have channels in queue waiting to be connected when the
SET RDN command is issued, the command is aborted and the message "CHANNEL(S) QUEUED, CMD ABORTED" is displayed.
The operator should wait for the connections to be completed before proceeding.
The CLR RDN command clears the redundancy logic but does not affect the parameter values in either module. If the command is issued to either of the modules in a redundant pair that have been properly configured for redundant operation, the online module will continue normal operation but, if that module fails, the redundant module will not take control.
For example:
CLR RDN 1:3 or
CLR RDN 1:4
Clears the redundancy logic between the modules in slots 3 and 4. Thereafter, if the online module fails, the redundant module will not take control to maintain service.
Set System Connect Retry Timer (SET RET) Command
See "Define System Connect Retry Timer (DEF RET) Command" paragraph.

6-113
Set and Clear Nodal Security (SET SEC, CLR SEC) Commands
The SET SEC command enables nodal security and restricts a node from accepting global gateway commands. When nodal security is enabled, all global gateway commands are interpreted by the node as nonglobal commands and are accepted only if both:
●
The supervisory port or supervisory computer port originating the command is designated a gateway.
●
The node number of the node originating the command is on the alarm notification list of the node receiving the command.
The CLR SEC command disables nodal security and allows the node to accept global gateway commands from any gateway node.
Commands:
[NOD xxxx] SET SEC
[NOD xxxx] CLR SEC
Use the DSP SY command to determine if nodal security is enabled or disabled.
Set Link Framing Module Time Slots (SET TSA and SET TSB)
Commands
The SET TSA and SET TSB commands establish the active time slots on the Link Framing
Module (Models LFM.10, LFM.11, and LFM.12) and determine the time slots that make up bundles A and B on the connected trunk(s).
The number of assigned time slots in bundles A and B must match the speeds assigned with the
DEF LFM command. If the DEF LFM command sets the Link Framing Module to two-to-one mode, the time slots for bundles A and B cannot overlap.
Commands:
[NOD xxxx] SET TSA n:ss[-n:ss]...
[
,n:ss[-n:ss]
]
=cc[-cc]...
[
,cc[-cc]
]
[NOD xxxx] SET TSA n:ss[-n:ss]...

=cc[-cc]...
[
,cc[-cc]
]
[NOD xxxx] SET TSB n:ss[-n:ss]...
[
,n:ss[-n:ss]
]
/OFF where: /OFF = clears all time slot assignments for the bundle
For example, to set time slots 1 through 12 and 13 through 24 as active for the local LFM.12
module in slot 9 of nest 1, enter:
SET TSA 1:9=1-12
SET TSB 1:9=13-24
6-114
L2UG
7/31/95
NOTE:
The SET TSA and SET TSB commands enter the new active time slots parameters to take effect, the Link Framing Module(s) must be reset.
Set Voice Server Module (SET VSM) Command
The SET VSM command defines the specified module(s) as a Voice Server Module.
Command:
[NOD xxxx] SET VSM n:ss[-n:ss]...
[
,n:ss[-n:ss]

DIAGNOSTIC COMMANDS
Supervisory port diagnostic commands are described in the following paragraphs. Commands are in alphabetical order by command mnemonic. Related commands are discussed together.
Busy Out DS-0 (BSY) Command
The BSY command places specified DS-0 channel(s) in the busy state. The busy state is also called a remote equipment busy out (RE). When a DSP ST DS0 command is issued, the loop status of these channels will be displayed as RE type.
NOTE:
To place V-channel(s) on a Voice Server Module in the busy state, refer to the RST CH command in this chapter.
Issuing the LP DS0 EQ command also places the remote end of specified DS-0 channel(s) in the busy state. The CLR LCL command clears specified channel(s) from the busy state.
Command:
[NOD xxxx] BSY
{
* or n:ss:cc[-n:ss:cc]...
[
,n:ss:cc[-n:ss:cc]
]}[{
/mmm or /P
}]
where: /mmm = number of minutes (1-240) after which busy out is cleared automatically
(default is 2 minutes)
/P = permanent; busy out will not be cleared automatically
Center Phasor (CEN PHS) Command
The CEN PHS command optimizes the phasor(s) of the specified Voice Processor DS-0 channel(s) to reduce timing errors.
Command:
[NOD xxxx] CEN PHS
{

Clear Local DS-0 (CLR LCL) Command
The CLR LCL command clears channel(s) from the busy state (RE loopback state) at the local end of specified DS-0 channel(s) or bundled channels of specified master.
As long as any DS-0 channels that have been placed in loopback remain connected, the CLR
DS0 command should be used to clear loopback at both ends of the DS-0 channel(s) in one operation. However, if the local Voice Processor, Integrated Trunk Module, or Channelized
Services Processor is reset, the loopback will be cleared at the local end of the DS-0 channel(s), but the remote end will remain in a busy out state. In this situation, use CLR LCL at the remote node or NOD xxxx CLR LCL at the local node to clear the remote DS-0 busy out state.

LD = local modem local digital loopback for data channels; bidirectional channel controller loopback for Quad Voice Module and Enhanced Voice Module channels only
LA = local modem local analog loopback for data channels; codec loopback for
Quad Voice Module and Enhanced Voice Module channels only
RA = remote modem remote analog loopback
RD = remote modem remote digital loopback
VS = used with Quad Voice Module channels serviced by a Voice Server Module.
Places associated V-channel in bidirectional loopback
NOTE: /P is a required modifier that is used with VS loopback only.
Optional modifiers /I and /O are used with asymmetrical channels only:
/I = runs loopback using input speed. Default loopback speed is /I.
/O = runs loopback using output speed
7-12
L2UG
8/30/94
L2UG
6/30/97
Speed is an optional modifier used with Isochronous Communication Module and Dual
Isochronous Module channels only to alter the nominal test speeds of isochronous communication loopback testing:
/F = force output frequency faster than nominal communication speed
/S = force output frequency slower than nominal communication speed
/R = force output frequency equal to nominal communication speed
If speed modifier is not entered, default is a normal loopback with phasor timing.
NOTES:
No warning is given if VS loopback is specified and channel is not being processed by a Voice Server Module.
LP RB CH command is not used with Quad Synchronous Processors.
Use LP LS CH and LP LP CH commands for Quad Synchronous
Processor bidirectional loopbacks.
If a Quad Synchronous Module channel is disconnected while still in loopback, the channel status will be shown as in loopback (not as disconnected) when a DSP ST CH command is issued. To avoid this, clear the loopback before disconnecting the channel.
PRECAUTION: When more than one channel on a Quad Asynchronous
Module is set to a speed of 19.2 kbps and one of the 19.2
kbps channels is placed in remote loopback (NOD xxxx
LP loopback CH), if one or more other 19.2 kbps channels is connected, the channel in loopback will lose synchronization.
This problem does not occur when an external loopback plug is used at the remote node.
To test local I/O module channels with the local test generator and test detector, use the LP CH command with the TST L command.
To test remote I/O module channels that connect to local I/O module channels using the local test generator and test detector with the TST R command:
●
Loop the remote channel toward the local channel using the NOD xxxx LP CH command.
●
Loop the local I/O channel toward the remote channel using the LP CH command.
●
Use the TST R command to initiate a complete or partial test message that is looped first by the local channel and passed across an intermachine link to the remote channel. The remote channel loops the test message back across an intermachine link to the local node where the message is received by the test detector.
NOTE:
Local and remote channel loopback tests, when used on data channels, require that the tail circuit modems accept test signals
(CCITT circuits 140 and 141).

Bidirectional Bus Loopbacks
The LP LB CH and LP RB CH commands loop the circuit bidirectionally at the local I/O module channel interface, Figure 7-2A. The internal bus loop can be tested using the internal test generator and test detector. The external bus loop can be tested using an external pattern generator or a terminal.
For QVC Voice Module channels only, the external bus loop which passes through the E & M
Interface Module can be tested using a transmission impairment measurement set (TIMS), Figure
7-2B.
Bidirectional Loopbacks
The LP LS CH and LP LP CH commands place the specified Quad Synchronous Processor channels in loopback, Figures 7-3 and 7-4. The LP LS CH command can also be used with
Isochronous Communication Module channels.
Quad Synchronous Processor channels can be synchronous I/O channels, Switched 56K Service channels, or broadcast/polled channels.
Isochronous Communication Module channels can be plesiochronous data at rates of up to 1.544
Mbps or isochronous data at rates of up to 512 kbps.
NOTES:
An LS loopback for a DTE1 channel will result in a loop timed interface. An LP loopback for a DTE1 channel will result in the transmit clock being driven from the system timing source. An LS loopback for a DTE2 channel is not supported unless both the receive and transmit clocks are phase aligned, but the LP loopback will always work regardless of clocking configuration.
When a Quad Synchronous Processor channel is in LP loopback, the
DSP FN command will show remote input functions in the "O=" part of the display. See the Display Commands chapter for a description of the DSP FN command.
When a Quad Synchronous Processor DTE2 port is programmed for a bus/serial bidirectional loopback, the local user (external DTE2) input clock clocks data both into and out of the ports. Additionally, remote data to and from the intermachine link is clocked from the output phasor into the input phasor using the local user DTE2 output clock.
When a Quad Synchronous Processor DTE2 port is programmed for a parallel bidirectional loopback, the following operation is supported:
●
The local user (external DTE2) input clock is used to clock local data into the local port and the local user (external DTE2) output clock is used to clock local data from the local port.

No clock but rather the intermachine link’s scan cycle is used to clock data both from the local intermachine link to the local port and from the local port to the local intermachine link, over the local bus interface.
When an Isochronous Communication Module DTE2 port is programmed for a bus/serial bidirectional loopback, the local user
(external DTE2) input clock clocks data both into and out of the ports. Additionally, remote data to and from the Isochronous
Communication Module is clocked from the output phasor into the input buffer using the output phasor’s derived clock.
When an Isochronous Communication Module DTE2 port is programmed for a parallel bidirectional loopback, the following operation is supported:
●
●
The local user (external DTE2) input clock is used to clock local data into the local port, and the local user (external DTE2) output clock is used to clock local data from the local port.
No clock but rather the intermachine link scan cycle is used to clock data both from the local intermachine link to the local port and from the local port to the local intermachine link, over the local bus interface.
Local Digital Channel Loopback
For data channels, the LP LD CH command directs an external modem to loop the circuit at the digital interface of the local modem, Figure 7-5A. If the external modem does not accept the test control signals, use a loopback plug, Figure 7-6. For Quad Voice Module or Enhanced Voice
Module channels only, the LP LD CH command loops the circuit bidirectionally at the channel controller, Figure 7-5B. The external channel controller loop can be tested using an external
TIMS. The internal loop can be tested using the internal test generator and detector or a remote
TIMS. The Enhanced Voice Module is equipped with front panel test jacks which may be used to connect the TIMS and conduct loopback testing.
Local Analog Channel Loopback
For data channels, the LP LA CH command directs an external modem to loop the circuit at the analog interface of the local modem, Figure 7-7A (CCITT circuit 141 output on pin 16 of I/O channel connector).
For Quad Voice Module or Enhanced Voice Module channels, the LP LA CH command loops the circuit at the analog interface of the codec, Figure 7-7B. The codec loop can be tested using an external TIMS at the opposite end of the channel connection.
For QSP.2 Quad Synchronous Processor data channels connected to a Link Framing Module, the
LP LA CH command causes the Link Framing Module to enter a remote digital loop via the
QSP-LFM cable.
NOTE:
For the Isochronous Communication Module, whenever a local analog (LA) or local digital (LD) loopback is selected, the
Isochronous Communication Module will always execute a local analog loopback.

Bidirectional V-Channel Loopback
The LP VS CH command is issued to a Quad Voice Module channel serviced by a Voice Server
Module. This command places the associated V-channel on the Voice Server Module in bidirectional loopback. The V-channel PCM phasor data is looped back towards the Quad Voice
Module and the V-channel processed phasor data is looped back towards the Interlink Module or
Integrated Trunk Module, Figure 7-10.
To test the PCM phasor side (towards the Quad Voice Module in Figure 7-10) of the local Voice
Server Module V-channel, use an external TIMS connected to the associated local Quad Voice
Module port.
To test the processed phasor side (towards the Integrated Trunk or Interlink Module in Figure
7-10) of the local Voice Server Module V-channel, use an external TIMS connected to the associated remote Quad Voice Module port at the other end of the channel connection. The test signal is sent from the remote node over the intermachine link to the local Voice Server Module and then looped back across the intermachine link to the remote TIMS.

(LP DL, CLR DL) Commands
The LP DL command places intermachine link(s) associated with Interlink Module(s) specified by slot ss in loopback. An optional loopback time of between 1 and 15 minutes is permitted with the default time being 2 minutes. Optional permanent loopbacks are allowed locally.
The CLR DL command clears specified intermachine link(s) from loopback, restoring intermachine link(s) to normal operation.

LD = local line driver local digital loopback
LA = local line driver local analog loopback
RA = remote line driver remote analog loopback
RD = remote line driver remote digital loopback

and where: ss = Interlink Module slot number
/mm = number of minutes (1-15) after which loopback is cleared automatically
(default is 2 minutes)
/P = permanent; loopback will not be cleared automatically. Cannot be used for loopbacks issued to a remote node.
Optional modifiers /R and /T are used with asymmetrical links only:
/R = runs loopback using received speed. Default loopback speed is /R.
/T = runs loopback using transmit speed
[NOD xxxx] CLR DL
{

where: ss = Interlink Module slot number
Executing the LP DL command results in an immediate display of the loopback status. An example of placing the Interlink Module in slot 7 into local bus loopback for 9 minutes is:
Command: LP LB DL 7/09
Response: LINK 1:07
LOOP= LB TIME: 09
If the Interlink Module fails to go into loopback, one of the following error messages will be displayed:
●
TIMED OUT BEFORE LOOPBACK
●
MUST NOT LOOPBACK SYSTEM CLOCK
●
MUST NOT INITIATE RB LOOPBACK IF TXCLOCK=RCV
Intermachine Link Loopback Tests
To perform an intermachine link loopback test, a channel must be connected across the intermachine link in loopback using the CON DR programming command.
●
The intermachine link in loopback must be in the routing table at the destination node of the specified channel.
●
The path number specified in the CON DR command must establish a route for the specified channel via the intermachine link in loopback in the command.
To test the intermachine link loopbacks with the internal test generator, use the TST R command with a local I/O module channel loopback. The TST R command initiates a test message that is looped by an I/O module channel to the Interlink Module. The intermachine link loopback will loop the test message back to the local test detector.
To test the intermachine link loopback with external test equipment, connect an external pattern generator to the channel that is connected across the intermachine link in loopback. The test signal will enter the LINK/2+ System through the channel and will be looped back to the test equipment by the intermachine link loopback.

NOTE:
Any intermachine link that is providing timing to a node cannot be looped toward that node. Intermachine link loopback commands will be rejected by the LINK/2+ System and result in the error message:
MUST NOT LOOPBACK SYSTEM CLOCK. An exception is an intermachine link defined on the clock fallback list as a DRI clock source. The intermachine link would still qualify as an acceptable nodal timing source if either a remote bus or an external loopback is performed.
Local Bus Intermachine Link Loopbacks
The LP LB DL command loops the circuit at the Interlink Module bus, Figure 7-11.
Local Digital Intermachine Link Loopback
The LP LD DL command loops the circuit at the bipolar encoder/decoder of the local line driver
(for example, Digital Termination Module or Link Framing Module), Figure 7-12, or directs an external modem to loop the local digital interface, Figure 7-13A. If the modem does not accept loopback commands, use a loopback plug on the Interlink Module, Figure 7-15A.
Local Analog Intermachine Link Loopback
The LP LA DL command loops the circuit at the bipolar encoder/decoder of the local line driver,
Figure 7-12, directs an external modem to loopback at the local analog interface, Figure 7-13B, or loops the circuit at the buffer of the local LFM.14 Link Framing Module, Figure 7-14.
Loopback plugs can be used on Digital Termination Modules and Link Framing Modules, Figure
7-15B.
NOTE:
On Digital Termination Modules and Link Framing Modules, the LP
LD DL and LP LA DL commands loop the intermachine link at the same location.
PRECAUTION: The LP LA DL command must not be used on an intermachine link with an LFM.3 Link Framing Module that uses receive (RCV) timing if the Network Module is not type C or D. With any other Network Module, the required clocking cannot be supplied for this loop command under these conditions.

Loop DS-0 Channel and Clear DS-0 Channel Loop
(LP DS0, CLR DS0) Commands
The LP DS0 command places specified DS-0 channel(s) or bundled channels of specified master in loopback. The CLR DS0 command clears specified DS-0 channel(s) or any associated Dchannel(s) or V-channel(s) from loopback, restoring channels to normal operation. This command does not center the phasor. Use the CEN PHS command to center phasor(s) of the specified DS-0 channel(s). When the CLR DS0 command is issued to a member of a bundle, all associated members of the bundle are cleared of DS-0 loopback.
AB bit signaling is ignored and timers are reset for all bandwidth contention DS-0 channels in loopback. Contending channels will not automatically connect and disconnect.
Commands:
[NOD xxxx] LP DS0 loopback
{
* or n:ss:cc[-n:ss:cc]...
[
,n:ss:cc[-n:ss:cc]

where loopback is one of the following:
EQ = channel phasor loopback toward the DS-1 (or E-1) trunk, that is, toward the external equipment
LI = channel phasor loopback toward an Interlink Module, I/O module, Integrated
Trunk Module, Voice Processor, or Channelized Services Processor via the system bus, that is, toward the LINK network
7-40
L2UG
6/30/94
L2UG

BI = channel phasor bidirectional loopback
RA = remote analog loopback of remote line driver of the remote Interlink Module
RB = remote Integrated Trunk Module bus loopback
RD = remote digital loopback of remote line driver of the remote Interlink Module
VS = used with channels serviced by a Voice Server Module. Places associated Vchannel in bidirectional loopback and where:
/mmm = number of minutes (1-240) after which loopback is cleared automatically
(default is 2 minutes)
/P = permanent; loopback will not be cleared automatically (option not valid for remote Integrated Trunk Module proprietary bundle or Interlink Module)
NOTES:
The /mmm option does not apply to VS loopbacks. The /P option, however, is a required modifier for VS loopbacks.
No warning is provided if VS loopback is specified and channel is not processed by a Voice Server Module.
The remote LP DS0 EQ command NOD xxxx LP DS0 EQ cannot be used for remote connected Voice Processor, Integrated Trunk
Module, and Channelized Services Processor DS-0 channels or bundles.
After the LP DS0 command is entered, the supervisory port displays the loopback status of the
DS-0 channels, Figure 7-20.
To test a local DS-0 channel that connects locally to an I/O module using the local test generator and test detector:
NOTE:
The internal test generator and detector cannot be used with the
Voice Server Module. For those loopback tests, use external test equipment.
●
Loop the I/O module channel toward the DS-0 channel using the LP CH command.
●
Loop the DS-0 channel toward the I/O module channel using the LP DS0 command.
●
Use the TST R command to initiate a test message that is looped first by the I/O module and passed to the Voice Processor or Channelized Services Processor. The Voice Processor or
Channelized Services Processor loops the test message at the DS-0 channel phasor back to test detector.
To test a local DS-0 channel that connects locally to another DS-0 channel using the tone generator on the Voice Processor or Channelized Services Processor:
●
Loop the DS-0 channel at one of the Voice Processors or Channelized Services Processors using the LP DS0 command.
●
Use the SET TON command on the other Voice Processor or Channelized Services Processor to initiate a test tone toward the looped DS-0 channel. The looped DS-0 channel returns the test tone to the unlooped DS-0 channel.

●
Use external test equipment to monitor the tone received by the unlooped DS-0 channel.
To test a local DS-0 channel that connects across an intermachine link to a remote I/O module using the remote test generator and test detector:
●
Loop the I/O module channel toward the local node using the NOD xxxx LP CH command.
●
Loop the DS-0 channel toward the remote node using the LP DS0 command.
●
Use the NOD xxxx TST R command to initiate a test message that is looped first by the remote I/O module and passed across an intermachine link to the local DS-0 channel in loopback. The DS-0 channel returns the test message to the remote node via an intermachine link where the message is received by the remote test detector.
To test a local DS-0 channel that connects across an intermachine link to a remote DS-0 channel using the tone generator on the remote Voice Processor or Channelized Services Processor:
●
Loop the local DS-0 channel toward the remote channel using the LP DS0 command.
●
Use the NOD xxxx SET TON command to initiate a test tone that passes across the intermachine link to the local DS-0 channel in loopback.
●
Use external test equipment at the remote node to monitor the looped tone.

L2UG
8/30/94
NOTE:
If the channel is an ILP contention channel, the channel must be disconnected, the connect type reprogrammed at both ends as originator/terminator, and reconnected before proceeding with the above steps.
Equipment Loopback
The LP DS0 EQ command loops the specified DS-0 channel circuit toward the DS-1 (or E-1) trunk (that is, toward the local equipment) at the phasor, Figure 7-21. The equipment loop can be tested by using the SET TON command or an external tone generator and an external tone monitor.
Provided that channel connections exist, executing the LP DS0 EQ command automatically issues the BSY command to busy out the remote end of the specified DS-0 channel(s). The remote DS-0 channel(s) will become busied out before the equipment loopback is established and will remain busied out for 1 minute after the loopback is removed.
If the BSY command cannot reach the remote node for any reason, such that the command hangs up the system, issue Control C characters from the keyboard until the supervisory port prompt
(Nxxxx>) reappears.
AB bit signaling is ignored and timers are reset for all bandwidth contention DS-0 channels in loopback. Contending channels will not automatically connect and disconnect.

The LP DS1 EQ command, Figure 7-28, loops the incoming DS-1 (or E-1) signal toward the trunk at the DS-1 (or E-1) interface, Figure 7-29. All DS-0 channels on the specified trunk must be disconnected before this loopback command is entered, and reconnected following the loopback test.
For Voice Processors and Channelized Services Processors, if any affected DS-0 channels are connected when the LP DS1 EQ command is issued, the command will be rejected and the message "CHANNELS ARE CONNECTED, CMD ABORTED" will be displayed. Also, if a command is issued to connect a DS-0 channel while the equipment loopback is in effect, the command will be rejected. A subsequent display of DS-0 channel connections will show a DISC
ALARM indication.

Loop LFM and Clear LFM (LP LFM, CLR LFM) Commands
The LP LFM command places in loopback all intermachine links associated with the LFM.14
Link Framing Module specified by slot n:ss. An optional loopback time of between 1 and 15 minutes is permitted with the default time being 2 minutes. Optional permanent loopbacks are allowed locally.
The CLR LFM command clears the line driver (high speed port) of the specified LFM.14 Link
Framing Module from loopback, restoring all ILC.2 Interlink Modules and/or all ILQ.1
Integrated Trunk Modules associated with the LFM.14 Link Framing Module to normal operation.
Commands:
[NOD xxxx] LP LFM loopback
{
* or n:ss[-n:ss]...
[
,n:ss[-n:ss]
]}[{
/mm or /P
}]
where loopback is one of the following:
LK = loopback at line driver toward Link Framing Module
LLB = loopback at line driver toward the JT-2 trunk (ILQ.1 Integrated Trunk
Module only) and where:
n:ss = slot location of LFM.14 Link Framing Module
/mm = number of minutes (1-15) after which loopback is cleared automatically
(default is 2 minutes)
/P = permanent; loopback will not be cleared automatically. Cannot be used for loopbacks issued to a remote node.
[NOD xxxx] CLR LFM
{
* or n:ss[-n:ss]...
[
,n:ss[-n:ss]
]}
where:
n:ss = slot location of LFM.14 Link Framing Module
The LP LFM LK command loops the outgoing JT-2 signal towards the LINK/2+ System at the line driver, Figure 7-32A. The local trunk acts like an open circuit while the loopback is in effect.
The equipment connected to the trunk may detect an alarm condition. All intermachine links supported by the LFM.14 Link Framing Module will be placed in loopback when this command is entered.
The LP LFM LLB command loops the incoming JT-2 signal toward the trunk at the LFM.14
Module line driver, Figure 7-32B. All intermachine links supported by the LFM.14 Link
Framing Module will be placed in loopback when this command is entered.

Loop Network Interface (LP NI) Command
The LP NI command places the DS-1 (or E-1) trunk on specified Voice Processor(s), Integrated
Trunk Module(s), or Channelized Services Processor(s) in loopback at the line driver, that is,
Bipolar Interface Module, Digital Termination Module, or Link Framing Module.
The CLR DS1 command clears the DS-1 (or E-1) trunk from loopback at the line driver. See
"Loop DS-1/E-1 Trunk and Clear Trunk Loop (LP DS1, CLR DS1) Commands" paragraph.
Command:
[NOD xxxx] LP NI loopback
{
* or n:ss[-n:ss]...
[
,n:ss[-n:ss]
]}[{
/mmm or /P
}]
where loopback is one of the following:
LK = loopback at line driver toward the Voice Processor, Integrated Trunk Module, or Channelized Services Processor
LLB = loopback at line driver toward the DS-1 (or E-1) trunk and where:
/mmm = number of minutes (1-240) after which loopback is cleared automatically
(default is 2 minutes)
/P = permanent; loopback will not be cleared automatically
For Voice Processor, Integrated Trunk Module, or Channelized Services Processor, the LP NI
LK command loops the outgoing DS-1 (or E-1) signal toward the Voice Processor, Integrated
Trunk Module, or Channelized Services Processor at the bipolar encoder/decoder on the line driver, Figure 7-33. The local trunk acts like an open circuit at the line driver while the loopback is in effect. The equipment connected to the trunk may detect an alarm condition. If the line driver does not accept LINK/2+ System loopback commands, use a loopback plug, Figure
7-15D, on the Voice Processor, Integrated Trunk Module, or Channelized Services Processor.
For LFM.14 Link Framing Module, the LP NI LK command loops the outgoing signal toward the ILQ.1 Integrated Trunk Module at the buffer of the local LFM.14 Link Framing Module,
Figure 7-34.
For Voice Processor, Integrated Trunk Module, or Channelized Services Processor, the LP NI
LLB command loops the incoming DS-1 (or E-1) signal toward the trunk at the bipolar encoder/decoder of the line driver, Figure 7-35.
PRECAUTION: For Integrated Trunk Modules, proprietary bundle channels will not automatically reconnect after the LP NI
LLB loopback is cleared. All DS-0 channels on the specified trunk must be disconnected before this loopback command is entered and must be reconnected following the loopback test.
For LFM.14 Link Framing Module, the LP NI LLB command loops the incoming signal toward the JT-2 trunk at the buffer of the local LFM.14 Link Framing Module, Figure 7-36.
AB bit signaling is ignored and timers are reset for all bandwidth contention DS-0 channels in loopback. Contending channels will not automatically connect and disconnect.

NOTE:
After issuing a remote RST command to an online Network Module, online Integrated Trunk Module, or online Interlink Module, enter a
Control C character to display the supervisory port prompt.
Resetting a module initiates a hardware and firmware self-test (hardware only on Quad
Synchronous Processor) and reinitializes the module. Use the DSP ERR command to display self-test results.
In addition to the self-test:
●
Reset to an online Network Module:
All modules in the LINK/2+ System are reset.
If online Network Module is part of a redundant pair, the offline Network Module becomes the online Network Module, unless an error is detected in the offline Network
Module.
●
Reset to an offline Network Module of a redundant pair:
Offline Network Module performs self-test.
Parameters from the online Network Module are loaded into the database of the offline
Network Module.
●
Reset to an online Interlink Module in a nonredundant configuration causes intermachine link parameters to be loaded.
●
Reset to an online Interlink Module of a redundant pair:
Offline Interlink Module is switched online.
Original online Interlink Module performs self-test.
If both Interlink Modules are connected to a Digital Termination Module, both the
Interlink Module and the associated driver unit on the Digital Termination Module are switched as a pair.
●
Reset to an online Voice Processor in a nonredundant configuration loads all DS-1 (or E-1) and DS-0 parameters.
●
Reset to an online Voice Processor of a redundant pair:
Offline Voice Processor loads all DS-1 (or E-1) and DS-0 parameters and is switched online.
Original online Voice Processor is switched offline and performs self-test.
If the Voice Processors are connected to Bipolar Interface Modules or Digital Termination
Units, each Voice Processor and its associated Bipolar Interface Module or Digital
Termination Unit are switched in unison.
●
Reset to an offline Voice Processor of a redundant pair downloads all DS-1 (or E-1) and DS-0 parameters from the online Voice Processor and performs a self-test.
L2UG
6/30/94
●
Reset to a Channelized Services Processor operates the same as reset to a Voice Processor.
●
Reset to an Integrated Trunk Module operates the same as reset to a Voice Processor:
All proprietary bundles are reinitialized.
Dial-up connections must be manually reestablished.
●
Reset to an online Bypass Module:
Channel connections in Bypass Module are cleared, and Network Module reestablishes all bypass channel connections that existed prior to the reset.
If online Bypass Module is part of a redundant pair, the offline module becomes the online module. The Network Module reestablishes all bypass channel connections that existed prior to the reset.
●
Reset to an offline Bypass Module causes a self-test of the offline Bypass Module.
●
Reset to a primary X.50 Server Module that is currently online causes the next available redundant X.50 Server Module that is in the next highest numbered slot to take over.
NOTE:
A primary X.50 Server Module in the Control Mainframe requires the supporting redundant X.50 Server Module(s) be located in the
Control Mainframe as well.
During this switch over, the X.50 channels and X.50 subrate channels remain fully connected.
If there is no redundant X.50 Server Module available, the primary module will disconnect the channels, perform a self-test and then (if the self-test is successful) reconnect the channels.
●
Reset to a redundant X.50 Server Module that is currently online causes the original primary module to take over providing the primary module has recovered from its failure state.
Otherwise, the next available redundant module will take over.
●
Reset to a redundant X.50 Server Module that is currently offline causes the module to perform a self-test and then return to the redundant offline state.
●
Reset to a Quad Synchronous Processor reinitializes module hardware and updates channel parameters.
Reset Bundle (RST BDL) Command
The RST BDL command causes a disconnect and then a reconnect on the specified Integrated
Trunk Module bundle. When the command is issued to a proprietary bundle, all channels in the bundle are disconnected and may be assigned to alternate routes. In addition, ARQ/BER testing is restarted, and Alarms 6 and 7 are generated. If the bundle parameters were changed prior to issuing this command, the new bundle parameters take effect upon reconnect. If the specified bundle is a dial link type, the bundle realigns after all DS-0s are reconnected.
When issued to a nonproprietary bundle, the command disconnects all DS-0s in the bundle, causing an out-of-service condition and possibly a signal disruption, and then attempts to
L2UG
6/30/94
7-65
reconnect all DS-0s if bandwidth is available. If the bundle parameters were changed prior to issuing this command, the new bundle parameters take effect upon reconnect.
Command:
[NOD xxxx] RST BDL 1:ss:cc
For example, to reset a bundle with master DS-0 2 originating at node 61 on the Integrated Trunk
Module in slot 12, enter:
NOD 61 RST BDL 1:12:2
Reset V-Channel (RST CH) Command
The RST CH command resets the specified V-channel (s) on a Voice Server Module without affecting the channel connections. The optional /B qualifier allows the user to block out one or more V-channels, making them unavailable. Channels that are blocked out will be skipped by the
Network Module when the Voice Server Module channels are scanned for possible connections.
When the DSP ST VCH command is issued, the blocked channels will show a BUSY status.
Re-issuing the RST CH command, without the /B modifier, to the same V-channel (s) unblocks the channel (s) and allows them to again be scanned by the Network Module.
Command:
[NOD xxxx] RST CH n:ss:cc[-n:ss:cc]...
[
,n:ss:cc[-n:ss:cc]
]
[/B]
For example, to block out V-channels 6 through 10 on the Voice Server Module in slot 12 of the
Control Mainframe, enter:
RST CH 1:12:6-1:12:10/B
To unblock those same V-channels from the blocked state, enter:
RST CH 1:12:6-1:12:10
Reset Driver Module (RST DR) Command
The RST DR command permits the user to transfer redundancy between driver 1 circuits and driver 2 circuits on the Driver Module, regardless of the error status.
Command:
[NOD xxxx] RST DR n
PRECAUTION: Transfers on active modules may cause momentary disruption of channel data traffic.

Reset Power Supply Module (RST PS) Command
The RST PS command is used to:
●
Determine if a faulty Power Supply Module exists in a redundant pair associated with a specific Mainframe.
●
Determine which Power Supply Module of the pair is faulty.
Command:
[NOD xxxx] RST PS n
NOTE:
This command does not apply to part number AW00642-1 Power
Supply Modules.
Under normal operating conditions, redundant Power Supply Modules in a LINK/2+ System share the power load. After issuing this command, the LINK/2+ System tests the operation of an individual Power Supply Module by drawing power for 2 minutes from only one power supply.
The Power Supply Module under test is identified by a lit ON LINE indicator.
A faulty Power Supply Module can be isolated as follows:
1.
Enter a CLR AQ command to clear the alarm table.
2.
Enter the RST PS n command to test one Power Supply Module. ON and ON LINE indicators light on Power Supply Module now in use. ON indicator lights on Power Supply
Module NOT in use.
3.
If alarm 04 is not displayed within approximately 2 minutes, the Power Supply Module under test is operational.
Set Database Checksum (SET CKS) Command
The SET CKS command calculates and stores a new database checksum on the online Network
Module. The checksum is updated each time the database is changed, that is, a parameter change.
The checksum computed by the SET CKS command is a total recalculation of the checksum.
The checksum is used to detect any corruption of the database.
Command:
[NOD xxxx] SET CKS
The database checksum is tested whenever the LINK/2+ System is turned on or the online
Network Module is reset. During a checksum test, the checksum is calculated again and compared to the previously stored checksum value. If the values do not agree, the LINK/2+
System reports a database checksum error. In general, a checksum error indicates either a hardware failure or a change in the database by an electrical transient. Use the DSP CKS command to determine if a checksum error exists.
L2UG
6/30/97
7-67
If a database checksum error is reported, enter the SET CKS command. Determine the error that needs to be corrected by checking the database, and make the appropriate changes to the database. The SET CKS command recalculates the checksum but does not correct the error.
NOTE:
If the database has been previously backed up using the SAV DB command, the database should then be restored using the procedure described in Appendix C of the Installation and Maintenance
Manual.
The value determined by the SET CKS command is stored in memory, and the value calculated in all subsequent checksum tests will be compared to the stored value.
Set and Clear Alarm Relay (SET RLY, CLR RLY) Commands
A test of the major and minor alarm relays is conducted using the SET RLY and CLR RLY commands. The SET RLY command causes the contacts of the major and minor alarm relays on the Network Module to close (alarm condition). The CLR RLY command causes the alarm relay contacts to open, restoring the relays to their normal operating condition.
Commands:
[NOD xxxx] SET RLY
[NOD xxxx] CLR RLY
When the alarm relay contacts are closed, either by the SET RLY command or because of a real alarm, these contact closures are presented to the user via the supervisory port connector. Also, a control signal conforming to RS-423 is provided at the Control Mainframe rear panel connector
1D, where:
+6V = relay test activated
-6V = relay test not activated
See the LINK/2+ Installation and Maintenance Manual for cabling information.
A major alarm occurs whenever:
●
A clock (phase locked loop) failure occurs (alarm 5).
●
ALL intermachine links at a node are declared out-of-service (alarm 7).
●
A Bypass Module fails (no redundancy) or both Bypass Modules fail (redundancy) (alarm
13).
●
Both circuits on a Driver Module fail (alarm 14).
●
ALL intermachine links are down as a result of a LINK/CSU failure (alarm 16).
●
The active master clocking node’s clock source is its internal oscillator (alarm 23).

A minor alarm occurs when the LINK/2+ System is still operational but some failure or error condition exists. Minor alarms are generated by alarms 2, 3, 4, 8, 9, 10, 11, 12, 15, 21, 22, 24,
25, 26, 27, 28, 30, 31, 32, 33, 34, and 35. In addition:
●
Alarm 7 is minor when one or more Interlink Modules or Integrated Trunk Module proprietary bundles are out-of-service.
●
Alarm 13 is minor when one Bypass Module of a redundant pair fails. If both Bypass
Modules fail at a node, alarm 13 is major.
●
Alarm 14 is minor if one circuit of a Driver Module fails. If both circuits of a Driver Module fail, alarm 14 is major.
●
Alarm 16 is minor if one or more intermachine links are down as a result of a LINK/CSU alarm. If ALL intermachine links are down, alarm 16 is major.
Set and Clear Tone Generator (SET TON, CLR TON) Commands
The SET TON command initiates a milliwatt reference equivalent test tone on a specified noncontending DS-0 channel. When used with DS-0 channel loopback commands, the SET TON command allows a DS-0 channel to be tested with a known reference signal. The CLR TON command stops the test tone generator on specified DS-0 channel(s).
If the test tone is used with DS-0 contention channels, these channels should be defined as noncontention channels before applying the test tone.
Commands:
[NOD xxxx] SET TON
{
EQ or LI
}
n:ss:cc
[{
/mmm or /P
}]
where: EQ = tone directed toward the DS-1 (or E-1) trunk, that is, toward the external equipment
LI = tone directed away from the DS-1 (or E-1) trunk toward an Interlink Module,
I/O module, Voice Processor, or Channelized Services Processor, that is, toward the LINK network
/mmm = number of minutes (1-240) after which test tone is cleared automatically
(default is 2 minutes)
/P = permanent; test tone will not be cleared automatically
[NOD xxxx] CLR TON
{
* or n:ss:cc[-n:ss:cc]...
[
,n:ss:cc[-n:ss:cc]
]}
NOTE:
To test more than one DS-0 channel on a Voice Processor or
Channelized Services Processor at the same time, the test tones must all be set toward the same direction. If a test tone is set in the opposite direction, that command will be rejected.
Test tones can only be used on Channelized Services Processors with a bundle size of 1.
L2UG
6/30/97

Equipment Test
The test tone begins at the internal tone generator on the specified Voice Processor or
Channelized Services Processor and flows toward the DS-1 (or E-1) trunk via the DS-1 (or E-1) interface, Figure 7-39.

Figure 7-43. Typical Test DS-0 Channel (TST DS0) Command
The following conditions and results apply when the TST DS0 command is issued:
●
The DS-0 channel must be connected.
●
The TST DS0 command can only be executed on channels that are not compressed. Attempts to issue a test on ADPCM channels will be rejected, and the message "ILLEGAL" is displayed at the supervisory terminal.
●
If a test tone is not already activated on the DS-0 channel, the Voice Processor will issue a test tone, and then will remove it when the test is finished.
●
If a test tone is already activated on the DS-0 channel, but the tone is in the opposite direction, or if other DS-0 channels have tones in place in the opposite direction, the command will be rejected.
●
The test command requires that a digital loopback be activated somewhere on the channel to be tested. If no loopback exists, or if the loopback is analog, the test will report FAIL.
●
The TST DS0 command cannot be issued from the supervisory terminal if the command has already been issued from a supervisory computer. Otherwise, the message "IN PROG" is displayed at the supervisory terminal.
L2UG
6/30/97

●
The TST DS0 command should not be used with contention DS-0 channels. To test contention DS-0 channels, the channels should be defined for noncontention before proceeding.
Test Generator and Clear Test Generator (TST, CLR MG) Commands
A complete or partial test of data, analog voice, or EIA control functions is established by the
TST command. To loop the test path from the internal test generator to the internal test detector, test generator commands are used with loopback commands. The CLR MG command stops and clears the test generator for partial tests 1 and 2. This command also removes an I/O channel from monitor mode. The CLR MG command should be entered before each loopback test to ensure that the byte counters are cleared.
NOTE:
Do not run test generator at channel rates above 392 kbps.

The test begins locally at the internal test generator, is looped by a selected I/O module channel loopback command, and flows through an Interlink Module across the intermachine link or through a Voice Processor until the flow is looped again. The test signal then returns to the local test detector. See Figure 7-44B for an example.
EIA Control Functions Tests
The complete (CNT C) EIA control functions test checks EIA functions both in ON and OFF status. The complete test results are automatically displayed on the supervisory terminal.
Partial test 1 (CNT P1) checks only EIA control functions in the OFF condition. Partial test 2
(CNT P2) checks EIA control functions in the ON condition. The results of the partial tests are displayed using the DSP TST command.
Data Flow Tests
The complete (DAT C) data test checks two alternate data bit patterns. The test results for the complete test are automatically displayed on the supervisory terminal.
Partial test 1 (DAT P1) checks a constant data bit pattern. Partial test 2 (DAT P2) checks a constant data bit pattern that is different from the P1 bit pattern. The results of the partial tests are displayed using the DSP TST command.
NOTE:
The test generator commands (TST) cannot be used with Subrate
Channel Processor channels. Channel loopbacks on a Subrate
Channel Processor are controlled by manual switches on the module.
End-to-end testing of subrate channels is the responsibility of the
Central Office terminating these channels. See Troubleshooting chapter in LINK/2+ Installation and Maintenance Manual for information on Subrate Channel Processor testing.

Regulatory Guidance
It is considered a criminal offence to install Telecommunications Terminal
Equipment which is not approved, or to install it in a non-compliant manner. Advice should be obtained from a competent Engineer BEFORE making Public Network
Connections.
European Telecommunications Regulatory legislation is concerned mainly with the following aspects of connection to Public Telecommunications Networks:
1.
That all equipment in a Network connected directly or indirectly to a public network is approved, and appropriately marked to show this.
2.

Analog Voice Barrier (AVB) Module
To protect the Safe Extra Low Voltage (SELV) circuits of the LINK/2+ System from Telephone
Network Voltages (TNV), voice ports must be connected via an AVB Module if the PABX port does not guarantee isolation from TNV circuits. If the PABX port classification is unknown, an
AVB Module should be used. Note that AVB Modules should only be used with /B variants of the Voice Modules.
PRECAUTION: /B variants MUST NEVER be used without AVB modules.
European Public Network Interface Cables (Eurocables)
With the advent of Pan-European Public Network Interface Standards, Ascom
Timeplex Equipment is approved for connection to European Public Networks using specific cables applicable to the European Marketplace, and required to maintain
Safety and Electromagnetic Compatibility (EMC) compliance. These cables form part of the Attachment Approval and should be ordered using their associated Part
Numbers.
To maintain full compliance with the Interface specifications, attention is drawn to the maximum and minimum lengths, and baud rates specified on some interfaces.
For reliable operation, references are made to CCITT documents which recommend the expected relationship between cable length and baud rate.
Ascom Timeplex has taken into account the following aspects of cable design to ensure compliance with European legislation applicable to equipment used in
"Commercial and Light Industrial" environments:
•
Impedance/meter
•
EMC Earthing practices
•
Interface connections
•

Speech Traffic
The LINK/2+ product is capable of carrying speech traffic between nodes. Swiss regulations permit the carrying of "Private Voice" traffic which may originate and terminate on PABX’s, or on equipment not permitting the conveyancing of traffic from a third party.
PSTN speech may only be carried using PCM 64 kbps algorithms and the speech quality must be certified by BAKOM. Ascom Timeplex has not obtained this certificate from
BAKOM and therefore only private speech traffic may be conveyed at this time.
