Emulex DCP_link
Emulex DCP_link is a multi-protocol router including WAN connectivity software and one of the DCPx86i/e family of communications adapters.
DCP_link is designed to work in conjunction with the Novell NetWare
Branch Link and Enterprise Router, formerly known as the Novell
MultiProtocol Router (MPR 3.0). This unique adapter and software combination provides remote connectivity across numerous interfaces, protocols, network types and hardware platforms.
Through Novell ODI specification compliance, Emulex DCP_link adds the integrated hardware and software components necessary for remote WAN connections on NetWare LAN environments. In addition to the WAN adapter, specialized interface modules and protocol stacks are included to allow upper-level applications the transparent network link to run over multiprotocol configurations.
A copy of Novell MPR 3.0 (Branch Link or Enterprise version) is included with DCP_link, and must be installed prior to installation of DCP_link.
NOTE: Please refer to the Novell MPR installation
instructions outlined in Chapter 5 of the Novell
NetWare MultiProtocol Router 3.0 Installation
and Basic Configuration Guide included with
DCP_link.

DCP_link features an 80x86 microprocessor based “intelligent” WAN adapter to provide powerful co-processing capabilities. The adapter utilizes
1Mb of on-board shared memory to transfer commands and data to the
NetWare server. DMA channels are included to support full-duplex operation.
This chapter describes the factory default configuration of the
DCP286i/386i/486e and tells how to configure the board for WAN applications.
Factory Default Settings
This factory default configuration is correct for all WAN applications:
• DCP286i, DCP386i and DCP486e compatibility level
• 1 Megabyte memory size
• Window Group Select 16K, 32K, 64K, 1MB
• Control Register 4 Read option enabled
IMPORTANT: The base I/O address and the IRQ level
must not be in conflict with any other adapter on the server. Verify that both the base I/O address and the interrupt level (IRQ setting) configured on the adapter match the software configuration. For
more information, refer to Chapter 6.
Verify that the following factory default parameters are appropriate for your server environment. If you can use the factory default configuration, refer to the DCP_link Quick Start User’s Guide.
Base I/O address
Interrupt Level (IRQ)
Data clock direction
33C hex
3
DTE
Hardware Configuration 2-3
NOTE:
The Base I/O address and IRQ settings are the same for all adapters. Data Clock Direction, DTE, is correct for all connections except V.35.
Other switch or jumper settings unique to an individual adapter type (i.e.,
DCP286i-SBC, DCP386i, or DCP486e) are detailed in a separate section of this chapter specific to each adapter.
Base I/O Address
The Base I/O address is selected via switch SW1, which may be labeled CR
ADDR (Control Register Address) on some adapters.
The adapter requires four bytes of I/O locations for its control registers.
These control registers are used by the server CPU to coordinate and service information provided by the adapter. The address of these registers depends on the setting of switches SW1-1 through SW1-4. The factory default is set to 33C hex.
Figure 2-1 shows the possible settings for the Control Register 1 address. To locate the position of SW1 on the adapter, refer to the appropriate diagram in the following sections for the adapter type you are installing (i.e. 286, 386 or
486).

The factory default setting (J1-5 to J1-6 connected) allows window sizes of
16K, 32K, 64K or 1MB. By removing this jumper, window sizes of 16K,
64K or 128K are made available.
Memory Size
The memory size on the board, 512 kB or 1MB, is selected by jumper position J1:7-8. The DCP286i-SBC is shipped with 1 MB of Dynamic
RAM. Remove this jumper to select 512 kB of RAM.
Hardware Configuration 2-9
Setting Data Clock Direction (DTE or DCE)
J7, J8, J9 and SW-3 set the synchronous data clock direction (DTE or DCE) for port 1. Jumpers J4, J5, J6 and SW2 set the synchronous data clock direction (DTE or DCE) for Port 2.
Figure 2-7 Factory Default DTE Settings All Modes Except V.35
NOTE: DTE OPERATION RS422: In the RS422 mode
additional flexibility is provided to terminate receivers with 100 ohm resistors. If termination resistors are required in this mode, additional switches SW3 - 2, 3 and 4 should be CLOSED (SW2 for Port 2).

Hardware Installation 3-3
This section describes the procedure for installing the DCP286i-SBC, the
DCP386i, and the DCP486e WAN adapter in your server/router. Brief troubleshooting procedures are also provided.
Installing the Emulex Adapter
To install the adapter perform these steps:
1) Turn off power to the system unit. Remove the power cord from the unit and the AC outlet.
2) Loosen attaching screw and remove the top cover of the system unit.
3) Remove the cover from an empty slot. The DCP286i-SBC and DCP386i may be installed in a 16-bit ISA and EISA slot. However, the DCP486e must be installed in an EISA slot.
4) Slide the board into the empty slot. Press firmly to seat the board.
5) Secure the board with the screw removed in step 3.
6) Replace the system unit cover and reconnect the power cord.
7) Connect cable.
Before connecting the external device, you may want to perform a complete functional test of the unit. Refer to Section 4 for instructions on running the diagnostics.
3-4 Chapter 3
Cabling Connections
Cabling specifications for each adapter type (DCP286i-SBC, DCP386i and
DCP486e) are found in the following section. Cabling differences will be noticed when connecting a DTE port to a DCE device (normally a straight through cable), and when connecting a DTE port to a DTE device (normally a null modem cable). Factory setting on all cabling is DTE.
Factory Default Settings
DCP286i-SBC Adapter Cables
The DCP286i-SBC adapter is shipped with two standard adapter cables which convert the Micro-D25 male output to a standard DB25 output. Install the adapter cable for the environment in which you are working:

DCP386i/486e Daughterboard Cabling
This section discusses cable connections between the 8-port daughterboard on the DCP386i and DCP486e adapters and external devices.
RS-232 Cabling
The serial ports on the 8-port daughterboard are connected to external devices via an 8-port breakout cable. Each port provides a standard 25-pin male RS-232C connector for attachment to external devices.
To connect the port to a modem or other DCE device, use a standard straightthrough cable as shown in Figure 3-10.
If you are connecting the port to a DTE device, such as a terminal or another computer, you must use the null-modem cable shown in Figure 3-11.
If your device and application software do not require any modem or clock signals (async only) the three-wire cable shown in Figure 3-15 may be used.
NOTE: All connections to the board should be made using
shielded cables to reduce radio frequency interference.
Contact Emulex Sales Support for further information regarding price and model number of any support cables.
IMPORTANT: In order to provide proper strain relief it is recommended that the breakout cable not be freely suspended from the PC chassis. If this is necessary, the breakout cable should be secured to a chassis or rack. This will help prevent the loss of electrical connection between the adapter and the cable.

Troubleshooting
If you experience a problem immediately after installing the adapter, check these areas:
1) Is the device cable the correct type? Some asynchronous cables do not have enough wires to support the additional signals required for synchronous communications.
2) Is the board securely seated in the system unit?
3) Are any connections to other boards loose?
4) Are the cable connections made properly? Are the connections loose?
5) Are the factory-set jumpers and switches set correctly?
6) Is the power cord loose in the wall socket or at the rear connection to the system unit?
7) Are the external equipment connections made properly and is the equipment powered on?
If the problem still remains, run the DCP286i/386i/486e diagnostic. This program performs a complete check of all functional areas on the board.
Refer to Appendix A for operation of the diagnostic software. Report any errors to Emulex Technical Support by calling the phone numbers listed in the front of this guide.

INETCFG
The Internetworking Configuration utility (INETCFG) is a menudriven utility used to configure the Emulex software.
You can run INETCFG while the router or server is operating. Each time the utility is used, it reads the existing AUTOEXEC.NCF file and optionally transfers the LOAD and BIND commands to a configuration file that is referenced at system initialization (or reinitialization). This eliminates manual reconfiguration of existing servers. Always allow INETCFG to automatically update configuration when prompted.
You must use INETCFG to configure the network environment.
Warning: Do not use text editors to modify the configuration. Directly editing the
INETCFG files may cause the system to encounter serious problems requiring a complete reload of the Netware operating system
Most configuration changes take effect only after you bring down the system and restart it. For example, if you enable or disable a board, or change parameters on a board, you must bring down the server and restart the system.
INETCFG Menus
INETCFG uses a series of menus, windows and dialog boxes to configure related sets of parameters. This configuration interface allows you to enter names of new interfaces, specify parameters and override defaults without having to use the command line.
The items in the main Internetworking Configuration menu correspond to the basic steps used to configure Emulex DCP_link.
These items should be configured in the order presented in the configuration procedures.
Software Configuration 5-3

Introduction
Emulex Frame Relay software is a streamlined, connection-oriented framemode data service based on frame-switching /relaying technology--the process of quickly transporting HDLC (High-level Data Link Control) frames through a network.
This software is based on
Frame Relay
, a WAN telecommunications protocol standard specified by the International Consultative Committee for
Telegraphy and Telephony (CCITT) and ANSI (American National
Standards Institute). Frame Relay was originally specified by CCITT as an
Integrated Services Digital Network (ISDN) frame-mode service.
Emulex Frame Relay supports AppleTalk, Transmission Control
Protocol/Internet Protocol (TCP/IP), Internetwork Packet Exchange (IPX) protocol, and the Source Route Bridge protocol of the NetWare
MultiProtocol Router 3.0 software.
Frame Relay Networks
Private line networks permanently allocate dedicated transmission resources between communication end points, regardless of traffic conditions. The
Frame Relay network uses statistical multiplexing. Transmission resources are not allocated until active communications exist. Network resources are shared dynamically among participating end points.
Frame Relay networks provide the best features of TDM (time division multiplexing): high-speed, low-delay circuit switching and the statistical multiplexing and port sharing of X.25 packet-switching technologies. These advantages guarantee bandwidth according to the set committed information rate (CIR), and allow bandwidth-on-demand bursts when available.
The Frame Relay network consists of Frame Relay switches, which usually are owned and administered by the carriers. The access connection to the
Frame Relay network is typically provided by a Local Exchange Carrier
(LEC) and can also be bundled into the Frame Relay provider's service. A network provider can be an LEC; a Metropolitan Frame Relay service, an
Interexchange Carrier (IXC), an interstate, national, or global Frame Relay service.
Frame Relay Configuration 6-3
Emulex Frame Relay encapsulates data frames and routes them through the
Frame Relay network based on the Data-Link Connection Identifier (DLCI), which identifies the local permanent virtual circuit (PVC) end point of the router. DLCIs are defined through the configuration process or teamed through the Emulex Frame Relay link management protocol.
A Frame Relay network has the following characteristics:
• Transports frames transparently. The network modifies only the DLCI, congestion bits, and frame check sequence (FCS).
• Detects transmission, format and operational errors.
• Preserves the order of the frame transfer on individual PVCs.
• Does not acknowledge or retransmit frames.
Using Emulex Frame Relay, you can have a logical end-to-end link (a virtual private line) between communication end points. Although Emulex Frame
Relay appears as a dedicated private network to the user, the virtual circuits and high-speed internode trunking make it a more cost-effective service than a dedicated line service, with similar performance. It is intended primarily for high-speed, burst data communications applications, such as WAN interconnections.
Frame Relay Parameters
Emulex Frame Relay network service parameters, which are determined at subscription time, are in effect on a per virtual circuit basis. To set up and use
Emulex Frame Relay, the following parameters must be configured before
Frame Relay link activation:
Data Link Connection Identifiers
(DLCls) are the PVC numbers that you need for data transfer (one DLCI denotes one end of a virtual circuit). Two DLCIs, one at each end of the connection, are required to form one end-to-end virtual circuit. The DLCI is also known as the virtual circuit number.
When a client workstation needs access to a remote LAN, the Emulex Frame
Relay router sends the frame to the local Frame Relay network switch which then sends it through the network to the remote end LAN.
Minimum committed bandwidth access is enforced using the CIR protocol feature. If a user exceeds the specified CIR limit, a risk of dropped packets exists. However, users working within their set CIR are usually guaranteed delivery by the service provider.
6-4 Chapter 6
The Frame Relay network switch monitors the access rate and size of data frames transferred through the mesh network. The data throughput CIR is guaranteed by the network, but allows for excess bursts (Be) of data not to exceed the access rate (AR) of the connection. The committed burst size (Bc) sets the maximum amount of data that the network agrees to transfer in a specified time period.
Bursting above the set CIR is allowed only if the connection is configured for it and the actual bandwidth is available on an end-to-end basis. This means that the entrance edge node into the Frame Relay network, the transit nodes within the network, and the exiting edge node from the network must be available before excess bursting can occur.
Diagramming Your Frame Relay Network
To ensure that all the desired connections to the Frame Relay network are properly diagrammed, complete these steps:
1) Diagram the existing Frame Relay network showing all router access points.
2) Draw each connection from the local router to its corresponding partner.
3) Indicate the DLCI number assigned by the network for each connection
(PVC).
Planning Your Frame Relay Network
Specify the following parameters to ensure that all aspects of your connections to the Frame Relay network are covered:.
Contact your Frame Relay network service provider and request the specific parameter values you require.The Frame Relay network provider will set up your service and assign DLCI numbers to each PVC.
Frame Relay Local Router ID
- Symbolic name assigned by the system administrator to identify a particular Emulex Frame Relay router. The ID is arbitrary and provides a way to track or reference a particular Emulex
Frame Relay router. The Number of partner routers connected using
Frame Relay is also important.
Physical Type
- The type of connection between the Frame Relay switch and the Emulex Frame Relay router. (for example, V.35 or RS-232).
Interface Speed
- External or internal. Internal speeds vary with the driver used. For example, if you have an application that must
Frame Relay Configuration 6-5
communicate with three remote sites using a minimum of 32 Kbps sustained bandwidth, the physical interface must be able to support at least 3 x 32 Kbps = 96 Kbps. You should also consider traffic pattern characteristics (bursty or sustained) when specifying interface speed.
Encoding Option
- Corresponds to the encoding set on the physical line to which the Emulex Frame Relay router is attached. It can be NRZI
(nonreturn to zero inverted) or NRZ (nonreturn to zero).
Destination (Partner)
- Destination name at the remote end of a PVC that connects communication partners.
DLCI
- Number-Data Link Connection Identifier number assigned by the
Frame Relay network service provider for each PVC.
When you have completed all the planning steps for the Frame Relay connections, configure your Emulex Frame Relay software as described below.

Introduction
Emulex X.25 software operates in a NetWare server or NetWare router/bridge PC environment and provides services for NetWare products and other applications (including independent developer applications) requiring wide area connectivity
Emulex X.25 uses the 1984 CCITT X.25 Recommendation, which defines the interaction between data terminal equipment (DTE) and data circuitterminating equipment (DCE) of a packet-switching network.
In general the end user equipment (mainframe, pad, server) is DTE and the service provider (X.25) is DCE. In the illustration we see an example of a call established between two DTE connections.
IBM Compatible
DTE DCE
X.25
DCE
Novell Server
DTE
DTE and DCE are both responsible for establishing, maintaining, and terminating the connection. The X.25 protocol primarily services between a
DTE/DTE pair providing the DCE connection.
As described earlier the Emulex X.25 implements the 1984 CCITT X.25 recommendations, including the level 1 (physical), level 2 (frame), and level
3 (packet), along with several library modules. All three levels are generally configured as either DTE or all three as DCE though exceptions can occur.
For example a DCE which accepts clock signals from a modem would have level 1 configured as DTE ( interface speed set to external).
Emulex X.25 interface runs in conjunction with NetWare MultiProtocol
Router 3.0 and supports a wide variety of other proprietary software platforms.
X.25 Configuration 7-3
Virtual Circuit Service
X.25 uses two mechanisms, providing a logical path between end points, called virtual circuits. A virtual circuit provides a connection-oriented service, similar to that of circuit switching but with the following exceptions:
• Limited to a connection between two end points.
• Economical statistical multiplexing for establishing a logical path through the network.
There are two virtual circuits types: switched virtual circuits (SVCs) and permanent virtual circuits (PVCs). An SVC is a dynamically established virtual circuit using “call setup” and “call clearing” procedures. A PVC is a permanent, network-assigned virtual circuit that requires no call setup or clearing and operates like a logical leased line.
Using mixed protocols, the router can maintain multiple connections using
SVCs between multiple sites. SVCs can be set up to operate automatically or on demand as data and call requests dictate. The router can automatically establish and disconnect on-demand IP connections using SVCs.
The types of connections supported by Emulex X.25 for various protocols are shown in the following table.
SVC
APPLETALK X X X
BRIDGE X X
A permanent SVC is established at initialization and is left in a connected state until the user or application brings it down. An on-demand SVC is established only when data is present for the associated virtual circuit and is brought down after the data has been transmitted and the configured idle timer has expired. An on-demand SVC remains down until more data is queued up to be sent, at which time the connection is reestablished.
Once a virtual circuit is established, data packets using this circuit are automatically sent to the appropriate destination
7-4 Chapter 7
Logical channels differentiate the virtual circuits supported by the packet level. Each packet is associated with a logical channel which is mapped to the appropriate destination of the virtual circuit. Multiple connections are provided simultaneously by multiplexing virtual circuits over the access line.
This enables a more effective use of the access circuit for the available bandwidth and the traffic density for each logical channel.
Note
: Only one PVC or SVC can be established at a time on each logical channel.
Logical Channel Numbers
The logical channel number is embedded in a 12 bit field within the packet.
For SVCs, the association between a logical channel identifier and a particular virtual circuit is accomplished at call setup time when the identifier is chosen from a pool of unused identifiers. The logical channel number is determined by the X.25 service provider for that particular network subscription.
At network subscription time, the user specifies the number of logical channels needed for both SVCs and PVCs by designating ranges of logical channel numbers. Emulex X.25 configuration uses the decimal equivalent of the complete 12-bit Logical Channel Identifier in two subfields: the Logical
Channel Group (4 bits) and the Logical Channel Number (8 bits).
Within any of the following categories, the range of available logical channels must be continuous. Each successive range of logical channel numbers must be numerically higher than the previous range.
In increasing order, the logical channel ranges are:
1) PVCs
2) SVCs supporting only calls from the network (inbound SVC)
3) SVCs supporting calls from and to the network (two-way SVC)
4) SVCs supporting only calls to the network (outbound SVC)
NOTE: The total number of logical channel on all ports on
an Emulex card should not exceed 255.
X.25 Configuration 7-5
Diagramming Your X.25 Network
To ensure that all connections to the X.25 network are properly diagrammed, complete these step:
1) Diagram the existing X.25 network showing all router access points and mark the X.25 addresses.
2) Draw each type of connection from the local router to its corresponding partner.
For PVC-type connections, show the LCN assigned by the X.25 network service provider and the partner name.
For SVC-type connections, list the partner names.
Planning Your X.25 Network
To ensure that all aspects of your planned connections to the X.25 network are covered, complete the following steps:
For each location that a router attaches to the X.25 network, specify the following parameters:
− Physical interface required (for example, V.35 or RS-232)
− Internal interface speed required (for example, 9600 or 19200)
This value is needed only when the clocking is generated internally; otherwise, clocking comes from the modem.
Number of partner routers which will be connected using X.25 and whether a PVC or an SVC is required for each.
− Packet size required (for example, 128 bytes or 256 bytes)
Emulex X.25 Router ID
(at top of page) - Symbolic name assigned by the system administrator to identify a particular Emulex X.25 router. The
ID provides a way to track or reference a particular Emulex X.25 router.
Frame Level Parameters
Sequencing Modulo
- Specifies the numbering of sequential frames allowed in a Data-Link layer window. Modulo 8 is specified for 1984
CCITT X.25 Specifications.
Window Size (k) -
Determines the maximum number of unacknowledged frames that can be received or sent before requiring an acknowledgment by the remote destination.
7-6 Chapter 7
Maximum Frame Size (Nl)
- Determines the maximum frame size (in octets) allowed to be received on the link. It is automatically configured from the packet size and maximum packet size information.
Retry Count (N2) -
Determines the maximum number of times a frame should be retransmitted because of the expiration of the Retry Timer (Tl).
A large value for this parameter increases the probability of a correct transfer between the DTE and DCE. A small value permits faster detection of a permanent error condition.
Retry Time-out (TI) -
Determines the time, in seconds, to wait for an acknowledgment of the oldest transmitted frame. If no acknowledgment is received within this set time, an attempt is made to determine the status of the remote device.
Disconnect Time-out (T3) -
Displays the value of the T3 timer. After attempting to connect the link by sending N2 Set Asynchronous
Balanced Mode (SABM) frames on TI expiration, the Data-Link layer continues sending SABM frames when the T3 timer expires. This setting isn’t configurable.
Idle Time-out (T4)
- Specifies the amount of time the local DTE waits
(when a link becomes idle) before attempting to poll the partner node for status. If the partner node does not respond to the polls, the link is reset and all current virtual calls are cleared or reset. This setting isn’t configurable.
Frame Node Type
- The X.25 frame level configures DCE/DTE protocol handshaking. Generally, an X.25 service provider will require
DTE.
Packet Level Parameters
Local DTE Address-
Specifies the X.25 address (up to 15 digits) of the local DTE. It should match the address assigned by your attached network. This address is included in the Calling Address field of the outbound Call Request packets.
Version -
Emulex X.25 specifically supports 1984 CCITT X.25
Recommendation
Role -
Determines whether you use DTE or DCE procedures for packet layer operation in the Logical Channel Number (LCN) assignment.
X.25 Configuration 7-7
When establishing a connection to an X.25 network, you must set this parameter to DTE (the default value) if you are connecting to a X.25 service provider.
Default Inbound/Outbound Packet Size -
The Inbound Packet uses the default packet size for a inbound call unless another packet size is specified. Set this value to correspond to your network subscription. The
Outbound Packet determines the maximum out going data packet size when a call is established without the Flow Control Negotiation parameter. The default Outbound Packet Size should be a value that is agreed upon by the PDN and the remote DTE.
Sequencing Modulo -
Control over the numbering of sequential data packets allowed in a window. Emulex X.25 only allows Modulo 8.
Default Window Size
- Specifies the default value of the maximum number of sequentially numbered data packets that can be transmitted by the local DTE without receiving an acknowledgment at any given time.
When a virtual circuit is established without flow control negotiation, this value is used as an outbound window size. You should set this parameter to the value agreed upon by the PDN.
Note:
The following timers and counters are not configurable.
T20 (Restart Response Timer) -
Determines the amount of time, in seconds, that the local DTE waits when it issues a Restart Request packet to receive a restart confirmation or restart indication. When the time limit expires, the Restart Request packet is retransmitted.
T21 (Call Response Timer) -
Specifies the amount of time, in seconds, that the DTE waits for a response to an outbound Call Request packet.
T22 (Reset Response Timer) -
Specifies the amount of time, in seconds, that the DTE waits for a response to a Reset Request packet.
T23 (Clear Response Timer -
Specifies the amount of time, in seconds, that the DTE waits for a response to a Clear Request packet.
T24 (Ace-Send Timer) -
Specifies the amount of time, in seconds, that a
DTE waits when a packet carrying a valid acknowledgment is sent.
This timer is used to ensure that no acknowledgment is lost. If the timer expires, an RR (Receiver Ready) packet is sent.
7-8 Chapter 7
T25 (Data Packet Retransmission Timer) -
Specifies the amount of time, in seconds, that the DTE waits for the appropriate acknowledgment after transmitting a data packet. If the T25 timer expires, the packet layer resets the virtual circuit.
T26 (Interrupt Timer) -
Specifies the amount of time, in seconds, that the
DTE waits when an Interrupt Request packet is sent for an interrupt confirmation to be received. If the T26 timer expires, the packet layer resets the virtual circuit.
R20 (Restart Retransmission Timer) -
Specifies the maximum number of times the local DTE retransmits, upon expiration of the T20 timer, before notifying the user that the associated link is inoperative.
R22 (Restart Retransmission Counter) -
Determines the maximum number of times the local DTE retransmits a Reset Request packet, upon expiration of the T22 timer, before initiating a Clear procedure for SVC or a Restart procedure for PVC.
R23 (Clear Retransmission Count) -
Determines the maximum number of times the local DTE retransmits a Clear Request packet upon expiration of the T23 timer, before initiating a Restart procedure on the associated link.
Logical Channel Numbers
PVC, Lowest LCN -
Determines the lowest LCN used for a PVC.
PVC, Number of LCNs -
Determines the number of logical channels supporting PVCs. This number must agree with your network subscription.
Inbound SVC, Lowest LCN -
Determines the lowest LCN that can be used for one-way incoming logical channels for SVCs. This value must be greater than or equal to the lowest PVC LCN parameter value.
Inbound SVC, Number of LCNs -
Determines the number of incoming channels assigned for inbound-only SVCs.
This number must agree with your network subscription.
Two Way SVC, Lowest LCN -
Determines the lowest number of twoway channels assigned for SVCs that can be used for both inbound and outbound calls.
X.25 Configuration 7-9
Two Way SVC, Number of LCNs -
Determines the lowest LCN that can be used for two-way SVCs. This number must agree with your network subscription.
Outbound, Lowest LCN -
Determines the lowest LCN that can be used for outgoing logical channels for SVCs. The value must be greater than or equal to the Lowest two-way SVC LCNs value plus the Number of two-way LCNs value.
Outbound, Number of LCNs -
Determines the number of logical channels reserved for outbound-only SVCs. This number must agree with your network subscription.
Emulex X.25 User Facilities
The X.25 Recommendation addresses users' needs for versatility in their network requirements through a set of optional user facilities. These facilities give X.25 the capability of being tailored to meet varied network and user requirements and allow a network installer to fine-tune the network’s handling of such areas as security, accounting, routing, and performance.
These facilities can be selectively and incrementally specified to the needs of the users on that network.
Many user facilities can be used within an X.25 connection to a PDN. Some of these facilities are read-only and may not be changed. User facilities available with Emulex X.25 include the following:
Flow Control Negotiation
- If set to
Yes
, negotiates (downgrades) incoming calls containing either Window Size or Packet Size facility values that are greater than those specified. If set to
No
, rejects incoming calls containing either Window Size or Packet Size facility values that are greater than those specified. Negotiates, on a per-call basis.
Throughput Class Negotiation
- Specifies, on a per-call basis, the throughput of data that can be transferred on a virtual circuit. The range is 75 bps to 64 Kbps.
Fast Select
- If
Yes
, allows up to 128 bytes of user data to be included in Call Request packets. If
No
, user data is not included in Call Request packets Expands the Call and Clear user data fields from the normal 16 octets to 128 octets, enhancing the data field's usefulness for shortduration, low-volume, transaction-oriented applications. This facility is often used in the retail point-of-sale and credit card authorization terminal environment..
7-10 Chapter 7
Reverse Charging Calls
- Offers the equivalent of a collect call. It is allowed on a per-call basis and is specified in the Call Request packet by the calling DTE.
Closed User Group (CUG
) - Allows the configuration of one or more virtual private networks within a larger public network. A user may gather a number of DTEs into a single logical group and restrict the group’s access ability to receive incoming calls or to make outgoing calls to the restricted “open” portion of the network. The number of CUGs is network-dependent. A single DTE can belong to one or more CUGs.
Within the CUG category, you can specify whether a user connection has incoming access (CUG with Incoming Access), outgoing access (CUG with Outgoing Access), or both. If a DTE belongs to more than one
CUG, you must also specify a preferred (or primary) CUG.
Bilateral Closed User Group (BCUG)
- Offers a finer degree of access control than CUGs. Bilateral signifies a CUG relationship that has been limited to a pair of DTEs. Access between the pair of DTEs is unrestricted; however, access to or from any other DTE is not possible.
Maximum Packet Size -
Specifies the largest packet size that can be negotiated on a per virtual circuit basis.
Window Size -
Specifies the largest value, per virtual circuit, to be negotiated in a Window Size facility parameter field. The maximum value for this parameter is dependent upon which Packet Sequencing
Modulo method you selected.
D-Bit Procedure Authorization
- Not configurable
A DTE subscription with a PDN can include a provision to allow or disallow a remotely originated, reverse-charged call from reaching that DTE (Reverse
Charging Acceptance). Charged calls, that is, locally generated call requests, must specify reverse charging.
Emulex X.25 additionally provides local configurable options for both of the preceding items. Regardless of a customer's PDN subscription, all inbound reverse-charged calls can be rejected and all outbound call attempts that do not specify reverse charging can be disallowed.

Configuring the WAN Call Directory
The WAN Call Directory is a list of WAN Call Destination configurations you want to use for each virtual circuit. You must create at least one WAN
Call Destination configuration for each desired destination. WAN Call
Destination configurations contain parameters to be applied by Emulex X.25 software when establishing and maintaining calls to the destination.
Two basic types of call configurations are possible: permanent and ondemand. If the connection fails, attempts to reconnect are tried at periodic intervals. This type of connection is suited for use with dynamic routing protocols like RIP or NetWare Link Services Protocol (NLSP) software.
On-demand calls specify that the connection should be established only when needed. Maintenance data such as routing updates is suppressed. These types of connections are terminated whenever the link is void of network data longer than the configured Idle Line Time-out value. A connection failure is retried only when more network data is directed to the remote destination.
To configure WAN Call Destinations for X.25 interfaces, perform the following steps:
1) From the Internetworking Configuration menu, select
WAN Call
Directory
, and press <Enter>
Figure 7-6 Internetworking Configuration

or press
<Enter> to select
On-Demand
from the pop-up list.
Reminder: You must configure the X.25 Authentication
Options in the X.25 Profile if you select “ondemand” as the Call Type.
On-Demand calls are established only when needed. The connections are terminated whenever the link is void of network data. Termination is determined by the Idle Line Time-out value. A connection failure is retried only when more network data is directed to the remote destination.
On-demand calls can be placed through either a specific interface or an interface group, but not both.
− You can display a list of Interface Group names by pressing <Enter>.
− Select an X.25 interface group from the list, then press <Enter>.

This is the X.121 DTE address (up to 15 digits, 0 through 9) assigned to the specific destination DTE.
11) In the
Retry Mode
field, accept the mode shown or press <Enter> to select another option from the pop-up list.
This parameter specifies the conditions under which a failed connection is retried. All connection failures are reported to the system console and to the Call Manager utility (CALLMGR).
The available options are Never Retry, Retry All Failures, Retry Self-
Correcting Failures. The default is Retry Self-Correcting Failures.
12) In the
Retry Limit Handling
field, press <Enter> to select the appropriate option from a pop-up list.
This parameter specifies the action taken when the connection retry interval exceeds the
Retry Interval Limit
(described in Step 12).
For permanent calls, connection retries can either continue indefinitely at the maximum retry interval (which supports unattended operation) or be terminated (the connection fails).
On-demand calls can only accept
Stop At Limit
, which means the connection fails when the retry interval reaches the limit.
13) In the
Retry Interval Limit
field, accept the value shown or press
<Enter> to change it.
X.25 Configuration 7-21
This parameter specifies the maximum delay between attempts to establish a connection (the retry interval). The delay is set initially to 8 seconds and increases exponentially until the maximum retry interval is reached.
The range of time intervals is 00:00:00 to 23:59:59 (hh:mm:ss). For permanent calls, the default value is 10 minutes (00:10:00). For ondemand calls, the default value is 2 minutes (00:02:00).
14) In the
Idle Line Time-out
field, if Call Type is set to On-Demand, accept the value shown or press <Enter> to change it.
This parameter specifies the amount of time that an on-demand call can be inactive before closing the connection.
The range of values is 00:00:00 through 23:59:59 (hh:mm:ss). The default value is 10 minutes (00:10:00).
15) In the
Remote System ID
field, press <Enter> to display a list of X.25
Remote System Ids. This parameter is needed only if
Call Type
is set to
On-Demand
.
This parameter specifies the symbolic name (from 1 to 47 ASCII characters) of the remote peer system associated with this WAN Call
Destination entry, typically the remote system server name.
16) Use the arrow keys to select a Remote System ID, then press <Enter> accept or press <Ins> to create a new Remote System ID.
