This product is intended to be used with a three-wire grounding type plug — a plug
which has a grounding pin. This is a safety feature. Equipment grounding is vital to
ensure safe operation. Do not defeat the purpose of the grounding type plug by
modifying the plug or using an adaptor.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for
the presence of earth ground. If the receptacle is not properly grounded, the
installation must not continue until a qualified electrician has corrected the problem.
If a three-wire grounding type power source is not available, consult a qualified
electrician to determine another method of grounding the equipment.
3.
Slots and openings in the cabinet are provided for ventilation. To ensure reliable
operation of the product and to protect it from overheating, these slots and openings
must not be blocked or covered.
4.
Do not allow anything to rest on the power cord and do not locate the product where
persons will walk on the power cord.
5.
Do not attempt to service this product yourself, as opening or removing covers may
expose you to dangerous high voltage points or other risks. Refer all servicing to
qualified service personnel.
6.
General purpose cables are provided with this product. Special cables, which may be
required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
7.
When installed in the final configuration, the product must comply with the applicable
Safety Standards and regulatory requirements of the country in which it is installed. If
necessary, consult with the appropriate regulatory agencies and inspection
authorities to ensure compliance.
8.
A rare phenomenon can create a voltage potential between the earth grounds of two
or more buildings. If products installed in separate buildings are interconnected, the
voltage potential may cause a hazardous condition. Consult a qualified electrical
consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action prior to interconnecting the products.

Government Regulations and Equipment Return
Certain governments require that instructions pertaining to CSU and modem connection to the
telephone network be included in the installation and operation manual. Specific instructions are
listed in the following sections.
United States
NOTICE TO USERS OF THE UNITED STATES TELEPHONE NETWORK
1. This equipment complies with Part 68 of the FCC rules. On the equipment is a label that
contains, among other information, the FCC registration number and ringer equivalence
number (REN) for this equipment. The label is located on the bottom of the 3150 CSU, and
on the 3151 CSU’s circuit card. If requested, this information must be provided to the
telephone company.
2. There are two types of telephone lines associated with the standalone equipment. The T1
network connection should be made using a Universal Service Order Code (USOC) type
RJ48C jack. The Service Order Code 6.0F should be specified to the telephone company
when ordering the T1 line. In addition, the proper Facility Interface Code must be specified
to the Telephone Company. The CSU can be configured to support any of the following
framing format and line signaling techniques. The CSU’s configuration must correspond to
the T1 line’s parameters. The 3150 CSU’s internal modem connects to the Public Switched
Telephone Network using a USOC Type RJ11C jack. The Facility Interface Code 02LS2
along with the RJ11C jack should be specified to the telephone company when ordering a
dial line for the modem. The 3151 CSU connects to the T1 network using the multi-line
USOC-type RJ48H jack and does not have a PSTN interface.

3. The ringer equivalence number (REN) is used to determine the quantity of devices which
may be connected to the telephone line. Excessive RENs on the telephone line may result
in the devices not ringing in response to an incoming call. In most, but not all areas, the
sum of the RENs should not exceed five (5.0). To be certain of the number of devices that
may be connected to the line, as determined by the total RENs, contact the telephone
company to determine the maximum RENs for the calling area.
4. If the 315x CSU causes harm to the telephone network, the telephone company will notify
you in advance that temporary discontinuance of service may be required. But if advance
notice is not practical, the telephone company will notify the customer as soon as possible.
Also, you will be advised of your right to file a complaint with the FCC if you believe it is
necessary.

Canada
NOTICE TO USERS OF THE CANADIAN TELEPHONE NETWORK
The Canadian Department of Communications label identifies certified equipment. This
certification means that the equipment meets certain telecommunications network protective,
operational and safety requirements. The Department does not guarantee the equipment will
operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. In some cases, the company’s inside wiring associated with a
single line individual service may be extended by means of a certified connector assembly
(telephone extension cord). The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request to disconnect
the equipment.
Users should ensure for their own protection that the electrical ground connection of the power
utility, telephone line and internal metallic water pipe system, if present, are connected together.
This precaution may be particularly important in rural areas.

ACCULINK 3150 Channel Service Unit
Features
The 315x CSU offers a wide variety of features:
• Integral modem for 3150 CSUs only, which enables
remote operation to enhance serviceability and
increases uptime.
• User interface for access to configuration and alarm
information.
• Front panel pass-through to access a remote
3150 CSU.
• Front Panel Emulation via Windowst-based front
panel emulation software.
• Async terminal interface support.
• Front Panel Access Control Feature.
• SNMP management support.
Alarm Interface
The Model 3150 CSU can be attached, either locally or
remotely, to an ASCII terminal or printer to display/print
alarm messages. The COM and MODEM ports can be
used as destinations for Alarm Set and Alarm Clear
messages. This enables an ASCII terminal/printer or
Async terminal to be used to monitor the CSU for alarm
conditions, but provides a potential conflict if the COM or
MODEM port is also the current active physical interface.
If this occurs, the user interface functions have priority
over any alarm messages that are sent to the currently
active physical interface.
Alarms can also be displayed on a PC that is using a
terminal emulation package.
Integral Modem
The Model 3150 CSU contains an integral modem that
enables communication with remote devices such as
another 3100 Series CSU, or an ASCII terminal or printer.
This is a low-speed (2400 bps), V.22 bis dial modem that
provides remote dial-up capability to support
downloading, pass-through, alarm reporting, and remote
configuration and diagnostics. The integral modem can
also communicate with a PC running the 3100 Series
Front Panel Emulation software accompanying the
315x CSU.
User Interface
There are three ways of accessing the user interface:
• Front panel – provides an LCD and a keypad
which enable you to display information about and
interact with the CSU. A menu tree is available
which enables control of the CSU in the network
(see Appendix A, Front Panel Menu).
• COM Port – used for 315x Front Panel Emulation
software which displays the CSU front panel on a
PC and provides the same functions as the actual
front panel. It is also used for the async terminal
connection. For Model 3151 CSUs, only one slot in
the carrier can be configured as the COM port; all
slots share the PC.
1-2
• MODEM Port – provides 315x CSU functionality
from a PC attached either remotely or by using
pass-through via another CSU. It is also used for
the async terminal connection. This port is only
located on the Model 3150 CSU.
Model 3150 CSUs can be configured to generate traps
on alarms which can be sent to an SNMP manager via
either the MODEM or COM port.
Front Panel Emulation
The 315x CSU offers the same functionality through
Front Panel Emulation software as that provided by the
CSU front panel. The CSU can either be locally attached
to a 286 or higher PC, or remotely through a local Model
3150 CSU’s integral modem. A copy of the CSU front
panel appears on the PC; full functionality of the front
panel is available by clicking on the Function keys with
the mouse rather than by pressing these keys from the
actual front panel.
For 3151 CSUs, a single PC is used to access all of the
slots in the carrier. The PC is connected locally to a single
slot containing either a 3151 CSU or 3161 DSU/CSU that
has been configured as the master communication unit.
The master communication unit provides the shared COM
port on the Auxiliary Backplane, so that an attached PC
can access any 3151/3161 device attached to the Auxiliary
Backplane.
The 3151 CSU is capable of activating the shared
alarm relay on the 3000 Series Carrier, if so configured.
The alarm relay is deactivated when the condition causing
the alarm is corrected, or an Alarm Cut-Off (ACO)
command is issued from the SDCP or the optional Front
Panel Emulation software.

Chapter Title
Front Panel Pass-Through
Pass-through (passthrough) mode enables the user at
the local CSU to access the front panel of a remote
3150 CSU using the integral modem. In addition, front
panel pass-through can be used from a PC connected to
the COM port of the local Model 3150 CSU. By using
Pass-through mode, the user can operate the remote
3150 CSU through the front panel of the local CSU or via
the PC using the Front Panel Emulation software .
Async Terminal Interface Support
A Model 3150 CSU can be configured and managed
from an async (asynchronous) terminal. When the Async
terminal feature is enabled, the Model 3150 CSU can be
managed from the async terminal’s full screen display
using a menu hierarchy similar to, and the same option
selections available from, the CSU front panel. The async
terminal can be connected locally via the COM port for
direct access or connected via the modem port for dial-in
access.
Procedures throughout this manual are described
specifically for a front panel user. Look for the subhead
Differences Using the Async Terminal within each
procedure section for the user interface information on the
Async Terminal feature.
Front Panel Access Control Feature
Using the Front Panel Access Control feature, you can
disable the front panel so that users cannot manipulate
device configuration options from the front panel. This
feature is especially useful in conjunction with the async
terminal interface or front panel emulation on the PC.
SNMP Management Capabilities
The Model 3150 CSU supports the Simple Network
Management Protocol (SNMP), Version 1, and therefore
has the capability of being managed by any
industry-standard SNMP manager. The company provides
an SNMP application tailored for 3100 Series devices that
runs on a Hewlett-Packardr HP OpenView network
management platform. This application enhances your
ability to manage the 3100 Series devices by presenting
the Management Information Base (MIB) information
relevant to these devices in an easy-to-read format. The
3150-A2-GB22-10
functionality provided by the SNMP application is a
subset of the functionality available through the CSU’s
front panel. The 3100 Series SNMP application is used to
manage and control general device functions, the Network
T1 interface, the DSX-1 (DTE) interface, the
Communications (COM) interface, the MODEM
interface, and the individual DCE ports. For more
information about SNMP management of
3100 Series devices, refer to the ACCULINK 3100 Series
Open Management Application for HP OpenView User’s
Guide.
SNMP is an industry-standard network management
system that is used to monitor network performance and
status, and to report alarms (i.e., traps). To function,
SNMP requires a manager consisting of a software
program housed within a workstation; an agent consisting
of a software program housed within a device (e.g.,
3150 CSU); and a MIB consisting of a database of
managed objects, accessible to agents and controlled via
SNMP, to provide network management information.
The 3150 CSU supports a MIB that can be accessed
using SNMP protocol by external SNMP managers. The
following MIBs are supported:
• MIB II – Defines the general objects for use with a
network management protocol in TCP/IP internets
and provides general information about the CSU.
MIB II is backward-compatible with MIB I.
• DS1/E1 MIB – Defines objects for managing DS1
interfaces and supports the network and DTE
drop/insert T1 interfaces.
• RS-232-like MIB – Defines objects for managing
RS-232 type interfaces (e.g., RS-422, RS-423, etc.)
and supports management communication ports on
the CSU.
• Generic-Interface MIB Extensions – An extension
to MIB II that defines additional objects for control
of generic interfaces in MIB II. It supports control
of tests on the CSU’s T1 interfaces that are not
supported by other MIBs.
Two link layer protocols are supported for connection
to an external SNMP manager or network device,
Point-to-Point Protocol (PPP) and Serial Line Internet
Protocol (SLIP). The protocol type is configurable using
the configuration options (see Appendix C, Configuration
Options).

ACCULINK 3150 Channel Service Unit
Communication with the external SNMP management
system can be through a serial connection on either the
COM port or the MODEM port. Only one port can be
configured as the management link at one time. However,
the 3150 CSU can be accessed simultaneously by either
the front panel or Front Panel Emulation software on one
port, and an SNMP management system on the other port.
Users on the external SNMP manager can issue “Get” and
“Set” SNMP commands to an object in the SNMP
database maintained by the CSU. The CSU can be
configured to issue SNMP traps to the SNMP manager
under various alarm conditions.
Standalone Model 3150 CSU
The Model 3150 CSU is housed in a compact,
standalone unit containing a front panel for control and
monitoring of the CSU and a rear panel for connections.
The 3150 CSU front panel contains,
• One 2-line, 16-alphanumeric character per line
liquid crystal display (LCD)

In addition, a 3150 CSU, acting as an SNMP agent, can
be connected to and managed from an SNMP
management system in one of three ways:
• Serial connection via the COM or MODEM port to
an SNMP management system using either
Point-to-Point Protocol (PPP) or Serial Line
Internet Protocol (SLIP) (see Figure 2-5).
• Serial connection via the COM or MODEM port
(using PPP or SLIP) through a network device (e.g.,

The following procedure is offered for experienced
CSU users who are familiar with the 3150 CSU
installation process and have no special requirements for
their application.
Read and follow all warning notices and instructions
marked on the 315x CSU or included in this guide.
HANDLING PRECAUTIONS
FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect
sensitive components from damage
due to electrostatic discharge (ESD)
during normal operation. When
performing installation procedures,
however, take proper static control
precautions to prevent damage to
equipment. If you are not sure of the
proper static control precautions,
contact your nearest sales or service
representative.

Chapter Title
Power-Up Self-Test
After the 3150 CSU has been connected to a power
outlet, the power-up self-test is performed to ensure that
the unit is in good working order. The Model 3150 CSU
performs this test on itself upon power-up or after a device
reset unless it has been disabled by the Self-Test
configuration option (see Appendix C, Configuration
Options). The 3151 CSU performs the same power-up
self-test except that progress is not reported on the SDCP
during the test. However, you can use the Self-Test Health
command to display the status of the test (see Self-Test
Health section in Chapter 3, Operation).
The self-test includes a basic CPU test, a limited RAM
test, a code checksum test, and basic verification tests of
its internal components. The front panel LCD displays the
progress and pass/fail status of these power-up tests.
The power-up self-test consists of the following steps:
1. Once the CSU is plugged in, the In Progress
screen appears and the Fail LED blinks ON and
Off continuously.

about the results of the self-test, use the Self-Test
Health command to display the status of this test
(see Self-Test Health section in Chapter 3,
Operation).

2. All the LEDs then start to flash simultaneously in
the pattern twice ON, then Off. Then, the LCD
begins to flash characters and numbers in the same
pattern, alternating with the flashing LEDs.

Model 3150 CSU User
Interface Access Security
Level 2 (Lvl2) access security restricts access to only
those functions that cannot affect the operation of the
DSU/CSU in any way. At this level,
The user interface access security option allows you to
limit access to the 3150 CSU to display-only and
non-intrusive functions. The user access security option is
not available for 3151 CSUs.
Level 1 (Lvl1) access security allows access to all
functions available through the menu tree. This is the
default setting.
• None of the functions in the Test or Ctrl branches
are available.
• All functions on the Stat branch are available.
• All functions on the Cnfg branch are available for
display, but they cannot be used to save to a
configuration (Active, Cust, Fact1, or Fact2).
You can only reach the screen that controls security
access using the front panel; you cannot access this option
using front panel emulation, or the modem interface
(async terminal).
The procedure for changing user interface access
security levels appears on the following tear-out page.

Operating the Front Panel
NOTE
The Model 3150 CSU front panel (Figure 3-1) consists
of an LCD that displays messages, a keypad, 12 LEDs,
and six test jacks. The Model 3151 CSU faceplate
contains these same 12 LEDs and six test jacks (see
Figure 3-2), however, the LCD and keypad are located on
the SDCP of the 3000 Series Carrier (see Figure 3-3). A
description of the front panel is contained in Chapter 1,
Introduction. Instructions for operating the front panel for
the Model 3150 CSU are listed below. The Model 3151
CSU faceplate and the carrier’s SDCP operate in the same
manner, except where noted.
A graphical representation of the
315x CSU front panel can be
displayed on an attached PC. You
can also use the Async Terminal
feature which provides full screen
displays for managing and
configuring a 315x CSU from an
attached async terminal.
Differences in front panel
operation for Front Panel
Emulation and async terminal are
noted where applicable. Front
Panel Emulation is further
described in the Front Panel
Emulation on a PC section later in
this chapter. The Async Terminal
feature is described in the Using
the Async Terminal Feature
section later in this chapter.

Context-Sensitive Menu
The LCD displays messages and the front panel menu
in an easy-to-read English format, including
easily-recognizable abbreviations and symbols
(Figure 3-4).
This CSU is an intelligent device that displays only
those options that are valid for the current configuration.
Therefore, you will only be presented with menu choices
that are consistent with the current configuration and
operational state of the CSU; invalid combinations of
configuration options are not displayed. Although all
options are shown in this manual, what you see on your
CSU varies with your configuration.

groups according to whether they are monitoring system
conditions (the CSU itself), conditions on the network
interface, or conditions on the DTE interface. A green
LED indicates normal operation. A yellow LED indicates
a warning. Conditions are sampled every tenth of a
second.

Operation
Front Panel Emulation on a PC
The 315x CSU front panel can be mimicked on an
attached PC. This front panel emulation capability allows
you to access the Model 3150 CSU (local or remote)
through a PC connected to the COM or MODEM port.
For Model 3151 CSUs, only one slot in the carrier can be
configured as the COM port to provide access for a PC.
This slot provides access to all of the circuit cards in the
carrier.
Use the front panel display (Figure 3-8) to control the
CSU from a PC just as though you are operating from the
CSU’s own front panel. The PC window is updated every
five seconds to show the current state of the CSU.

NOTE
When you use front panel
emulation on a PC, you can
execute all front panel commands
except those for the User
Interface Access Security (for
Model 3150 CSUs) and the Lamp

Configuring the CSU
You have the option of customizing your 315x CSU for
optimum performance in your network. Customization is
achieved through the CSU’s configuration options.
Configuration Option Areas
The 315x CSU offers four sets of configuration options
located in the following areas:
• Active (Activ). The configuration option set that is
currently active for the CSU is stored here. Before a
set of configuration options become active for the
CSU, the set must be saved to the Active area.
When the CSU is shipped from the factory, the
Active configuration option set is identical to both
the Customer and the Factory 1 sets. This area can
be written to and controls the current operation of
the device.
• Customer (Cust). The set of customer-defined
configuration options. Customer set is identical to
the Factory 1 set when the CSU is shipped from the
factory. This area can be written to.
3-12
• Factory 1 (Fact1). A set of configuration options
that have been preset at the company. This set is
determined by what is considered to be the most
common configuration used in the CSU market.
Factory 1 options are read-only.
• Factory 2 (Fact2). A set of configuration options
that have been preset at the company. This set is
determined by what is considered to be the second
most common configuration used in the CSU
market. Factory 2 options are read-only.
Configuration Options
The configuration options are divided into four
functional groups, depending on whether the option
affects the DTE interface, network interface, user
interface, alarms, or SNMP. Appendix C contains a list of
the configuration options and the Factory 1 and Factory 2
defaults.
Configuration Procedures
The Configuration (Cnfig) branch of the CSU front
panel menu tree is used to display or change CSU
configuration options (see Figure 3-13).

Selecting the Port
The 3150 CSU supports a communications link
between the CSU and an external SNMP management
system or network device (e.g., router) on either the COM
port or the MODEM port. Use the MODEM port when
configuring devices through a dial-up modem. Use the
COM port for direct connections. Either the COM or the
MODEM port can be configured as the communications
link, but only one port at a time can be configured as the
link. The MODEM port can support either synchronous or
asynchronous PPP, or asynchronous SLIP at data rates of
up to 2400 bps. The COM port can support either
synchronous or asynchronous PPP, or asynchronous SLIP
at data rates of up to 19,200 bps.

The IP address is the address used by the SNMP
manager to access the device. For devices using PPP, the
IP address can be negotiated, if the network device, e.g.,
router or SNMP manager, supports such negotiation. The
IP address is composed of four fields with three digits per
field (xxx.xxx.xxx.xxx).
The IP address is set for either the COM port or the
MODEM port, depending on which one has been chosen
as the SNMP communications link. The example below
assumes that an IP address of 010.155.111.222 is being set

A trap is an unsolicited message that is sent from the
CSU to an SNMP manager when the device detects
certain, prespecified conditions. These traps enable the
SNMP manager to gauge the state of the network. The
SNMP Trap Enable configuration option must be enabled
for trap messages to be sent over the communications
link. You must specify the number of SNMP managers
that are to receive traps from this device, an IP address for
each SNMP manager specified, and the type of traps to be
sent from this device. See Appendix C, Configuration
Options for more information about how to set these traps.
Trap types consist of the following:
F1
F2
• General traps – include “warmStart” and
“authenticationFailure”. The device sends a
warmStart trap after it has been reset to indicate
that it has just reinitialized itself. The device sends
an authenticationFailure trap when it has received
an SNMP protocol message that has not been
properly authenticated. These traps are set by the
Gen Trap configuration option.

• Enterprise Specific traps – signify that the device
has recognized an enterprise-specific event. See
Table 3-6 for enterprise-specific traps. These traps
are set by the Entp Trap configuration option.
F3
12. Press F2 (Read) or F3 (R/W). The Read selection
allows read-only access (SNMP “Get”) to the
accessible objects in the MIB when community
name 1 is used. The R/W selection allows
Read/Write access (SNMP “Get” and “Set”) to the
objects in the MIB. Write access is allowed for all
objects specified as read/write in the MIB. Read
access is allowed for all objects specified as
read-only or read/write.

• Link Traps – identify the condition of the
communications interface, either linkDown (one of
the communications interfaces has failed) or linkUp
(one of the communications interfaces has just
come up). These traps are set by the Link Trap
configuration option. The communications
interfaces for which these traps can be generated
are specified by the Trap I/F configuration option.

Communication between the Model 3151 CSUs in the
3000 Series Carrier and an external PC (attached either
locally or through an external modem) occurs through a
shared communication (COM) port (refer to the
COMSPHERE 3000 Series Carrier Installation Manual
for cabling information). Unlike standalone Model 3150
CSUs, the Model 3151 CSUs do not have a dedicated
COM port for external access. Therefore, one circuit card
in the carrier must be selected as the Master
Communication Unit, which provides the COM port for
all circuit cards in the carrier. Once configured as such,
the Master Communication Unit differs from others in the
carrier because it now has COM port configuration
options that can be selected. These options are used to
configure Port 2 on the Auxiliary Backplane as the COM
port for the carrier.

Device Health and Status
Checking the Status of
the CSU
You can request various types of information from the
CSU front panel to tell you the status of the 315x CSU.
This information is accessed from the Status branch of the
front panel menu tree (see Figure 3-22).
Use the Device Health and Status branch to view
current health and status information of the CSU. One or
more status messages will display in priority order
(highest to lowest) on line 2 of the LCD when this menu
branch is accessed. On the front panel, use the scroll keys
to view any additional messages. Table 3-7 contains a list
of these messages in priority order (highest to lowest).
The CSU is polled for current status every ten seconds.
If the status has changed from the last poll, the Health and
Status screen currently displayed will be updated and
return to the beginning (that is, the highest priority
message will be redisplayed). The message CSU
Operational appears when there are no other messages.
Differences Using the Async Terminal: To allow you to
display health and status information from one screen,
select Health, Test Status, and Self Test Results from the
main/status menu. Figure 2-10 in Chapter 2 shows an
example of this results screen.

Performance Report
Network performance is continuously monitored and
maintained in internal memory registers when the network
interface is configured for ESF operation. The CSU
maintains two sets of registers, Carrier Network Interface
Registers (Telco) and User Network Interface Registers
(User). The User registers contain an extra status register
(Status Event). The User registers can be reset from the
CSU front panel via the Clear command in the Control
branch of the front panel menu. The Telco registers can
only be reset via a command from the network (refer to
AT&T TR 54016).
The registers are a set of accumulators or status
registers that collect performance data for the previous
24-hour period. Registers shown on the front panel LCD
are listed in Table 3-9. This data is updated in 15-minute
intervals. After 15 minutes, the current interval is rolled
over into a set of registers that represent the previous 96
15-minute intervals for the register. An interval total of
how many of the 96 registers contain valid data is also
kept, as well as a 24-hour total for each accumulator
register. The relationship of the registers is shown in
Figure 3-24.

Acquiring/Releasing the Active Physical
Interface
Controlling the CSU
The Control branch of the front panel menu tree allows
you to control various aspects of the user interface and
integral modem. Figure 3-27 shows the Control branch.
You can access a user interface from either the front
panel, the SDCP (for Model 3151 CSUs only), the
MODEM port (for Model 3150 CSUs only), or the COM
port. The 315x CSU allows only one physical interface to
be active at any one time. The front panel is the default
user interface; that is, at power-up, after a reset, during a
software download, and after a failure at either the local or
remote PC, or async terminal.
If the front panel is disabled, after self-test the active
physical interface defaults to the COM port (if configured
for a user interface) or the MODEM port. During
download, the front panel always displays Status.
You can switch an inactive physical interface to be the
active physical interface provided, if one of the following
is true:
• The current active physical interface has had no
activity (no key was pressed) for at least the past
five minutes.
• The active physical interface has been released with
the Release command.
• The active interface connection is broken. This
includes the call disconnect for a modem interface
or the termination of the front panel emulation
program on a locally attached PC (if PC supports
DTR) or the termination of the async terminal
interface on a remote or locally attached terminal.

Using the Integral Modem
The Model 3150 CSU features an integral modem
which enables your CSU to communicate with remote
devices to display alarm messages or to function as the
user interface. The integral modem also enables you to
initiate a pass-through connection to a far-end CSU. For
more information on these configurations, refer to
Chapter 2, Installation. The Model 3151 CSU does not
have an integral modem.
The Call command, available from the Control branch
of the menu tree, provides the following functions that are
necessary to initiate and terminate modem connections:
• Pass – to set up a call through the integral modem
and initiate a front panel pass-through session.
• Dial – to set up a call through the integral modem
for ASCII terminal/printer or PC connection.
• Disconnect – to disconnect an active modem
connection.
• Change Directory – to enter phone numbers into
the internal phone directories.

Using the Async Terminal
Feature
You can use an async terminal to manage the 3150
CSU devices from either the COM port or MODEM port.
You can perform device management and configuration
operations as if using the device’s front panel without the
limitation of the 2-line, 16-character LCD. An entire
menu, submenu, test result, or all configuration selections
for a configuration option appear on a single screen
display.
This section is provided as a supplement to all the
procedures described throughout this manual for using the
front panel. Therefore, all the procedures, tables and
descriptions of fields and input values provided in all
chapters and appendices apply to the information
displayed on the async terminal screens. There are
differences in menu selections made from the front
panel/PC interface and the async terminal interface when
performing a task. Refer to the Differences Using the
Async Terminal Interface heading within each procedure
description to note the differences between interfaces.
This section is limited to describing how the async
terminal feature is configured, how it is accessed and how
to navigate among the menus and screens.
Setting Interface Options
5. Choose either a Local (for near-end CSU) or
Remote (for far-end CSU) destination.
Certain user interface options must be set to enable
async terminal operation. Using the front panel, use the
Configuration (Cnfig) branch of the front panel menu
hierarchy to edit the User Interface (User) options for
async terminal operation. Table 3-11 shows the
configuration options and appropriate settings for the
Async Terminal feature. Basically, the change depends on
the port supplying the connection. The other configuration
options use their defaults but they should be verified.
6. If you chose a Local destination, click on the
Execute button. If you chose a Remote
destination, enter the telephone number of the
far-end CSU in the Phone Number field, then

automatically display the top-level menu provided a
password is not required.
If access security is required, the Password Access
screen displays the prompt for password input. If access
security is not required, the top-level menu (or main
menu) appears or a message appears indicating that
another user has control of the device. In this case, the
screen shows which type of connection is active, Ft.

Entering a Password
When access security is required, the Password Access
Screen appears and the password must be entered.
• If the password is valid, the CSU’s top-level menu
is displayed.
• If the password is invalid, an invalid password
message displays and the Password Access Screen
redisplays and waits for password reentry.
When password verification is enabled on a port, the
password must be entered and validated before any other
action occurs. Password verification is independent of the
port state (active, inactive, idle).

Async Terminal Menus and Screens
Menus differ from the front panel in that they typically
do not use abbreviations and in some cases provide a
more direct access to an option or function. However, the
menu selections are straightforward and the logical
grouping of the menu tree remains the same between
interfaces. In general, the interfaces follow the same
paths. A few options available from the 3150 CSU front
panel are not available from the async terminal interface,
such as the Lamp test. This is noted where appropriate in
the procedures. The async terminal interface also supports
the same context sensitivity as the front panel.
The top line of every screen always the menu path for
the function (or configuration option) being displayed.
The second line shows the customer identification (CID)
number and the CSU’s model number. The remaining
screen area is used for menu or option-specific
information.

Operation
There are three screen types: menu selection, edit and

through the menu system, edit screens provide the
interface for changing configuration options, and display
screens provide configuration information and results
from performance and device specific tests. Unlike the
front panel operation where you constantly key forward to
view or choose configuration options and selections, the
Async Terminal feature displays all selections for a menu
or configuration option in full screen format with
functions available to operate on the screen information
appearing at the bottom of the screen.

Editing: Edit screens allow you to edit or change
information on a screen. Basically, the procedure for
editing or changing options using an async terminal is the
same as the front panel. However, you must take into
account the full screen capability which makes

Operation
Displaying Information: Display screens show results
from a data collection operation such as performance or
device test. They also can simply display configuration
information such the Identity screen. These screens cannot
be edited. Data or status continues to be collected while
the screen is displayed. Status and performance polling
occurs at regular intervals. Selecting Refresh updates the
screen display with the most current information.
Typically, display screens are filtered to show only the
information or data collected for the active configuration.
Character Matching: The async terminal also supports
character matching for entering valid values in fields

Overview
Alarms
The ACCULINK 315x CSU is capable of detecting
and reporting faults, performing diagnostic tests, and
downloading software. These features are provided to
ensure that your CSU is giving you optimum performance
in your network.
The 315x CSU monitors alarm conditions occurring on
either the network interface or the DTE interface. For
Model 3150 CSUs, these alarms can be routed to the
MODEM port, the COM port, or both. Each alarm is
preceded by the customer identification so that you know
which CSU is having the problem. Possible alarm
messages are as follows where x is the DTE or Network
interface, depending on where the condition was detected.
Troubleshooting
The CSU offers a number of front panel alarms to alert
you to possible problems. Once problems are detected,
you can use the troubleshooting table provided
(Appendix F) to decide what action to take. Also refer to
the Test Commands section later in this chapter to isolate
problems via loopback tests and test patterns. A Lamp test
is also provided.

For Model 3151 CSUs, these alarms activate the alarm
relay, if so configured.

If two alarm conditions are detected at once, the higher
priority alarm is reported. However, if an even higher
priority alarm is detected before the first alarm is cleared,
the later alarm is not reported. Alarms remain active until
the alarm condition is cleared. Also, an alarm clear
message is reported, unless another alarm occurs right
away. In this case, the alarm report takes precedence over
the alarm clear message.
SNMP Traps
If you are using SNMP to manage your 3150 CSU,
link-up and link-down traps are generated when the state
of an interface changes. A link-down trap is generated
when an interface transitions from an up state to a down
state. A link-up trap is generated when an interface
transitions from a down state to an up state. Table 4-1
defines traps for each interface.

Test Commands
The test commands enable you to run loopbacks and
test patterns on the CSU, and to test the front panel LEDs.
These tests can help you isolate areas of trouble in case
you are having problems with your 315x CSU. All Test
commands are accessed from the Test branch of the front
panel menu tree (see Figure 4-1).
Figure 4-2. Test Branch for Async Terminal
All the local loopback tests are mutually exclusive with
the send pattern and remote loopback tests. If you attempt
to run a test that is already active or an invalid local
loopback test combination (see Table 4-2), an error
message is displayed.
The Lamp test is not available from the async terminal
interface.
Remote Loopback Test Commands
The Remote Loopback tests allow you to send Line
Loop Up (LLBUP) and Line Loop Down (LLBDN) codes
on the network interface. These commands allow you to
place a far-end CSU in and out of loopback to
troubleshoot your circuit.
Remote loopbacks cannot be performed if any of the
local loopbacks are currently active. If you attempt to do
so, the error message Invalid Test Combo appears.
Figure 4-1. Test Branch
To send a Line Loop Up code up the network to the
far-end CSU,
Differences Using the Async Terminal: For the async
terminal interface, the Test branch differs from the front
panel Test branch in both organization and selection. The
async terminal’s full-screen display organizes the test
selections into tests run on the T1 interface, as shown in
Figure 4-2.

Local Loopback Test Commands
The local loopback tests enable you to conduct circuit
testing and single-ended fault isolation for the digital line.
The four local loopback tests supported are Line
Loopback (LLB), Payload Loopback (PLB), DTE
Loopback (DLB), and Repeater Loopback (RLB). The
Line Loopback and Payload Loopback commands can be
activated and deactivated in response to commands
received over the network interface as specified by ANSI
and AT&T standards. The Network Interface
configuration options NET LLB and NET PLB control
whether the CSU responds to the commands transmitted
on the network interface (see Appendix C, Configuration
Options). Local loopback tests can be aborted (Abort
Command) at any time.
No more than two local loopbacks can be active at any
one time. An additional restriction exists that prohibits
certain loopbacks from running at the same time. Valid
loopback combinations listed in Table 4-2 are identified
by YES.

• SNMP Configuration Options
Functional Grouping
The 315x CSU configuration option tables contain a
list of all configuration options and their selections for a
functional group within the front panel menu. The
configuration options are arranged into four functional
groups:
• DTE Interface Configuration Options
The DTE Interface Configuration options configure
the DTE interface of the 315x CSU (Table C-1).
SNMP Configuration Options configure the 3150
CSU to be managed using SNMP (Tables C-5 and
C-6).
The configuration tables include a description of each
configuration function and its selectable options. In the
tables, the top line of each configuration option entry
indicates the factory default setting. When the Factory 1
default differs from the Factory 2 default, the Factory 1
default is listed first and both defaults are clearly marked.
• Network Interface Configuration Options
Network Interface Configuration options configure
the Network Interface of the 315x CSU
(Table C-2).
• User Interface Configuration Options
User Interface Configuration options configure and
control the 315x CSU User Interfaces (Table C-3).
• Alarm Configuration Options
Alarm Configuration options specify how alarm
conditions are handled by the Model 315x CSU
(Table C-4).
3150-A2-GB22-10
Context-Sensitive Menu
This CSU is an intelligent device that displays only
those options that are valid for the current configuration.
Therefore, you will only be presented with menu choices
that are consistent with the current configuration and
operational state of the CSU; invalid combinations of
configuration options are not displayed. Although all
options are shown in this manual, what you see on your
CSU varies with your configuration.

Alarm Messages. Controls the generation and routing of alarm messages to an ASCII terminal/printer attached to either
the MODEM or COM port. An alarm message generates at the beginning of an alarm state and is followed by an alarm
clear message. Only one alarm state can exist at any one time. When two or more alarm conditions exist, the highest
priority alarm state is declared. Alarm state priority, from highest to lowest, is LOS, LOF, AIS, OOF, EER, yellow alarm.
Alarm messages consist of a customer identification flag, Alarm Set or Alarm Clear, the alarm condition, and the interface
at which the alarm has been detected.
Disab – Prevents an alarm message for any alarm conditions.
Modem – Enables alarm messages routed to the MODEM port (and sent if the MODEM port is not the active physical
interface).
Com – Enables alarm messages routed to the COM port (and sent if the COM port is not the active physical interface).
Both – Enables alarm messages routed to both the MODEM and the COM ports.
NOTE: Alarm messages are only sent to a particular port if the port is currently configured for proprietary ASCII or Term,
if the async terminal is idle. If the SNMP management link is active for the port, the alarm message for that port
is discarded. Refer to Chapter 4, Maintenance, for more information about alarm messages.
NOTE: This configuration option is not displayed on Model 3151 CSUs.

Alarm Dial Out. Controls whether alarm or trap messages sent to the MODEM port initiate a call (to the phone number in
Directory A) if the modem connection has not already been established. If the Call Retry configuration option is enabled,
the alarm message is held until the call is completed or a maximum of five retries have occurred. If more than one
message is received while waiting for a call retry, only the highest priority message is held and all others are discarded.
When the modem port is configured as the SNMP management link, up to ten SNMP trap messages are queued at the
interface.
Enab – Permits automatic call initiation (dial out) on the MODEM port when an alarm message must be sent.
Disab – Discards messages sent to the MODEM port if a modem connection has not been established.

Group
Not supported since this group is
not supported in MIB II.
The objects defined by MIB II are organized into 10
different groups. The DSU/CSU implements only those
groups where the semantics of the group are applicable to
the implementation of a DSU/CSU (e.g., if EGP is not
implemented, the EGP group is not supported). The MIB
II object groups supported or not supported by the 3100
Series devices are as follows:
IP Group
Supported on the interface
(MODEM or COM) configured as
the SNMP management link.
ICMP Group
Supported on the interface
(MODEM or COM) configured as
the SNMP management link.
TCP Group
Not supported since the TCP
protocol is not supported by the
DSU/CSU.
UDP Group
Supported on the interface
(MODEM or COM) configured as
the SNMP management link.
EGP Group
Not supported since the EGP
protocol is not supported by the
DSU/CSU.

Interface Group, MIB II
Interface Group – “ifType” Object (ifEntry 3)
The interfaces group consists of an object indicating
the number of interfaces supported by the unit and an
interface table containing an entry for each interface. The
T1 CSU provides an entry in the interface table for the
Network T1 interface, the DTE Drop/Insert T1 interface,
the COM port, and the MODEM port. The following
sections provide clarification for objects contained in the
Interface Group where it is not clear how the object
definition in MIB II is related to the CSU.
This object identifies the type of the interface based on
the physical/link protocol(s) immediately below the
network layer. Only the following values are supported by
the CSU:
This object provides the textual information about the
interface. Set each interface to a text string as specified
below:

Modem:
The currently configured data rate
for the port.
3150-A2-GB22-10
SNMP MIB Objects
Interface Group – “ifAdminStatus” Object
(ifEntry 7)
This object specifies the desired state (configuration)
of the interface. This object is supported only for the
MODEM port. It provides the ability to switch between
using the MODEM port as the SNMP management link
and ASCII operations (Dial-out, FPE). Refer to the 3100
Series device document for more information. The value
of this object will not affect the state of any of the
interfaces on the T1 CSU other than the MODEM port.
Only the following values are supported by the CSU:
• up(1) – The SNMP management link is active on
the MODEM port (i.e., the Modem Use
configuration option is set to SNMP).
• testing(3) – The SNMP management link is inactive
on the MODEM port and can be used for
proprietary ASCII functions.
• Interface Group – “ifOperStatus”
Object (ifEntry 8)
The interface is up(1) when no
alarm conditions exist.
The interface is down(2) when an
alarm condition is active.
DTE
The interface is up(1) when no
Drop/Insert T1: alarm conditions exist and the I/F
is enabled.
The interface is down(2) when an
alarm condition is active and the
I/F is disabled.
The interface is testing(3) when a
test is active on the interface.
3150-A2-GB22-10
When configured as the SNMP
management link, up and down are
based on the current state of the
link layer protocol. Otherwise, the
interface is always up(1).
The interface is never in the
testing(3) state.
MODEM Port:
When configured as the SNMP
management link, up and down are
based on the current state of the
link layer protocol. Otherwise, the
interface is always up(1) when the
MODEM is connected and
down(2) when the MODEM is not
connected.
The interface is never in the
testing(3) state.
Interface Group – Input Counters (objects
ifEntry 10 to ifEntry 15)
This object specifies the current operational state of the
interface. The value of this object for each interface is
defined as follows:
Network T1:
COM Port:
The objects used to collect statistics on the data
received by an interface apply only to the COM port and
the MODEM port when the port is configured as the
SNMP management link. For interfaces that are not
configured as the SNMP management link, these statistics
are not provided and an error status is returned if access is
attempted. The objects used to collect input statistics are
listed below:
• ifInOctets (ifEntry 10)
• ifInUcastPkts (ifEntry 11)
• ifInNUcastPkts (ifEntry 12)

Far End Group, DS1/E1 MIB
The DS1 Far End Group consists of the following three
tables:
Operational Note: The fractional T1 group only allows
specification of an entire interface to a particular time slot
on another interface (i.e., a time slot on one interface
cannot be mapped to a time slot on another interface).
This prevents complete mapping of time slots on the DTE
Drop/Insert T1 interface to time slots on the network T1
interface. For mapping time slots between the network
and DTE T1 interfaces the following convention will be
used. Time slots on the T1 interface that are mapped to
another T1 interface (i.e., not a data port) will be
connected in ascending order. For example, if the
fractional table for the network T1 interface maps time
slots 1, 3 and 5 to the DTE T1 interface and the DTE T1
interface maps time slots 10, 11 and 15 to the network the
following time slots will be connected: N1 – D10, N3 –
D11, and N5 to D15.
RS-232-like MIB (RFC 1317)
The “rs232” object defined by RFC 1317 is supported
for all of the synchronous DCE data ports, the MODEM
port, and the COM port. The RS-232-like MIB consists of
one object and five tables, as follows:
• Number of RS-232-like ports
• The General Port Table
• DS1 Far End Current
• The Asynchronous Port Table
• DS1 Far End Interval
• The Synchronous Port Table
• DS1 Far End Total
• The Input Signal Table
These tables are not supported for either the network or
DTE Drop/Insert T1 interfaces.
The DS1 Fractional Group, DS1/E1 MIB
The DS1 Fractional Group consists of the DS1
fractional table. This table (dsx1FracTable) is not
supported by the 3150 CSU. This table is fully supported
by the T1 DSU/CSU and allows channel (time slots) to be
mapped between the T1 interface and data ports. If an
invalid channel map (e.g. two interfaces mapped to a
single time slot, one interface mapped to two T1s, etc.) is
received an error will be returned to the SNMP manager.
The T1 DSU/CSU validates all channel configurations
before applying them.
