Government Requirements and Equipment Return
Certain governments require that instructions pertaining to DSU/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 3160/3164
DSU/CSU, and on the 3161 DSU/CSU 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 DSU/CSU can be configured to support any of the
following framing format and line signaling techniques. The DSU/CSU configuration must
correspond to the T1 line’s parameters. The 3160/3164 DSU/CSU 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 3161 DSU/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 316x DSU/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

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.

Introduction
Procedures throughout this manual are described
Front Panel Emulation
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.
The 3160/3164 DSU/CSU offers the same functionality
through Front Panel Emulation software as that provided
by the DSU/CSU front panel. The DSU/CSU can either be
locally attached to a 286 or higher PC, or remotely
through a local 3160/3164 DSU/CSU’s integral modem. A
copy of the DSU/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
keys from the actual front panel.
DSX-1 Drop/Insert Port
The DSX-1 Drop/Insert port allows DTEs/PBXs that
support the DS1 signal format to share the
T1 network with other high-speed equipment.
For 3161 DSU/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
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.
Backplane, so that an attached PC can access any
3151/3161 device attached to the Auxiliary Backplane.
The 3161 DSU/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.
SNMP Management Capabilities
The Model 3160/3164 DSU/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
functionality provided by the SNMP application is a
subset of the functionality available through the
DSU/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.
Front Panel Pass-Through
Pass-through (passthrough) mode enables the user at
the local DSU/CSU to access the front panel of a remote
316x DSU/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 3160/3164 DSU/CSU. By using Pass-through
mode, the user can operate the remote 316x DSU/CSU
through the front panel of the local DSU/CSU or via the
PC using the Front Panel Emulation software.
Async Terminal Interface Support
A Model 3160/3164 DSU/CSU can be configured and
managed from an async (asynchronous) terminal. When
the Async Terminal feature is enabled, the DSU/CSU is
managed from the async terminal’s full screen display
using a menu hierarchy similar to, and the same option
selections available from, the DSU/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.

ACCULINK 316x DSU/CSU
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.,
3160/3164 DSU/CSU); and a MIB consisting of a
database of managed objects, accessible to agents and
controlled via SNMP, to provide network management
information.
ACCULINK 316x DSU/CSU
Physical Description
The ACCULINK 316x DSU/CSU series of products
consists of a standalone 2-port Model 3160 DSU/CSU, a
standalone 4-port Model 3164 DSU/CSU and a 2-port
carrier-mounted Model 3161 DSU/CSU.
Standalone Model 3160/3164 DSU/CSUs
The 3160/3164 DSU/CSU supports a MIB that can be
accessed using SNMP protocol by external SNMP
managers. The following MIBs are supported:
The 3160/3164 DSU/CSUs are housed in a compact,
standalone unit containing a front panel for control and
monitoring of the DSU/CSU and a rear panel for
connections. This standalone unit can be mounted on a
wall, an equipment shelf, or an RS-310-C equipment
cabinet with the optional wall-mount kit.
•
MIB II – Defines the general objects for use with a
network management protocol in TCP/IP internets
and provides general information about the
DSU/CSU. MIB II is backward-compatible with
MIB I.
3160/3164 DSU/CSU Front Panel
•
•
DS1/E1 MIB – Defines objects for managing DS1
interfaces and supports the network and DTE
drop/insert T1 interfaces.
The 3160/3164 DSU/CSU front panel contains,
•
•
•
One 2-line, 16-alphanumeric character per line
liquid crystal display (LCD)
RS-232-like MIB – Defines objects for managing
RS-232 type interfaces (e.g., RS-422, RS-423, etc.)
and supports synchronous data ports and
management communication ports on the
DSU/CSU.
One 7-button keypad (three Function and four
directional keys)
Twelve light-emitting diodes (LEDs), five of which
are shared between the DSX-1 (DTE) Drop/Insert
T1 interface and the data ports.
•
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 DSU/CSU’s T1 and synchronous
data interfaces that are not supported by other
MIBs.
•
Six test jacks
The front panel is shown in Figure 1-1.
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).
3160/3164 DSU/CSU Rear Panel
The 3160/3164 DSU/CSU rear panel contains the
connectors required for the operation of the DSU/CSU
(Figures 1-3 and 1-4). The connectors and their functions
are listed in Table 1-1.
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 3160/3164 DSU/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 DSU/CSU. The
DSU/CSU can be configured to issue SNMP traps to the

Establishing Access Security
on a Port
Although the password feature is available, it is not
required as a factory default. If used, it ensures access
security before device control is passed to a PC or
terminal connected to a port. The password configuration
option can be individually set for the COM or MODEM
port, or both if security is needed on both port types. The
default is none. From the front panel, set this
configuration option using the Control branch. Select
cnfig→edit→user→password. The password itself is set
separately. Refer to the section Setting/Changing a
Password.
Setting/Changing a Password
For 3160/3164 DSU/CSUs, you have the option of
setting a password for security when receiving a call or
the COM port connection is established. Unless you
specify otherwise, the password is null.

Operation
Operating the Front Panel
NOTE
The 3160 DSU/CSU front panel (Figure 3-1) consists
of an LCD that displays messages, a keypad, 12 LEDs,
and six test jacks. The Model 3161 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 3160/3164 DSU/CSU are listed below. The 3161
DSU/CSU faceplate and the carrier’s SDCP operate in the
same manner, except where noted.
You can display a graphical
representation of the 316x
DSU/CSU front panel on an
attached PC. You can also use
the Async Terminal feature which
provides full screen displays for
managing and configuring 316x
DSU/CSUs from an attached
async terminal. Differences in
operation between the front panel
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 section, Using
the Async Terminal Feature, also
later in this chapter.

Operation
LCD
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 DSU/CSU is an intelligent device that displays
only valid options for the current configuration.
Therefore, you are only presented with menu choices that
are consistent with the current configuration and
operational state of the DSU/CSU; invalid combinations
of configuration options do not appear. For example,
menus displayed for the Model 3160 (2 ports) and the
Model 3164 (4 ports) differ due to the number of ports
available. Also, if the DSX-1 Drop/Insert T1 interface
selection is disabled, many of the menu choices do not
appear. Be aware that although all options are shown in
this manual, what you see on your DSU/CSU varies with
your configuration.

Device Health and Status Messages
The 316x DSU/CSU features status messages that
appear on the front panel LCD. You can request device
health and status via the Device Health and Status branch
of the front panel menu (see the Device Health and Status
section later in this chapter). In addition, the highest level
status message appears on the front panel automatically if
no front panel action has occurred at the DSU/CSU for the
past five minutes.

Selecting the Port
Differences Using the Async Terminal: When SNMP is
selected from the main/configuration/edit menu, the menu
selection structure changes slightly from the front panel.
Specifically, the Gen selection (from the front panel) is
split into two logical groups: System Options and
Modem and Communication Port Options. Trap (from
the front panel) appears as Trap Options on the async
terminal interface. (See Figures 3-14 and 3-15)
The 3160/3164 DSU/CSU supports a communications
link between the DSU/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.
In the SNMP System Options screen as shown in
Figure 3-20, a maximum of 40 characters can be entered
per field. If more than 40 characters are required, then
scrolling on the line is supported. To scroll, move the
cursor to the end of the line. To clear a field, select Clear.
This action sets the field to a null string, A message
appears requiring you to verify that a clear is intended.
After executing Clear, the cursor is located at the
beginning of the cleared field.

SNMP Traps
A
trap is an unsolicited message that is sent from the
DSU/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.

For the 3164 DSU/CSU, there is a
hardware limitation that limits the
combined bandwidth used by
Port1 and Port3 to a total of
2048 kbps, and the combined
bandwidth used by Port2 and
Port4 to 2048 kbps. Thus, the rate
choices shall be limited
Block – Allows a block of contiguous channels to be
assigned by specifying a data port rate and a starting DS0
channel. The number of channels assigned is determined
by the port rate. Only those DS0 channel numbers that
provide enough bandwidth (based on the port’s data rate)
to be used as a starting channel number are displayed on
the screen. These channels are automatically assigned to
the destination T1 interface when the block method is
used and the starting channel is selected.
appropriately due to this
constraint. This limitation should
only occur in configurations
mapping a port to a port or when
mapping ports to the DSX-1 and
to the network.
ACAMI – Allows a block of contiguous channels to be
assigned by specifying a data port rate and a starting DS0
channel. However, with ACAMI, the number of channels
assigned is twice the number needed for the port rate. This
is because with ACAMI, every alternate DS0 channel
(starting with the n+1 DS0 channel), does not carry data
from the port, but instead always transmits and receives
all ones.

Timing
NOTE
The 316x DSU/CSU provides the ability to select a
master clock (timing) source that is used to synchronize
all of the T1 and data port interfaces on the DSU/CSU.
When a master clock source is selected, the DSU/CSU
will synchronize to the master clock and derive clocking
for all of the interfaces on the DSU/CSU. The clock for
each interface will be at the appropriate rate for that
interface (e.g., 1.544 Mbps for the T1 interfaces, the
configured port rate for the data ports) and independent of
the master clock rate. This means that the master clock
rate and the DSU/CSU interface rates may be different.
The DSU/CSU will automatically fall back to the internal
master clock when a failure of the selected master clock is
detected.
For Model 3161 DSU/CSUs, the
external clock provides timing for
up to eight slots in the carrier.
Each Auxiliary Backplane must
have its own external clock input.
The DSU/CSU clock source configuration option
enables you to select one of five sources for the master
clock, either the Network T1 interface, the DSX-1
Drop/Insert T1 interface, Port 1, internal clock, or external
clock. If external clocking is selected, you must use the
clock rate configuration option to specify the clock rate.
Two examples for configuring timing are given below. For
more information on the configuration options, refer to
Appendix C. Figure 3-32 shows some common clocking
configurations.

Communication between the Model 3161 DSU/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 Models
3160/3164 DSU/CSUs, the Model 3161 DSU/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 circuit cards 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.

Checking the Status of the
DSU/CSU
You can request various types of status information
from the 316x DSU/CSU’s front panel. Access this
information from the Status branch of the front panel
menu tree (see Figure 3-33).
Figure 3-34. Async Terminal Status Branch
Device Health and Status
Use the Device Health and Status branch to view
current health and status information of the DSU/CSU.
When you access this branch, one or more status messages
display in priority order (highest to lowest) on Line 2 of
the LCD. On the front panel, use the scroll keys to view
any additional messages. Table 3-9 lists these messages in
priority order.
The DSU/CSU is polled for current status every ten
seconds. If the status has changed from the last poll, the
Health and Status screen is updated and the highest
priority message is redisplayed. The message DSU/CSU
Operational appears when there are no other messages.
Differences Using the Async Terminal: The menu
structure for the Status branch changes slightly from the
front panel to allow you to display health and status
information from one screen. To do this, 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.

Operation
Registers shown on the front panel LCD are listed in
Performance Report
Table 3-11. 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.
Network performance is continuously monitored and
maintained in internal memory registers when the network
interface is configured for ESF operation. The DSU/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).
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 3-35.
These registers are accumulators or status registers that
collect performance data for the previous 24-hour period.

Operation
Deactivating the Alarm Relay
Starting Front Panel
Emulation
The front panel emulation function enables you to
display the front panel of a specified near-end or far-end
316x DSU/CSU on a PC. If the DSU/CSU selected is not
locally attached to the PC, you must first dial to the
remote DSU/CSU before starting front panel emulation.
The Alarm Cut-off command forces a deactivation of
the alarm relay on the 3000 Series Carrier during an alarm
condition. Since this function only affects the 3000 Series
Carrier, it is only available for Model 3161 DSU/CSUs.
The alarm relay function must first be enabled by the
Alarm Relay configuration option (see Appendix C,
Configuration Options).
To start front panel emulation,
To deactivate the alarm relay,

Using the Async Terminal
Feature
You can use an async terminal to manage the
3160/3164 DSU/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.
4. Enter the Com Port and Speed from the
drop-down selection list boxes.
The Com Port field should contain the actual
communications port name as recorded in the
Windows information file (INI).
The Speed field should contain one of the
following communications speeds: 1200, 2400,
4800, 9600, 14400, or 19200 and should match the
DSU/CSU COM port configuration.
Setting Interface Options
5. Choose either a Local (for near-end DSU/CSU) or
Remote (for far-end DSU/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 3-13 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 DSU/CSU in the Phone Number field,
then click on the Dial button.
7. The front panel of the selected 316x DSU/CSU
appears on the PC.

After the async terminal configuration options are set,
the changes must be saved and made active. Depending on
your preference, changes are saved to the Customer (Cust)
Configuration option set which, in turn, must be written to
the active Configuration option set to take affect. Or, they
are saved directly to the Active Configuration Option set.
Refer to the Configuration Option Areas section earlier in
this chapter for information on saving changes to the
Configuration option sets.
Enter Password: _________
Initiating an Async Terminal Session
Once the async terminal is connected and the
configuration option changes are active, modem port users
must dial-in through a modem connection to initiate a
session using the async terminal. COM port connections
automatically display the first level menu provided a
password is not required.
Figure 3-42. Password Access Screen
Async Terminal Menus and Screens
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.
Panel, Modem, or COM Port.
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 3160/3164
DSU/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 terminal
interface also supports the same context sensitivity as the
front panel.
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 DSU/CSU’s top-level
menu is displayed.
By convention throughout this manual, examples of
screens that access the data ports are always shown as
they appear with the 4-port 3164 DSU/CSU. Menus for
the 2-port DSU/CSU only display the information for
Port 1 and Port 2.
•
If the password is invalid, an invalid password
message displays and the Password Access Screen
redisplays and waits for password entry
.
The top line of every screen always displays the menu
path for the function (or configuration option) being
displayed. The second line shows the customer
identification (CID) number and the DSU/CSU’s model
number. The remaining screen area is used for menu or
option-specific information.
Figure 3-42 shows an example of the Password Access
screen.
There are three screen types: menu selection, edit and
display screens. Menu screens list selections available
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.
Appendix A provides a complete Front Panel Menu
tree which illustrates a menu structure similar to that
supported by the async terminal interface. Refer to this
appendix for assistance when navigating through the
menu system.
All functions operate the same throughout the async
terminal interface whenever they appear at the bottom of
the screen. These functions include the following:
Alarm conditions are indicated on the upper right
corner of the menu screen under the header LED Status.
For example, if an alarm is reported on the DTE interface,
DTE appears under LED Status in inverse video.
Likewise, Test appears if a test is running on a device.
NET appears to report alarms on network. Chan appears
if any of the data ports are configured to generate All
Ones (refer to the All Ones configuration option in the
Port Configuration Options section of Appendix C).
When these indicators appear, they reflect the current
status upon entering into the menu system or whenever
you return to the main menu.

Overview
Troubleshooting
The ACCULINK 316x DSU/CSU can detect and
report faults, perform diagnostic tests, and download
software. These features ensure that your DSU/CSU is
giving you optimum performance in your network.
The DSU/CSU offers a number of front panel alarms to
alert you to possible problems. Once problems are
detected, you can use the troubleshooting table
(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 available.

Alarms
The 316x DSU/CSU monitors alarm conditions
occurring on either the network interface or the DSX-1
Drop/Insert port (DTE). For Model 3160/3164
DSU/CSUs, you can route these alarms to the MODEM
port, the COM port, or both. Each alarm is preceded by
the customer identification so you know which DSU/CSU
is having the problem. Possible alarm messages are as
follows, where x is the DTE or Network interface where
the condition exists.
•
•
Yellow alarm signal received at the x Interface.
Alarm Cleared. Yellow alarm signal at the x
Interface.
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.
For Model 3161 DSU/CSUs, these alarms activate the
alarm relay, if so configured.
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.

is generated when an interface transitions from an up state
to a down state. A link-up is generated when an interface
transitions from a down state to an up state. Table 4-1
defines traps for each interface.

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 and tests run
on ports, as shown in Figure 4-2.
Test Commands
The test commands enable you to run loopbacks and
test patterns on the DSU/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 316x DSU/CSU.
Access all Test commands from the Test branch of the
front panel menu tree (see Figure 4-1).

the receipt of a DCLB-actuate sequence or DCLB-release sequence (either V.54 or FT1 (ANSI) compliant sequences)
from the network or far-end DSU/CSU.
NOTE: When this configuration option is enabled (for V.54, FT1, or both), receiving a DCLB-actuate sequence on a
particular port causes the DSU/CSU to initiate a DCLB on that port, provided that a DCLB can be performed
based on the current state of the port and DSU/CSU. Receiving the DCLB release sequence terminates the
DCLB.
Disab – Ignores the DCLB-actuate and DCLB-release sequences for this port.
V.54 – Enables DCLB-actuate and DCLB-release sequences that comply with the V.54 standard for ‘‘Inter-DCE signaling
for point to point circuits.”

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.
NOTE: This configuration option is not displayed on Model 3161 DSU/CSUs.
Call Retry: Disab
Next Enab Disab Prev
Call Retry on Alarm. Determines whether an uncompleted call is retried. Calls initiated while attempting to send an alarm
or trap message to the MODEM port are retried after a five-minute delay if this configuration option is enabled.
Enab – Retries calls up to five times with a five-minute delay between each. If an alternate dial-out directory is specified,
both the alarm directory and the alternate directory are retried up to five times.
Disab – Prevents calls from being retried if they cannot be completed.

Alternate Dial Out Directory for Alarm or Trap. Specifies whether a call that cannot be completed is retried using an
alternate phone number. The alternate telephone number resides in one of the five call directories. If call retry is enabled,
the initial call is retried at the original number five times before a call attempt to the alternate number is tried. If the call is
not completed at the alternate number, it is retried up to the five retry maximum. The alternate dial-out option applies to
each alarm or trap event.
None – Specifies that alternate alarm dial-out is not performed when a call cannot be completed to the telephone number
contained in the alarm directory.
1–5 – Specifies the call directory that contains the phone number to call when a call cannot be completed to the
telephone number contained in the alarm directory.

Power Cable
Power Input Connector
The power cable is a 14.5-foot, 18 AWG stranded
cable. The connector is terminated at one end with a
6-position Molex 39-01-2060 connector. The other end of
the cable is terminated with a bare wire that should be
connected to a DC power source. Figure D-9 shows the
wire colors. The power source can be either a single
source of +24 Vdc or up to two sources of –48 Vdc
(A and B). You cannot connect +24 Vdc and –48 Vdc to
the same unit. See the installation instructions in
Chapter 2, Installation.
The required input power connector leads are shown in
Table D-10.

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 DSU/CSU provides an entry in the interface table for
the Network T1 interface, the DTE Drop/Insert T1
interface, each of the synchronous DCE data ports (1, 2,
or 4 depending on the model), the COM port, and the
MODEM port. The following sections provide
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 DSU/CSU:

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.

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.

Glossary
AIS
Alarm Indication Signal. A signal transmitted instead of the normal signal to
continue transmission continuity and to indicate to the receiving terminal that a
transmission fault exists at either the transmitting terminal or upstream of the
transmitting signal. Sometimes referred to as Blue Alarm.
AMI
Alternate Mark Inversion. A line encoding technique and a bipolar return-to-zero
signal.
Async Terminal
This feature allows a DSU/CSU to be controlled from an asynchronous (async)
terminal. When this feature is enabled, the async terminal menus and displays
emulate the DCP without being limited to the 2-line LCD display.
Auxiliary Backplane
An 8-slot backplane that fits over one half of the open section of the 3000 Series
Carrier. This is a passive assembly that provides interconnect capability between
3151 CSUs and 3161 DSU/CSUs and provides all interface connectors.
AWG
BES
American Wire Gauge.
Bursty Error Seconds. A second in which more than one, but less than 320 CRC6
error events, have occurred.
BPV
Bipolar Violation. A modified bipolar signaling method in which a control code is
inserted into the original data format.
B8ZS
CRC
CSU
Bipolar with 8 Zero Substitution.
Cyclic Redundancy Check. A method of error detection.
Channel Service Unit. Protects the T1 line from damage and regenerates the
T1 signal.
DCE
DSU
Data Communications Equipment.
Data Service Unit. Data communications equipment which transmits digital data
over a private line. Also used for limited distance communications over the PSTN
when a high-speed modem is not needed.
DS0
Digital Signal level 0. A signal of worldwide standard speed for PCM digital voice
channels running at 64 kbps.
DS1
Digital Signal level 1. A signal of 1.544 Mbps in North America.
DSX-1
Digital Signal Cross Connect level 1. An interconnection point for terminals,
multiplexers and transmission facilities.
DTE
DTMF
D4
Data Terminal Equipment.
Dual Tone Multifrequency. The basis of operation for a pushbutton telephone.
The transmission standard that specifies 12 frames as a superframe that is used for
frame synchronization and to locate signaling bits.

Errored second. A second with one or more ESF error events (one or more CRC6
error events or OOFs).
ESD
ESF
Electrostatic discharge.
Extended Superframe. The T1 transmission standard that specifies 24 frames as an
extended superframe to be used for frame synchronization and to locate signaling
bits.
FCC
FDL
Federal Communications Commission.
Facility Data Link. The selected bits in the ESF format that are used for control,
monitoring and testing.
LBO
Line Build-out. The amount of attenuation of the transmitted signal that is used to
compensate for the length of wire between the transmitter and the receiver.
LCD
LED
LOF
Liquid Crystal Display.
Light-Emitting Diode.
Loss of Frame. Occurs when a DS1 terminal is unable to synchronize on the DS1
signal for some interval (nominally 2 1/2 seconds).
LOFC
LOS
Loss of Frame Count. A count of the number of LOFs declared.
Loss of Signal. The T1 line condition where there are no pulses.
MIB
Management Information Base. Database of managed objects used by SNMP to
provide network management information.
MUX
OOF
PDV
Multiplexer.
An error condition in which two out of four synchronization bits are in error.
Pulse Density Violation.
PPP
Point-to-Point Protocol. A link layer protocol used by SNMP.
Public Switched Telephone Network.
PSTN
QRSS
Quasi-Random Signal. A test pattern simulating a random pattern of digital ones
and zeros used to simulate normal transmission.
SDCP
SES
Shared Diagnostic Control Panel.
Severely Errored Seconds. A second with 320 or more CRC6 error events or one or
more OOFs occurring.
SLIP
Serial Line Internet Protocol. A link layer protocol used by SNMP.
SNMP
Simple Network Management Protocol. A generic network management system that
allows the device to be managed by any industry-standard SNMP manager
.
UAS
Unavailable Seconds. A count of 1-second intervals when service is unavailable.
Vac
Volts alternating current.
Volts direct current.
