3160/3164 DSU/CSU.
• Async terminal interface support.
• DSX-1 Drop/Insert port.
• Front Panel Access Control feature.
• SNMP Management Support.
User Interface
There
are three ways of accessing the user interface:
• Front panel
which enable you to display information about and
interact with the DSU/CSU. A menu tree is
available which enables control of the DSU/CSU in
the network (see Appendix A, Front Panel Menu).
• COM Port – used for 3100 Series Front Panel
Emulation software which displays the DSU/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 (3160/3164 only).
For Model 3161 DSU/CSUs, only one slot in the
carrier can be configured as the COM port; all slots
share the PC.
• MODEM Port – provides 3160/3164 DSU/CSU
functionality from a PC attached either remotely or
by using pass-through via another DSU/CSU
(3160/3164 only). It is also used for the async
terminal connection. This port is located only on
3160/3164 DSU/CSUs.
– provides an LCD and a keypad
Alarm Interface
The 3160/3164 DSU/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 DSU/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.
Integral Modem
The 3160/3164 DSU/CSUs contain an integral modem
that enables communication with remote devices such as
another 316x DSU/CSU, or an ASCII terminal or printer.
This is a low-speed (2400 bps), V.22bis 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 316x
DSU/CSU.
1-2December 19963160-A2-GB22-10
Alarms can also be displayed on a PC that is using a
terminal emulation package.
Model 3160/3164 DSU/CSUs can be configured to
generate traps on alarms which can be sent to an SNMP
manager via either the MODEM or COM port.
Page 17
Introduction
Front Panel Emulation
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.
For 3161 DSU/CSUs, a single PC is used to access all
of the slots in the carrier
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 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.

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 3160/3164 DSU/CSU supports the Simple
Network Management Protocol (SNMP), V
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
Open Management Application for HP OpenV

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.
The 3160/3164 DSU/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
DSU/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 synchronous data ports and
management communication ports on the
DSU/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 DSU/CSU’
data interfaces that are not supported by other
MIBs.

• One 2-line, 16-alphanumeric character per line
liquid crystal display (LCD)
• 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.
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, ConfigurationOptions).
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
SNMP manager under various alarm conditions.

ACCULINK 316x DSU/CSU
Carrier-Mounted Model 3161 DSU/CSU
The
3161 DSU/CSU is a circuit card that is installed
into the 3000 Series Carrier. A single carrier can house up
to 16 DSU/CSUs; the DSU/CSUs are controlled by the
carrier’s Shared Diagnostic Control Panel (SDCP), which
can control up to eight carriers. Rear panel connections
are provided by the Auxiliary Backplane, which is
installed on the rear of the carrier.
Model 3161 Front Panel Functions
The
twelve LEDs and six test jacks provided on the
faceplate of the Model 3161 DSU/CSU are the same in
function as those provided on the front panel of the
3160/3164 DSU/CSU (see Figure 1-5). Other front panel
functions, including a keypad and LCD, are provided by
the SDCP of the 3000 Series Carrier
. These SDCP
functions are described in the COMSPHERE 3000 Series

Planning
The ACCULINK 316x DSU/CSU is designed to
provide an interface between the T1 digital network and
the Customer Premise Equipment (CPE). The DSU/CSU
must be connected to the CPE through its DSX-1 (DTE)
Drop/Insert port or one of the data ports, and then to the
network through the DSU/CSU Network Interface (NET)
port. The most common configurations for the 316x
DSU/CSU are:
• Point-to-point LAN interconnection (Figure 2-1).
Shared access to network-based services
•
(Figure 2-2 ).
• Multiport T1 DSU/CSU in a fractional
T1 network (Figure 2-3).
• Central-site T1 termination for Model 3161
DSU/CSUs (Figure 2-4).
Both voice and data applications are supported.

agent, can be connected to and managed from an SNMP
management system in one of two 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) (Figure 2-5).

Power-Up Self-Test
After you connect the 3160/3164 DSU/CSU to a power
outlet, the power-up self-test is performed to ensure that
the unit is in good working order. The DSU/CSU
performs this test on itself upon power-up or after a device
reset unless it has been disabled by the Self-T
configuration option (see Appendix C,
Options).
The 3161 DSU/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-T
command to display the status of the test (see

functions available through the menu tree. This is the
default setting.
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,
Y
ou can only reach the screen that controls security
access using the front panel; you cannot access this option
using front panel emulation, async terminal, or the modem
interface.

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.
Keypad
The 7-button keypad enables you to navigate through
the menu tree and select choices presented on the second
line of the LCD (Figure 3-5).
LCD
Device Health and Status Messages
The
316x DSU/CSU features status messages that
appear on the front panel LCD. Y
ou 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.
Other Displays
The
LCD also lists commands, configuration options,
and test results. In most cases, the top line shows the
command or option name and default value, while the
second line displays options and responses. When a
response is required, select from the options displayed
directly above the Function keys (F1, F2, F3); make your
choice by pressing the corresponding Function key.

Front Panel Emulation on a PC
The 316x DSU/CSU front panel can be mimicked on
an attached PC. This front panel emulation capability
allows you to access the 3160/3164 DSU/CSU (local or
remote) through a PC connected to the COM or MODEM
port. For 3161 DSU/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 3-9) to control the
DSU/CSU from a PC just as though you are operating
from the DSU/CSU’s own front panel. The PC window is
updated every five seconds to show the current state of the
DSU/CSU.

Configuring the DSU/CSU
You have the option of customizing your 316x
DSU/CSU for optimum performance in your network. To
do so, use the DSU/CSU configuration options.
Appendix G contains a set of blank worksheets to use
when configuring your 316x DSU/CSU in the network.
Configuration Option Areas
The 316x DSU/CSU offers four sets of configuration
options located in the following areas:
• Active (Activ). The configuration option set active
for the DSU/CSU is stored here. Before a set of
configuration options become active for the
DSU/CSU, you must save the set to the Active area.
When the DSU/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)
customer-defined configuration options. Customer
set is identical to the Factory 1 set when the

market. Factory 2 options are read-only.
Configuration Options
The configuration options are divided into seven
functional groups. Appendix C contains a list of the
configuration options and defaults. These groups are:
• DTE (DSX-1) Interface (see Table C-1)
• Port (see Table C-2)
• Network Interface (see Table C-3)
Channel (see T
•
• General (see Table C-6)
• User Interface (see Table C-7)

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

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,
Options
for more information about how to set these traps.
Trap types consist of the following:
• 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 3-7 for enterprise-specific traps. These traps
are set by the Entp Trap configuration option.
Link T
raps
•
– 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.

Configuring DS0 Channels
The 316x DSU/CSU provides channel configuration
options that allow you to do the following:
Display the DS0 assignments for the Network and
•
DSX-1 Drop/Insert T1 interfaces.
• Allocate DS0 channels on the DSX-1 Drop/Insert
T1 interface to the Network interface.
• Allocate DS0 channels on the Network or DSX-1
Drop/Insert T1 interfaces to particular data ports.
• Clear (deallocate) all DS0 channels from the
Network or DSX-1 Drop/Insert T1 interfaces.
To allocate DS0 channels, begin by defining logical
channel configuration for Network interface, and then the
DTE Drop/Insert interface, and then any ports, if desired.
See Figure 3-24 for an example of a conceptual diagram
of channel configuration.
To complete the configuration worksheets for DS0
channel allocation:
1. Complete the Network T1 Interface and the
DSX-1 Drop/Insert Interface tables (unless the
DSX-1 Drop/Insert interface is disabled) as shown
in Figure 3-25. Figure 3-26 contains a worksheet
for specifying which DS0 channels carry Robbed
Bit Signaling (RBS) information for voice
channels. Figures 3-27 and 3-28 contain a
worksheet for allocating data ports.
Using the worksheets provided in Appendix G,

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.
3160/3164
NOTE
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.

Selecting the Shared
Communication Port
Communication
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
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.
If a Model 3161 DSU/CSU is
configured as the Master
Communication Unit, Port 2
