NOTICE TO USERS OF THE UNITED STA
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 T
elephone Company
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 T
Facility Interface Code 02LS2 along with the RJ1
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

Overview
The ACCULINKr 316x Series ESF T1 Data Service
Unit (DSU)/Channel Service Unit (CSU) acts as an
interface between the T1 digital network and the
Customer Premise Equipment (CPE), converting signals
received from the DTE (Data Terminal Equipment) to
bipolar signals that can be transmitted over T1 and
Fractional T1 lines. Typical applications include Local
Area Network (LAN)/Wide Area Network (WAN)
interconnection, channel extension, and video
teleconferencing.
In addition to the T1 Drop/Insert port, the ACCULINK
Model 3160 provides two DTE ports while the
ACCULINK Model 3164 provides four DTE ports.
The ACCULINK Model 3161 provides two ports in
addition to the T1 Drop/Insert port and is designed to fit
into the COMSPHEREr 3000 Series Carrier.

with a wide range of benefits such as the following:
• Software configuration menu displayed via an LCD
to permit quick and easy operation and elimination
of complicated hardware strapping.
• Flash memory software download capability to
ensure investment protection.
• Trouble-free installation facilitated by two factory
installed settings which anticipate the most
common applications: either D4 or ESF framing
standards, and B8ZS or AMI line coding standards.
• Security features to ensure network integrity.
• Network management for 3160/3164 DSU/CSUs
provided through industry-standard SNMP.
Multipower source acceptance.
•
• Local or remote configuration and operation
flexibility.
Several loopback capabilities, test pattern
•
generators and external contact closure for DTE

ACCULINK 316x DSU/CSU
• Independently selectable DTE interfaces (V.35,
EIA-530A, V.11, and/or RS449/422).
• Flexible timing source, available from the
T1 network interface, the DSX-1 T1 interface, at
least one of the synchronous DCE data ports, an
internal clock, or an external clock.
• Flexible, user-friendly channel allocation.
The 3160/3164 DSU/CSUs are available in a compact
standalone case (Figure 1-1) that can be mounted on a
desktop, shelf, or wall. The 3161 DSU/CSU is available
as a circuit card that is installed into a COMSPHERE
3000 Series Carrier.
Features
The 316x DSU/CSU offers a wide variety of features:
• Integral modem for 3160/3164 DSU/CSUs only
which enables remote operation to enhance
serviceability and increases uptime.
• User interfaces for access to configuration and
alarm information.
• Front Panel Emulation via Windowst-based front
panel emulation software.
Front panel pass-through to access a remote
•
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.
1-2 December 1996 3160-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.
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.
. The PC is connected locally to a
Front Panel Pass-Through
Pass-through (passthrough
the local DSU/CSU to access the front panel of a remote
316x DSU/CSU using the integral modem. In addition,

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
Guide.

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.

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/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.
3160/3164 DSU/CSU Front Panel
The 3160/3164 DSU/CSU front panel contains,
• 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, Configuration
Options).
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.

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.
