Government Requirements 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 standalone 3160, 3164, or 3165 DSU/CSU, and on the 3161 DSU/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 DSU/CSU can be configured to support any of the
following framing format and line signaling techniques. The DSU/CSU’s configuration must correspond to the T1
line’s parameters. The standalone 3160, 3164, or 3165 DSU/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 3161
DSU/CSU connects to the T1 network using the multi-line USOC-type RJ48H jack and does not have a PSTN
interface.
316x DSU/CSU Facility Interface Codes
Code Description
04DU9-BN 1.544 Mbps superframe format (SF) without line power
04DU9-DN 1.544 Mbps SF and B8ZS without line power
04DU9-1KN 1.544 Mbps ANSI ESF without line power
04DU-1SN 1.544 Mbps ANSI ESF and B8ZS without line power
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.
5. The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect
the operation of the equipment. If this happens, the telephone company will provide advance notice in order for
you to make the necessary modifications in order to maintain uninterrupted service.

Introduction

Overview
The ACCULINKR 316x DSU/CSU acts as an interface between the T1 digital
network and the customer premises equipment, converting signals received from
the DTE (Data Terminal Equipment) to bipolar signals that can be transmitted
over T1 lines. Typical applications include shared access to network-based
services, Local Area Network (LAN)/Wide Area Network (WAN) interconnection,
and fractional T1 network applications.
In addition to the T1 network interface and the DTE Drop/Insert (DSX-1)
interface, the Model 3160 provides two synchronous data ports while the Model
3164 provides four synchronous data ports. The Model 3165 provides one
synchronous data port, but does not provide the DTE Drop/Insert (DSX-1)
interface.
The Model 3161 (carrier-mounted DSU/CSU) provides two ports in addition to the
DTE Drop/Insert (DSX-1) interface and is designed to fit into the COMSPHERE
3000 Series Carrier.
For more information about the carrier-mounted DSU/CSU, refer to the
ACCULINK 3151 CSU and 3161 DSU/CSU General Information Guide
and the
COMSPHERE 3000 Series Carrier Installation Manual
.
Features
The DSU/CSU optimizes network performance with a wide range of features such
as the following:
H Software configuration menu displayed via a liquid crystal display (LCD) to
permit quick and easy operation, and elimination of complicated hardware
strapping.
H Local or remote configuration and operation flexibility.
H Several loopback capabilities and test pattern generators.
H DTE Drop/Insert (DSX-1) capability.
H Alarm message display/print capability.
H Front panel emulation via Windows-based Front Panel Emulation software.
Introduction
1-2
3160-A2-GB21-80
March 1999
Integral modem for standalone DSU/CSUs.
Asynchronous (async) terminal interface support.
Telnet access for remote async terminal operations.
Network management provided through industry-standard Simple Network
Management Protocol (SNMP).
DTE Drop/Insert (DSX-1) Interface
The DTE Drop/Insert interface allows DTEs/PBXs that support the DS1 signal
format to share the T1 network with other high-speed equipment. This is available
on 2-port and 4-port DSU/CSUs.
Alarm Message Capability
The DSU/CSU can be attached, either locally or remotely, to an ASCII terminal or
printer to display or print alarm messages. Alarms can also be displayed on a PC
that is using a terminal emulation package.
Front Panel Emulation
The DSU/CSU offers functionality through Front Panel Emulation software that is
similar to that provided by the DSU/CSU front panel. The 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.
Integral Modem
The standalone DSU/CSUs contain an integral low-speed (2400 bps), V.22bis
dial modem that enables communication with remote devices such as another
316x DSU/CSU, an ASCII terminal or printer, or a PC running the 3100 Series
Front Panel Emulation software.
Async Terminal Interface Support
The DSU/CSU can be configured and managed from an asynchronous (async)
terminal. The async terminal’s full screen display uses a menu hierarchy similar
to the DSU/CSU’s front panel. You can perform device management and
configuration operations as if you are using the DSU/CSU’s front panel, but you
do not have the limitation of the 2-line, 16-character LCD.
Telnet Access
Remote async terminal operations can be performed using Telnet access. Telnet
is a Transmission Control Protocol/Internet Protocol (TCP/IP) service that
supports a virtual terminal interface.

3160-A2-GB21-80

SNMP Management Support
SNMP is a network management protocol 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
or PC; an agent consisting of a software program housed within a device (e.g.,
the DSU/CSU); and a Management Information Base (MIB) consisting of a
database of managed objects. The DSU/CSU can be managed by any
industry-standard SNMP manager.
Two link layer protocols, Point-to-Point Protocol (PPP) and Serial Line Internet
Protocol (SLIP), are supported for connection to an external SNMP manager or
network device (e.g., a router).
The SNMP manager or network device can be directly connected to the
communications (COM) port. An external LAN Adapter can be connected to
either the COM port or the auxiliary (AUX) port to provide Ethernet connectivity.
Also, the DSU/CSU can be daisy chained together by connecting the COM port of
one device to the AUX port of the other, providing SNMP connectivity.
The SNMP management system can communicate to the DSU/CSU remotely
through the Facility Data Link (FDL) or (for 2-port and 4-port DSU/CSUs) the
synchronous data port’s Embedded Data Link (EDL).
Physical Description
The 316x Series consists of a Model 3160 DSU/CSU (2-port), a Model 3164
DSU/DSU (4-port), a Model 3165 DSU/CSU (1-port), and a Model 3161
(carrier-mounted) DSU/CSU.
For more information about the carrier-mounted DSU/CSU, refer to the
ACCULINK 3151 CSU and 3161 DSU/CSU General Information Guide
and the
COMSPHERE 3000 Series Carrier Installation Manual
.
Standalone DSU/CSU Front Panel
The standalone 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)

Overview
This chapter contains information for installing your standalone DSU/CSU. It
includes application examples, cabling, and power-up information.
NOTE:
Installation instructions for the carrier-mounted DSU/CSU are located in the
ACCULINK 3151 CSU and 3161 DSU/CSU General Information Guide
and
the
COMSPHERE 3000 Series Carrier Installation Manual
.
Application Examples
The DSU/CSU acts as an interface between the T1 digital network and the
customer’s equipment.
The DSU/CSU is connected to the customer’s equipment through one of the
synchronous data ports (PORTs 1–4) or the DTE Drop/Insert (DSX-1) interface. It
is connected to the T1 digital network through the network interface.
NOTE:
The DTE Drop/Insert (DSX-1) interface is only available on 2-port and 4-port
DSU/CSUs.
Some common applications for the DSU/CSU are:
Point-to-Point LAN interconnection (Figure 2-1).
Shared access to network-based services (Figure 2-2).
Fractional T1 network applications (Figure 2-3).

SNMP or Telnet Connection Examples
The DSU/CSU can be connected to an SNMP or Telnet system in a number of
ways. Some examples include:
Directly connecting the COM port to the SNMP or Telnet device (Figure 2-4).
Connecting the COM port to a network device (e.g., a router) (Figure 2-5).
Connecting the COM port or the AUX port to an external LAN Adapter for
Ethernet connectivity (Figure 2-6).
Daisy chaining the COM port of one device to the AUX port of the other
(Figure 2-7).
Remotely accessing the DSU/CSU through the Facility Data Link (FDL) or the
synchronous data port’s Embedded Data Link (EDL) (Figure 2-8).
NOTE:
EDL is only available on 2-port and 4-port DSU/CSUs.
