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 stan dal on e 316 0, 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

Introduction
Overview
1
The ACCULINK® 316x DSU/CSU acts as an interface between the T1 digital
network and the customer premises equipment, converting signals received from
the DTE (Data T erminal 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 and the Model 3164
provides four synchronous data ports. The Model 3165 provides one synchronous
data port, but no DTE Drop/Insert interface.
Features
The Model 3161 (carrier-mounted DSU/CSU) provides two ports in addition to the
DTE Drop/Insert (DSX-1) interface and is designed to be installed in the
COMSPHERE 3000 Series Carrier.
For more information about the carrier-mounted DSU/CSU, refer to the
3151 CSU and 3161 DSU/CSU General Information Guide
3000 Series Carrier Installation Manual
The DSU/CSU optimizes network performance with a wide range of features such
as the following:
Software configuration menu displayed via a liquid crystal display (LCD) to
permit quick and easy operation, and elimination of complicated hardware
strapping.
Local or remote configuration and operation flexibility.
Several loopback capabilities and test pattern generators.
DTE Drop/Insert (DSX-1) capability.
Alarm message disp lay/pr in t capab il ity.
Front panel emulation via Windows-based Front Panel Emulation software.

1. Introduction
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 T elnet access. T elnet is
a Transmission Control Protocol/Internet Protocol (TCP/IP) service that supports a
virtual terminal interface.
March 2001 3160-A2-GB24-10

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 or can be accessed via Ethernet using the 10BaseT
port.
On the Model 3164, 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
Model 3164 to the AUX port of another, providing SNMP connectivity.
1. Introduction
The SNMP management system can communicate to the DSU/CSU remotely
through the Facility Data Link (FDL) or 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
3151 CSU and 3161 DSU/CSU General Information Guide

and
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-P oint LAN interconnection (Figure 2-1, Point-to-Point Application
Example).
Shared access to network-based services (Figure 2-2, Shared Access
Application Example).
Fractional T1 network applications (Figure 2-3, Fractional T1 Application
Example).

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,
Direct Connection).
Connecting the COM port to a network device (e.g., a router) (Figure 2-5,
Connection through a Router).
Connecting to an Ethernet LAN through the 10BaseT port (Figure 2-6,
Connection through the 10BaseT Port).
Remotely accessing the DSU/CSU through the Facility Data Link (FDL) or the
synchronous data port’s Embedded Data Link (EDL) (Figure 2-7, Remote
Access through FDL/EDL).
On the Model 3164, connecting the COM port or the AUX port to an external
LAN Adapter, or daisy chaining the COM port of one Model 3164 to the AUX
port of another for Ethernet connectivity.
