Overview

The 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,
the Model 3163 provides one synchronous data port.

Features

The Model 3163 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.

• Alarm message display/print capability.

• Front panel emulation via Windows-based Front

Panel Emulation software.

• Integral modem for standalone DSU/CSUs.

• Asynchronous (async) terminal interface support.

• T elnet access for remote async terminal operations.

1-13163-A2-GB20-10 March 1999

ACCULINK 3163 DSU/CSU

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 3163 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 3163 DSU/CSU 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.

Asynchronous Terminal Interface Support

The 3163 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. Telnet is a Transmission Control
Protocol/Internet Protocol (TCP/IP) service that supports
a virtual terminal interface.

Installation

Power-Up Self-Test

After you connect the DSU/CSU to a power source, the
unit performs the power-up self-test to ensure that it 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 est configuration option (see
Appendix C, Configuration Options).

The self-test includes a basic processor test, a limited
memory test, a code checksum test, and basic verification
tests of the internal components. The front panel LCD
displays the progress and pass/fail status of these
power-up tests.

" Procedure

The power-up self-test consists of the following steps:

1. Once the DSU/CSU is plugged in, the In Progress
screen appears and the Fail LED blinks ON and
Off continuously.

Self-Test:
In Progress

If the self-test fails, the Failed screen appears for
five seconds. The Fail LED lights, and an
eight-digit failure code (xxxxxxxx) is displayed for
use by service personnel to determine the cause of
the self-test failure. The DSU/CSU continues to
try to operate. If you are in doubt about the results
of the self-test, use the Self-T est Health command
to display the status of this test (see the Self-Test

Health section in Chapter 4, Maintenance).

the pattern twice ON, then Off. Then, the LCD
begins to flash characters and numbers in the same
pattern, alternating with the flashing LEDs.

appears for one second, the Fail LED turns Off
and the OK LED lights.
