Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or included in the manual.
2. This product is intended to be used with a 3-wire grounding type plug – a plug which has a grounding pin. This is
a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the
grounding type plug by modifying the plug or using an adapter.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for the presence of earth
ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician
has corrected the problem.
If a 3-wire grounding type power source is not available, consult a qualified electrician to determine another
method of grounding the equipment.
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to
protect it from overheating, these slots and openings must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the
power cord.
5. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous
high voltage points or other risks. Refer all servicing to qualified service personnel.
6. General purpose cables are provided with this product. Special cables, which may be required by the regulatory
inspection authority for the installation site, are the responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable Safety Standards and
regulatory requirements of the country in which it is installed. If necessary , consult with the appropriate regulatory
agencies and inspection authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If
products installed in separate buildings are interconnected, the voltage potential may cause a hazardous
condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if
necessary, implement corrective action prior to interconnecting the products.
9. Input power to the ac voltage configuration of this product must be provided by a UL-listed or CSA-certified power
source with a Class 2 or Limited Power Source (LPS) output.
10. This product contains a coin cell lithium battery that is only to be replaced at the factory . Caution: There is a
danger of explosion if the battery is incorrectly replaced. Replace only with the same type. Dispose of used
batteries according to the battery manufacturer’s instructions. Attention: Il y a danger d’explosion s’il y a
remplacement incorrect de la batterie. Remplacer uniquement avec une batterie du même type. Mettre au rebut
les batteries usagées conformément aux instructions du fabricant.
1 1.In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:
— Never install telephone wiring during a lightning storm.
— Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
— Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
— Use caution when installing or modifying telephone lines.
— Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of
electric shock from lightning.
— Do not use the telephone to report a gas leak in the vicinity of the leak.

Introduction
Overview
1
The ACCULINKr 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 3162 provides two synchronous data ports.
Features
The DSU/CSU optimizes network performance with a wide range of features such
as the following:
HLocal or remote configuration and operation flexibility.
HSeveral loopback capabilities and test pattern generators.
HDTE Drop/Insert (DSX-1) capability.
HAsynchronous terminal interface support.
HAlarm message display/print capability.
HTelnet access for remote asynchronous terminal operations.
HNetwork management provided through industry-standard Simple Network
Management Protocol (SNMP).
3162-A2-GB20-40
August 2000
1-1
Introduction
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.
Asynchronous Terminal Interface Support
The DSU/CSU can be configured and managed from an asynchronous (async)
terminal. The asynchronous terminal’s full screen display uses a menu hierarchy
to perform device-control operations.
Chapter 3, Operation, provides operational examples to help you become familiar
with the use of the asynchronous terminal for DSU/CSU control.
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.
Chapter 5, Monitoring and Testing, provides a list of alarm messages.
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.
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.
1-2
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).

Power-On Self-Test
After you connect the DSU/CSU to a power source, the unit performs the
power-on self-test to ensure that it is in good working order. The DSU/CSU
performs this test on itself upon power-on or after a device reset, unless it has
been disabled by the Self-Test 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.
" Procedure
The power-on self-test consists of the following steps:
1. Once the DSU/CSU is plugged in, the Fail LED blinks ON and Off
continuously.
2. All the LEDs then start to flash simultaneously in the pattern twice ON, then
Off.
3. If the self-test is successful, the Fail LED turns Off and the OK LED lights.
If the self-test fails, the Fail LED lights. The DSU/CSU continues to try to
operate. If you are in doubt about the results of the self-test, use the System
and Test Status screen to display the results of this test (see Self-Test
Results in Chapter 5, Monitoring and Testing).

Operation
Overview
This chapter contains information for operating your DSU/CSU. It includes a
description of the front panel LEDs and sample procedures to help you become
familiar with the use of the asynchronous terminal for DSU/CSU control.
Front Panel LEDs
There are twelve LEDs on the DSU/CSU front panel. The five LEDs on the right
(Figure 3-1) are shared between the DTE Drop/Insert (DSX-1) interface and the
data ports. Use the Control branch of the asynchronous terminal menu tree to
choose which port’s status the LEDs display (see Menu Organization on
page 3-7).

3162-A2-GB20-40
Figure 3-1. DSU/CSU LEDs
A green LED indicates normal operation. A yellow LED indicates a warning (for
the DTE Drop/Insert interface) or activity (for the data ports). Conditions are
sampled every tenth of a second.
The twelve front panel LEDs are grouped into four sections to indicate the status
