NOTICE TO USERS OF THE CANADIAN TELEPHONE NETWORK
The Industry Canada label identifies certified equipment. This certification means that the equipment meets
telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal
Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to
the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connection. The
customer should be aware that compliance with the above conditions may not prevent degradation of service in some
situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines
and internal metallic water pipe system, if present, are connected together. This precaution may be particularly
important in rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but should contact the appropriate
electric inspection authority, or electrician, as appropriate.
The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum
number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of
any combination of devices subject only to the requirement that the sum of the Ringer Equivalence Numbers of all the
devices does not exceed 5.

Introduction 1
Overview
The ACCULINKR3166 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.
The Model 3166 is designed to fit into the COMSPHERE 3000 Series Carrier. For
more information about the carrier, refer to the
COMSPHERE 3000 Series Carrier
Installation Manual .
Features
The DSU/CSU optimizes network performance with a wide range of features such
as the following:
HSoftware configuration menu displayed via an optional liquid crystal display
(LCD) to permit quick and easy operation, and elimination of complicated
hardware strapping.
HLocal or remote configuration and operation flexibility.
HSeveral loopback capabilities and test pattern generators.
HAlarm message display/print capability.
HFront panel emulation via Windows-based Front Panel Emulation software.
HAsynchronous (async) terminal interface support.
HTelnet access for remote async terminal operations.
HNetwork management provided through industry-standard Simple Network
Management Protocol (SNMP).

Introduction
1-2 3166-A2-GB20-20

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 optional Shared Diagnostic Control Panel (SDCP).
The functionality of the SDCP is available by clicking on the function keys with the
mouse rather than by pressing keys on the SDCP.
Asynchronous Terminal Interface (ATI) Support
The DSU/CSU can be configured and managed from an asynchronous terminal.
The asynchronous 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 SDCP, but you do not have the
limitation of the 2-line, 16-character LCD.
Telnet Access
Remote asynchronous 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, LAN adapter, or network device can be directly connected
to the communications (COM) port.
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).
