Introduction

Overview

The ACCULINKR 3166 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

Installation Manual

COMSPHERE 3000 Series Carrier

Features

The DSU/CSU optimizes network performance with a wide range of features such as the following:

H Software configuration menu displayed via an optional 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 Alarm message display/print capability. H Front panel emulation via Windows-based Front Panel Emulation software. H Asynchronous (async) terminal interface support. H Telnet access for remote async terminal operations. H Network management provided through industry-standard Simple Network

Management Protocol (SNMP).

Introduction

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).

For a complete listing of the safety instructions, see at the beginning of this guide.

HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from damage due to electrostatic discharge (ESD) during normal operation. When performing installation procedures, however, take proper static control precautions to prevent damage to equipment. If you are not sure of the proper static control precautions, contact your nearest sales or service representative.

Installation

 Pr ocedure

To install the DSU and rear connector module:

1. At the rear of the carrier, set the tab on the rear connector module into one of the slotted grooves on the carrier’s backplane. Loosely fasten the screws. Make sure the rear connector module uses the same slot position intended for the DSU.

NOTE:

If an auxiliary backplane for Models 3151 or 3161 DSUs is installed in the same carrier, verify that it is mounted over slots 9–16. Slot 9 is rendered inaccessible if the auxiliary backplane is mounted over slots 1–8.

4. At the front of the carrier, hold the DSU vertically with the latch on its faceplate in the open position. Then, insert the circuit card into the top and bottom circuit card guides for the slot that contains the rear connector module.

5. Slide the DSU/CSU into the slot, aligning the circuit card with the rear connector module, until the connectors seat firmly into the back of the carrier. Press the faceplate latch to secure the DSU/CSU into the carrier, rotate the circuit pack lock into the closed position, and tighten the screw.

SDCP Operation

Overview

This chapter contains information for operating your DSU/CSU using the optional Shared Diagnostic Control Panel of the 3000 Series Carrier. It includes a description of the SDCP and sample procedures for configuring the DSU/CSU.

Using the SDCP

For more information about the SDCP, refer to the

Carrier Installation Manual

The SDCP (Figure 3-1) contains a Liquid Crystal Display (LCD) and a keypad.

SDCP Operation

LCD

The LCD is used to display two types of data:

 Messages such as alarms, command/test completion, and action in progress

Keypad

 SDCP menu tree information (see Appendix A,

SDCP Menu

)

The LCD displays status messages as requested via the Device Health and Status branch of the SDCP menu (see

Monitoring and Testing

). In addition, the highest level status message appears on

Device Health and Status

in Chapter 4,

the front panel automatically if no front panel action has occurred at the DSU/CSU for the past five minutes.

The LCD also lists commands, configuration options, and test results. In most cases, the top line shows the command or option name and default value, while the second line displays options and responses. When a response is required, select from the options displayed directly above the Function keys (F1, F2, F3); make your choice by pressing the corresponding Function key.

The 7-button keypad enables you to navigate through the menu tree and select choices presented on the second line of the LCD.

Use the

key to move up the menu.

F1 F2

Use the key to exit any part of the menu in which you may be operating. You immediately return to the top-level menu screen (see Appendix A,

SDCP Menu

unless you are editing configuration options. If there are unsaved changes, the

key invokes the Save Edit screen.

SDCP Operation

Use the Function (F1, F2, F3) keys to make selections from the choices presented on the second line of the LCD. When this line presents choices, it is generally divided into three sections, each displayed directly above one of the Function keys. When your choice appears above one of the Function keys, press that key to select that choice.

The scroll keys ( and ) serve one of two functions, depending on whether a menu screen or a data entry screen appears on the front panel.

For data entry screens, the the

key scrolls one character to the right.

For menu screens, the

key scrolls to the next menu choice.

the
