1. GENERAL

This document provides installation and maintenance

procedures for the ADTRAN Total Access 4303 DS3

Module (P/N 1200332L1, see Figure 1).

Revision History

This is the second release of this practice. This version

includes general documentation updates and the

addition of the DS3 Menu Tree.

Description

The Total Access 4303 DS3 Module is a member of the

Total Access 4303 family of integrated access products.

It provides a single channelized DS3 interface. The

module terminates all 28 DS1s of a channelized DS3

into the Total Access 4303 TDM backplane for use in

GR-303 applications or in a DACS. Any of the 28 DS1

circuits or the DS3 receive clock can serve as the

primary or backup timing source for the entire system.

The DS3 Module combines with the Total Access 4303

base unit and other Total Access 4303 modules to

support requirements calling for multiple DSX-1

circuits.

Figure 1. Total Access 4303 DS3 Module

Typical applications calling for Total Access 4303 and

the DS3 Module include the following:

•GR-303

• Digital Access Cross Connect System (3/1/0

DACS). Any DS0 on any DS1 circuit can be

switched to any other DS0 on any other DS1 circuit.

• DS3 Bandwidth Management. A DS3 circuit carry-

ing voice, data, and other traffic can have its pay-

load groomed and directed to the appropriate

interface inside the Total Access 4303 system.

Features

The DS3 Module includes the following features:

• Provisioned by software only - no hardware

switches

• Local and remote line and payload loopbacks as

well as QRSS test pattern available per port

• Compliant with ANSI T1.102, ANSI T1.403,

AT&T 54016, and AT&T 62411

• Various timing options; automatically switches to

local timing if LOS is detected on selected timing

source

• Inherent DACS capability

• Extensive performance monitoring of the DS3 or

individual DS1 circuits

• DS3 maintenance data link support

• Software configurable line build out

• Meets NEBS Level 3 and UL 60950 standards

Functional Description

The DS3 Module will install into any of the first four

option slots (labeled 1 through 4) in the Total Access

4303 chassis. The status of the module can be viewed,

as well as the circuits to which it interfaces, via the

terminal menus. The terminal menus are accessible

through either a VT100 terminal connected to the Total

Access 4303 base unit’s control port or through a Telnet

session established through the base unit’s Ethernet

port. Use the terminal menu to configure the DS3

Module and to download application software.

The Total Access 4303 system is composed of a 19-inch

chassis housing, two power supplies, two SCUs, and

sixteen option slots. The DS3 Module’s physical

interface is provided on the Total Access 4303 chassis

backplane using the BNC Module (P/N 1200323L1).

The Total Access 4303 backplane delivers two

-48 VDC buses to the DS3 Module. The DS3 Module

operates with either or both buses active.

Physical Description

The front panel of the DS3 Module displays the module

name, part number, CLEI code and status LEDs. The

module name, part number, and CLEI code may also be

found through the terminal menus. The dimensions of

the card itself are approximately 6 inches in height, 0.88

inches in width, and 10 inches in depth.

Compliance

Table 1 shows the Compliance Codes for the Total

Access 4303 DS3 Module. The DS3 Module is NRTL

listed to the applicable UL standards. The DS3 Module

is to be installed in a restricted access location and in a

Type “B” or “E” enclosure only.

This device complies with Part 15 of the FCC rules.

Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received,

including interference that may cause undesired

operation.

Changes or modifications not expressly approved by

ADTRAN could void the user’s authority to operate this

equipment.

2. INSTALLATION

After unpacking the DS3 Module, inspect it for damage.

If damage has occurred, file a claim with the carrier,

then contact ADTRAN Customer Service (refer to

Warranty and Customer Service on page 11). If

possible, keep the original shipping container for

returning the DS3 Module for repair or for verification

of shipping damage.

Shipping Contents

The contents include the following items:

•DS3 Module

• DS3 Module Job Aid

Electronic modules can be damaged by static electrical

discharge. Before handling modules, wear an antistatic

wrist strap to prevent damage to electrical components.

Place modules in antistatic packing material when

transporting or storing.

Instructions for Installing the Module

Follow the steps below to install the module.

NOTE

Hot insertion of the module is permissable.

WARNING

Dangerous voltage is exposed when the cover

plate is removed.

SUBJECT TO ELECTROSTATIC DAMAGE

OR DECREASE IN RELIABILITY.

HANDLING PRECAUTIONS REQUIRED.

61200333L1-5B 3

1. If present, remove the cover plate from the appro-

priate option slot (labeled 1-4) of the Total Access

4303 chassis.

2. Position the module to fit in the lower and upper

grooves.

3. Slide the module into the option slot pressing

equally on the top and bottom of the front panel

until the module is firmly positioned against the

back of the chassis.

4. Push in the ejector on the lower left-hand side of

the module to finish seating the module.

Auto-detection of Modules

The Total Access 4303 SCU automatically detects the

presence of the DS3 Module when the module is

installed into the system. Rebooting is not required.

Wiring Connections

The DS3 physical interface is provided on the Total

Access 4303 chassis backplane using the BNC Module

(P/N 1200323L1). This module provides a dual 75-ohm

BNC connector.

Font Panel LEDs

See Table 2 for a description of the front panel LEDs.

3. PROVISIONING

The DS3 Module can be configured and controlled from

a variety of sources, including the following:

• The terminal menus, allowing detailed configura-

tion, status, and diagnostics

• SNMP, primarily for reporting alarm conditions

and system status (not currently supported)

NOTE

The remainder of this document describes the

menu items available when managing the DS3

Module via the terminal menus.

The Terminal Menus

The terminal menus are available by using either a

VT100 terminal attached to the Total Access 4303

active SCU’s craft port, the chassis’ ADMIN port, or a

Telnet session established through the SCU’s Ethernet

port. The Total Access 4303 System Manual, Section 6

(DLP-610) provides detailed instructions on using any

of these management approaches.

Terminal Menu Structure

The

Total Access 4303

uses a hierarchical menu

structure to provide access to all of its features. The top-

most menu level leads to submenus which are grouped

by functionality. All menu items display in the terminal

window. Figure 2 illustrates the DS3 menu tree.
