1. GENERAL

This document provides installation and maintenance

procedures for the ADTRAN Total Access 4303 STS-1

Module (P/N 1200352L1, see Figure 1).

Revision History

This is the second release of this practice. This version

includes general documenation updates and the addition

of the STS-1 Menu Tree.

Description

The Total Access 4303 STS-1 Module is a member of

the Total Access 4303 family of integrated access

products. It provides a Synchronous Optical Network

(SONET) STS-1 interface. The module terminates up to

28 asynchronous DS1 signals from the SONET STS-1

signal using VT 1.5 channels. All of the bandwidth of

the 28 DS1 signals is available to other TDM resources

in the system at the DS0 level.

The STS-1 Module combines with the Total Access

4303 base unit and other Total Access 4303 modules to

support requirements calling for multiple DS1 circuits

on an STS-1 interface.

Figure 1. Total Access 4303 STS-1 Module

Typical applications calling for Total Access 4303 and

the STS-1 Module include the following:

•GR-303

• Multiplexes/Demultiplexes STS-1 signal into 28

DS1 channels.

• Full grooming of VT 1.5s within the STS-1 to

DS1s.

Features

The STS-1 Module includes the following features:

• Software provisioned 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, and

Bellcore GR-253.

• Loop, free run and external DS1 timing modes

• Inherent DACS capability

• Extensive performance monitoring of the STS-1 or

individual DS1 circuits

• Embedded Operations Channel (EOC) and Time

slot Management Channel (TMC) support

• Software configurable line build out

• Meets NEBS Level 3 and UL 60950 standards

2 61200352L1-5B

Functional Description

The STS-1 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 STS-1

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 STS-1 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 STS-1 Module. The STS-1

Module operates with either or both buses active.

Physical Description

The front panel of the STS-1 Module displays the

module name, part number, 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, 8.8

inches in width, and 10 inches in depth.

Compliance

Table 1 shows the Compliance Codes for the Total

Access 4303 STS-1 Module. The STS-1 Module is

NRTL listed to the applicable UL standards. The STS-1

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 STS-1 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 STS-1 Module for repair or for

verification of shipping damage.

Shipping Contents

The contents include the following items:

• STS-1 Module

• STS-1 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.

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 STS-1 Module when the module is

installed into the system. Rebooting is not required.

Wiring Connections

The STS-1 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.

Front Panel LEDs

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

3. PROVISIONING

The STS-1 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 DS1 alarm condi-

tions and system status

NOTE

The remainder of this document describes the

menu items available when managing the

STS-1 Module via the terminal menus.

The Terminal Menus

The terminal menus are available by using either a

VT-100 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 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.

Accessing the Module Terminal Menus

Once connected to a terminal, press

Enter

several times

until a

OGIN

prompt displays. Enter the default

password, password, in lowercase characters (the login

system is case sensitive). The Total Access 4303 upper-

level

YSTEM

NFO

menu opens. Figure 2 illustrates the

STS-1 menu tree.

The module is enabled and is responding to the sys-

tem controller’s status polls. This is the normal re-

sponse of the system.

ESPONSE

The module is enabled, but is not responding to the

system controller’s status polls. This response indi-

cates either a problem in the system or that the mod-

ule is not installed.

MPTY

The system controller has not detected the presence

The module is installed, but has been taken offline

by a user. The module is still responding to control-

ler polls.

submenu displays per-DS0 alarm

status; that is, at least one DS0 channel is in alarm if an

asterisk (*) appears. These alarms usually indicate the

failure to receive the protocol that has been configured

for the DS0.

TATUS

Read security: 5

display for those DS0s where robbed bit signaling

(RBS) is not being transferred by Total Access 4303.

measures as specified in ANSI T1.403 and AT&T

TR54016 for each of the T1/DSX-1 ports. Except for

CLR, these fields are all read-only. The monitored

parameters include the following:

•

- Displays the number of the DS1 circuit (1-28)

•

- Clears performance information for the se-

lected port

•

ES - An ES (Errored Seconds) is a second with one

or more error events OR one or more OOF events

OR one or more Controlled Slip Seconds (CSS)

•

BES - A BES (Bursty Errored Seconds) is a second

with more than one, but less than 320 error events

•

SES - An SES (Severely Errored Seconds) is a sec-

ond with 320 or more error events OR one or more

OOF events

•

SEFS - Severely Errored Frame Seconds

•

LOFC - Loss of Frame Count

•

CSS

- Controlled Slip Seconds

•

UAS - Unavailable Seconds

•

PCV - Path Code Violations
