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

Installation and Maintenance Practice
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
L
OGIN
prompt displays. Enter the default
password, password, in lowercase characters (the login
system is case sensitive). The Total Access 4303 upper-
level
