Chapter 1 Introduction
T3 MODULE OVERVIEW
The T3 Module and the T3 D/I (Drop and Insert) Module are members of the
ATLAS family of integrated access products providing one or two channelized T3
interfaces. The T3 Module combines with the ATLAS Base Unit and other ATLAS
modules to support requirements calling for delivery of multiple T1 circuits. The
modules terminate all 28 T1s of a channelized T3 into the ATLAS TDM Backplane
for use in dedicated or switched services. The T3 module has a DSX-3 level phys-
ical interface and the T3 D/I module has two T3 interfaces. The T3 D/I module
may terminate between 2 and 28 T1s as the T3 into the ATLAS and pass through
the remaining bandwidth out of the secondary T3 port. The secondary T3 port
may not be used to terminate bandwidth on the ATLAS, but passes the T1s back
out the primary T3 interface. Timing for the ATLAS may be sourced from the T3
module. The timing sources available from within the T3 module are any of its
odd numbered T1s (1-27), the internal 44.736 MHz oscillator (STRATUM 4), or the
T3 receive clock. The T3 module supports dedicated T1 links as well as robbed-bit
switched terminations.
Typical applications calling for ATLAS and the T3 Module include the following:
• Digital Access Cross Connect System (3/1/0 DACS). Any DS0 on any T1 cir-
cuit delivered on the T3 can be switched to any other DS0 on any other circuit.
• T3 BandwidthManagement. A T3 circuit carrying voice, data, video, and other
traffic can have its payload groomed and directed to the appropriate interface
inside the ATLAS system.
Figure 1-1 on page 1-2 shows the T3 bandwidth management application.

FUNCTIONAL DESCRIPTION
The T3 Module can be installed in any available option slot in the ATLAS chassis.
The status of the module itself, as well as the circuits to which it interfaces, can be
viewed from the ATLAS front panel. Additional status information is available
via the terminal menu (accessible through either a VT-100 terminal connected to
the ATLAS 800 Base Unit’s control port or through a Telnet session established
through the Base Unit’s Ethernet port). The T3 Module can be configured and
application software can be downloaded using the terminal menu.
Features
• Channelized T3 network interface
• Optional second T3 interface for drop and insert applications
• Cross-connect, drop and insert to the DS0 level (3/1/0 DCAS)
• Extensive performance monitoring of the DS3 or individual T1 circuits
• Software configurable line build-out
• T3 maintenance data link support
• Hot swappable
• 5-year warranty

UNPACK AND INSPECT
Carefully inspect the T3 Module for any shipping damages. If damage is sus-
pected, file a claim immediately with the carrier and then contact ADTRAN Tech-
nical Support (see the last page of this manual for pertinent information). If
possible, keep the original shipping container for returning the T3 Module for
repair or for verification of damage during shipment.
Contents of ADTRAN Shipment
The following items are included in the ADTRAN shipment:
• T3 Module
•T3 Module User Manual (to be inserted into the ATLAS 800 User Manual)
• Two six-foot long BNC-BNC (male) cables
INSTALLING THE T3 MODULE
Figure 2-1 represents the action required for proper placement of the T3 Module,
as described here:
1. Remove the option slot cover plate from the ATLAS 800 rear panel.
2. Slide the T3 Module into the option slot until the module is firmly positioned
against the front of the chassis.
3. Fasten the thumbscrews at both edges of the T3 Module.

WIRING
Each port of the T3 Module provides a pair of BNC connectors for connecting to
the T3 circuit. Table 2-1 describes the network connection.
POWER UP AND INITIALIZATION
The T3 Module automatically executes a self-test when it powers up. Any previ-
ously configured setting for the T3 Module is automatically restored upon power
up. If the T3 Module fails one or more of the self-tests executed during power up,
an error message is displayed on the LCD.

Chapter 3 Operation
OVERVIEW
The ATLAS System Controller automatically detects the presence of the T3 Mod-
ule when it is installed in the system. You can configure and control the T3 Mod-
ule from several sources. Table 3-1 shows the various sources, their purpose, and
their access. The ATLAS 800 User Manual provides detailed instructions on oper-
ating each of these supported management approaches. The remainder of this
chapter describes the menu items available for managing the T3 Module using the
terminal menu.
You must have the appropriate password level to edit items using the termi-
nal menu. (See the section Access Passwords in the ATLAS User Manual
for detailed information on working with passwords.)
Security level 0 users can view and edit every available field. Security level
5users can view any field, but they cannot edit.
TERMINAL MENU STRUCTURE
The ATLAS 800 uses hierarchical menus to access 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. You can use the Modules terminal menu to
configure and control the T3 Module (see Figure 3-1 on page 3-2).

MENU ACCESS
To access the Modules menu and submenus, use the keyboard arrow keys to
scroll to the appropriate row and column; then press ENTER on the keyboard.
For example, to view the Menu submenus for T3-2 (as shown in Figure 3-1), use
the keyboard arrow keys to scroll down to Modules, right to T3-2, and right again
to the Menu column; then press ENTER.
Refer to the Atlas 800 User Manual for detailed instruction on navigating
through the terminal menu.
T3 MODULE MENU DESCRIPTIONS
The following paragraphs (Slt (slot), Type, Menu, Alarm, Test, State, Status, and
Rev (revision)) describe the Modules menus and submenus. Unless a write secu-
rity-level is given, all menus and submenus are read-only.
Slt (slot)
Read security: 5
Displays the number of available option slots in the ATLAS 800 chassis. Slot 0
refers to the ATLAS 800 Base Unit.
Type
Write security: 3; Read security: 5
Displays the type of module currently installed in the slot or the module type you
plan to install in the slot. For instance, if a T3 Module is installed, the Type field
automatically defaults to T3-1 or T3-2. You can use this field to preconfigure a sys-
tem before installing modules; simply specify the module that you want to install
into each slot.
If a module is installed, Type automatically displays the name of the in-
stalled module, and it cannot be set to any other option.

Chapter 3. Operation
61200223L1-1 T3 Module User Manual 3-3
Menu
Displays additional status and configuration menus for the selected module. (See
“T3 Module Modules Submenus” on page 3-4 for detailed information on each
submenu.)
Alarm
Read security: 5
Displays whether there is an alarm condition on the T3 Module.
Test
Read security: 5
Displays whether the T3 Module is executing a test.
State
Write security: 3; Read security: 5
Displays whether the module is online or offline. Even though a module is physi-
cally installed, it must be marked Online for it to be considered an available
resource. This field allows an installed module to be marked Offline, which may
be useful in system troubleshooting. If you choose Offline, the module will not be
in alarm condition, but will display Offline.
A module must be in the Online state in order for ATLAS to use the module
for any data bandwidth.
Status
Read security: 5
Displays status information on the T3 Module. Table 3-2 on page 3-3 describes sta-
tus messages that may display.
Rev (Hardware Revision)
Read security: 5
Displays the hardware revision of the T3 Module.
Table 3-2. Status Messages
Message Meaning
Online The module is enabled and is responding to the system controller’s status
polls. This is the normal response of the system.
No
Response
The module is enabled, but is not responding to the system controller’s
status polls. This response indicates either a problem in the system or that
the module is not installed.
Empty The system controller has not detected the presence of a module in the slot,
nor has a module been manually enabled for this option slot.
Offline The module is installed, but has been taken Offline by a user. The module is
still responding to controller polls.
