Chapter 1 Introduction
ATLAS QUAD USSI MODULE OVERVIEW
The ATLAS Quad USSI Module provides four synchronous DTE ports, each
of which can operate at any rate that is a multiple of 56 or 64 kbps, up to
2.048 Mbps. You can install the ATLAS Quad USSI Module into any avail-
able option slot of the ATLAS_800 chassis.
Features
• Each port operates using 1 to 32 time slots, each time slot being 56 or 64
kbps
• Includes an elastic store for absorption of rate variations
• Any port can be used as a timing source for the entire system
• Outputs a 50 percent duty-cycle output clock at all rates
• Generates and responds to V.54 looping codes
• Generates and checks 511 test patterns
• Bidirectional loopbacks:
- Port (toward the network)
- DTE (toward the DTE)
Interfaces
• EIA-530
• EIA-530A
•RS-449
•RS-232
• CCITT X.21 (V.11)
• Connector: DB-78
(DB-78 to Dual D sub connector adapter cables ship with this module.)
You can invoke loopbacks locally or remotely (V.54).

Physical Description
The ATLASQuad USSI Module can plug into any available option slot inthe
ATLAS_800 chassis (see Figure 1-1). The module has an indication under
each D-shell connector referring to the port on the card.
Figure 1-1. ATLAS Quad USSI Module
Adapter Cable
Two ADTRAN-supplied adapter cables convert from the DB-78 connectors
on the rear of the module to Dual D sub connectors. These connectors are
marked as 1/3 and 2/4to represent the port connected (1 or 3/2 or 4), based
on the cable to which the DB-78 attaches.

UNPACK AND INSPECT
Carefully inspect the option module for any shipping damage. If damage is
suspected, file a claim immediately with the carrier and then contact
ADTRAN Technical Support. (See the last page of this manual for
information on contacting Technical Support.) If possible, keep the original
shipping container for returning the option module to ADTRAN for repair
or for verification of damage during shipment.

Instructions for Installing the ATLAS Quad USSI Module
Step Action
1
Remove the cover plate (corresponding to the option slot
into which you want to install the ATLAS Quad USSI
Module) from the ATLAS 800 chassis rear panel.
Dangerous voltage is exposed when the cover plate is
removed.
2
Slide the ATLAS Quad USSI Module into the ATLAS 800
chassis until the module is positioned firmly against the
front of the ATLAS Base Unit.
3Using a screwdriver, tighten the thumbscrews at both
edges of the option module.
4Connect the cables to the associated device(s).
5
Complete installation of remaining modules and Base
Unit as specified in the Installation chapter of the ATLAS
800 User Manual.

Chapter 3 Operation
OVERVIEW
You can configure and control the ATLASQuad USSI Module from a variety
of sources, including the following:
• The ATLAS Front Panel provides minimal configuration and status sup-
port.
• The terminal menu allows detailed configuration, status, and diagnos-
tics.
You can access the terminal menu from either a VT-100 terminal attached to
the ATLAS Base Unit’s control port, or through a Telnet session established
through theBase Unit’s Ethernet port. ATLASUserManual provides detailed
instructions on operating each of the supported management approaches.
PASSWORD SECURITY LEVELS
To edit items in the terminal menu, you must have the appropriate pass-
word level. Each menu description in this section indicates the required
password level required for write and read access. ATLAS security levels
range from level 5 (most restrictive) through level 0 (most permissive). See
the section Access Passwords in the ATLAS 800 User Manual for detailed infor-
mation on working with passwords.
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 (see
Figure 3-1). All menu items display in the terminal window.
This chapter describes the menu items presented when managing
the ATLAS Quad USSI Module via the terminal menus.

Chapter 3. Operation
3-2 ATLAS Quad USSI Module User Manual 61200261L1-1
Figure 3-1. Menu Tree
The ATLAS System Controller automatically detects the presence of the AT-
LAS Quad USSI Modulewhen it is installed in the system. To see the menus
for the ATLAS Quad USSI Module via the terminal menu, use the arrow
keys to scroll to the Modules menu and press Enter to access the module
choices (see Figure 3-2). The following sections describe all of these menu
options.
Refer to the ATLAS 800 User Manual for detailed instructions on
how to navigate through the terminal menu.

MENU DESCRIPTIONS
>SLT Read security: 5
Displays the number of available slots in the ATLAS chassis. Slot 0 refers to
the ATLAS Base Unit. This field is read-only.
>TYPE Write security: 3; Read security: 5
Displays the type of module actually installed in the slot or the type of
module you plan to install in the slot. If an ATLAS Quad USSI Module is
installed, the Type field automatically defaults to USSI (the ATLAS Quad
USSI Module). You can use this field to preconfigure a system before actu-
ally installing modules by simply specifying the module that you want to
install in each slot.
To help you follow the terminal menu hierarchy, the following notations are used.
>MAIN MENUS
» Submenus
»» Sub-submenus
If you install a module in a slot, then want to install a different type
of module in the slot, you must set this field to Empty before
selecting another module type.
If a module is installed, Type automatically displays the name of
the installed module, and cannot be set to any other option.

Module. Press Enter in this field to activate the Alarm menu.
>TEST Read security: 5
Displays whether the ATLAS Quad USSI Module is executing a test. Press
Enter in this field to activate the Test menu.
>STATE Write security: 3; Read security: 5
Allows an installed module to be marked Offline, which may be useful in
system troubleshooting. Although a module is physically installed, it must
be marked Online for it to be considered an available resource.
>STATUS Read security: 5
This is a read-only field presenting status information on the ATLAS Quad
USSI Module. The following messages may display:
>REV Read security: 5
(Hardware Revision) Displays the hardware revision of the ATLAS Quad
USSI Module. This is a read-only field.
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 en-
abled for this option slot.
Offline The module is installed, but has been taken Offline by a us-
er. The module is still responding to controller polls.
Offline/
No Response The module is installed, but has been taken Offline by a us-
er. The module is not responding to polls.
Not Supported The module is not supported by the current ATLAS Base
Unit.
