Chapter 1 Introduction
OVERVIEW
The Quad E1/PRA Module is a member of the ATLAS family of Integrated
Access products and provides four channelized E1 or Primary Rate Access
(PRA) interfaces. Using the available converter assembly (P/N 1200209L1),
each interface impedance can be independently selected, and any port can serve
as the primary or backup timing source for the entire system.
The Quad E1/PRA Module combines with the ATLAS base unit and other
ATLAS modules to support requirements calling for multiple E1 and/or PRA
circuits. As many Quad E1/PRA Modules can be installed in a system as can be
physically accommodated in the ATLAS chassis.
Typical applications calling for ATLAS and the Quad E1/PRA Module include
the following:
• Digital Access Cross Connect System (DACS). Any TS0 on any E1 circuit can
be switched to any other TS0 on any other E1 circuit.
• E1 Bandwidth Management. E1 circuits carrying voice, data, video, and oth-
er traffic can have their payload groomed and directed to the appropriate in-
terface inside the ATLAS system.
• Digital Circuit Provisioning. When combined with the Octal BRI/U Module
(P/N 1200186L1), the Quad E1/PRA Module can combine data from multi-
ple dedicated-bandwidth U-interfaces into a single E1.
Figure 1-1 shows the E1 bandwidth management application.

FUNCTIONAL DESCRIPTION
The Quad E1/PRA 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 infor-
mation is available via the terminal menu, which is accessible through either a
VT 100 terminal connected to the ATLAS Base Unit’s control port or through a
Telnet session established through the base unit’s Ethernet port. The Quad E1/
PRA Module can be configured and application software can be downloaded
using the terminal menu.
Features
• Four E1 interfaces
• Each interface configurable for 75-ohm unbalanced, 120-ohm balanced, or

UNPACK AND INSPECT
Carefully inspect the Quad E1/PRA Module for any shipping damages. If dam-
age is suspected, file a claim immediately with the carrier and then contact
ADTRAN Technical Support (see the last page of this manual for pertinent
information). If possible, keep the original shipping container for shipping the
Quad E1/PRA Module back for repair or for verification of damage during
shipment.
Shipping Contents
The following items are included in the ADTRAN shipment:
• Quad E1/PRA Module
• Quad E1/PRA Module User Manual (to be inserted into the ATLAS User
Manual)

INSTALLING THE QUAD E1/PRA MODULE
Figure 2-1 represents the action required for proper placement of the Quad E1/
PRA Module, as described here:
Instructions for Installing the Quad E1/PRA Module
Step Action
1Remove the cover plate from the appropriate option slot of the
ATLAS 800 or 800
PLUS
rear panel.
2Slide the Quad E1/PRA Module into the option slot until the
module is firmly positioned against the front of the chassis.
3Use a screwdriver to tighten the thumbscrews at both edges of
the module.
To ensure that the thumbscrews are securely fastened, use a
screwdriver to tighten them.

Chapter 3 Operation
OVERVIEW
The Quad E1/PRA Module can be configured and controlled from a variety of
sources, including the following:
• The ATLAS front panel, providing minimal configuration and status sup-
port
• The terminal menu, allowing detailed configuration, status, and diagnostics
• SNMP, used primarily for reporting alarm conditions and system status
You can access the terminal menu using either a VT-100 terminal attached to the
ATLAS Base Unit’s control port or a Telnet session established through the Base
Unit’s Ethernet port. Detailed instructions on each of the supported manage-
ment approaches are presented in the ATLAS User Manual. The remainder of
this section describes the menu items available when managing the Quad E1/
PRA Module via the terminal menu.
Security Passwords
To edit items in the terminal menu, you must have the appropriate password
level. Each menu description in this section indicates the password level
required for write and read access. See “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 5 users can view any field but cannot edit.
TERMINAL MENU STRUCTURE
ATLAS uses a form of hierarchical menus to access all features. The topmost
menu level leads to submenus which are grouped by functionality. All menu
items display in the terminal window.
Refer to the ATLAS User Manual for detailed instructions on navigating
through the terminal menu.

Chapter 3. Operation
3-2 Quad E1/PRA Module User Manual 61200264L1
The ATLAS system controller automatically detects the presence of the Quad
E1/PRA Module when it is installed in the system. To see the menus for the
Quad E1/PRA Module via the terminal menu, use the arrow keys to scroll to
the
Modules
menu and press
Enter
to access the module choices. Figure 3-1
shows the
Modules
menu. The following sections describe all the ATLAS
Mod-
ules
menu options.
Figure 3-1. Modules Menu
MENU DESCRIPTION
>SLT Read security: 5
(Slot) Displays the number of available option 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 a Quad E1/PRA Module is installed, the
Type
field automatically defaults to
E1/PRI-4
(the Quad E1/PRI Module). You can
use this field to preconfigure a system before installing modules by specifying
the module that you want to install into each slot.
To help you follow the terminal menu hierarchy, the following notations are
used.
