OVERVIEW

Introduction

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 oth­er traffic can have their payload gro omed and directed to the appropriate in­terface 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 multi­ple 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 infor­mation 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.

UNPACK AND INSPECT

Carefully inspect the Quad E1/PRA Module for any shipping damages. 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 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)

• One high-density to Quad DB-15 female cable (ADTRAN P/N 3125I061).

INSTALLING THE QUAD E1/PRA MODULE

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-

• 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 manage­ment 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

port

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.
