Introduction
QUAD Nx 56/64 MODULE OVERVIEW
The Quad Nx (pronounced “N-by”) 56/64 Module provides four synchronous V.35 DTE ports, each of which can operate at any rate that is a
multiple of 56 or 64 kbps, up to 1.536 Mbps. The Quad Nx 56/64 Module
can be installed in any option slot of the ATLAS chassis.
Features
• Each port operates using 1 to 24 DS0s
• 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)
Loopbacks can be invoked locally or remotely (V.54).
Interfaces
• CCITT V.35 electrical (differential)
• Connector: DB-37 (DB-37 to Dual Winchester V.35 connector adapter
cables are shipped with this module)

Physical Description
The Quad Nx 56/64 Module can plug into any available option slot in the
ATLAS 800 chassis (see Figure 1-1).
The module has an indication under each D-shell connector referring to
the port on the card.

Quad Nx 56/64 Module
Adapter Cable
Two ADTRAN-supplied adapter cables convert from the DB-37
connectors on the rear of the module to Dual Winchester V.35 connectors. These connectors are marked as 1/3 and 2/4 to represent
the port connected (1 or 3/2 or 4), based on which DB-37 the cable is
attached to.

Installation
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 use in shipping the option module back for repair
or for verification of damage during shipment.
