Introduction
DUAL NX 56/64 MODULE OVERVIEW
The Dual Nx (pronounced “N-by”) 56/64 Module provides two syn chro nous V.35 DTE ports, each of which can operate at any rate that is a multiple
of 56 or 64 kbps, up to 2.048 Mbps. The Dual Nx 56/64 M odule can be installed in any option slot of the ATLAS 550 chassis.
Features
• Operatesusing1to32DS0soneachport
• Includes an elastic store for absorption of rate variations
• Uses any port 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
• Uses bidirectional loopbacks:
- Port (toward the network)
-DTE(towardtheDTE)
Loopbacks can be invoked locally or remotely (V.54).
Interfaces
• Two V.35 Winchester connectors

The module has a label over each connector referring to the port on the card.
The four Option slots (labeled 1 — 4) only accept Option Modules,
and the Network Interface slots (labeled Network 1 and Network 2)
only accept Network Interface Modules. (See the ATLAS 550 in
Figure 2-1 on page 2-2.)

UNPACK AND INSPECT
Carefully inspect the option module for any shipping damage. If damage is
suspected, file a claim immediately with the carrier and 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 returning the option module for repair or for verificationof damage during shipment.

POWER-UP TESTING AND INITIALIZATION
The Dual Nx 56/64 Module executes a self-test during the power-up sequence, as descri bed in the ATLAS 550 User Manual. Upon power-up, any
previously configured setting for the Dual Nx 56/64 Module is automatically restored.
If the power-up self-test is not successful, refer to the Troubleshooting section
of the ATLAS 550 User Manual to diagnose and correct the problem.

OVERVIEW
Operation
The Dual Nx 56/64 Module can be configured and controlled as follows:
• Terminal menus - used for detailed configuration, status, and diagnostics
• SNMP, used primarily for reporting alarm conditions and system status
Theterminal menu is accessed using either a VT-100 terminal attached to the
ATLAS 550 Base Unit’s control port, or through a Telnet session established
through the Base Unit’sEthernetport. Detailed instructions on the operation
of each of the supported management approaches are presented in the
ATLAS 550 User Manual.
To edit items in the terminal menus, you must have the
appropriate password level. Each menu description in this
section indicates the password level required for write and read
access. See the section Access Passwords in the ATLAS 550
User Manual for detailed information on working with
passwords. Security level 1 users can view and edit every
available field. Security level 5 users can view any field but
cannot edit.
The remainder of this section describes the menu items presented when
managing the Dual Nx 56/64 Module using the terminal menus.

Appendix A. Dial Plan Interface Configuration
ID The Source ID field is used to simplify the creation of a Dial Plan in applica-
tions where the crit erion for switching calls to a certain endpoint is a function of which endpoint originated the call.
• Default value = 0. The default ID for all endpoints is 0 and for all accept
numbers is 0. With default values, all calls are routed based only on dialed num ber.
• Multiple endpoints can have the same Source ID.
• When creating the Call Accept list, specify a Source ID(s) as well as a dialed number or range of dialed numbers to accept.
Example: An application requires that all calls that originate from Port 1 of
the Dual Nx 56/64 Module in Slot 1 be switched to Port 2 of that same module. Assign a unique Source ID (e.g. 7) to Port 1 of the module, and then configure Port 2 to only accept calls from that unique Source ID (7).
