Chapter 1 Introduction
OVERVIEW
The Nx56/64 (EIA-530) option module is one of the option modules available for use with the ADTRAN TSU
100, 120, 600, and 610. The Nx56/64 (EIA-530) option
module installs in the option slot of the TSU 100 and provides an additional synchronous EIA-530 interface port.
When used in the TSU, this interface port allows an additional DTE to have access to the T1 service.
Functional Description
The Nx56/64 (EIA-530) interface operates in the option
slot of the TSUs, or as a plug-on to any option module and
is under the control of the TSU. The Nx56/64 (EIA-530)
option module is configured from the front panel or by an
external PC program. The internal menus for its configuration are part of the Nx card and are automatically installed when the option module is plugged into the TSU.

Figure 1-1. Nx56/64 (EIA-530) Option Module
The rear panel of the option module includes a plastic
plug over a cutout for a second EIA-530 connector. This
allows the addition of another plug-on module. The port
X.1
and
X.2
indication is linked to the port numbering
philosophy of the TSU 100 product family. The X represents the slot number, into which the option module is
plugged. For the TSU 100, there is only one option slot.
Therefore, the port designation would be

UNPACK & INSPECT
Carefully inspect the Nx56/64 (EIA 530) option module
for any shipping damage. If damage is suspected, file a
claim immediately with the carrier and then contact
ADTRAN customer service. If possible, keep the original
shipping container for use in shipping the module back
for repair or for verification of damage during shipment.

Chapter 2. Installation
INSTALLING THE OPTION MODULE
Power to the TSU 100 should be Off when installing any option module .
Placement of the Option Module
Figure 2-1 shows the proper placement of the option
module. To install the option module, perform the following steps:
1. Remove the cover plate from the TSU 100 rear panel.
2. Slide the option module into the rear panel of the
TSU 100 until it is positioned firmly against the front
of the unit.
3. Fasten the thumbscrews at both edges of the option
module.

Power Connection
Each option module derives power from the base TSU 100
unit. Power to the TSU 100 is supplied by a captive eightfoot power cord.
Attaching the Plug-on Board
Figure 2-2 shows the proper attachment of a plug-on
board to the option module. Perform the following steps
to install the plug-on board:
1. Hold the plug-on board above the option module.
2. Using a downward and right to left motion , slip the
DTE connector plug into the opening in the option
module back panel.
3. Move the plug-on board downward then secure the
connection of the header pins at the front of the
boards.
4. Install the two 4-40 screws at both edges of the
option module.

POWER-UP AND INITIALIZATION
The Nx56/64 (EIA-530) option module executes a self-test
during the power-up sequence, as described in the TSU
100 User Manual. No initialization input is required. Upon
power-up, any previously configured setting for the
Nx56/64 (EIA-530) option module is automatically restored.
When the self-test is complete and the configuration is
successfully restored, the LED labeled OK in the module
group on the front panel turns ON. For more information,
see Front Panel Operation in Chapter 3, Operation, of the
TSU 100 User Manual. If any alarms are detected during
operation, the red LED labeled
group on the front pane l turns ON.

3)PORT TEST, Submenu of 4)Test
This menu item is used to activate testing of specific data
ports. It also controls the activation of loopbacks and the
initiation of data test patterns. Test results are shown on
the TSU 100 disp lay.
The execution of port tests disrupts normal data flow in the port being
tested.

The Nx interface offers the following test functions:
1)LOOPBK: Initiates a loopback.
PRT/LCL: The Nx port activates both a local loopback (back toward the DTE) and a port loopback
when either is invoked. See Chapter 1, Introduction,
of the TSU 100 User Manual, for more information.
Remote: The remote loopback causes a V.54 code to
be sent to the far end. The Nx at the far end activates
a PRT/LCL loopback on detection of the V.54 code.
Off: The loop is deactivated.

Chapter 3. Operation
The TSU 100 checks the remote loopback activation by detecting a proper
response from the remote end. While waiting for the response, the display
shows Looping. If successful, the display changes to Looped Up. If
unsuccessful, the display shows Failed.
2)511 PATT: Activates the generation of the 511 test pattern.
On: The pattern check circuitry is enabled and a test
started. The test is ended by selecting Off.
Off: The pattern generation and check is disabled.
3)DIS 511 RESLT: Displays the results of the 511 test
indicated in item 2, above. The results are in the form of
the number of errored seconds. The error count can be
cleared by pressing
Clear (shift + 9).
