TSU 100 User Manual 61202052L1-1

A test pattern is sent from the controller through a loop-back on

all other boards and is checked on the controller. This verifies

the data path, clocks, and control signals.

If a failure is detected, note the failure number prior to contact-

ing ADTRAN Technical Support.

Executing the self-test will disrupt normal data flow and pre-

vent remote communication until it is completed.

Port Tests

The Port Tests Menu is used to activate testing of specific data

ports. It controls the activation of loop-backs and the initiation

of data test patterns. Test results are displayed in the LCD win-

dow.

The execution of Port Tests will disrupt normal data flow in the

port being tested.

Port Test Menu Items for 0.1 Nx56/64

0.1 Nx DBU is the base Nx interface. It offers the following test

functions:

DTE Loop-Back

This initiates a loop-back. The following options are available:

The TSU 100 checks the remote loop-back activation by detecting

a proper response from the remote end. While waiting for the re-

sponse, the display shows Looping. If successful, the display

changes to Looped-Up. If unsuccessful, the display shows Failed.

PORT/

LOCAL

The Nx port activates both a Local loop-back

(back toward the DTE) and a Port loop-back when

either is invoked.

REMOTE The remote loop-back causes a V.54 code to be

sent to the far end. The Nx at the far end activates

a PRT/LCL loop-back upon detection of the V.54

code.

OFF The loop is deactivated.
