7-8 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.
