FAIL
(cont’d.)
6. If the result of Test #110 is FAIL and the result of Test #111 is PASS for
the target DATA-CHL, then the mos t likely problem is that the TDM Bus or
Tone-Clock circuit pack is defective.
■Check for the existence of TDM Bus (TDM-BUS) and/or Tone-Clock
circuit pack (TONE-BD, TONE-PT, and TDM-CLK) errors a nd alarms.
If they exist:
a. Refer to the corresponding Maintenanc e documentation to
clear the errors and alar ms.
b. Repeat the test.
■If TDM Bus (TDM-BUS) and/or Tone-Clock circuit pack (TONE-BD,
TONE-PT, and TDM-CLK) errors and alarms do not exist, investigate
the possibility that the target DATA-CHL, or the P r ocessor circuit pack
is defective as described in Step 6.
7. If the result of Test #110 is eith er PASS or FAIL and the result of test #111
is FAIL for the target DATA-CHL, then the most likely problem is that the
target DATA-CHL is defective, or the Processor circuit pack is defective.
■Busyout all functions that are using the Data Channels (DATA-CHLs).
!CAUTION:
All functions must be busied out because Test #107 is destructive and terminates all established connections over the DATA-CHLs.
■Issue the test data-module <ext> long for the target DATA-CHL.
Note the test results for Test #107 and #108.
a. If the result of Test #107 is FAIL, then the Processor circuit pack
is defective.
■Replace the Processor circuit pack at your earliest convenience.
After the Processor circuit pack has been replaced, its Time-of-Day
clock must be set using the set time command.
■Repeat the test.
b. If the result of Test #107 is PASS and the result of Test #108 is
FAIL, then the Processor circuit pack is defective.
■Although all DATA-CHLs are unusable, the SW-CTL is still
operational. Based on the customer’s use of DATA-CHLs, r e place the
Processor circuit pack at the customer’s convenience. After the
Processor circuit pa ck has been replaced , its Time-of-Day clock must
be set using the set time command.
■Repeat the test.
