4. If the result of Test #111 is FAIL, then the most likely problem is that the
target DATA-CHL is defective, the DATA-CON is defective, or the TN777
Network Control circuit pack is defective. Busyout all functions that are
using the Network Control 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.
a. Issue the test data-module <ext> long command for the target
DATA-CHL. Note the test results for Tests #107 and #108.
1. If the result of Test #107 is FAIL, then the TN777 Network Control
circuit pack is defective.
(a).Replace the Network Control circuit pack immediately. After
the Network Control circuit pack has been replaced, its
Time-of-Day clock must be set using the set time
command.
(b).Repeat the test.
2. If the result of Test #107 is PASS and the result of Test #108 is
FAIL, then the DATA-CON is defective.
(a).Although all DATA-CHLs are unusable, the SW-CTL is still
operational. Based on the customer’s use of DATA-CHLs,
replace the Network Control circuit pack at the customer’s
convenience. After the Network Control circuit pack has
been replaced, its Time-of-Day clock must be set using the
set time command.
(b).Repeat the test.
3. If the result of Test #107 is PASS and the result of Test #108 is
PASS, then the target DATA-CHL is defective.
(a).Issue the remove data-module <ext> command for the
target DATA-CHL to remove it from operation.
(b).Replace the Network Control circuit pack at your earliest
convenience. After the Network Control circuit pack has
been replaced, its Time-of-Day clock must be set using the
set time command.
5. Restore any busied out function (PRI-CDR/SEC-CDR, SYS-PRNT,
PMS-PRNT/JNL-PRNT, PMS-LINK) to service before moving on to
another activity.
