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 imm ediate ly. 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.
