DATA-CON 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.
3. Issue the test data-module <ext> long command for the target
DATA-CHL. Note the test results for Tests #107 and #108.
a. If the result of Test #107 is FAIL, then the TN777 Network Control
circuit pack is defective.
1. 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.
2. Repeat the test.
b. If the result of Test #107 is PASS and the result of Test #108 is FAIL,
then the DATA-CON is defective.
1. 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.
2. Repeat the test.
FAIL c. If the result of Test #107 is PASS and the result of Test #108 is
PASS, then the target DATA-CHL is defective.
1. Issue the remove data-module command.
■ Replace the Network Control circuit pack at your earliest
convenience. After the TN777 Network Control circuit pack
has been replaced, its Time-of-Day clock must be set using
the set time command.
2. 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.
PASS The target DATA-CHL and DATA-CON are functioning. Connections can be
established over the target DATA-CHL.
