6. If the result of Test #110 is either 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, 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.
■ 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 TN777 Network
Control circuit pack is defective.
■ 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.
■ 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.
■ 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.
■ Repeat the test.

If the result of Test #107 is PASS and the result of Test #108 is PASS, then the
target DATA-CHL is defective.

remove it from operation.
■ 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.
