DS1-BD (DS1 Interface Circuit Pack)
If a TN767E circuit pack detects certain I-CSU/T1 Sync Splitter hardware errors, it
will notify maintenance. When the maintenance subsystem receives notification of
the error, it will execute this Loss of Signal Inquiry test. The test, in addition to
querying for a Loss Of Signal alarm condition, will also query the TN767E board to
confirm the error. A Minor or Warning alarm will be raised depending on the
severity of the error. The trunks on the board may be taken out of service if the
error is deemed serious.
If a Loss Of Signal alarm and an I-CSU/T1 Sync Splitter error co-exist, the Loss Of
Signal alarm condition will take priority and the board and all trunks on the board
will be put in the out-of-service state. Errors will be logged, however, for both.
When the maintenance subsystem receives notification that the ICSU/T1 Sync
Splitter hardware error condition no longer exists, maintenance will restore the
board and all trunks to their previous service state if the alarm can be cleared (no
other errors or Loss Of Signal alarm exist).
