DS1-BD (DS1 Interface Circuit Pack)
End Loopback/Span Test (#1216)
This test is destructive.
The End Loopback/Span test deactivates an active loop-back or span test on a
TN767E DS1 circuit pack. Bit error counting against the received test pattern
stream halts, and sending of the framed 3-in-24 test pattern ceases. If either the
CPE loop-back jack or the far-end CSU is looped, the appropriate loop-back
deactivate code is sent. If the loop back could not be deactivated, then the test
will FAIL and a MINOR alarm will be noted in the alarm log until the loop back is
cleared.
The test is highly destructive and can only be initiated by a technician-demanded
test ds1-loop UUCSS end-loopback/span-test command. Since only one of
these three different long-duration loop-back/span tests can be active at a time,
the TN767E circuit pack knows which loop-back/span test to halt.
All trunks or ports on the DS1 Interface circuit pack must be busied out via the
system technician busyout board command before running this End
Loopback/Span test.
The list measurements ds1 summary command will display the length of time
the test ran (Test Duration field) and number of bit errors detected
(Loopback/Span Test Bit-Error Count field).
To restore the trunks or ports on the TN767E DS1 Interface circuit pack to the
in-service state, execute the release board command.
