SCOTCH Synchronous Loop-Around Test (#1275)
This test is destructive.
This test verifies the circuit in the data path of a PPP call. This test fails if the data transmitted on
the port does not match the data received in the loop-around mode. Failure of this test indicates
a port hardware fault on the circuit pack.
This test aborts if calls are using the port, or if the PPP link associated with the port is
connected. To avoid this, first enter busyout data-module extension, or busyout port
location, or busyout link link#, which will cause every call and link using the port to be
torn down.
2000 ABRT Did not receive circuit pack test response within the allowable time period.
1. If this problem persists, reset the circuit pack (busyout board
location, reset board location, and release board
location).
2. If the problem persists, replace the circuit pack.
2012 ABRT Internal system error.
1. Retry the command at 1-minute intervals up to 3 times.
2100 ABRT Could not allocate the necessary system resources to run test.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL Received tones do not match transmitted tones.
1. Retry command at 1-minute intervals up to 3 times.
2. If the problem persists, see TDM-BUS (TDM Bus)
on page 2237 and
TONE-PT (Tone Generator)
on page 2353.
3. If the problem persists, reset the board (busyout board
location, reset board location, and release board
location). Repeat the test.
4. If the problem persists, replace the circuit pack.
PASS Port connections across the TDM bus function properly.
