FAIL The Echo Cancellation test has failed:
● Error 1400 - Echo canceller function failed. The Echo Canceller
Function test, which is executed by firmware, failed.
● Error 1401 - Echo canceller memory failed. The Echo Canceller
Memory test, which is executed by firmware, failed.
Echo Cancellation is no longer being supplied by the board. Clear the
alarm using the following commands: busyout board location,
test board location long, release board location. If the test
still fails, replace the circuit pack.
When this test fails, echo cancellation will be bypassed on every channel
of the board. The circuit pack can still be used for a T1/E1 line interface
without echo cancellation. This capability provides limited service for the
customer until the circuit pack can be changed out.
PASS The Echo Cancellation feature is functioning properly.
0NO
BOARD
The test could not relate the internal ID to the port (no board). This could
be due to incorrect translations, no board is inserted, an incorrect board
is inserted, or an insane board is inserted.
1. Verify that the board’s translations are correct. Execute add ds1
location to administer the UDS1 interface if it is not already
administered.
2. If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, enter
busyout board location.
4. Enter reset board location.
5. Enter release board location.
6. Enter test board location long.
This should re-establish the linkage between the internal ID and the port.
