Echo Canceller Test (#1420)
This test is destructive.
Note:
Note: This test is executed only for TN464GP/TN2464BP circuit packs that have been
administered on the DS1 circuit pack screen to provide echo cancellation. The
TN464GP/TN2464BP must be busied out before this demand test is run.
This test is for the TN464GP and TN2464BP circuit packs. The test originates from a manually
initiated test board long demand test of a TN464GP/TN2464BP circuit pack. The test
instructs firmware to test the echo cancellation circuity. The TN464GP/TN2464BP firmware
tests echo cancellation on a subset of channels. If any channel fails twice or if any two channels
fail once, the test fails, and echo cancellation is bypassed on every channel of the board.
Otherwise, the test passes, and echo cancellation is configured to the administered parameters.
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.
