DS1 Board Loopback Test (#1209)
This test is destructive.
The DS1 Board Loopback (BLB) Test causes a loopbac k at the TN464F DS1
board edge and tests DS1 board internal circuitr y.
The test is destructive and c an only be initiated by a system technician
demanded
test ds1-loop UUCSS ds1/csu-loop back-tests
command.
All trunks or ports on the UDS1 Interface c ircuit pack must be b usied out via the
system technician busyout board command before running the BLB Test.
When the BLB Test is initiated, maintenance software sends an app ropriate
message to the TN464F UDS1 Interface circuit pac k to start the test. The board
will set up the BLB loopbac k, transmit a test pattern, and verify that the pat tern is
received unaltered through the loop back. If the transmitted and received pattern
is different, the test fails.
When the test is complete, all trunks or por ts on the TN464F UDS1 Interface
circuit pack are restored to the in-service state after the release board co mmand
is entered.
PASS Translation data has been downloaded to the UDS1 Interface circuit pack
successfully.
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. Ensure that the board translations are correct. Execute the add ds1
UUCSS command 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 this is the case, the board is
shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then issue the
busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port.
