CSU Equipment Loopback Test (#1210)
This test is destructive.
The CSU Equipment Loopback (ELB) Test causes a loopback at the near-edge of
the local Lucent 120A1 CSU Module or the 401A T1 Sync Splitter and tests the
connection from the TN464F DS1 board to the CSU Module/T1 Sync Splitter (DS1
board edge interconnecting cable, and CSU Module/T1 Sync Splitter edge). This
test will only be performed if the Lucent 120A1 CSU Module or the 401A T1 Sync
Splitter is present, administered, and connected to a 1.544 Mbps TN464F DS1
circuit pack on the back of the port carrier.
The test is destructive and can only be initiated by a system technician
demanded
test ds1-loop UUCSS ds1/csu-loopback-tests
command.
All trunks or ports on the UDS1 Interface circuit pack must be busied out via the
system technician
busyout board
command before running the ELB Test.
When the ELB Test is initiated, maintenance software sends an appropriate
message to the TN464F UDS1 Interface circuit pack to start the test. The board
will set up the ELB loopback, transmit a test pattern, and verify that the pattern is
PASS The BLB test executed successfully. The test pattern was transmitted and
received successfully up to the TN464F DS1 board edge.
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.
