DS1-BD (DS1 Interface Circuit Pack)
Issue 1 May 2002
8-615555-233-143
1 FAIL The DS1 interface circuit pack detected a loss of multiframe alarm (LMA). An
out of frame condition occurred on the DS1 interface circuit pack. The DS1
interface circuit pack will transmit a remote multiframe alarm (RMA) to the
remote DS1 endpoint until the LMA is retired.
1. Verify that both endpoints of the DS1 link are administered using the same
signaling mode, framing mode, and line coding. Likewise, verify that any
intermediate CSUs are administered correctly.
2. If the DS1 interface circuit pack connects to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 interface
circuit pack connects directly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
3. Check the physical connectivity of the DS1 pack and of the cable.
4. If this continues to fail, escalate this problem.
PASS No Red alarm is detected on DS1 Interface circuit pack.
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. Use the add ds1 UUCSS
command to administer the DS1 interface if it is not already administered.
2. If 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, 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.
