Red Alarm Inquiry Test (#140)
A UDS1 Interface circuit pack raises a Red alarm when the framing pattern of the
incoming DS1 bit stream has been lost. The Red Alarm Inquiry Test checks the
framing status of a UDS1 Interface circuit pack. A UDS1 Interface circuit pack
takes 3 seconds to recognize and report a Red alarm and 10 seconds to
recognize and report the resolution of a Red alarm.
When the UDS1 Interface circuit pack detects a Red alarm, the circuit pack will
transmit a Yellow alarm to the remote DS1 endpoint and send a RED ALARM
message to the maintenance software. After the Red alarm is confirmed, the
1795 FAIL The UDS1 Interface circuit pack detects a Payload Loopback Alarm (PLB).
If the UDS1 Interface circuit pack connects to a leased T1 facility, call the
vendor of the T1 carrier to diagnose the remote DS1 endpoint. If the UDS1
Interface circuit pack connects directly to another DS1 board, call the
system technician of the remote switch to diagnose the DS1 endpoint.
If the UDS1 Interface circuit pack connects directly to a line-side
terminating device such as a PRI terminal adapter contact the vendor of
the terminating device to diagnose the equipment.
PASS Remote DS1 endpoint is in-service. Neither a Blue alarm nor a Line
Loopback alarm nor a Payload Loopback alarm is detected by the UDS1
Interface circuit pack.

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
PCSS 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.
