Red Alarm Inquiry Test (#140)
DS1 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 DS1 Interface circuit pack. DS1 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 DS1 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
maintenance software places all trunks of the circuit pack into the out-of-service
state. The inquiry test will be run every 10 minutes until the Red alarm is cleared.
1795 FAIL The DS1 Interface circuit pack detects a Payload Loopback Alarm (PLB). If the
DS1 Interface circuit pack connects to a leased T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 Interface circuit
pack connects directly to another DS1 board, call the system technician of the
remote switch to diagnose the DS1 endpoint.
PASS Remote DS1 endpoint is in-service. Neither a Blue alarm nor a Line Loopback
alarm nor a Payload Loopback alarm is detected in the DS1 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. Check to ensure that the board translations are correct. Use the add ds1
PCSS 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 if 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, 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 link between the internal ID and the port.
