Red Alarm Inquiry Test (#140)
Red Alarm Inquiry Test (#140)
A DS1/UDS1 Interface circuit pack or DS1 Interface Media Module 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 board.
When the DS1 board detects a Red Alarm, it transmits a Yellow Alarm to the remote DS1
endpoint and sends a Red Alarm message to the system. After the Red Alarm is confirmed, the
system places every trunk or port of the DS1 board into the out-of-service state. The inquiry test
runs every 10 minutes until the Red Alarm is cleared.
When the Red Alarm is cleared, the DS1 board stops transmitting the Yellow alarm to the
remote DS1 endpoint. The system restores all trunks or ports of the DS1 board to the service
state they were in before the Red Alarm occurred.
This test is run on the following maintenance objects:
● DS1-BD (DS1 Interface Circuit Pack)
● MAPD-BD (MAPD Interface Circuit Pack)
● MG-DS1 (DS1 Interface Media Module)
● UDS1-BD (UDS1 Interface Circuit Pack)
Loss of Multiframe Alarm
If the DS1 circuit pack or media module is administered using DMI-BOS signaling, it raises a
LMA (Loss of Multiframe Alarm) when it cot interpret the incoming signaling bits to synchronize
to the multiframe pattern received in the 24 th chel. Once the DS1 board detects an LMA, the
circuit pack transmits a RMA (Remote Multiframe Alarm) to the remote DS1 endpoint.
