out-of-service state. The inquiry test will be run every 10 minutes until the Red
alarm is cleared.
When the Red alarm is cleared, the UDS1 Interface circuit pack will stop
transmitting the Yellow alarm to the remote DS1 endpoint. The maintenance
software restores all trunks or ports of the UDS1 Interface circuit pack to the
service state before the Red alarm occurs.
Loss of Multiframe Alarm
If the UDS1 Interface circuit pack is administered using DMI-BOS signaling, the
UDS1 Interface circuit pack raises a Loss of Multiframe Alarm (LMA) when it
cannot interpret the incoming signaling bits to synchronize to the multiframe
pattern received in the 24th channel. Once the UDS1 Interface circuit pack
detects an LMA, the circuit pack will transmit a Remote Multiframe Alarm (RMA)
to the remote DS1 endpoint. Maintenance software handles both Red alarm and
LMA alarm(s) using the same mechanism.
