FAIL

The DS1 Interface circuit pack detects a Red alarm. An out-of-frame 
condition occurs on the DS1 Interface circuit pack. DS1 Interface circuit 
pack will transmit a Yellow alarm to the remote DS1 endpoint until the Red 
alarm 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.

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.
