3-578DS1-BD (DS1 Interface Circuit Pack)

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 CSU’s 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.

1 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 CSU’s 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.
