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.
