DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 1011
FAIL The DS1 interface circuit pack detected a yellow alarm sent by the remote
DS1 endpoint. An out of frame condition occurred at the DS1 endpoint.
1 FAIL The DS1 Interface circuit pack detects a Remote Multiframe Alarm sent by
the remote DS1 endpoint. An out-of-frame condition occurs on the remote
DS1 endpoint.
2 FAIL The DS1 Interface circuit pack is reporting a yellow F5 State alarm. There
is a fault in the user-network interface from the user (PBX) to the network.
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 Yellow alarm nor Remote Multiframe Alarm nor F5 State Alarm is
received from the remote DS1 endpoint.
