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 p ack 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 connec ts to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 interface
circuit pack connects d irectly to a switch, call the system technician of the
remote switch to diag nose the DS1 endpoint.
3. Check the physical connectivity of the DS1 pack and of the c able.
4. Replace the loc al DS1 interface circ uit pack, and repeat the test.
1 FAIL The DS1 interface circuit pack detected a loss of multiframe alarm (LMA). An
out of frame condition oc curred on the DS1 interfac e circuit p ack. 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 connec ts to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 interface
circuit pack connects d irectly to a switch, call the system technician of the
remote switch to diag nose the DS1 endpoint.
3. Check the physical connectivity of the DS1 pack and of the c able.
4. Replace the loc al DS1 interface circ uit pack, and repeat the test.
PASS No Red alarm is detected on DS1 Interface circui t pack.
