9. ANNEX A: Alarm Fault Code Listing

Note: The meaning of individual event codes (in particular the coding of the DIAG field) may be
changed in subsequent releases of the converter software without prior notification.
CODE
PCM loss
1
Loss of signal at PCM input port.
AIS
2
PCM input port contains the Alarm Indication
Signal (All ones on all timeslots).
Frame sync loss
3
Loss of frame alignment on PCM port.
Frame slip
4
A frame slip occurred on the PCM port. This
alarm event is given for each occurrence of
a frame slip.
Remote alarm
5
PCM port is receiving a Remote Alarm
Indication. This usually indicates that the
remote end is either failing to achieve frame
alignment or that it is experiencing a high bit
error rate on the received signal.
BER > 1:10^5
6
The input PCM signal contains a Bit Error
Rate in excess of 1 in 100,000 as measured
on the frame alignment pattern. This is
usually due to faulty cabling or a faulty PCM
card at the remote end.
BER > 1:10^3
7
The input PCM signal contains a Bit Error
Rate in excess of 1 in 1000 as measured on
the frame alignment pattern. This is usually
due to faulty cabling or a faulty PCM card at
the remote end.
Reserved
8
C7 link fail
9
An SS7 signalling link has failed. Usually
due to incorrect configuration (signalling
timeslot), connectivity fault or inactive
signalling terminal at the remote end.
Reserved
10
Link set fail
11
All signalling links in an SS7 signalling
linkset have failed. Usually due to incorrect
configuration (point codes or signalling
timeslots), connectivity fault or inactive
signalling terminal at the remote end.
