Overload
32
The converter has detected the onset of an
internal overload condition. This is usually
due either to exceptionally high traffic rates
or failure conditions causing additional
invocation of maintenance procedures.
During overload the converter will continue
to operate as normal. Should the condition
occur on a frequent basis (e.g.: during the
busy hour every day) the condition should be
reported to DataKinetics.
Sync failure
33
None of the PCM ports that have been
configured as possible clock sources
contain a valid PCM signal. Under these
conditions the converter will generate
synchronisation using a local oscillator.
New sync source
34
The converter has selected a new PCM as
the clock synchronisation source.
PCM error ind
35
Diagnostic event relating to the PCM
functionality. Persistent events of this type
should be reported to DataKinetics.
PCM event ind
36
Diagnostic information relating to PCMs.
NUP maint ind
37
Diagnostic event relating to NUP
functionality. Persistent events of this type
should be reported to DataKinetics.
NUP err ind
38
Diagnostic event relating to NUP
functionality. Persistent events of this type
should be reported to DataKinetics.
System restart req
39
The user has changed configuration
parameters that require the system to be
restarted before they can take effect. The
alarm will persist until the system is
restarted.
RDC failure
40
Failure of communication with a remote data
centre. Usually due to incorrect configuration
(IP address, username or password),
connectivity fault or inactive equipment at
the remote end.
All RDC fail
41
Failure of communication with all remote
data centres. Continuous records will be
written to hard disk or discarded as
appropriate. Periodic report data will be
discarded. It is important to note that on
failure of all RDCs any billing records (if
enabled) will be written to local hard disk
which has a limited capacity.
