Critical

32 Overload
The Signaling Gateway 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 Signaling Gateway will
continue to operate as normal.
Should the condition occur on a
frequent basis (for example, during
the busy hour every day) the
condition should be reported to
your support representative.

41 All RDC fail
Failure of communication with all
remote data centres. Continuous
records are written to hard disk or
discarded as appropriate. Periodic
report data is discarded.

Critical
(CRT)
46 Hard disk fail
Interaction with the hard disk is no
longer possible. No further use of
the hard disk is attempted until the
system is restarted. The most likely
cause is a physical failure of the
hard disk drive.

† The “Class” column provides the initial default setting of the alarm class for each fault code. The alarm class for any particular
alarm code is configurable using the ALCLS command and can be viewed using the ALCLP command. Changing the alarm class for
an event type changes the Severity indicated by the LEDs and/or relays.
