(LED)
			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
Critical	32	Overload	maintenance procedures. During	SYS	0	3	0
(CRT)			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.
			Failure of communication with all
Critical			remote data centres. Continuous
	41	All RDC fail	records are written to hard disk or	SYS	0	3	0
(CRT)
			discarded as appropriate. Periodic
			report data is discarded.
			Interaction with the hard disk is no
Critical			longer possible. No further use of				Diagnostic
	46	Hard disk fail	the hard disk is attempted until the	SYS	0	3
(CRT)			system is restarted. The most likely				code
			cause is a physical failure of the
			hard disk drive.
			The system has detected that one
			or more power supplies have failed.
Critical			The system is able to operate with
	63	PSU failure	the loss of a single power supply	SYS	PSU ID	3	0
(CRT)
			but the power supply must be
			replaced at the earliest possible
			opportunity.
			The system has detected a failure
Critical			of one or more or its cooling fans
	72	Fan failure	leading to an inadequate cooling	SYS	0	3	0
(CRT)
			supply. The faulty fan(s) should be
			replaced immediately.
Critical	76	CPU warning	The system has detected that one	SYS		3
(CRT)			or more of the CPUs is likely to fail.
Critical	77	CPU failure	The system has detected that one	SYS		3
(CRT)			or more of the CPUs has failed.
Critical			The system has detected that one
	78	Memory failure	or more of its memory modules has	SYS		3
(CRT)
			failed.

Major			A frame slip occurred on the PCM

			PCM port is receiving a Remote

Major	5	Remote alarm	indicates that the remote end is	PCM	PCM	2	0
			either failing to achieve frame
(MJR)
			alignment or that it is experiencing

			signal.

†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.
