Chapter 8 Alarm Fault Code Listing

Critical

(CRT)

63 PSU failure

The system has detected that one or more

power supplies have failed. The system is able

to operate with the loss of a single power

supply but the power supply must be replaced

at the earliest possible opportunity.

SYS PSU ID 3 0

Critical

(CRT)

72 Fan failure

The system has detected a failure of one or

more or its cooling fans leading to an

inadequate cooling supply. The faulty fan(s)

should be replaced immediately.

SYS 0 3 0

Critical

(CRT)

76 CPU warning

The system has detected that one or more of

the CPUs is likely to fail.

SYS 3

Critical

(CRT)

77 CPU failure

The system has detected that one or more of

the CPUs has failed.

SYS 3

Critical

(CRT)

78 Memory failure

The system has detected that one or more of

its memory modules has failed.

SYS 3

Major

(MJR)

1 PCM loss Loss of signal at PCM input port PCM PCM 4 0

Major

(MJR)

2AIS

PCM input port contains the Alarm Indication

Signal (all ones on all timeslots)

PCM PCM 40

Major

(MJR)

Frame sync

loss

Loss of frame alignment on PCM port PCM PCM 4 0

Major

(MJR)

4Frame slip

A frame slip occurred on the PCM port. This

alarm event is given for each occurrence of a

frame slip.

PCM PCM 40

Major

(MJR)

5 Remote alarm

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.

PCM PCM 4 0

Major

(MJR)

6 BER > 1:10^5

The input PCM signal contains a Bit Error Rate

(BER) 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

board at the remote end.

PCM PCM 40

Major

(MJR)

7 BER > 1:10^3

The input PCM signal contains a Bit Error Rate

(BER) in excess of 1 in 1000 as measured on

the frame alignment pattern. This is usually

due to faulty cabling or a faulty PCM board at

the remote end.

PCM PCM 4 0

Major

(MJR)

9 C7 link fail

An SS7 signaling link has failed. Usually due

to incorrect configuration (signaling timeslot),

connectivity fault or inactive signaling

terminal at the remote end.

SIG C7LINK 40

Major

(MJR)

15 Fan warning

The system has detected either the failure of

one of the cooling fans or that a fan is likely to

fail. The cooling will remain adequate during

this condition but the fan should be replaced

at the next convenient opportunity.

SYS 0 4 0

Major

(MJR))

17 Alarm Test 2

This event indicates that the user has invoked

the alarm test for alarm class 2 using the

ALTEI command.

SYS 0 4 0

Major

(MJR)

20 Temperature

The internal temperature is outside a preset

threshold indicating either an internal fault or

failure of the cooling arrangements.

Inspection should take place immediately.

SYS CPU ID 4 0

Major

(MJR)

33 Sync failure

None of the PCM ports that have been

configured as possible clock sources contain a

valid PCM signal. Under these conditions the

Signaling Gateway will generate

synchronisation using a local oscillator.

PCM 040

DIAG

† 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.
