Fault
Threshold
Description
1 2 5 Unexpected message/primitive. Message received but not within specified time
2 1 99 Board/CPU communication error or time out. Message corrupted or not received
3 2 99 Threshold fault counter or Reset counter exceeded
4 3 1 Board controller ROM error
5 3 1 Board controller RAM error
6 3 2 Internal loopback error
72 5
Peripheral state error
- State of peripheral differs from state listed in CPU data base
8130
Base Station not present
- wiring fault or power lost
9 3 2 Peripheral ROM error
10 3 2 Peripheral RAM error
11 2 99 Peripheral status unknown. Two simultaneous faults: status can not be obtained
12/13 2 99 Board status unknown. No communication with board: status can not be obtained
14 2 5 Peripheral communication error or time out. Message corrupted or not received
15 2 2 Board signalling link was cut. When a board is not polled, it resets itself and after
communication has recovered it sends this message to CPU
16 1 10 Board controller poll response error
17 3 99 CPU main processor RAM error
18 3 99 CPU main processor ROM error
19 3 99 CPU EEPROM error
20 2 1 CPU real time clock test failed
21 3 2 CPU–poll processor (8031) RAM error
22 3 2 CPU–poll processor (8031) ROM error
23 1 2 CPU–poll processor communication error
26 2 5 CPU internal buffer overflow
27 2 99 Board controller watchdog reset
28 1 2 HSCX error. Serial communication controller on CPU of signalling highway
29 3 99 Signalling highway down. No communication between CPU and
all
other boards
33 1 1 Initialization procedure not successful. Due to e.g.: no communication with board
34 1 99 Portable Telephone related circuit not present. LTC or DTU–channel
35 2 30 Layer 1 fault at link with PBX: no physical connection or DTU error, L1 = MFG
- this fault may disappear automatically. CPU will set L1 and L2 to AVE again. The
service error message and general alarm remain and must be cleared manually
36 2 30 Layer 1 fault at link with PBX: Error in trunk unit of remote PBX (PBX did detect the
error), L1 = MFG - see note at fault 35
37 1 4 Layer 2 fault at link with PBX: No multiframe synchronization, L1=AVE, L2=MFG
- see note at fault 35
38 1 2 DTU or DLU hardware failure
39 1 99 PC communication error
- when statistics runs, logging is stopped. Statistics must be set "ON" again.
40 3 3 SPU parameters on board have wrong checksum
41 2 99 System Sync Delay hardware out of lock
50 1 * Minimum configuration error, see Chapter 2, Paragrah 2.4.1, "Backplane Reset"
51 2 * Subject is unreliable. Fault is not continuously present
52 2 * Subject could not be tested after maintenance action due to a coincidence
- Subject must be verified if operational. It may be ‘AVE’ but not working. Reset subject
*Not handled by tam_dbas, so threshold is effectively infinite
