- Check the connections of the SCB1(2).
- Check P704.03"SCom/SCB Tlg OFF"
- Replce SCB1(2)
- Replace CU (-A10)

1: Board code incorrect
2: TB/CB board not compatible
3: CB board not compatible
5: Error in configuration data
6: Initialization timeout
7: TB/CB board double
10: Channel error
Check the T300/CB board for correct
contacting, check the PSU power supply,
check the CU / CB / T boards and check the
CB initialization parameters:
- P918.01 CB Bus Address,
- P711.01 to P721.01 CB parameters 1 to 11

1: SCB heartbeat-counter
2: Additional CB heartbeat-counter
- Acknowledge the fault (whereby automatic
reset is carried out)
- If the fault re-occurs, replace the board
concerned (see fault value)
- Replace ADB
- Check the connection between the subrack
and the optional boards (LBA) and replace, if
necessary
Fault value r949:
1 = TB/CB
2 = additional CB
- Check the connection to TB/CB
- Check P722 (CB/TB TlgOFF)
- Replace CB or TB
