11.8.4 Soft Error Buffer (SEB)
If the OMCU operating system detects a 'soft error' this buffer will store relevant data
on the error type. Any entries in this array should be conveyed to Traffic Engineering
(Siemens Poole) for detailed analysis.
FORMAT: SEB <n>
where <n> is the minor index (0 - 3) and enables access to the last four soft errors (0
is the most recent). The data is presented in HEX
The codes that most likely to be encountered are:
ERROR=0001
RAM read/write test fail
ERROR=0403
PROM checksum fail
ERROR=120?
Processor errors
(bus errors, illegal instructions, unknown interrupts etc)
ERROR=138?
Bus / MOVA I/O Board UART errors
(RS485 communications chip operation fault)
ERROR=161?
MOVA REQUESTED REBOOT – SEE MOVA ERROR
LOG FOR REASON.
11.8.5 Radio Clock Signal (RCS)
RCS example display format:
RCS: LAST 26MAY98 07:44:00 MIS:0 RFQ:95 LNK:0 00XXX00 00:00:00 DEC 19
Time of last synchronisation to the radio clock
Input signal to OMU missing
(count in minutes)
RF quality poor (count in minutes)
Corruptions on link from OMU to radio clock
(count in minutes)
Time currently being received from the radio clock
Seconds count - incremented as the time signal is
decoded over a 1-minute period
Status: DEC = Decoding, IDL = Idle
With a correctly operating radio clock, the time of last synchronisation will be within
one or two minutes of the current time, and the MIS, RFQ and LNK error counts will
be zero.
