MX-ONE SYSTEM DESCRIPTION
92 21/1551-ASP 113 01 Uen N2 2014-01-28
– Signal entry in addressed program unit exists for the sent
signal
– Address control value correct
If any fault is found, the signal is not executed and the job is
discarded. The signal that caused any of the above errors is stored
for manual fault investigation.
Server/Gateway Disturbance Counter
Each LIM has a disturbance counter that reflects the quality of the
program execution in the LIM. The counter is incremented a number of
steps each time a fault occurs. The number of steps depends on the
severity of the disturbance.
An alarm is sent when the first execution fault after start or restart occurs
and when the counter exceeds the maximal allowed value. The counter
is periodically decremented to avoid exceeding the value.
6.4.8 Alarm Handling
Alarm handling is handled by the service system. For more information
about the alarm handling function, see 9.2 Fault Management.
6.4.9 Automatic Fault Administration
Automatic fault administration is handled by the service system. For
more information about the automatic fault administration function, see
9.2.1.1 MX-ONE Telephony System.
6.4.10 Signal Tracing
The signal tracing function implements both the trace error log and the
general trace function. The function implies that signals or text items are
copied and preserved as the program execution is handling an activity
so that the function can be analyzed later on.
The first trace individual is used by the error log function and is therefore
always enabled in all servers.
Up to fifteen signal traces can be specified simultaneously.
The following four types of signal traces exist:
•Error log
Error log is always enabled and stores information about error situ-
ations in the software.
• Sequential tracing
