Setting up the signaling link marginal performance report
Application
The signaling link marginal performance report (SLMPR) is present in offices
that have the CCS7-MTP/SCCP feature (functionality group NTX041AB).
Definition
The SLMPR identifies signaling links in which the following faults occurred
in the last hour:
•
signaling unit errors
•
negative acknowledgements
•
automatic changeovers to alternate signaling links
This report also lists links with faults that exceed the threshold set in table
OFCVAR.
To produce the SLMPR, the system software obtains peg counts from registers
C7SUERR, C7NACKRX, and C7AUTOCO. The peg counts are in
operational measurements (OM) group C7LINK1. The software prints the peg
counts in log report CCS198.
The report indicates if faults exceed one of the thresholds set in table
OFCVAR. If office parameter C7_SLMPR_ALARM_ON of table OFCVAR
is ON, a linkset small alarm raises for the link. The location of the link is the
CCS level of the MAP display.
Note: If the report will include a signaling link, the link must assign option
SLMPR through datafill in table C7LINK, field LINKOPT. Refer to the
Translations Guide for more information.
Example data from the SLMPR appears below. In the example, the numbers
under the SU header are the signaling unit errors. The numbers under NACK
are the negative acknowledgements. The numbers under AUTOCOV are the
changeovers to alternate signaling links. The numbers with an asterisk (*)
exceeded the threshold set in table OFCVAR.
