Description
Miscellaneous failures
Definition
The proportion of calls lost during call setup because of machine-caused
failures.
DMS-100G Switch does not contribute to or provide an equivalent of
• OM group CP, measurement WINITC
• OM group OFZ, measurements NIN, NIN2, INABNM, and INABNC
Measurement list
MISCFL is based on the sum of CP CPTRAP, CPSUIC, and WINITC.
Normalizer
The normalizing factor for MISCFL is total call attempts minus the sum of
abandoned calls OFZ INABNM, INABNC, and ORIGABN, minus failures
before dial tone OFZ ORIGLKT. In international offices, the subtracted
quantities are replaced by OTS INCABNM, INCABNC, SYSABDN,
ORGABDN, and ORGLKT minus TRMTCU TCUORSS.
Diagnostics
Ensure that Nortel Field Technical Support is notified promptly when traps
and call suicides occur. Save copies of log messages associated with
restarts, traps and call suicides, plus log messages for the periods before and
after these events. Pay particular attention to SWERR, TRAP, AUDT101,
AUDT103, AUDT197, CC103, CC104, NET101 (with LINE104 OR
TRK113), AUDT100, AUD395, AUD398, CC107, INIT, SOS100, and
SWCT103.
