Description
Call blockage
Definition
MISCBLK indexes calls not served because of the lack of a software
resource such as an extension block, or the lack of a service circuit or free
operator position.

Measurement list
MISCBLK is based on the sum of TRMTRS treatment counts TRSNOSR,
TRSNOSC, TRSSORD, TRSCQOV, and TRSEMR3 through TRSEMR6,
plus TRMTCM TCMATBS.
Normalizer
The normalizing factor for MISCBLK 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
Many of the indices of the PROVRES hierarchy relate to MISCBLK. If
high levels of MISCBLK persist, review traffic provisioning for the software
or hardware components identified by unfavorable PROVRES utilization or
overflow indices.
Some information may be provided by analysis of LINE138 and TRK138
logs (NOSR, NOSC, SORD CQOV, EMR3 through EMR6, TRMTCM,
TCMATBS) for the treatments covered by MISCBLK, provided logging for
these treatments has been enabled in the various sub-tables of table
TMTCNTL.
