Description
Outgoing trunk system outage
Definition
The average fraction of equivalent one-way outgoing trunks is unable to
give access to the switch because of an outage in the peripherals on which
the trunks terminate, failures in the facilities carrying the trunks, or failures
of individual trunks.
DMS-100G Switch does not contribute to or provide an equivalent of OM
group TRK, measurement SBU.
Measurement list
The measurement used for OGTRKSOU is the sum of maintenance-busy
usage (TRK SBU) over all outgoing and two-way trunk groups.
System-busy usage for outgoing trunks is given twice the weight of usage
for two-way trunks. This creates a measurement of equivalent one-way
outgoing trunk outage.
Normalizer
OGTRKSOU is normalized per working equivalent one-way outgoing trunk
per unit time. In calculating the number of working equivalent one-way
outgoing trunks, one-way outgoing trunks are given twice the weight of
two-way trunks.
Diagnostics
Verify OM group TRK (SBU). Review trunk maintenance procedures for
monitoring and clearing of trunk troubles. Focused maintenance for lines
and trunks provides an analysis of TRK log messages that may point to
problem trunks. Also check logs TRK106 and TRK109 and check for
carrier (CXR), cable, or PM trouble.
