— Total calls, number of station-to-station calls, number o f incoming
trunk calls, number of outgoing trunk calls, and number of t andem
calls
These measurements are listed for the last hour, today’s peak hour, and yester-
day’s peak hour.
Large systems offer additional measurements that help con figure the switch,
determine the switch’s capacity for growth, and report unauthorized
switch-access attempts. These measurements include:
■Traffic Summary report, which provides a performance summary of the
switch with the following information:
— Processor occupancy for call processing and system management
— Attendant speed of service
— Total switch-network blocking probability, as well as blocking
probability of the highest port network and highest center-stage link
— Total number of security violations as defined in the securi ty
violations report
— A list of the trunk groups that experienced blocking higher than an
administered design grade of service
— Total trunks that are out of service
— Total number of CDR record buffer high-water-mark violati ons and
buffer overflows
— Time stamps for when the following events last occurr ed:
■Major alarm
■The list of trunk groups to be studied with the detailed report
were last changed
■The list of coverage groups to be studied were last changed
■The list of Automatic Alternate Routing/Automatic Rout e
Selection routing patterns to be studied was last changed
These can be used to verify that your system and its user s are not experiencing
performance degradation due to overloaded switch resources.
■Attendant Position report, which lists the following:
— Attendant usage
— Number of calls answered
— Total time the attendant was available to answer a new call
— Average holding time on calls answered
■Security Violations report, which collects the following measurements:
