'Summary period' ISUP Circuit Group Statistics

There are eight 'Summary period' ISUP Circuit Group Statistics objects, which each display statistics collected over a different time interval. Note that the summary periods are preconfigured; you cannot change the summary periods or create new 'Summary period' ISUP Circuit Group Statistics objects. All the 'Summary period' ISUP Circuit Group Statistics objects have the same fields. All the fields are read only and there are no management actions associated with these objects. However, you can reset all the fields of the 'Summary period' ISUP Circuit Group Statistics objects by clicking on the 'Reset statistics' pushbutton displayed in the ISUP Circuit Group object.


Parameter

Type of statistic

Description
Count of state failures Counter Number of state failures of this circuit group during the summary period. This counts the number of times the Actual status of the ISUP Circuit Group has moved out of the Active state when not requested.
Cumulative downtime Counter Cumulative downtime of this circuit group during the summary period. This counts the number of milliseconds for which the circuit group has not been active.
Number of circuits configured Gauge Number of circuits currently configured in this circuit group. This counts the total number of circuits configured irrespective of their current status.
Number of circuits available Gauge Number of circuits currently available for use in this circuit group. This counts the total number of circuits that are available for use by incoming and outgoing calls, including those that are currently in use. This count excludes inactive and blocked circuits.
Number of circuits in use Gauge Number of circuits currently in use in this circuit group. This counts the total number of circuits that are being used for call traffic, or are in use by pending-active or pending-inactive calls, or are being tested.
Count of incoming call attempts Counter Number of incoming call attempts during this summary period. This counts the total number of ISUP IAM and CRM requests received for circuits in this circuit group.
Count of outgoing call attempts Counter Number of outgoing call attempts during this summary period. This counts the total number of times the local ISUP signaling stack has initiated an outgoing ISUP IAM or CRM request for a circuit in this circuit group.
