The Top Trunk Groups view helps you understand trunk group usage and provides individual trunk usage statistics. Use this page to find underutilized trunk groups and overburdened trunks, where performance can deteriorate.
Statistics for all known trunk groups are included. The most heavily used trunks are shown first.
The name assigned to the trunk group. Click to drill down into an hourly breakdown of usage for this trunk group. The trunk group name is based on information from the monitored call traffic and the naming convention employed by the trunking equipment.
The average usage during the time period, expressed as a percentage of capacity. Average usage is based on capacity, divided by the timeframe.
To identify underused trunk groups, sort this column to see the least used trunk group first.
The highest recorded usage during the selected time period, expressed as a percentage of capacity. Maximum usage is a good indicator of potential capacity issues. Even when the average usage is low, the maximum usage is significant because it often indicates the usage during the “busy hour” of the day. Maximum usage is based on capacity, multiplied by the timeframe.
(Cisco only) An estimation of the probability that a VoIP call will receive a busy signal. The GoS value (a decimal fraction) is always expressed with reference to the busy hour when the traffic intensity is the greatest. GoS is reported from the perspective of the origination Location or gateway device (the outgoing direction).
The number of call minutes used to calculate usage statistics. This value provides a sense of the scope of activity and helps determine the significance of the data, based on sample size.
The number of call minutes that were supported during the selected time period. The capacity is discovered during monitoring or is manually supplied during configuration.
