The Wideband Trunk Group Summary report provides data essential for monitoring trunk groups supporting wideband service to assure they provide the expected level of service. The report is modeled after the Trunk Group Summary report but only trunk groups administered to provide wideband service are reported. The report does not display the other trunk groups. If a trunk group is administered to provide wideband service but had no wideband traffic during the measurement period, then zeros are shown on the report.

The yesterday-peak and today-peak reports list the wideband call activity for the peak wideband traffic hour. That is, the measurements shown are those that occurred during the hour in which the Total Usage for wideband service for that trunk group was highest. This is not necessarily the same peak hour as the peak hour for total usage as shown on the overall Trunk Group Summary report. Note that on the Wideband Trunk Group Summary report, the measurements for different trunk groups are not necessarily time-coincident with each other.
