The wideband summary and hourly reports closely parallel the other trunk group summary and hourly reports. That is, visually they contain similar fields, except there is no queuing for wideband calls, so queuing fields are eliminated. Logically, the difference is that only the wideband reports isolate wideband call usage. If the trunk group processes ordinary narrowband calls during the measurement period, the narrowband measurements are not included in the wideband traffic measurements.

With the overall trunk group measurements and the wideband trunk group measurements, you have data for all usage and can calculate the narrowband call usage and counts by subtracting the wideband measurement from the overall measurements.
