“The Channel Verification utility allows you to check the availability of a set of traffic channels, typically those used in one cell or a set of cells. TEMS Investigation lets one or several TEMS mobiles make calls repeatedly on the chosen channels until all timeslots of interest have been tested.
Since there is no way for TEMS Investigation to control the timeslot allocation, traffic channel verification may take a non-trivial amount of time to complete. To reduce the testing time you can use several mobile stations”
You just open channel verification window add as many test cases as trxses you want to check.
