Adds trunking to a MOTOTRBO™ system.
Trunking is a method of letting individuals efficiently share a resource. I the world of radio communications this means that all users (radios) are normally placed in a rest channel (cue). When a call is placed it is automatically assigned a vacant channel. When ended the radios revert back to the rest channel and the used channel becomes vacant again.
This way the system capacity can be substantially increased compared conventional systems/cues.
