A digital cellular communication system where fixed subscribers and mobile subscribers can share base transceiver stations, base station controllers and mobile switching centers to communicate with a PSTN. Mobile and fixed subscribers can communicate via any common cellular radio protocol, but the fixed subscribers communicate through conventional telephones using a multisubscriber unit. The system preferably uses a digital speech interpolation pool in a time division multiple access system having different carrier frequencies each of which are time divided into six time slots. The multisubscriber unit communicates with the base transceiver station over a radio link managing most of the tasks required for the air interface so that inexpensive conventional telephones can be used for the fixed subscribers.
