ABSTRACT:
An RF communications system that can determine when a requesting subscriber unit comprises a TDM capable unit, and when it doesn't. Channel assignments are based upon this determination. The system also includes repeaters that can translate communications in a TDM format as transmitted by a TDM capable unit into non-TDM format for subsequent transmission to a non-TDM capable unit, and vice versa.
