ABSTRACT:
A programmable interface system for interfacing a standard telephone set with a radio transceiver as part of a telephone network is provided. The radio transceiver may be a conventional cellular-type transceiver or other transceiver having typical control inputs and outputs similar to that provided by cellular transceivers. The programmable interface system converts tone-dial or pulse-dial inputs from the telephone into a serial data stream for storage in the transceiver. The programmable interface system can be programmed to automatically determine when the last numeral or digit is dialed for a particular area telephone system and provides a send signal to the transceiver when such determination is made. The system responds to incoming call signals, such as alert signals, from the transceiver and rings the telephone accordingly. The system simulates ring and dial-tone type signals under conditions typical of standard telephone set usage.
