System for interfacing a standard telephone set with a radio transceiver

A telephone interface system for coupling a standard Touch-Tone/rotary dial telephone set with a cellular-type radio transceiver comprising:

• telephone number digital conversion means for converting a group of telephone numbers to digital data and for providing the digital data to the transceiver;
• determination means for automatically determining the last number of the group of telephone numbers;
• send signal means coupled with said determination means for sending a predetermined send code signal to the transceiver in response to the determination means determining the last number;
• call detecting means for detecting an incoming call from the transceiver;
• and
• ring frequency generating means responsive to the incoming call for providing periodic audio ring tone frequency signals to said telephone set.

A cellular-type radio/telephone communication system having at least one remote radio station transmitter-receiver linked with a master cellular-type switching center which is in turn linked with a local telephone central switching office, wherein the remote radio station transmitter-receiver provides a wireless communication link with a base station transceiver, the improvement comprising:

• a standard Touch-Tone/pulse dialing telephone set;
• a cellular-type radio transceiver mounted at a fixed site;
• interfacing means for interfacing said telephone set to said transceiver, said interfacing means including,
• power supply means for supplying DC voltage to said transceiver;
• telephone number digital conversion means for converting touch-tone dialed/pulse-dialed telephone numbers from said telephone set to digital data for temporary storage in said transceiver;
• sending means for enabling said transceiver to transmit the digital data;
• and
• telephone simulation means for providing ring-type and dial tone-type tone frequency signals to the telephone set.

A telephone interface system for coupling a standard Touch Tone/rotary dial telephone set with a radio transceiver used in a telephone communication system wherein the transceiver is capable of radio communication with a telephone network, wherein the interface system comprises:

• telephone number digital conversion means for converting a group of telephone numbers to digital data and for providing the digital data to a transceiver for storage of the digital data therein;
• send signal means for providing a send signal to the transceiver for enabling the transceiver to transmit the digital data stored therein;
• determination means for automatically determining when the send signal is to be provided to the transceiver;
• and
• call detecting means for detecting an incoming call from the transceiver.
