Abstract

A process is provided for communicating dual tone multiple frequency (DTMF) tone information over wireless connections between encoders and decoders in a digital cellular telephone system comprising the steps of: receiving in an encoder a DTMF tone; identifying in the encoder the received DTMF tone; designating in the encoder a DTMF-encoding frame that digitally encodes the identified DTMF tone; and transmitting the designated DTMF-encoding frame from the encoder to a decoder by radio over a traffic channel of the digital cellular telephone system.
