Abstract: In a fixed cellular telephone system, the taking of a standard wireline telephone set off-hook triggers the establishment of a voice/traffic channel connection between a connected fixed cellular terminal and the cellular system switch. Digits of the telephone number of the party to which the call is directed are entered through the telephone set. These digits are then transmitted by the fixed cellular terminal to the serving cellular network switch as out of band data messages transported over a control channel supported by the established voice/traffic channel connection. The data message digits are then converted to dual tone multi-frequency (DTMF) tones, with the tones processed in a conventional manner to complete the call connection to the called party.
