Abstract
Abstract A unique cellular telephone (100) connects to a standard telephone set (101) for providing cellular telephone services to subscribers in remote locations not served by a landline telephone system. Cellular telephone (100) includes a cellular telephone transceiver (109), microcomputer (108) and circuitry (102-106) for interfacing the cellular telephone transceiver (109) to the telephone set (101). The interface circuitry (102-107) provides the audio, voltage and dial signal interface to the telephone set (101). The microcomputer (108) controls the interface circuitry (102-106) and is responsive to the telephone set (101) for answering and placing cellular telephone calls. The microcomputer (108) also is responsive to dialing sequences including numerical digits preceded and followed by the # digit for selecting cellular telephone features.
