analog phone

The original telephone technology, which converts air vibrations into an analogous electrical frequency. Unless a key telephone system, digital PBX or voice over IP (VoIP) is used, most homes and small offices still use analog phones, and the local loop is mostly analog. Likewise, the first cellular phone systems were analog and are still widely used as a backup system. All new cellular systems that are deployed are digital. See local loop, AMPS, TDMA, CDMA and cellular generations.
