Abstract
Abstract A telephone set incorporates a conventional keypad to allow the user to program a custom ring tone and pattern into the telephone set. After such programming is established, when the telephone set detects a ring signal from the central switching station, a ringer is activated and deactivated according to the programmed ringing parameters so as to provide a truly customized ring signal to the user.
