Communication apparatus utilizing a telephone line

Abstract

Abstract Some communication apparatuses (1) which utilize telephone line have a function called the repertory dialing. The repertory dialing is to store, in a memory (9) provided in the telephone set or the like, pairs of destination telephone numbers and numbers corresponding thereto, of two digits for example, called compressed dial numbers, thereby to perform telephone calling operation by entering one compressed dial number corresponding to a desired destination telephone number. According to the invention, the communication apparatus (1) performs setting and canceling of the compressed dial number mode by detecting the state, on hook or off-hook, of the handset (3) by means of a hook state detecting means (5). When the handset (3) is in on-hook state, compressed dial number mode is selected. By operating the dial number keys (13) to enter a compressed dial number in this state, corresponding destination telephone number is read out of the memory (9) and calling operation is performed. Thus telephone number entering operation is simplified to enable accurate and quick input operation.
