Abstract

PURPOSE:To eliminate the need for a speaker and to reduce the cost by sending a call to an installed room of a home telephone adaptor when a call comes from a doorphone during external line and extension talking or facsimile communication. CONSTITUTION:When a call comes from a doorphone 2 while a general telephone set makes talking to an external line and an extension, a home telephone master set 1 sends the call to an adaptor 5. A CPU of the adaptor 5 activates a FAX terminal call tone connection relay to ring a call tone of a FAX 7 from a call tone generating circuit thereby informing a call from the doorphone 2 to a talker of the general telephone set. On the other hand, when a call comes from the doorphone 2 during FAX communication, the CPU of the adaptor 5 activates the FAX terminal call tone connection relay to ring a call tone of the general telephone set. Thus, when the call of the doorphone comes during telephone set talking or FAX communication, the call is sent to an installed room of the adaptor, the installation of the speaker or the like is not required and the cost is reduced.
