Multifunction telephone system

Abstract

Abstract PURPOSE: To use the same key button in the visit destination as well as at home to control an intra-telephone device of an automatic answering telephone set, etc., by sharing dial keys for telephone dialing instead of a private operation button. CONSTITUTION: When a subscriber will manually operate the automatic answering telephone set at home, he depresses a prescribed key out of dial keys 21 after transmission of a password number. By this key depression, the output from a DTM oscillating circuit 22 is supplied to a tone decoder 25 through an amplifying circuit 24. A CPU to which the output of the decoder 25 is given controls running of a reception tape and a response tape and reCording and reproducing heads RPH-1 and RPH-2 to perform recording and reproducing. When he will remotely control the automatic answering telephone set in the visit destination, he uses a push-phone in this destination to call this telephone set. Following operations are performed in the same manner as manual operation at home. COPYRIGHT: (C)1989,JPO&Japio
