Abstract

PURPOSE:To attain redialing while visually confirming one or plural ISDN addresses dialed precedingly by displaying stored ISDN addresses on a display means, designating an address with a designation means and making redialing the address. CONSTITUTION:A signal representing an ISDN address from an analog telephone set 1 is given to a terminal interface 9 and stored in a storage area of a memory 10 sequentially while a management number is given to the signal. When a redial request button 6a is operated, an ISDN address stored in the memory 10 together with its relevant management number is displayed visually on a display means 11 in the ascending order of the management numbers for 2sec each. The operator reads the management number corresponding to the ISDN address and enters an entry key by an input means 6. Thus, the relevant ISDN address is displayed on the display means 11 and sent to an ISDN network 7 as a signal representing a call setting message including the ISDN address.
