Patent number: 5195129Abstract: A switching system for application services is provided with a terminal. At least one application processor stores a plurality of application programs for providing a plurality of the application services. Switching equipment couples the terminal to the application processor. The terminal has a specifying means for specifying one arbitrary application service out of the plurality of application services. When a user specifies the one arbitrary application service using the specifying means of the terminal, this information is transmitted to a common control unit of the switching equipment. The common control unit receives the application service specifying information from the terminal, and transfers this application specifying information to the application processor. The application processor selects the one arbitrary application service based on the application service specifying information which is transferred from the switching equipment.Type: GrantFiled: November 20, 1990Date of Patent: March 16, 1993Assignee: Fujitsu LimitedInventors: Shigehiko Yazawa, Tsuyoshi Kanai, Hideo Tachieda, Naoto Tada, Norihiro Aritaka, Masatomo Yazaki
