Abstract: A communication system offering specific services to specific persons bears a portable memory device with a record of personal information such as the bearer's identification number, class of service, personal data, etc. In making a call, the bearer of the memory device puts it on a communication terminal device and the terminal device reads out the personal information, which is transferred to a data processor such as a central processor in the exchange so that a service specific to the calling person is rendered.

Abstract: In a communication system, the user can be instructed by a speech message to execute an operation according to the procedure for each of various different services. The switching system within the communication system identifies the kind of service which the user wants and then supplies speech information in a conversational mode to the communication terminal device, thereby instructing the user to execute an operation procedure for the service on the communication terminal device. Therefore, the user can enjoy a desired service even if he has no preliminary knowledge of the operation procedure for the service.

Abstract: A communication system renders improved service for users by announcing in a vocal message information about the call such as the called person's name, calling person's name and class of urgency of the call during the phase or ring. For paging the called person's name, a directory number assigned to each of telephone users is dialled, or for notifying the calling person's name, a memory card such as a magnetic card memorizing the identification code of a calling person is set on a calling terminal device, so that necessary information is transferred to the switching system. The information is edited and synthesized into a vocal message in the switching system or in each terminal device using the speech synthesizing technique, and it is announced on the called terminal device during the silent time of the phase of ring.

Abstract: A personal-call communication system wherein a personal identification number is assigned to each telephone user, and an arbitrary person is called by wireless by dialing a corresponding personal calling number. The called person sets an ID-card-type portable device memorizing one's own personal identification information in a card reader of a telephone set, and communicates with the calling party over the wire system via an exchange. The system allows a direct call of an individual person, who in turn has a choice as to whether or not a response should be taken depending on the calling party whose name is indicated to the called party.

Abstract: A multi-stage connection switch frame comprising crossbar switch lattices arrayed in at least three stages which are interconnected through links. Two adjacent stages of the multi-stage connection switch frame comprise a plurality of vertical groups each group comprising a plurality of upper part of verticals connected to each other by horizontals thereof in a multi-stage configuration and a plurality of lower part of corresponding verticals in all of the vertical groups being connected to each other by horizontals thereof in a multi-stage configuration, thereby to form the lattices in two stages which are coupled to each other through the verticals.
