Abstract: In an ISDN line circuit channel monitor system having a digital line circuit controller, a line circuit network and a call processor accommodating network, there are provided monitor equipment and a connection making part. The monitor equipment is coupled to the digital line circuit controller, the first network or the second network, and monitors D and B channels of a basic interface and a primary rate interface. The connection making part connects to the monitor equipment time slots related to a monitored channel of a terminal in conformity with either the basic interface or the primary rate interface.

Abstract: An apparatus for verifying service user's information consists of a switch system for setting a call between one terminal and the other terminal and a data memory connected to this switch system. This data memory stores information indicating the number of a service user on which a charge previously applied by a subscriber is imposed and information on a validity of this service user's information. The switch system includes a checking section. The checking section checks at first effects, when the subscriber requests setting of a call to be charged for a talk on the basis of the above-mentioned information from one terminal, a formal check of the service user's information sent with the request by the subscriber. If this formal check is passed, the checking section requests the data memory for a collation as to whether or not the service user's information is valid.

Abstract: A service switching point equipped with a switching function and connected via a communication network to a service control point equipped with an additional-service control function sends a request for an additional service to the service control point when the additional service is requested by a terminal (subscriber). The service control point executes control for the additional service, creates additional service charging information (first charging information) related to the additional service and sends the first information to the service switching point. The latter creates second charging information, which is information related to the ordinary service, as part of detailed charging information and creates detailed charging information by combining the first charging information, which is sent from the service control point, with the second charging information.

Abstract: In control system for communication between units, each unit stores an adjacent-unit identifying number fixedly corresponding to each unit adjacent to one of the units, and forms a relative address, the relative address of the originating unit being "nil" and the relative address of the destination unit being expressed by a set of adjacent-unit identifying numbers of all units provided on the communication path between the originating unit and the destination unit, excluding the originating unit and including the destination unit, the signal message routing being executed in such a way that, when the received destination address is "nil", the unit receiving the message is determined to be the destination unit, and when the received destination address is not "nil", the unit receiving the message transfers the message to the next-stage unit, whereby a simple addressing process is realized.
