摘要： PROBLEM TO BE SOLVED: To provide an exchange system in which an ISDN line can be normally connected even when a terminal in which the subscriber's number of an ISDN network being the destination of calling is not set as a direct dial-in number calls the ISDN network. SOLUTION: When a terminal 4 calls an ISDN network B of plural ISDN networks (A, B), a control circuit 12 compares the subscriber's number of a trunk line 16 set at the ISDN network B with the dial-in number of the calling terminal 4. When they are made coincident, the dial-in number is transmitted, and when they are not made coincident, a central number preset at the ISDN line, that is, the subscriber's number is transmitted to the ISDN network B as caller's number information.

摘要： PROBLEM TO BE SOLVED: To provide a telephone exchange capable of relieving a processing load, reducing an operating cost, and quickly and properly carrying out call termination processing. SOLUTION: When an incoming call transmitted via a control channel of an IP network IPN arrives in a master unit 1A, an IP network interface section 12-1 receiving the incoming call discriminates whether or not there is a free voice circuit among a plurality of voice circuits, and transfers the incoming call to a next IP network interface section 12-2 not through a call control section 11 when all the voice circuits are busy. IP network interface sections 12-2 to 12-n sequentially carry out incoming call transfer processing until a free voice circuit is found out when receiving the incoming call.

摘要： PROBLEM TO BE SOLVED: To provide an exchange system which avoids the selection of an infinite loop by a simple constitution.
SOLUTION: For originating a call from an originating terminal a to a terminating terminal e, nodes A, B and C are connected in this order. If the originating to a node E fails at the node C because of a circuit failure, etc., an originating trunk loop to the node B is selected. But, using a table showing the relation of originating trunk loops for avoiding an infinite loop to terminating trunk loops, route selection is decided to be impossible and stopped, the node B is informed of this decision. An alternate route is selected again at the node B and connected to nodes D, E, thus avoiding the selection of an infinite loop.

摘要： PURPOSE:To accurately carry out a long-term stabilization test without manual operation in short time by performing the charging totalization processing based on the pseudo call information and notifying each end of the totalization processing to a test device. CONSTITUTION:When a long-term stabilization test is required to a communication tariff managing device B1, a test device D is connected to the managing device B1 instead of a private branch exchange. Then the device D starts the test. That is, the device D supplies the time change instruction information and the pseudo call information to the managing device B1. Thus the time of the managing device B1 is advanced by a fixed degree and changed to the time when the charging totalization is carried out. A charging totalization processing test is carried out based on the pseudo call information. When this test is over, the end information is sent to the device D from the managing device B1. Thus the device D supplies the next time change instruction information and pseudo call information to the managing device B1.

摘要： PROBLEM TO BE SOLVED: To provide a system in which exchange devices are connected through digital private lines, and coherent service regulation is performed for the whole system. SOLUTION: Exchange devices 1-5 are respectively provided with a service group identifier table, a network group identifier exchange table, and a service contents deciding table. In response to a service request using a digital private line from extension terminals T11-T1i, T21-T2j, T31, T41-T4k, and T51-T5m, or a public network NW, a service group identifier for a network assigned to the origin of the service request is inserted into an extended information area in a call setting signal, and transmitted through the digital private line to the exchange device at the other party. Then, the exchange device at the other party executes control, related with the service corresponding to the request based on the stored contents of the respective network group identifier exchange table and service contents deciding table.
