Abstract

PURPOSE:To enable the information of the originating subscriber number to the specified subscriber, by carrying out the processing with installation of the called subscriber number detector which stores the specified subscriber number and the means which extracts the originating subscriber number and sends it. CONSTITUTION:The number is stored for specified subscriber Y who desires the service by which the originating subscriber number is informed automatically, and the coincidence secured between the stored number and the called subscriber number is detected. These actions are carried out by called subscriber number detector 25. In addition to this detector, originating subscriber number extractor 28 is provided to extract and then sends the number of originating subscriber X. When detector 25 detects the number of Y, special outgoing trunk 27 is selected via translator 24 and common control unit 23 to call out Y. At the same time, the ringing tone is sent again to subscriber X, and furthermore extractor 28 extracts the number of X. With the answer of Y, the number of X is informed to Y from extractor 28. With the end of this information, the retransmission of the ringing tone is stopped to form the channel between subscribers X and Y.
