Abstract

PURPOSE:To terminate a cell by an additional number from an ISDN network by discriminating the sort of a calling terminal by a transferring capacity information element and a higher layer matchability information element in a call setting message from the ISDN network, and discriminating whether the termination of the additional number is to be executed or not for every sort of the calling terminal. CONSTITUTION:When a central control unit 38 receives the call setting message from the ISDN 31, it decides the sort of the terminal originated the call by the combination of the transferring capacity information element and the higher layer matchability information element in the message, and checks the set state of a line corresponding to the sort of the terminal, and discriminates whether the additional number is to be terminated or not. When it decides that the additional number is to be terminated, it makes a message sending device 35 send a response message to a line wire, and catches a PP signal receiving analyzing device 33. Next, a dial tone sending device 34 sends a dial tone to the calling terminal of the ISDN 31, and when the calling terminal sends the additional number showing the extension number of an extension terminal 32 by a PB signal in response to it, the PB signal is analyzed by the PB signal receiving analyzing device 53. The central control unit 38 connects the ISPN 31 and the extension terminal 32 by the analyzed extension number.
