Abstract

PURPOSE:To decrease a resource for numbering and to make an efficient connection for conversion, by using the kind of end terminals selected by a signalling subscriber and the number of the dialed partner subscriber, and matching the kind of terminals by a switchboard to make possible to communicate between these kinds of terminal ends. CONSTITUTION:A subscriber A informs calling to a switchboard by looping a subscriber line corresponding to a terminal 2a. A switchboard 3 returns dial tone and enters dial receiving condition. And, when the subscriber A dials the number of substcriber corresponding to the partner subscriber B, the switchboard 3 indexes the class 2a of the terminal from the accommodated position of the line of the subscriber and inspects the dead of the accommodated position of the subscriber's line which accommodates the same kind of terminals. In case it is dead, calling signal is transmitted to the appropriated subscriber's line of the subscriber A and line of the subscriber B according to the normal connecting procedures. When the subscriber B responds, a terminal treatment unit 5 responds by looping the line of the subscriber corresponding to a terminal 2a. Then, communicating condition is started.
