PURPOSE:To simplify the detection and change of a subscriber's number by providing a calling-subscriber's number detector composed of a memory unit and a program processor. CONSTITUTION:From common controller MKR to subscriber's number detector ANI/AMR, equipment-position information on the line link frame of main link ML of calling subscriber SUBA and that on outgoing sender link OSL of outgoing sender OS are both supplied. As a result, central processing unit CPU is driven and random access memory RAM is also driven. Then, a read from random access memory RAM is done; and then, the equipment-position information on the line link frame is converted into a subscriber's number of subscriber A, and the equipment-position information on outgoing sender link OSL of outgoing sender OS is into an outgoing sender OS number. |
