ABSTRACT:
In this invention, a call control information of a subscriber's line is compiled into a packet form, is transferred via a network of a digital switch board to a signal control device, and digital data is also transferred via the network to a handler. Accordingly, a signal from a digital subscriber is efficiently processed, and an analog subscriber is also accommodated so that a call control in the same way as for the digital subscriber is made possible for the analog subscriber.
