Abstract

PURPOSE:To perform switching between both analog and digital systems economically by making an original connection by starting with subscribers equipped to an analog network and by switching a connection with a digital network at need after a number is received. CONSTITUTION:A digital switch network 29 is added to analog switch networks 22-24; and analog circuits are equipped to the analog switch networks, and a digital circuit to the digital switch network separately and respectively. A subscriber interface function is provided to the analog switch network. Subscribers are equipped to the analog switch networks and an origination connection from subscribers and the reception of a selective signal are performed through the analog switch networks. For an outgoing connection made via a digital transmission line, a calling subscriber is switched to the digital switch network via an analog line-concentrated network after the reception of a selective signal and connected to the digital circuit. An incoming call is received via an analog trunk link switch 23 or digital trunk link switch 29 and the analog line-concentrated network 22 according to an incoming analog or digital trunk.
