Abstract
PURPOSE:To ensure a transmission of a wide-band data without completing or discontinuing a call, by providing crosspoint switch circuits exclusively used for voice signal band and for wide-band data signal, into a switchboard. CONSTITUTION:A crosspoint switch circuit 322 exclusive for voice signal band and a crosspoint switch circuit 321 exclusively used for wide-band data signal are provided into a switchboard. A dial signal shifted to the wide-band data signal band is transmitted from a terminal device that transmits a wide-band data, and an exchange connection is carried out to an information receiving part by means of the circuit 321. In such way, both the calling and transmission of data are carried out independently through a circuit. Thus the signal necessary for an exchange control of a data terminal device is transmitted after shifting to the wide-band data signal band such as the basic group band or the like to avoid a mixture of a voice and a wide-band data. Furthermore an individual control and an independent exchange control are possible between the voice and the wide-band data which are transmitted through one circuit.
