Abstract

PURPOSE:To connect a call quickly and to improve transmission quality, by providing a facsimile packet switchboard between a packet switching network and a telephone switching network. CONSTITUTION:Between a telephone switching network 1, and a packet switching network 11, a facsimile packet switchboard 21 having a function for relaying a signal on both the switching networks is provided. For instance, in case when a message is sent to a facsimile subscriber's terminal 13 of the network 11 from a facsimile subscriber's terminal 3 of the network 1, the terminal 3 calls the device 21, transfers a discrimination code and a meassage of the terminal 13, afterwards, makes the device 21 transfer the message to the terminal 13. Also, in the switching network 1, discrimination codes of the terminal 3 and 13, and other information required for communication are transferred in conformity with an advice of the International Telegraph and Telephone Consultative Committee.
