特徴とする情報伝送システム。 In an information transmission system in which an information communication device that sends and receives audio or images using a telephone line is connected to either a subscriber's line or a dedicated line for communication via a line switching device, when the user wishes to use the dedicated line. In this case, the information communication device is provided with dial information sending means that inserts a pause in the dial information and sends the dial information as it is without adding a pause when the subscriber line is desired to be used, and the time interval between each digit of the dial information is set. a timer for measuring time; if the time interval is within a predetermined time, select a subscriber line as the line to be used; if the time interval is greater than or equal to the predetermined time, select a dedicated line as the line to use; and select the facsimile device. An information transmission system characterized in that the line switching device is provided with a control means for connecting to the line used by the user.
