Abstract

A system for linking channel groups from various data terminals in a sending station to corresponding data terminals in a receiving station, via digital telephone switching networks. Orderly connection of channels, maintaining the space order and time phase between channels of the group, is accomplished by providing a group trunk (as named by the inventors) in each terminal station, to connect the data terminals to the telephone network. The group trunk establishes the necessary number of channels between the sending and receiving stations. The group trunk of the sending station provides data to be transmitted with a channel identification code, with which the data is transmitted. The group trunk of the receiving terminal detects the channel identification code of the received data, then rearranges the channel paths of the receiving terminal, and equalizes the delay time of each channel.
