PURPOSE:To increase the line accommodating efficiency and to enable to connect and control a lot of data terminals, by connecting an arbitrary data communication line to an arbitrary communication controller with a communication request from a respective data communication line. CONSTITUTION:The system consists of a line connection path switching device SU accommodating a plurality of data communication lines D1-DM and enabling to connect a plurality of data communication lines D1-DM to arbitrary communication controllers 1-n, and a line control and connection device CU monitoring the data communication lines D1-DM and controlling the operation of the device SU. The communication request from the lines D1-DM connect arbitrary communication lines D1-DM to arbitrary communication controllers 1-n. Thus, a lot of data terminals can be connected and controlled with a comparatively few controllers 1-n. |
