The device is applicable for computation equipment for data exchange between I/O channels of multiunit networks with a number of remote terminals, terminal stations or other computing systems. It ensures the simultaneous operation of more than two I/O channels with enhanced speed of exchange between the remote users and a multi-mechanical network, so that every user can independently switch over to one of the I/O channels. The device consists of four units for connecting to I/O channels (1.1, 1.2, 1.3, and 1.4), and of four priority switches (2.1, 2.2, 2.3, and 2.4). Each switch consists of a unit for registration of interruption, coding and priority comparison unit (3), a synchronizing unit (4) and a unit for priority registration and priority selection.
