Abstract
PURPOSE:To secure the privacy even in case of interception while assignment of a periodic time slot is not required by informing information relating to a time slot number for line exchange and the order of use of the time slot from one station in advance through a channel for inter-station control. CONSTITUTION:The information relating to the time slot number carrying a communication data for line change and to the order of use of the time slot is informed from one station 130-1 to the other station 103-2 in advance through a channel for inter-station control between both receiving terminal stations of a multiplex transmission line 104. Then the controlled station at the receiver side determines the assigned order of the time slot at the reception of the communication data for line exchange in one frame by using the control information. Thus, the timewise sequence of the time slot is not according to the sequence of data production in the multiplex line 104 and the assignment of the time slot is not periodic.
