PURPOSE:To automatically assign time slots having correct connection even if bypass connection exists by adding a specific system number to each time division multiplexer in the entire network and giving a virtual line number at a passing station to a line connected via plural stations and registering connection destination information to said line. CONSTITUTION:System numbers SYS1, SYS2, SYS3 are given respectively to time division multiplexers 2, 4 and 6. In applying the connection shown in figure, tentative line numbers BYP1, BYP2 and BYP3 are given to bypass lines respectively connected between the time division multiplexers 2, 6 by the time division multiplexer 4, and as the connection information, a system number and a low speed line number of a start station and a system number and a low speed line number of an end station are stored respectively. In order to specify the order of time slot assignment, the rearrangement is executed by using the line speed and the line number. In this case, the SYS number of its own station and the SYS number of the line connection destination in the connection parameter are compared and the comparison is executed by using the line number having the smaller SYS number.
