The input highways 10 and 20 are connected to the switches 1 and 2 in multiple ways. Since switches 1 and 2 have the same configuration, switch 1 treats highway 10 as highway numbers 0 to n/2-1 and highway 20 as highway numbers n/2-n-1. In the switch 2, the highway 10 is treated as highway numbers n/2 to n-1, and the highway 20 is treated as highway numbers 0 to n/2-1.

Highways 10 and 20 are multi-connected to switches 1 and 2. Reference numeral 3 denotes a control device for controlling the connection of the input/output highways housed in the switches 1 and 2, and 30 is a control information line thereof, through which the same control signal is supplied from the control device 3 to each of the switches 1 and 2. The control signal for switch 1 is edited by a bit inversion editing circuit 12 provided in the control signal receiving section, and the control signal for switch 2 is edited by a bit inversion editing circuit 22 provided in the control signal receiving section. . This digital control signal is in binary representation, and the specific bits of the control signal are highways 10 and 2.
It has a function of grouping 0. In other words, the binary representation of the control signal specifying the incoming highway is a o-1 a o-2 ...
a l …a 1 a 0 , and the incoming highway number H is H=a 0 ×2 0 +a 1 ×2 1 +…+a l ×2 l +… +a o-2 ×2 n-2 +a o-1 × 2 n-1 . Let l be the inverted representation of a specific bit a l ,
The binary representation of the control signal specifying the incoming highway by specific bit inversion is a o-1 a o-2l … a 1 a 0 ,
The incoming highway number by inverting the specific bits is =a 0 ×2 0 +a 1 ×2 1 +...+ l ×2 l +... +a o-2 ×2 n-2 +a o-1 +2 n-1 .

If a l = 0, then l = 1, and if a l , then l = 0, so =H−a l ×2 l (a l =1) =H+ l ×2 l (a l =0) 2 If we choose a l where l = n/2, then 0<i<n/2
For incoming highway number i of −1, a l =0,
The incoming highway number i′ by inverting the bits of a l is i=
It becomes i+n/2. Also, a l = 1 for the incoming highway number i where n/2<i<n-1, and the incoming highway number i'' by bit inversion of a l is i'' = i-
It becomes n/2. Therefore, the corresponding specific bit is not inverted in the bit inversion editing circuit 12,
The bit inversion circuit 22 inverts the bit. As a result, highway 10 in switch 1 is treated as highway number 0 to n/2-1, highway 20 is treated as highway number n/2 to n-1, and in switch 2, highway 10 is treated as highway number 0.
~n/2-1 highway 20 is treated as highway number n/2~n-1.

As explained above, according to the present invention, when a plurality of the same devices are used to configure a device of the necessary scale,
There are advantages in that it is economical in terms of hardware used in the same device, and that digital control signals for setting time-division communication paths for devices of different sizes can be unified. In addition, since the present invention is provided with a control signal bit inversion editing circuit in the controlled device, there is an advantage that the controlled signal can be edited by the controlled device, and it is possible to economically switch the time-division communication path by using a small unit switch. and can be used to simplify path setting control.
