information, while the first and second outputs of each display speed controller are connected respectively to the input of the first and second code converters of the corresponding element of the communication node, and the input and third output of each display speed controller are connected respectively to the output and the first control input of the corresponding memory block whose signal input is connected with the corresponding output of the information distributor, the first and second signal inputs of which are connected respectively to the outputs of the register of numbers a onenta and channel number register, a signal input coupled to the second output array of channel numbers of the counter, the decoder output is connected to the input of the channel switching, and the control input of the combined distributor informatsii.i second control inputs of the memory units are connected to the sensor output control signals.

The drawing shows a structural electrical circuit of the proposed device.

The device displaying the switching state of the communication channel of the communication node contains the central element of the communication node 1 and the channel-forming elements of the communication nodes 2, each channel-forming element of the communication node 2 and the central element of the communication node 1 consists of an indicator of channel number 3, indicator of subscriber number 4, two code converters 5 and 6, display speed controller 7 and memory block 8, in addition, the central element of communication 1 contains a sensor 9 control signals, a counter 10 of the array of channel numbers / decoder 11, a switching unit of 12 channels, a block defined the established connections 13, the encoder 14, the subscriber number register 15, the channel 16 register • and the information distributor 17.

The device works as follows.

The first control signal of sensor 9, the contents of counter 10 of the array of channel numbers is entered into the channel number register 16 and simultaneously through the decoder 11 the channel number enters the established connection determination unit 13. The established connection determination unit 13 determines the subscriber number that is connected to the channel recorded in the counter 10. If the connection exists, the second control signal found number is entered in the register number of the subscriber 15. If the channel number is recorded in the counter 10, is free, then Subscriber number register 15 is not recorded ..

The third control signal reads from the register the channel number 16 and the subscriber 15 to the information distributor 17, the fourth control signal goes to the information distributor 17 in memory block 8, providing reading information from key information distributor 17 circuits and writing it to memory block 8 the central element of the communication node 1 and the memory block of that element of the communication node, which formed the channel with the number recorded in the counter 10.

The fifth control signal sets the registers of channel numbers 16 and subscriber 15 to the “0” position, and adds “one” to the counter 10 of the array of channel numbers, i.e. forms in the counter 10 a new number that enters through the decoder 11 into the block for determining established connections 13, etc.

The rate of receipt of control signals is selected based on the speed of changing the communication channel switching of the given communication center.

Information from the memory blocks of 8 communication node elements is fed through the display speed controllers 7, each of which consists of the control pulse generator and key circuits, and through code converters 5 and 6 to the channel number 3 and subscriber number 4 indicators.

The mode of displaying information (speed, volume, sequence) is set by operators of the elements of communication nodes using display speed regulators 7.
