condition. The zero potentials from the direct outputs of the flip-flops of the group of flip-flops 5 affect the corresponding inputs of the element OR 9.- The known inputs of the prohibition elements of the group of the prohibition elements 2 are opened with low potential from the output of the element OR 9. The device is ready to accept service requests. .

Suppose that a group of inputs 14 of the device received applications from the first, sixth and tenth subscribers. The number of subscribers connected to the device is 10. Let

References, a group of inputs 14, ... 14 per - binary - code recorded in the first revocation of the device.

Block 1 of the registers is intended for use before starting the operation of the device of subscriber numbers in binary code. Recording is performed in order of decreasing subscriber priorities. The number of registers in a register block is determined by the number of subscribers connected to the device.

The input 12 of the subscriber codes record records the subscriber codes in the register block in order of decreasing subscriber priorities.

During the operation of the device, when the priorities of the subscribers change, the codes of the subscribers are rewritten in accordance with the new priorities of the subscribers. The group of inputs 14 receives applications from subscribers for servicing.

The group of multiplexers 3 is designed to pass applications to the single inputs of the triggers of the group of triggers 5.

The device works as follows.

Before the device starts its operation, the input 12 of the subscriber codes is recorded in the subscriber order in order of decreasing priorities in the registers of registers group 1. The first register 1 records the subscriber's binary number, which has the highest priority at that time, in the last register 1 - number of the subscriber with the lowest priority. Triggers group triggers 5 are in zero

while in the given time interval, the priority of the sixth subscriber is 1, the first is 4 and the dext is 5, i.e. Shes-

That subscriber has the highest priority. Number of the sixth subscriber in

registrar block registers, the first subscriber - in the register S S of the ten subscriber - in the register C.

Received applications will go through the open first, sixth and tenth elements of the prohibition of the group of elements 2 of the prohibition and arrive at the corresponding mjie information inputs of all multiplexers of the group of multiplexers 3.

 The request from the sixth subscriber will pass to the output of multiplexer 3 (since the address on the address inputs of the multiplexer, which is supplied from the outputs of the first register bits

5 blocks of registers for the address inputs of multiplexer 3 (.

Similarly, the application of the first subscriber will pass to the output of the multi-. 34, and the application from 10 subscribers will pass to the multiplexer 3 output. The unit potentials from the outputs of the multiplexers 3, 3, 35- are set:, the triggers 5, 3A, and 5c are new to the single state. In this case, the unit:

 55, the potential from the output of the element OR 9 closes all the elements 2 of the prohibition for further reception of the call from subscribers. Trigger 5 | its inverse output will block all subsequent

0 elements and 6 corresponding to the applications with a lower priority. A single potential from the output of the trigger 5 passes through the element I in to the control input of the block of elements

5, the first inputs of the block elements And 7 ,, ... 7, are affected by the signals from the outputs of the bits of the register I,. The subscriber number appears at the input of the block of elements 7.1 ... 7, ffl

in the binary code for which it is served. This code is fed to the corresponding inputs of the decoder 8, at the outputs of which the address

the subscriber, for which the service provider is 5 ° of the group, is connected to zero points.

the tribute of the corresponding group triggers, a single output i-ro (, ... n, n is the number of sanpocois) group trigger is connected to the first input of the i-th elePo the request to the sixth subscriber is sent to the corresponding output of the output group 10 of the device. When the answer is received from the sixth subscriber by the pulse of the Yu ment And the second group, the second and the input 11 of the device poll, the following inputs of the i-ro element And the second group (,, .., n) are connected to the inverse outputs from the first (-1 ) -th group triggers, and the second t5 input of the first element And the second group is connected to the expansion input of the device, the control inputs of the group inhibiting elements are connected to the output of the OR element, which differs.

Their first inputs are connected with so-called 20 so that, in order to increase the DOS-response with the remaining bits of the register 14, to the operation of the device, into it the block 1 of registers. A group of multiplexers are entered on the corresponding-.s. A group output of the device's output group 10 is sent to the first subscriber. After receiving the answer. From the register of the group is connected to the input by a pulse at input 11 through the house of recording the device codes, the output

5 (through the element And f is shrunk to the zero state. A single potential from the inverse output of the trigger 5 opens the second inputs: the elements 6 and 6, etc. The application from the first subscriber from the direct output of the trigger 54 passes through the element 6 to the control input of the block of elements And 7,

a register of registers, a group of blocks of elements AND, a decoder, and the input of each element AND 4 of a flip-flop 54 is reset to zero. The high potential from the inverse output of the trigger 5 opens the fifth inputs of the elements I-6., 6g, 6, etc.

Further work is similar.
