connected to the corresponding outputs of the counter, are informational outputs of the receiving and control unit.

FIG. 1 shows the structural electrical circuit of the proposed device; in fig. 2 is a block diagram of a reception and control unit.

The device for monitoring the operability of registers contains a reference register 1, a load analyzer 2 with a relay 3, a first group of closing contacts 4, a second group of closing contacts 5, a comparison unit 6, a receiving and control unit 7, which consists of a driver 8 of serial signals, a counter 9 of code pulses the receiver 10, the decoder 11, the switching unit 12.

The device works as follows.

During the occupation of one of the controlled registers 13 through the load analyzer 2, a sample of the reference register 1 is carried out. If the reference register 1 is free at this moment, it is taken from the load analyzer 2. At the output of the load analyzer 2, an actuating element is triggered, for example, one of the relay 3. In principle, any multichannel switching element, such as a relay, ISS, MGS, etc., can be used as actuating elements.

The closing contacts 4 and 5 simultaneously connect the input of the reference register 1 and the input of the receiving and control unit 7, respectively, parallel to the input and output of the controlled register 13. Information about the number of the called subscriber in the form of a series of decadal pulses (loop or battery) is fed simultaneously to the input of the controlled and reference registers 13 and 1. Since only the controlled register 13 participates in the process of establishing a connection, only this register transfers the transmission. In this case, linear signals, for example, sending a multi-frequency code or battery pulses, coming from its output into the transmission path, are in parallel received by the receiving and control unit 7.

From the output of the reception and control unit 7, information about each digit of the number is transmitted by a parallel code to the inputs of the comparison unit 6. In the reception and control unit 7, ten decadals are recorded by a counter of 9 pulses, and the frequency bursts are received by the code receiver 10 and decoded by the decoder 11, from which as well as from the output of the counter 9 pulses, arrive at the output of the receiving and control unit 7 connected to the input of the comparison unit 6.

The second group of inputs of the comparison unit 6 is received alternately (under the action of read control signals generated by the switching unit 12 of the receiving and control unit 7), the information recorded in the memory block of the reference

register 1. The control of the switching unit 12 of the receiving and controlling unit 7 is effected by signals generated by the shaper 8 of serial signals, when receiving at the output of a controlled register 13 decadal pulses or a decoder P, when receiving frequency signals. In the event of a fault in the controlled register 13, i.e., if there is a mismatch (unevenness) of signals arriving at different groups of inputs of the comparison unit 6, a corresponding error signal is generated at its output.

The proposed device allows you to reduce the amount of equipment due to the fact that the control process compares the information received at the output of the controlled register 13 and recorded in the memory block of the reference register 1. This simplifies the control of the reference register 1: you do not need to enter the transmission synchronization device, and in the receive block and control 7, station code receiver 10 may be used, which is involved in establishing connections.
