the RS stage controlled by block 25 connects the incoming cord set to the register of station B via block 20, after which the telephone channel is connected to the next station through the switching field and the control signals are exchanged between the registers of station B and the next station , 22 and 26. In block 23, linear signals are generated and transmitted to the switching field through block 22 and block 26. Linear signals entering the device from the switching field of station B are perceived mayuts unit 24 and then through the unit 18 are translated in a line directly without recognizing that facilitates reception of signals from a switching field and their transfer towards the line. In the outgoing cord set, the signals coming from the line to the conversational state are transmitted to the switching field of station A without recognition, and the signals pass through block 12, block b, block 3 and block 1. In order to prevent transmission to the switching field of short-term signals (interference) arising in the conversational state in subsequent switching sections in the outgoing cord set, block 7 is inserted, containing an electronic time delay, which selects signals by duration and protects the circuit in uchae momentary arrival signal (noise). To compensate for the attenuation and non-uniformity of the frequency response that the inter-station line introduces into the receive path, the device has blocks 5 and 21 containing an equalizer amplifier included in the receive path from the physical line. In order to control the breakage of lines in the device in the initial state of the sets, when the power is turned on, if the inter-station line in the block 9 and block 16 is working, the control relays operate. In the event of a break in the initial state, the pairs of wires or individual wires of the line in the sets form a blocking signal, which is transmitted to the memory of the switching field of station A, and the technical fault signaling is turned on. The device works similarly in the case of monitoring wire breaks in the occupied state of the kit and the grounding of the wires of the line; in this case, the line is monitored in the first case by blocks 10 and 16, and secondly by blocks 11 and 15.
