Fig. 1 The invention relates to telephony, in particular, to battery transmitting devices, receiving signals of interaction in an incoming device of a conversation path during inter-office communication via a long-distance cord, and can be used in various conversational path devices (sets) coordinated by connectors. lines with station devices. . The purpose of the invention is to simplify the device by reducing the number of switching elements. Fig. 1 shows a skeletal diagram of the organization of communication between the automatic telephone exchange and the PBX when establishing an incoming long-distance connection to subscribers of the rural and urban telephone network; in fig. 2.- functional diagram of the device for battery transmission and reception of interaction signals in the input device of the spoken path. As a sl-out from FIG. 1, the outgoing coordinator combo SU 2 is set up at the outgoing telephone station of the automatic long-distance telephone station AMTS2, intended to include the outgoing local telephone (for example, PBX A3) inter-station communication lines that go to the local (urban and rural) telephone network . At the opposite end of this area of inter-office communication, incoming matching sets of RSLV 4 are established. Establishment of incoming long-distance connections to subscribers 5 of ATS A3 is carried out through one inter-station communication section between AMTS 1 and ATS A3. For subscriber 6 PBX B7, similar connections are established through two sections between the station communication. At the same time, the ends of both sections are equipped with incoming radar sets (RSLV 4 and RCLI 8). Functionally, each set of RSLVs can be represented as two parts 9 and 10. Part 9 provides interaction through an inter-office communication link with an outgoing matching set installed at the outgoing end of the connecting line. Its implementation is determined by the type of inter-station communication line (physical or compacted) and the method of transmitting interaction signals over a given line. Part 10 is intended for interaction with station instruments with a special-purpose and CODE adopted for in-station sections of communication paths. The proposed device (Fig. 2) refers to the part 10 of incoming sets, the device contains a receiver 11 signals from the subscriber via wire C, a receiver 12 signals from the subscriber via wire b with its blocking element 13, a receiver 14 signals through the reception channel and its executive element 15, the actuating element 15 of the receiver. 14 is located in a single circuit for transmitting ringing and resetting signals to the subscriber side of positive polarity via wire b, connecting receiver 12 to this wire. The proposed device can be implemented on standard telephone relays with contacts in the locking, transmitting, receiving circuits and broadcasting, as well as with the help of electronic devices, when electronic receivers control the corresponding electronic actuator circuits. The device works as follows. If the called subscriber is free, the station devices receive constant positive polarity along the wire d and negative polarity along the wire t perceived by receivers II and 12. The actuating element of the receiver 12 (not shown) provides the signal Caller's free to the channel. Upon receipt of an unattended subscriber signal from the AMTS to the AMTS, the ringing signals begin to appear, as a result of which periodic positive-polarity sprinkles are received through the receive channel perceived by the receiver 14 of the device. The executive element (contact). 15 of the receiver 14, these signals are transmitted towards the station devices, in the form of positive polarity, and are perceived in the subsequent station device by a single receiver (and the call signal, and

reset signal). Since the receiver 12 is disconnected from the wire t when applying these signals (to eliminate its influence on the reception of transmitted signals at the opposite end), it is necessary to ensure that it is blocked for the duration of the call dressing signals. This blocking (holding) is provided by the blocking element 13 of the receiver 12.

Upon receipt of the called subscriber's busy signal (the negative of the polarity of the wire, b), received by receiver 12, the ne circuit, the transmission of this signal towards the receiver.

It is not shown) from the AMTS side, the device starts receiving a reset signal in the form of positive polarity parcels through the prism channel. Like the ringing signals, these signals are sensed by the receiver 14 of the device and its contact 15 is transmitted via wire b in the direction of the station instruments in positive polarity. Keeping the receiver 12 in the bob state at the time of the signal data, i.e. at the time of disconnecting the receiver 12 from the wire b, the lock element 13 is also implemented.
