SU517175A1 - Telegraph station of decadal type - Google Patents

Description

one

The invention relates to telecommunications, can be used in telegraph stations for networks of various types (national and international) in the case of application on these networks of various types of signaling recommended by CCITT.

A decade-step type telegraph station, comprising successively connected preliminary and group search stages, whose connection circuits are connected to the corresponding inputs of the counting device, and the channel outputs of the group search stage are connected to the corresponding individual channel sets connected to the interaction signal converters.

However, a known telegraph station cannot provide interfacing with telegraph stations with alternating numbering.

The purpose of the invention is to simplify the equipment and provide interfacing with telegraph stations with alternating numbering.

In the proposed telegraph station between the preliminary and group stages

The search includes an additional interaction signal converter, the control inputs of which are connected to the corresponding outputs of the counting device.

A sensor for the typing signal can be connected to the signal inputs of the additional signal converter.

The drawing shows the structural scheme of the station.

Claims (2)

The telegraph station of the decade-schip type contains preliminary 1 and group 2 search stages, counting device 3, individual sets of channels 4, interaction signal converters 5 additional interaction signal converter 6, to which signal inputs 7 can be connected to the signal inputs. Additional interaction signal converter 6 is connected between the stages of preliminary 1 and group 2 search at the connection points of the inputs of the counting device 3 Control inputs of the pre the generator 6 is connected to the outputs of the counting device 3; Additional interaction signal converter 6 is designed to convert the type B signaling signals coming from the main communication section into the corresponding type A signals for the subscriber part of the communication, and the typed signal sensor 7 to transmit to the subscriber an additional literal signal of the invitation to dial the number. Works station as follows. To establish a connection, the subscriber dials the number using the disk in the usual way before going to the direction with an alarm type L or B / T. At the side of the adjacent station, a Call Confirmation signal is received, which is received by an individual set of channel 4 and not further transmitted. Signal A prompt for dialing a number that comes directly from a channel when signaling B / T or from an interaction signal converter 5 is received and decrypted by a counting device 3. After that, the counting device sends it through control circuits to an additional interaction signal converter 6. Transformer 6 disconnects the wires for receiving and transmitting the steps of the preliminary 1 and group 2 search. Its further operation depends on whether the sensor is a literal signal 7 or not. If it is used, converter 6 connects it to issue the invitation signal once to the dialing number over the receiving wire to the caller side and for one-time transmission over the transfer wire to the adjacent station of the translation combination to the digital register. After the transmission of these signals, the transmission wire is displaced, and a standing polarity signal is transmitted along the reception wire to the side of the caller and converter 6. If the sensor of the typed signal 7 at the station is not used, the converter 6 breaks only the reception wire and transmits the stop polarity signal to the caller side. Upon receiving the stop polarity signal by the subscriber unit, the telegraph motor starts, and the subscriber proceeds to dialing a number from the telegraph keypad. When a stop polarity signal is received from the channel or the signal converter of the interworking signal 5 (the Connection signal is established or an occupancy signal), the interaction signal converter 6 converges the receive and transmit wires. A sign of connection establishment for the subscriber is automatic receiving of the called subscriber. In the case of establishing a connection with the subscribers of the adjacent station, working with alarm B with disk dialing, blocks 6 and 7 do not participate in the station operation, since in this case the call confirmation signals and The invitation to dialing numbers is combined and not passed through by individual sets of channels 4. Claim 1: A telegraph station of a decade-step type, containing series-connected steps of the prefix the main and group searches, the connection circuits of which are connected to the corresponding inputs of the counting device, and the channel outputs of the group search stage are connected to the corresponding individual sets of channels connected to the converters of the interaction signals, so that simplification of equipment and provision of interfacing with telegraph stations with alternating numbering; between the preliminary and group search stages, an additional signal converter is used actions, the control inputs of which are connected to the corresponding outputs of the counting device. 2. A telegraph station according to claim 1, characterized in that an alphabetic signal sensor is connected to the signal inputs of the additional interaction signal converter.
