Abstract

The purpose of the connection is a multipoint connection data and telephone dispatching stations operating in duplex on telecommunications circuit in such a way that reciprocal communication of all these stations according to the scheme, where the line station transmitter transmits a signal through the fork fork and the coupling fork simultaneously into the two opposite channels leaving the station and duplexing the receiver receives beech through hub fork and a coupling fork, or via a hub fork and coupler fork signal coming from one of the opposing incoming canals taking them, either through the fork or otherwise, through the forks, secured at the same time free passage of this signal over the line Wiring can be used to set up computer, terminal and processor networks arbitrarily multipoint exclusion structures needs of communication computers, in telephone dispatching and telemetry systems that require a high level of security against loss of information by influence interrupting the telecommunications link, e.g. along long-distance pipelines, major lines, traffic lines, for fast warning systems, etc.

Description

The invention solves the multipoint connection of telecommunica- tion stations working on duplex circuits so that it represents a telecommunication bus with the possibility of mutual duplex communication of all stations connected on this bus.

The prior art multi-terminal connection of stations to duplex telecommunications circuits does not allow them to communicate with each other without a computer connection. The previously known double-ring connections allow mutual communication in the case of signal transmission in analog form only by means of multiple transformation of analog signal to digital and vice versa. In all transmission methods, the message delay is proportional to the number of stations involved.

The above-mentioned drawbacks are eliminated by the connection of telecommunication stations operating duplex on multipoint circuits according to the invention, which is based on the connection of a station by means of a splitter splitting the signal of this station in the transmission direction through the splice forks. or in the other direction by means of the splitters of either one or the other side of the guide.

The above mentioned connection of the stations to the telecommunication circuit of any multipoint structure / e.g. tree, radial, combined / enables duplex communication of all these stations. It does not cause message delay and combines the benefits of multipoint and circular engagement. For circuits with a large number of duplex stations, it is possible to realize the branching by means of active forks and eliminate crosstalk between channels caused by lateral attenuation of the forks.

The attached drawing depicts the wiring of one line station, allowing the transmission of a signal to both sides of the multipoint circuit and duplex reception of the signal alternatively from one or the other side of the circuit.
