Device for steaming paired subscriber lines

This utility model relates to communication technology and can be used to automate communication of small automatic telephone networks

A device is known (RF patent 2125345, class N04M 9/00, publ. 1999), expanding the volume of the subscriber telephone network

The known device does not provide the ability to pair paired telephone subscribers

The objective of this utility model is to enable all subscribers of automatic telephone exchanges (ATS) of a ten-step and coordinate systems to independently connect to a public telephone exchange

The technical result consists in expanding the functionality of the device

The result is achieved in that in a device for steaming paired subscriber lines, including a power supply generating unit, configured to generate the required power supply voltage of telephone units, a control and diagnostic unit configured to generate test and control signals for individual units and units of the device, communication units with subscribers, configured to provide communication with individual telephone sets, a multiplexer configured to separate the time of connecting the given telephone sets and the corresponding communication units with subscribers to work with the device, a common communication bus configured to exchange signals between nodes and units of the device, signal processing units of subscriber lines made with the possibility of converting the format of the analog signal and its coding, input signal processing units

connecting lines, configured to receive signals from the telephone exchange and their coding, and signal processing units of output connecting lines, configured to decode data from subscribers and transmitting them to the city telephone exchange, the control and diagnostic unit is made with the additional possibility of generating test and control signals for the entered blocks, the multiplexer is made with the additional possibility of separation in time of the connections of the specified connecting lines g city telephone network to work with the device.

All blocks and nodes of the device are made using standard elements of radio electronics, telephony and computer technology.

The device operates as follows.

The device is connected via outgoing communication to the first stage of the GATS group search and via incoming communication - to the linear search stage. It provides all the functions of the subscriber search stage. The capacity of the basic version of the device is 256 subscriber ports, 16 ports of incoming communication, 16 ports of outgoing communication, 8 ports of long-distance communication. The device allows for the conversion of signals from subscribers to the common bus format, their processing, the conversion of processed data from the common bus format to the signals of the outgoing GATS trunk lines and the transmission of messages to the city telephone network. Similarly, the reverse procedure is performed. The equipment allows you to perform in real time for all subscribers. This allows you to expand the functionality of the device.
