TELEPHONE COMMUNICATION CONCENTRATOR Russian patent published in 2018 - IPC H04Q3/58 

FIELD: communication equipment.

SUBSTANCE: invention relates to the electric communication equipment, and can be used for establishing of operational telephone and process communication between both the fixed network subscribers and located in mobile objects subscribers. Said technical result is achieved by the fact that in the telephone communication concentrator containing n telephone sets of the concentrator subscribers (local subscribers), linear unit, which includes a switching system with n subscriber sets and the functional relays unit; and the linear unit additionally comprises a control unit, switching system control device, cords set, call signal generator, the functional relays unit emergency switching element and the functional relays unit separating switching element, and to the concentrator n connecting lines, the station unit are additionally introduced, which subscriber lines are connected to the reference automatic telephone exchange (PBX) subscriber sets, at that, each local subscriber’s telephone set line inputs / outputs are connected to the line unit switching system corresponding line inputs / outputs, each of the n subscriber sets is connected to the switching system corresponding subscriber input / output by the first input / output, and through the functional relays unit corresponding emergency switching element is connected to the corresponding connecting line first input / output, and by its second input / output each connecting line via the functional relays unit corresponding dividing switching element is connected to the switching system station inputs / outputs first group corresponding input / output, switching system station second inputs / outputs are connected to the cord set first inputs / outputs, which second inputs / outputs are connected to the switching system control device first inputs / outputs, which second inputs / outputs are connected to the control unit control inputs / outputs, the switching system control system control output is connected to the switching system control input, linear unit switching system each subscriber set information output is connected to the control unit corresponding information input, which first control output is connected to the cord set first control input, which second control input is connected to the call signal generator control output, control unit second control output is connected to the functional relays unit control input, which control outputs first and second group are connected to the functional relays unit emergency and isolation switching elements control inputs, respectively, with its third input / output each connecting line is connected to the station unit corresponding input / output.

EFFECT: technical result consists in the concentrator functionalities expansion to provide the telephone communication between local subscribers and to enable the possibility of the local subscribers automatic access to the public telephone network.
