The power supply is not shown in the drawing, but it produces voltages of 5 V and 60 V and a buzzer signal with a frequency of 450 Hz and an inductor signal with a frequency of 25 Hz.

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 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 connect individual subscriber telephones to the steps of a group search of ATS of a ten-step and coordinate systems that are not equipped with real-time subscriber search equipment. This allows you to expand the functionality of the device.
