Equipment for multiplexing multichannel radio-relay lines of communication

The equipment is intended for organizing six hf telephone channels in the frequency range of 4 to 32 kHz in a single-band four-wore system. The channels of the equipment are intended for use in a system of rural communication as connecting lines between terminal RTS and ATS, and also for organizing the automatic transit through ATS. Depending on the type of tandem ATS the automatic connection of channels can be realized in two-wire and four-wire systems. The equipment provides the opportunity of secondary multiplexing of channels.
