multichannel communication systems; multichannel time-division portions. SUBSTANCE: echo compensator that has linear driving interfaces, synchronizing-frequency regeneration and separation units, frequency standard, and echo compensator unit is provided, in addition, with reference time-step switch, channel multiplexer, channel separator, two inhibit circuits, backup bit buffer, accident control unit, and microcontroller. Starting baseband echo compensator installs its operation program. Accidents caused by defective components of echo compensator or channels invokes signal transmission inhibit and reinstallation of program wherein changes in setting parameters can be introduced. EFFECT: enhanced operating reliability and performance characteristics of echo compensator. 3 cl, 1 dwg
