Paper Abstract

Existent methods of suppression of echo nuisance influence (methods of echo obstruction, echo compensation and self- balanced differential system) have their both advantages and disadvantages. For example widely used on USA and European networks echo compensator with higher subscriber transmission quality estimation then echo obstructer is not operable on significant part (20%) of Russian networks echo paths. Mentioned problem can be solved either by complication of echo suppressors technical realization under not guarantee of their 100% operability or by creation an echo suppressor of combined type. Combined echo suppressors must have positive properties of existent echo suppression methods. Methods of combined echo suppressor realization are considered. In addition an evaluation of their perspectives is done from the point of view of provided transmission quality.
