AUTOMATIC BYPASS FOR COMMUNICATION NETWORKS

摘要

radio engineering; electrical (including digital) communications. SUBSTANCE: newly introduced in device is control unit enabling connection of communication line to normally operating communication center in case of failure of automatic bypass due to organizing direct circuits by third and fourth electronic switches in first connection unit and by fifth and sixth electronic switches in second connection unit. In this way open circuit in communication network due to failure of communication center or automatic bypass proper is eliminated. EFFECT: enhanced reliability of connections. 8 dwg
