REMOTELY CONTROLLED CROSS COMMUTATOR Russian patent published in 1998 - IPC

FIELD: electric communication, commutation of channels and connecting lines for transmission of various information signals. SUBSTANCE: remotely controlled cross commutator has control desk, first and second storages, unit controlling switching, commutation field, AND and OR gates, flip-flop, indicating element. Novelty of commutator lies in insertion of unit controlling switching of decoder of numbers of channels, decoder of number of connecting line, pulse former, OR gates and encoder of number of connecting line into mix of control unit and in insertion of AND and OR gates with proper couplings in addition to polarized relays into mix of commutation field. EFFECT: simplified design of commutator and increased reliability of commutation due to exclusion of number of logic elements in mixes of commutation field and unit controlling switching. 1 dwg
