AUTOMATIC DEVICE TO BY-PASS ELEMENTS OF WIRE COMMUNICATION NETWORKS Russian patent published in 2000 - IPC

FIELD: radio engineering, electric communication. SUBSTANCE: invention can be used both in digital and analog communication networks when it is necessary to by-pass intermediate element of network that has failed. Characteristic feature of invention lies in that if communication center B fails translation of signals is ensured from communication center A to center C with by-pass of center B and back over transmission lines thanks to cut-off of key center B, its blocking by first, second and third electronic switches and by cut-in of stand-by center B instead of it. EFFECT: provision for high structural reliability of communication network if intermediate line communication center fails. 5 dwg
