Logical coupler in a telecommunication network

摘要

The logic coupler has two wires connected to modules functioning at the same rate with identical communication protocols, and connected to a line drive transcoder. The differential signals circulate on the bus as logic signals. <??>There is a logic locking system (2) transferring the document bits to state 0 for the first bus reception line to the other bus, in forcing the transmission line of the first bus to a recessive logic level to state 1 such that the reception line associated is in the dominant state in managing collisions maintaining the dominant level preset on one of the reception lines of the priority coupler on the two transmission lines of the coupler.
