Abstract :
This is a fault-sensing and switching system serving as an automatic guardian of the quality of a broadband (1,300 kc) transmission channel. Acting upon a loss in transmission level or an increase in noise, it transfers a communication traffic load from a failing regular channel to a normally unassigned standby channel. Protection afforded by standby channel can be shared by three regular channels.
