ABSTRACT:
A system is illustrated that uses a spare or auxiliary add-drop muldem located at each end of N high capacity transport circuits to form a ring-type protection circuit using one additional high capacity transport. This is accomplished by using error detection circuitry to switch all of the auxiliary muldems to be normally in a high speed input/output circuit LOOPed condition but switching the auxiliary muldems on either end of a "bad" circuit to a THRU or open condition upon detection of a problem and allowing signals to be routed through the protection transport mechanism rather than the normal transport mechanism.
