Abstract
A cross-connect switch () uses a matrix () for providing connection paths. The matrix () includes prioritization logic () for receiving connection requests from restoration state machines () (for changing connections responsive to line conditions) and an administrative processor (for changing connections responsive to operator commands). Connection requests from both the restoration state machines () and the administrative processor () are cached in FIFO memories (). When a FIFO memory () stores one or more connection requests, the switching control circuitry is notified by a data ready signal. Logic () inhibits passing of the data ready signal from the FIFO memory () to the switching control () until all restoration connection requests have been serviced.
