Abstract: A switching system is disclosed in which junctor circuits intermediate two stages of a switching network provide the sleeve lead holding ground for established network connections. The use of the junctor circuits to maintain an established connection, rather than one of the end circuits connected to the network, permits a plurality of network paths to be in existence concurrently to a circuit having a single network appearance. Each path may be released independently of the other since the sleeve leads of the concurrent paths remain independent of each other.
