ABSTRACT:
A method and apparatus for implementing intelligent priority functions at individual switching apparatus devices which comprise switching networks. The intelligent switching functions are capable of operating in real time systems with high efficiency. The switching apparatus has the capability at each stage of the network to make and/or break connections on a priority basis. If a connection is requested at a switch stage and the connection is being used by a lower priority device, the low priority connection is interrupted (broken) and the requested higher priority connection is established. After the high priority connection has completed its usage of the connection, the high priority connection is broken and the lower priority connection is re-established.
