Abstract:
An apparatus at a customer premises site for communicating data across a network using a packet switching protocol, comprising:at least one identifier being carried with the data to identify the data as belonging to at least one first virtual circuit, the at least one identifier being carried with the data on at least part of the at least one first virtual circuit; a first port for communicating said data, the first port comprising the at least one first virtual circuit that is statistically multiplexed on the first port to carry the data, the first port providing connectivity to a customer premises equipment; a second port for communicating said data, the second port comprising at least one switched virtual circuit that is statistically multiplexed on the second port to carry the data, the second port providing connectivity to said network; a processor; and a memory containing a first code segment for execution by said processor, said first code segment configured to connect said first port comprising said at least one first virtual circuit communicating said data with said second port comprising said at least one switched virtual circuit for communicating said data across said network to a destination, said first code segment configured to connect the at least one first virtual circuit in said first port with the at least one switched virtual circuit in said second port based at least upon a detection of a condition, the at least one first virtual circuit being presented as active on the first port for carrying the data prior to communication of an SVC call setup signaling message between the apparatus and the network, the SVC call setup signaling message for call control to activate the at least one switched virtual circuit in the second port for carrying the data between the apparatus and the network, the SVC call setup signaling message and the condition being causally related.
