Abstract:
A packet multiplexer for multiplexing communication channels containing C-planes and U-planes, comprising:a plurality of first communication interfaces for terminating a plurality of C-plane and U-plane pairs on one side of the packet multiplexer, each first communication interface terminating a pair of C-plane and a U-plane;a second communication interface for terminating a single C-plane and a plurality of U-planes on another side of the packet multiplexer;a connection interface for multiplexing the plurality of C-plane and U-plane pairs terminated at the plurality of first communication interfaces into the single C-plane and the plurality of U-planes terminated at the second communication interface; anda control unit for controlling multiplexing the U-planes by the connection interface according to signaling through C-planes, such that a cut-through is made within the packet multiplexer between two U-planes terminated at the first communication interfaces that form a loop.
