Abstract
A subsystem for communicating a private network signalling message over a packet network and bridges for communicating a Media Access Control (MAC) layer frame over an isochronous channel and for communicating an isochronous signalling frame over a nonisochronous network. The subsystem comprises: (1) an encapsulation circuit, coupled to a transmitting user station, capable of receiving the private network signalling message from the transmitting user station, the encapsulating circuit encapsulating the signalling message within, and adding source and destination addresses to, a routable protocol frame, the source and destination addresses corresponding to addresses of the transmitting user station and a particular receiving user station, the encapsulation circuit queuing the routable protocol frame for transmission over the packet network and (2) a de-encapsulation circuit, coupled to the particular receiving user station, capable of receiving the routable protocol frame, the de-encapsulation circuit extracting the signalling message from the routable protocol frame, the packet network thereby simulating a point-to-point connection between the transmitting and particular receiving …
