  • Patent number: 8599846
    Abstract: A data and voice communication system includes communication between a line card and an accelerator card. Voice, data, and control traffic is received from the line card and is transmitted to the accelerator card via a physical link having separate voice, data, and control logical channels. The separate voice, data, and control logical channels are represented by labeled data packets.

  • Patent number: 8441920
    Abstract: A method includes receiving information at an interface circuit and providing the information from the interface circuit to a processing circuit through a direct communications path between the interface circuit and a processing circuit, which processes the information received from the interface circuit. The method further includes providing the information from the interface circuit to the processing circuit via a crosspoint switch in response to a failure of the direct communications path, wherein the direct communication does not pass through the crosspoint switch.
