  • Communication device
    Patent number: 7542480
    Abstract: In a communication device which can realize a protocol conversion by a single device without preparing respective packages for existing various protocols, a protocol attribute included in a packet received is detected, protocol processing order data indicating a protocol processing order based on the protocol attribute are generated, and a plurality of protocols within the received packet are processed based on the protocol processing order data.
    Type: Grant

  • Method and apparatus for switching signals of multiple different communication protocols
    Patent number: 6498792
    Abstract: A telecommunications switching apparatus (10) includes optical paths (16-19) coupled to interface cards (26-29), which in turn are coupled to a switching circuit (41-42). The switching circuit is coupled to a plurality of universal connectors (71-74), each of which is coupled to an auxiliary connector (77-78). The universal connectors can each removably receive any one of several types of switching circuit cards (101-104), which each utilize a respective one of several different communication protocols. An auxiliary circuit card (107-108) may be provided in the associated auxiliary connector, in order to support switching circuit cards that use certain communication protocols. The optically transmitted information includes segments formatted according to respective communication protocols, and is converted from optical to electrical form by the interface cards.
