    摘要: A packet telephony appliance includes a Euphony network processor that integrates networking and DSP functions to provide a low cost and efficient solution in building a networked appliance. In particular, a Euphony ATM Telephone (EAT) is built around the Euphony network processor. The EAT uses a real-time operating system to provide predictable processing and networking support. The EAT implements IObufs, which provides a unified buffering scheme that allows zero-copy data movement. Furthermore, the EAT uses an Event Exchange (EVX), which provides a flexible mechanism for event distribution, allowing software modules to be composed together in an extensible manner. EVX and IObufs are used together to provide highly efficient intra-appliance communication. The EAT provides a platform that can evolve gracefully to support new protocols, advanced telephony services and enhanced user interfaces.

    摘要: Method and device provide for the encapsulation of control information in a real-time data stream. In one embodiment a method of encapsulating data in an information frame is provided. This information frame has a payload portion and a trailer portion wherein the trailer portion is designated for control data and the payload portion is designated for real-time data. In use control data is inserted into the payload portion of the information frame and an extension bit is used to signify the presence of control data in the payload portion of the information frame. The information frame is then transmited over a virtual circuit.
