  • Frame relay system capable of handling both voice and data frames
    Patent number: 5303237
    Abstract: Modifications to existing frame relay communication protocols are described which permit both voice and data frames to be handled in an integrated frame relay system. A Voice Frame Identifier bit is defined in the address field of a frame. When an intermediate node detects a voice frame, a CRC operation is performed using only the frame header; that is, voice information is excluded from the computation. The frame is flagged for priority processing in the node. When the intermediate node detects a data frame the CRC operation uses both the header and the data fields.
