  • Frame relay access device with user-configurable virtual circuit bundling
    Patent number: 6278708
    Abstract: An apparatus and method for bundling frame relay packets under one or more common DLCIs. A plurality of frame relay packets is received in a frame relay access device. A common bundling DLCI is associated with each of the frame relay packets based on a configuration parameter that can be modified by a human operator to have at least a first state or a second state. When in the first state, the configuration parameter indicates that the common bundling DLCI is included in voice frames generated in the frame relay access device. In the second state, the configuration parameter indicates that the common bundling DLCI is not included in voice frames generated in the frame relay access device. Each of the frame relay packets has an initial DLCI which is used to determine a multiplexing value. Each of the frame relay packets is transmitted over a frame relay network using the common bundling DLCI and its respective multiplexing value.
