Methods and apparatus for communicating data between continuous bit rate trunk channels and a cell-based network are disclosed. The apparatus includes trunk interface circuitry, data interface circuitry, and cell segmentation circuitry. The trunk interface circuitry receives continuous bit rate call data that is being communicated from an originator to a recipient. The data interface circuitry is operatively coupled to the trunk interface circuitry, and is operable to receive the call data from the trunk channel and to extract an original data stream. The cell segmentation circuitry is operative to receive the original data stream from the data interface circuitry and to produce data cells. The invention also features methods of producing data cells. The method includes receiving continuous bit rate call data over a trunk channel, processing the call data to extract an original data stream that is being communicated from an originator to a recipient, segmenting the original data stream into cell payload data, and forming data cells that include the cell payload data.
