Short cell multiplexing apparatus

摘要

A first header converting section outputs, when partial fill cells are inputted to the first header converting section , the partial fill cells, while converting a VPI of each of the partial fill cells into a value that is a unit of a multiplexing process at a short cell multiplexing section and converting a VCI of each of the partial fill cells into a value to be a CID which is to be stored in a short cell at the short cell multiplexing section. The short cell multiplexing section receives a plurality of the partial fill cells from the first header converting section to multiplex a plurality of the short cells within the partial fill cells for every VPI of the partial fill cells, and produces an AAL Type 2 cell in which the VCIs of the partial fill cells are stored as CIDs and the VPIs of the partial fill cells are stored as VCIs. A second header converting section receives the AAL Type 2 cell from the short cell multiplexing section and outputs the AAL Type 2 cell while converting the VPI/VCI of the AAL Type 2 cell into given values.
