Abstract
A multi-access transmission method for effectively and efficiently utilizing bands of a synchronous digital hierarchy (SDH) path. The method has the steps of extracting a synchronous digital hierarchy path from signals input from a first point, recognizing all packets or cells input from the first point to select and drop a packet or cell to be dropped at a second point, multiplexing packets or cells not dropped and a packet or cell to be inserted at the second point at a packet or cell level, and sending signals created at the multiplexing step to a third point. With this method, packets or cells are multiplexed in a synchronous digital hierarchy path to share one synchronous digital hierarchy path among a plurality of communications.
