Abstract

A multi-mode signal transmission processor uses a transmission convergence layer technique, a frame technique, and a forward error correction technique to perform signal conversion and transmission between a transmission protocol layer and a physical medium-correlated layer, and is capable of handling a plurality of transmission modes. The invented multi-mode signal transmission process mainly includes: a transmission convergence layer module; a frame module; a forward error correction module; and a controller module; in which the transmission convergence layer module is used to process the transmission protocol layer signals and is capable of processing asynchronous transmission mode signals and packet transmission mode signals. The frame module is used to package data into a frame or retrieving data from a frame, and is applicable on a digital user loop, e.g. asymmetrical digital user loop, ultra-high-speed digital user loop, etc. The forward error correction module uses a Reed-Solomon Codes and convolution interleaving technique and is capable of correcting errors in a physical medium-correlated layer signals. The controller module is used to control the operations of other modules. Through an assembly of the above-mentioned modules, a multi-mode signal transmission process of the invention is produced.
