Abstract
A physical medium dependent (PMD) transport subsystem is disclosed which is used in an xDSL communication system. The PMD subsystem coordinates movement of data from an analog front end to a logical pipeline based TC layer, and exchanges common data objects with the latter to increase flexibility of the system. The PMD subsystem includes a number of ASIC blocks for performing signal processing operations, and these ASIC blocks are also shared between ports and are multi-tasking to reduce hardware costs.
