Inter-chip port and method for supporting high rate data streams in SDH and SONET transport networks

摘要

A method and an inter-chip communication port for supporting a concatenated type of a high order SDH/SONET signal, with processing Transport Overhead bytes (TOH) and Path Overhead bytes (POH) thereof, in a structure which comprises a group of chips, wherein each of the chips is capable of supporting a lower order SDH/SONET signal with processing its TOH and POH, while one of them named a master chip is operative to coordinate operation of the remaining chips named slaves so as to cause them working in accord as one unit. <IMAGE>
