INTER-CHIP PORT, AND METHOD FOR SUPPORTING HIGH RATE DATA STREAMS IN SDH AND SONET TRANSPORT NETWORKS

摘要

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 module comprising a group of chips; each of said chips (16) being capable of supporting a lower order SDH/ SONET signal with processing its TOH and POH, while one of them named a master chip being operative to solely process the POH of said high order concatenated signal and coordinate operation of the remaining chips named slaves so as to cause them to work in accord as one unit.
