ABSTRACT:
A SONET signal is terminated by pointer processing a physically concatenated SONET signal to output a pointer processed physically concatenated SONET signal. Virtual concatenation-related byte markers (for example, H4 and J1) are then inserted into the pointer processed physically concatenated SONET signal. Virtual concatenation overhead data (for example, MFI and SEQ#) is then inserted into the pointer processed physically concatenated SONET signal so as to produce a converted virtually concatenated SONET signal. Virtual concatenation logic processing is then performed on the converted virtually concatenated signal. In this way, a physically concatenated SONET signal can be received and processed on a single integrated circuit with a virtual concatenation logic processor receiver this obviating the need for including a separate physically concatenated logic processing receiver or multiple integrated circuit chips.
