Abstract:
1. An integrated circuit for synchronous optical network or synchronous digital hierarchy or optical transport network (SONET) signal termination, comprising: virtual concatenation logic; an input for receiving either virtually concatenated or physically concatenated SONET signals; a pointer processor for receiving either of the SONET signals and outputs a pointer processed virtually concatenated SONET signal to the virtual concatenation logic and outputs a pointer processed physically concatenated SONET signal, wherein, in response to the SONET signals being a physically concatenated SONET signal, the pointer processor operates on the received physically concatenated SONET signal to identify synchronous transport signal (STS) locations within the pointer processed physically concatenated SONET signal; a virtual concatenation overhead insertion circuit for inserting virtual concatenation overhead data into the pointer processed physically concatenated SONET signal so as to produce a converted virtually concatenated SONET signal for output to the virtual concatenation logic.
