Abstract
A method is provided for selectively inserting data, from a plurality of data sources, into a transmitted stream of information. The method makes a first selection to store data from at least a first and second source in a TX_OH memory. Then, the method makes a second selection, inserting the data stored in the TX_OH memory, into a transmitted stream of information. Typically, the information stream is a SONET/SDH protocol communication in a frame structure which includes overhead bytes. The provided method permits the overhead bytes of a received SONET/SDH communication to be selectively replaced with overhead bytes from either an FPGA or microprocessor source. An apparatus and system for arbitrating between multiple data sources in a communication transmission is also provided.
