Claim:
1. A method for communication, comprising: receiving in a first communication interface input frames of Common Public Radio Interface (CPRI) signals from multiple CPRI sources, wherein the input frames comprise data symbols that were derived by encoding respective characters, and further comprise one or more synchronization symbols having no corresponding characters; recovering the characters from the data symbols, and transmitting the recovered characters to a second communication interface by mapping the characters into communication frames and discarding the synchronization symbols, wherein mapping the characters comprises interleaving the recovered characters using a predefined interleaving scheme that alternates among the multiple CPRI sources; extracting the characters from the communication frames in the second communication interface by synchronizing to the input frames independently of the synchronization symbols; and reconstructing the input frames in the second communication interface, including the data symbols and the synchronization symbols, by re-encoding the extracted characters.
