EFFICIENT MAPPING OF CPRI SIGNALS FOR SENDING OVER OPTICAL NETWORKS
First Claim
1. A method for communication, comprising:
- receiving in a first communication interface input frames, which 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;
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.

Abstract
A method for communication includes receiving in a first communication interface input frames, which include data symbols that were derived by encoding respective characters, and further include one or more synchronization symbols having no corresponding characters. The characters from the data symbols are recovered, and the recovered characters are transmitted to a second communication interface by mapping the characters into communication frames and discarding the synchronization symbols. The characters are extracted from the communication frames in the second communication interface by synchronizing to the input frames independently of the synchronization symbols. The input frames are reconstructed in the second communication interface, including the data symbols and the synchronization symbols, by re-encoding the extracted characters.

12. An apparatus for communication, comprising:
-
a first communication interface, which is configured to receive input frames that comprise data symbols derived by encoding respective characters and that further comprise one or more synchronization symbols having no corresponding characters, to recover the characters from the data symbols, and to transmit the recovered characters by mapping the characters into communication frames and discarding the synchronization symbols; and a second communication interface, which is configured to receive the communication frames from the first communication interface, to extract the characters from the communication frames by synchronizing to the input frames independently of the synchronization symbols, and to reconstruct the input frames, including the data symbols and the synchronization symbols, by re-encoding the extracted characters. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
