摘要： A method for communication includes, receiving in a first communication interface input frames, which include data symbols derived by encoding respective characters, and one or more synchronization symbols distinguishable from the data symbols. The characters are recovered from the data symbols, and transmitted to a second communication interface by mapping the characters into communication frames and discarding the synchronization symbols, wherein a protocol for delivering the characters supports a mapping scheme for delivering the characters at a first data rate, and mapping the characters includes mapping the characters so as to deliver the characters at a second data rate lower than the first data rate. The characters are extracted from the communication frames in the second communication interface by synchronizing to the mapped input frames independently of the synchronization symbols. The input frames are reconstructed to including the data symbols and the synchronization symbols, by re-encoding the extracted characters.

摘要： A method for passing communications over an Optical Transport Network (OTN) from a first communication interface to a second communication interface. The first interface extracts characters from received data symbols, maps the characters into OTN communication frames and discards the synchronization symbols. The mapping is performed using a Bit-synchronous Mapping Procedure (BMP), while filling some locations in the OTN frames with stuffing characters, so that the rate of the characters matches a desired rate of the OTN communication frames. The characters are extracted from the communication frames in the second communication interface by synchronizing to the mapped input frames independently of the synchronization symbols. The input frames are reconstructed to produce reconstructed input frames including the data symbols and the synchronization symbols, by re-encoding the extracted characters. In some embodiments, data from Ethernet frames is passed along with the extracted characters in the OTN frames.
