Embodiment Construction
[0062] In the following embodiments, the control flag codeword is a special 10-bit K28.5 codeword as an example for illustration, and the processing methods for other types of control flag codewords are completely the same.
[0063] Since the special code word K28.5 of the control character in the FC frame is a 10-bit code word, the K28.5 code word must be converted into a special 8-bit code word, such as 0xab, in order to realize transparent transmission in the PSN network , the present invention provides following two processing methods:
[0064] method one:
[0065] The sender converts K28.5 in all FC frames (including ordinary FC frames, primitive sequences, and primitive signals) into special characters (such as 0xab), and the data field is still transmitted according to the original byte code. The format of SOF, EOF, primitive sequence and primitive signal encoded in this way is shown in Figure 6, including 8-bit special characters (such as 0xab) and 24-bit complete dat...
