<p>Disclosed are a method, device and system for realizing multichannel parallel interface adaptation. An OTU5 frame can be grouped by 12 bytes at the sending end, and the grouping cycle of the OTU5 frame is allocated to logic channels; and at the boundary of each frame, channel assignment requires rotation. As such, the frame alignment signal of each of the logic channels can be recovered from the receiving end and the channel flag involving rotation can be recovered, thereby eliminating the delay difference between channels and realizing regrouping of parallel channels. It can be seen that as compared to the prior art, the technology for realizing multichannel parallel interface adaptation in the present invention employs a 12-byte grouping solution, so that all the bytes of a frame can be allocated to logic channels equally, the channel rotation operation can be realized at the boundary of each frame, which greatly lowers the data processing complexity with respect to the 4-frame channel rotation operation solution in the prior art.</p> |
