Interconnection between LW40 and LU40 (40G OTU boards)

The UFEC modules in the LW40 and LU40 boards are provided by different vendors. As a result, the UFEC algorithms of the two boards are different and therefore the two boards cannot be interconnected.
To implement interconnection between LW40 and LU40 boards, disable the UFEC function of the two boards and enable the standard FEC function of the OTN equipment. The FEC error correction capability, however, will be greatly reduced when the standard FEC function of OTN equipment is used.
