Japan A/B plane insertion

Setting this configuration byte to 0x01 enables the HMRT component to operate in a Japan DDI network. It enables the proper insertion of the link set using the A/B plane bit for COA and CBA Message Signaling Units when connected to a STP pair using a common point code. Setting this byte to 0x01 should only be used in the Japan DDI network, but not in the Japan JT and Japan NTT networks. This byte has no effect in non-Japan networks.
