In the case of SNCP, the board selectively receives the service. Therefore, SNCP can protect services on the line.
If the overhead bytes pass through two plugged backplane buses, then the two slots are called paired slots that enable automatic transparent transfer of overhead bytes, such as (), () and (). Even if the SCC on the local network element The board is offline, which can also improve msP switching performance and protect DCC communication with other network elements. (Multi-quality selection).
