As shown in the figure, the PW path is established between the tributary boards (users connect to customer equipment) at two sites, and the tunnel path is established between the line boards (used to connect optical fibers) at two sites. In a site, the PW path between the line board and the tributary board does not need to be encapsulated in a tunnel. |

The line board is the board that communicates with the peer site. The optical fiber or cable connected to its port is from the peer site. A tributary board is a board that provides channel ports with the local client equipment. The optical fiber or cable connected to the port is from the local customer equipment.
