3.10.1 Networking Diagram
In the case of the MSP ring with a non-protection chain, the networking diagram of the MSP
ring is similar to the networking diagram of the single two-fiber bidirectional MSP ring. The
only difference is that one line board needs to be configured on the intersecting NE when the
non-protection chain is added. This can realize the pass-through of the services when the services
are required to be transmitted out of the MSP ring.
shows the networking diagram of the MSP ring with a non-protection chain. The
MSP ring comprises five pieces of equipment. In this example, the SP3D boards are configured
on the source NE (NE3) and sink NE (NE5) as tributary boards to add and drop services, and
the SL4D and SL1D boards are used as line boards to transmit SDH services.
