3 Configuring SDH Services
3.10.3 Per-NE Configuration Process
The configuration of the services on the two-fiber bidirectional MSP ring with a non-protection
chain is independent of the creation of the protection subnets for the MSP and for the non-
protection chain. To configure the services on the two-fiber bidirectional MSP ring with a non-
protection chain, configure the SDH services from the tributary board to the line board on the
source and sink NEs and configure pass-through services on the intermediate NEs, if the
protection subnet is already created.
3.10.4 End-to-End Configuration Process
The configuration of services on a two-fiber bidirectional MSP ring with a non-protection chain
is independent of the creation of protection subnets for the MSP and for the non-protection chain.
To configure services on a two-fiber bidirectional MSP ring with a non-protection chain,
configure SDH services from the tributary board to the line board on the source and sink NEs
and configure pass-through services on the intermediate NEs, if the protection subnet has already
been created. The following part describes how to configure services on an MSP ring with a
non-protection chain in an end-to-end manner.
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.

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.
