you only need to configure the selective receiving service in actual service configuration. That
is, if the SNCP service pair is configured, the service configuration of the SNCP is complete.
3.2 Configuring Services on the Non-Protection Chain
Configure the protection subnet and the services on the non-protection chain separately. It is
recommended that you configure the protection subnet before configuring the services on the
non-protection chain.

3.2.1 Networking Diagram
You can configure a non-protection chain if the services on the chain need not be protected. In
this case, all the timeslots on the chain can carry services.
shows a point-to-point non-protection chain. In this example, the SP3D boards are
configured on the source NE (NE1) and the sink NE (NE2) as tributary boards to add and drop
services, and the SL1D boards are used as line boards to transmit SDH services.
