Tributary Port

, and then click 

OK

.

3.

Configure NE5 using the method described in 

Step 4.2

.

4.

In 

Create SDH Trail

, click the 

SNCP Setting

Add

 from the shortcut menu. In the 

Add the dual-fed and selective-receiving node

 dialog

box that is displayed, select NE3 as the dual-fed node and NE4 as the selective receiving
node, and then click

3.10 Configuring Service on the MSP Ring with a Non-
Protection Chain

Configure the protection subnet for the MSP, Protection Subnet for the non-protection chain,
and services on the MSP ring with a non-protection chain separately. It is recommended that
you configure the protection subnets before configuring the services on the MSP ring with a
non-protection ring chain.

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.

3.10.2 Signal Flow and Timeslot Allocation

To configure the service on the MSP ring with a non-protection chain, you should plan a proper
traffic direction and a timeslot allocation scheme for the services on the SNCP ring and the
services on the non-protection chain.
