3.9.3 Per-NE Configuration Process
Before you configure the services on the SNCP ring with a non-protection chain, familiarize
yourself with the information about the source slot, sink slot, and their corresponding timeslots
of the working service and protection service on the source and sink NEs on the SNCP ring. You
need to configure the pass-through services on the intersecting NE.
Prerequisite
l
The physical topology of the network must be created.
l
The NEs, boards, and fibers must be created on the U2000.
l
The created protection subnet must be consistent with the actual network topology. For
details about how to create the protection subnet, see
2.6.1 Configuring a Non-Protection
l
You must be familiar with
3.9.2 Signal Flow and Timeslot Allocation
.
Procedure
Step 1
Configure the SDH services of the source NE (NE3).
1.
In the NE Explorer, select NE3, and then choose
Configuration
>
SDH Service
Configuration
from the Function Tree.
2.
Click
Create SNCP Service
on the lower-right pane to display the
Create SNCP
Service
dialog box. Set the parameters that are required, and then click
OK
.
