3.6.3 Per-NE Configuration Process
This topic describes how to configure the two-fiber unidirectional MSP service.
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
l
You must be familiar with the information about
3.6.2 Signal Flow and Timeslot
Procedure
Step 1
Configure unidirectional services from NE1 to NE3.
1.
Configure SDH services on the source NE (NE1).
l
In the NE Explorer, select NE1 and then choose
Configuration
>
SDH Service
Configuration
from the Function Tree.
l
Click
Create
on the lower-right pane to display the
Create SDH Service
dialog box.
Set the parameters that are required, and then click
OK
