3.4.3 Per-NE Configuration Process
This topic describes how to configure the 1+1 linear MSP services.
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
3.4.2 Signal Flow and Timeslot
Procedure
Step 1
Configure SDH services on the source NE (NE1).
1.
In the NE Explorer, select NE1 and then choose
Configuration
>
SDH Service
Configuration
from the Function Tree.
2.
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
.
Parameter
Value in
This
Example
Description
Level
VC12
In this example, E1 services are configured. Hence,
Level
of the E1 services is set to
VC12
.
Direction
Bidirectiona
l
In this example, services are transmitted and received
over the same path. That is, the services are bidirectional
services. Hence,
Direction
of the services is set to
Bidirectional
.
Source Slot
3-SP3D
In this example, the SP3D board in slot 3 is configured
as the source tributary board for the bidirectional
services from NE1 to NE2. See
Source VC4

Source
Timeslot
Range(e.g.
1,3-6)
1-5
The total capacity of the service is 5xE1 according to the
plan. Hence,
Source Timeslot Range(e.g.1,3-6)
is set
to
1-5
.
Sink Slot
1-SL1D-1
(SDH-1)
In this example, the SL1D board in slot 1 is configured
as the sink line board. See
Sink VC4
VC4-1
In this example, the services require five VC-12s.
Sink
VC4
is set to
VC4-1
, because a VC-4 contains 63
VC-12s.
