2.6.4 Creating a Linear MS Protection Subnet
In a chain network, an NE can protect the services in different fiber sections after a linear MS
protection subnet is created.
Prerequisite
l
You must be an NM user with "NE maintainer" authority or higher.
l
The NE data must be configured and fibers must be created properly.
Precautions
CAUTION
l
Starting the protocol controller may interrupt the services.
l
Fibers that are used for the linear MSP cannot be used by other protection subnets. That is,
a linear MS protection subnet and other subnets cannot be used together to form virtual fibers.
Procedure
Step 1
Choose
Service
>
SDH Protection Subnet
>
Create 1+1 linear MSP
from the Main Menu.
Then, the
Create Protection Subnet
window is displayed.
NOTE
To create the M:N linear MS protection, choose
Service
>
SDH Protection Subnet
>
Create M:N Linear
MSP
from the Main Menu. Then, the corresponding window is displayed.
In the case of the M:N linear MS protection scheme, set the number of working links to
N
.
M
indicates the
number of protection links and cannot be set manually. Currently, the value of
M
can be 1 only.
Step 2
Enter the name of the protection subnet.
Generally, the default name is used, for example, 1+1_MSP_1.
Step 3
Select the capacity level of the protection subnet, for example, STM-4.
