NG-SDH product support to delete the 2FMSP parameter and again configure the parameter, even you have configured the services.
After above activity Site-B -10G becomes the extension sub-rack of OSN-7500.
So now we have to Delete the 2FMSP Groups at OSN-7500 and again configure it for 3-NE ring and Linear MSP b/w Site-B-10G and OSN-7500
Group-1-(2FMSP) for Three NE ring
Group-II-(1+1MSP) Connect with Optix 10G of Site-B
So above procedure you can check we can easily delete the MSP parameter in OSN-7500 and again configure it, the services only fluctuate for milli second.
We are task to perform the optimization of running SDH Network into DWDM.
a) First task is to commission the DWDM Network.
b) Then add OSN-7500 in existing SDH ring (connect with Optix 10G)
c) Connect the OSN-7500 to DWDM equipment
Site-A-10G---Site-B-10G-----Site-C-10G in a ring.
For working path
So after that we to perform the above activity for protection path.
So 2FMSP Group define has following way
Group-1 at OSN-7500
Group-II at OSN-7500
Group-III at OSN-7500
So now Network is configured Like below
Activity at protection path of Site-B (Activity purpose is bring Optix-10G is a extension sub-rack of OSN-7500)
Same procedure b/w Site-A and Site-B protection path and ring becomes
Now we have three NE rings
NG-SDH Feature to delete the MSP parameter and again configure it even the services is mapped , it is very useful for optimization of Network.
