I am using UCM6510. I am located in India. I am using 30 line Digital PRI line from Airtel company in India.
When I am trying to configure E1 based on MFC R2, I can see different options like ITU for International standards and some country specific options like China, Mexico etc.
But there is no option for India. Unfortunately it does not even specify where I can download relevant files to install for India specific MFC R2.
