In our network the maximum configuration we use is only 7+7+7 (4+4+4 in 900 and 3+3+3 in 1800). Is it possible to increase the configuration. Or why is the configurations confined to just 7+7+7.
It proves the configuration is not confined… it is certainly just a choice based on capacity and traffic. Check with your design team why they didn’t use 8/8/8.
