yes dear, it’s possible
the basic funda is u have ip connectivity of any of the equipment u want to put in network. So for Nsn bsc u should know ur bsc’s IP, if u dun know then no problem u have to just put a command ZQRI and u now u know the logged bsc’s IP. Now for logging in to ur bsc through ur IP u should configure ur lan adaptor, connect lan cable to ur pc and another end toMCMU’s port and telnet that IP and u’ll be logged on.
Now u r ready to put ur system on ur own network (that may be internet). U can now connect this to switch to ur own gateway or host. And u can connect ur bsc from ur site using internet.
