IN BTS -48V IS USED REASON BEHIND IT IS THAT
When
interference is occur in voltages it affect only positive
pulse not in negative terminal so if we make positive
common then no interference occur And we get pure -48 volts
without any interference.
Another reason is that
we can use +48 but the lightning has -ve charge due to attraction all the network may destroy so we use the -48 which repel the lightning that make the network safer from great destruction...
