the reason i ask is that in our bts installations we do see a variety of levels received from telco. usually close to a 0 dBm(or -20 dBdsx)however at times they arrive 7 dB or so down from that. Still within tarrif requirements. I want to know how low a rx level i can accept before i need to regen.(add a csu. in some cases our bts’s are not colocated with the telco demarc. i understand the rules for lbo for tx back into the netwrok, but i would like to understand how much loss i can have from the niu to the bts and still be able to function.
