In a IBS site RBS 2111v2 is running. from past 4-5 days we have observed that combined output signal of 2 RRUs are fluctuating alot(tested by directly connecting an antenna to rru o/p).
signal is fluctuating from -12 to -30 while making calls.
when 1 rru is kept in local mode. signal is stable, same in reverse versa.
Uncombined output of both RRUs are OK.
We have found no E1 slip errors.
TCH drop is increased alot..
