EXTERNAL CLOCK REFERENCE PROBLEM

Please I need help on how to clear external clock reference alarm on TDM and IP clock failure on IP site for 2G sites

SET BTSIPCLKPARA: IDTYPE=BYID, BTSID=94, CLKPRTTYPE=PTP, CLKTOPOMODE=PTPOVERUDP, ISCLKREDUCY=UNSUPPORT, MASTERIPADDR="xxx.xxx.xxx.xxx";
with xxx is your ip clock server

you must check the frequency deviation by DSP CLKTST:SN=7; make sure all is locked not Free Running

Dear if all are not lock then what to do...?????????

you need to check on U2000 for clocking connection & Quality
if those are good, you have to "tune" the Center DA by add/reduce until deviatioin is around -11dB.
to get clock calculation :
A : (Freq Discremination/1000)*1667
B : A (+/-) Current DA

Note : (+) for -A and (-) for +A
B : Center DA
