Hi pro
Could u pls give me some ideas in testing Alcatel TMA? How to check it and find problem on-site ?
I collected data from NPO system and found that TA_average in normal, high path balance, drop in UL, MS_Power high. But no alarm from BTS hardware. Parameters design are ok. Most of problem sites come from TMA installed.
Tks a lot

you should change TMS to TMB, TMA do'nt amplification uplink-> high path balace-> drop hight. you can tunning amplification downlink by refine button

Bypass it, and see if TMA causes problem or not, if CDR is the same, it's work nothing, if CDR is reduced, then check TMA, maybe it amplifies noise as well :D
