Thanks carry for your valuable clarification:
Further more we till facing this problem in our net work(error in connection).& we already perform some investigation: such like Redimensioning the Air interface,new roubst plan for our freq,optimization for LA,BTSs config, …..& so on(all major in our side (radio planning)).
So I think you are right, Cuz we have two link system, PDH & LMDS as backbone & our TX planners are quite new in LMDS technology.
But regarding the troubleshooting, what is the efficient way to trace it,is it recommisioning our links(& what Abis or Ater) or it related with MSC performance or what…. Plz i need more clarification on it(Document if available).
OUR VENDOR IS ALCATEL
thanks
