Fixed line plus is the new fixed line service on the new TUC networks architecture for Bangkok and upcountry area.
There are 104,457 subscriber as the end of year 2014 with average fault rate 0.87%.per month. If we do not any improvement will be have fault complaint to call center about 909 calls per month and will be increase when fixed line migration phase be started.
So, we have to reduce the fault rate to maintain the customer satisfaction and reduce the O&M cost.
