Dear All
In our network we use Huawei BTS 3900A and lastly, we start the use 1800 and 900 board in the same BTS and we meet a problem with the call quality. (white call)
PS: - We observe that for some site, the FER was high.
- some site use 2 E1.
1) Is there anyone who have this problem in their network and what was the real cause?
2) from which value we can judge that the FER is High.
Thanks for your help.
