AT&T uses BERT.....bit error rate testing and EVM.....Error Vector Magnitude testing...They also use QAM and QPSK Testing.... Quaduature Amplitude Modulation and QPSK.....Thats a verson of Shift keying testing..........And lastly they use your standard return path certification testing.....it's all great and you can use it anywhere.......most people don't....and it is a shame.
