Note:
Noise Margin is the non-technical term for Signal to Noise Ratio Margin (SNRM). Domestic standard modems and VDSL2 routers
often use the terms Noise Margin or SNR when reporting on its value. The Signal to Noise Ratio, as its name implies, is the ratio
between the strength of the signal and the level of noise on the line.
That ratio is a major factor in determining the connection speed, as the higher the ratio the higher the possible speed. The SNRM is a
margin which by which the noise level can rise before connection is lost.
Taking the default (target) value of 6 dB applied is follow up telecom standard. Basically, you don't need adjust this value.
