Q6: What is SNR and what’s the effect?
A6: In analog and digital communications, Signal-to-Noise Ratio, often
written SNR, is a measure of signal strength relative to back-
ground noise. The ratio is usually measured in decibels (dB).
In digital communications, the SNR will probably cause a reduction
in data speed because of frequent errors that require the source
(transmitting) computer or terminal to resend some packets of
data. SNR measures the quality of a transmission channel over a
network channel. The greater the ratio, the easier it is to identify
and subsequently isolate and eliminate the source of noise.
Generally speaking, the higher SNR value gets better line quality,
but lower performance.
Q7: What is band plan and what’s the effect?
A7: VDSL2 defines multiple band plans and configuration modes
(profiles) to allow asymmetric and symmetric services in the same
binder (by designated frequency bands) for the transmission of
upstream and downstream signals. User has the ability to select
fixed band plan. When Symmetric is selected that provides better
downstream performance, when Asymmetric is selected that
provides better upstream performance.
