7. FAQs

Q1: What is voltage of the VC-231/VC-234?
A1: 5V DC, 2A
Q2: What is VDSL2?
A2: VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2),
G.993.2 is the newest and most advanced standard of
xDSL broadband wire line communications.
Designed to support the wide deployment of Triple Play
services such as voice, data, high definition television
(HDTV) and interactive gaming, VDSL2 enable operators

G.993.2 VDSL2, but with different Profiles, so far they are
not compatible with each other.
Q6: What is SNR and what's the effect?
A6: In analog and digital communications, Signal-to-Noise
Ratio, often abbreviated as SNR, is a measure of signal
strength relative to background 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
