Will VDSL2 affect the telephone conversation quality? Will making phone
2
calls cause a slow online rate?
VDSL2 separates voices from data through the frequency division multiplexing
technology. Therefore, voices and data run in different paths without mutual
interference. Neither the access rate nor conversation quality will fall even if you
are in a call and online simultaneously.
How to properly install telephone extensions or other devices on the VDSL2
3
line?
It is recommended to connect the VDSL2 splitter to the telephone cable first and
then connect the phone sets to the splitter interfaces. Installing a telephone
directly before the splitter will lead to connection failure between the ZXDSL
931DII and the device at central office side, or an Internet access failure, or a
slow connection speed. Connecting other electronic devices between the user end
and splitter may affect the VDSL2 communications (since VDSL2 has a higher
requirement for the line quality) and furthermore affect the normal operation of
VDSL2. If the phone sets are required to be connected before the splitter, you
should serially connect the MicroFilter before the phone sets (Generally, to
minimize interference, only one MicroFilter can be connected before the
splitter).
