[AusNOG] NBN VDSL2 Filters

To answer the original question:

VDSL2 line filters are the same as good quality ADSL2 line filters. It's a
low-pass filter that lets only the lower voice frequencies (<300khz) pass,
and blocks out the higher xDSL frequencies.

Be aware that FTTN provides a stronger signal and greater cross talk than
most DSL users are familiar with. If you have a 2nd phone line, it may be
possible to inadvertently receive the FTTN signal through it - hilarity
ensues.
