Hi,
I'm about to wire up a property for dual/bonded VDSL lines.  One will be naked and the other clothed.  I plan to install a master filter on the clothed line at the ETP.

I picked the location especially because it's close to the exchange so want to make sure that I do everything possible to maximise the line speeds.

Bearing in mind the line length from exchange is around 100 metres (Prequal came back with 1dB attenuation), I have two questions:

1. Will running two VDSL services down the same ~7m of Cat6 cable be a problem (ie: Should I run two Cat 6 cables from the ETP to my two modems)?

2. The lead in from the plastic pillar is ~18m of 4 core (2 pair) non twisted pair in a conduit. Chorus can replace it with 23AWG twisted pair cable for a small fee (around $200) - is this worthwhile?

edit: Changed "will replace" to "can replace"
