I am retracting my previous comments about risk of crosstalk, in the past couple of weeks I have seen a few posts from people who have 2 lines in the same DP enabled and they insist they either have no or minimal crosstalk, so this changes the %'s a bit. Previously I had known 4 accounts of multiple lines in a DP which all had severe crosstalk now I know of 9 with the other 5 not having severe crosstalk.
Interesting comment Chrysalis. I'm sorted here at home now with a blend of Virgin and Plusnet FTTC.
Now work is a different thing.....
At my work we have a 20 pair coming onto site to a DP on the front of the building, in that 20 pair there is my new VDSL and an ADSL, which travel across the building roof in a drop wire to the same area. Also in that 20 pair is the companies head office (intranet) ADSL, 2 leased lines and 6 phone lines. The VDSL connection is great, clean and so far, faultless.
So I'm toying with the idea of converting the second ADSL to VDSL too. The 20 pair is around 80 metres from CPC10 to the outside of the building's DP, all the lines and the companies kit is within 5 meters of this DP. The VDSL and ADSL I'm on about is an additional 30 meter away down it's own drop wire across the roof.
I'm pulling 70/20 on the VDSL and 5/.8 on the ADSL....so changing the ADSL to VDSL would be a benefit, even if there is crosstalk. I'm back next week, will give BT business a call and see how much this extra change will cost me.
If nothing else, it may be an excellent opportunity for me to gather some info for us guys on the effects of 2 VDSL's on the same drop wire
