Apologies if this turns out to be a slightly longer post but I hope there is enough experience out there with FTTC lines to help me with this.
I currently have two BT lines and now my exchange is about to be FTTC enabled, am likely to get FTTC on one line and cancel the other.
The question is which line should I get FTTC on and/or does will it make any difference to the speed/performance I will actually get (i.e. how much does expected ADSL performance affect expected VDSL - I know one is from the cabinet and the other is from the exchange but still..)
I'm about 3.5km from the exchange and approximately 500 metres from the cabinet.
Some background on my 2 lines.
Line one currently has o2 llu broadband on it and typically syncs at 5.8-6 Mbps.
The BT checker for the line states 'your line currently supports an estimated ADSL2+ broadband line speed of 6Mbps; typically the line speed would range between 5Mbps and 7Mbps.'
When I first got 2Mbps ADSL in 1999 the line only just made it under the original 41db limit
Line two doesn't have ADSL on it now, but when it did found qualifying for 2Mbps easier.
This is illustrated by the BT checker for line 2 stating "your line currently supports an estimated ADSL2+ broadband line speed of 7.5Mbps; typically the line speed would range between 6.5Mbps and 8.5Mbps.
For both lines, the VDSL estimate is the same at around 28mb
So the question is which should I get FTTC on and will it make much difference?
Line one has been 'active' for over 30 years and line 2 for 12 years+ but the drop wire for both is the same - having been replaced when line 2 was put in. I haven't had a BT fault for quite a while but when I used too, it was always on line 1 and a problem 'between my house and the exchange'
The above seems to suggest line 2 would be the better choice but line one is my main number (and subject to a 12 month BT rolling contract).
How difficult would it be to transfer that account/telephone number to line two and (eventually) cancel the existing line 2 account? - perhaps moving that to line 1 on a temporary basis to keep my o2 account until FTTC is active?
Also, does anyone know how much difference this might actually make in terms of maximum sync speed, especially with things like vectoring coming down the road..
