having two vdsl providers, what happens?

im with sky atm and get a max attainable of 71, connected at 71.

if i was to get another isp installed with a new phoneline and was to opt for another 80/20 package, would i get the same speed as i do with sky?

ive always wondered if the first connection would impact the second, then again its a totally different port in the cab, i think?

Cross talk is a possibility, and its a case of until you try you won't know

As for will 2nd line perform the same all depends on the route it takes to the cabinet, likely to be the same but not guaranteed

i wasnt planning on doing it, but if i ever feel like i want to, i thought it would be best to ask, i mean im paying £47 a month for sky.

if i was to get another provider probably be talk talk as theyre cheap.

also the contention the service provider offs as they might not be on the same contention ratio so one line many have a better performance than the other

contention ratio became irrelevant a long time ago, certainly it should not be used as a measure of performance nowadays.

It's likely to be within a few Mbps.

At my old house I had one line at ~43/7 and one at ~46/6.

I didn't notice any slowdown when the second line went live.

The old days of the 20:1 and 50:1 contention ratios on ADSL at exchange level are no longer relevant, but there is still contention beyond the exchanges at a regional and national level.

The condition of the line comes into play as well. At my last place there was 120m of aluminium cable with dodgy copper/aluminium joints in the mix and my line with Sky synced at 54 Mbps and my work line synced at 26 Mbps.
