The 1Mb service would be great - Central London only...
Thing is, I would be sceptical over the performance claims. Do Bulldog use their own DSLAMs ? If so, have they an STM-1 or STM-4 backhaul.
There is a 50:1 contention ratio...
So if it an STM-1 DSLAM = 155Mb/s backhaul (120 useable) / 4Mb/s = 30 Subscribers x 50 (contention) = 1500
Potentially 1500 people off a set of stacked DSLAMs (probably 3) over a 155 link.
Contention ratios pretty much rely on (in this example) 1 in 50 people using the service at any time....
It's the way all networks are built....(Only way to make it cost effective)..
If they have DSLAMs with STM-4 that would be OK...
