Having checked my postcode on thinkbroad's map against the closest telephone exchange (straight line distance about 500meters) I was hopeful of fast speeds on ADSL. When the connection went live I connected locally into the Sky phase 3 router (Sagem) via a web browser using the internal IP of 192.168.0.1 . On the maintenance page you will find a show statistics button at the bottom which gave me the following:
Here I could see the downstream attenuation which I could put into a attenuation calculator to see if I was near the theoretical maximum. 21,344kbps was suggested as the absolute maximum so I wasn't massively off.
It's likely that I could improve on my downstream sync speed of 17.7Mbps with a couple of tweaks such as going directly to the master socket's test socket, removing other devices from the line such as the phone and trying a different DSL filter / shorter data cable.
Next up was to try some speed testers which test throughput (Note the sync is the connection to the telephone exchange, throughput is what is passing through that connection and is effected by anything else that maybe using the connection at the same time as the test).
The results were not bad either, 14Mbps during the day is very decent. I'll take some evening reading as well to update the blog but I'm very happy for the time being. FTTC is in my area but I can't really justify the cost with these speeds having some from a long line where I had a sync of 4Mbps. It's a shame Sky don't offer static IP's but at least they have put dynDNS.org functionality into there routers which I'm told is a lot of hassel on Virgin Media who I almost had to sign up to.
Here's hoping for IPv6 functionality as well.
EDIT:
An evening speedtest result around 9pm
