Just tried the checker for my number and it says (edited)

ADSL broadband service that provides a fixed line speed up to 2Mbps.
....
ADSL Max broadband line speed of 4Mbps; typically the line speed would range between 3Mbps and 7Mbps.
....
an estimated ADSL2+ broadband line speed of 5.5Mbps; typically the line speed would range between 3Mbps and 8Mbps
....
an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 3Mbps; typically the downstream speed would range between 2Mbps and 4Mbps.
....
an estimated WBC FTTC Broadband where consumers have received downstream line speed of 7.7Mbps and upstream line speed of 3.3Mbps.

I am on an LLU line for broadband and receive a consistent 5Mbps download and 550-560Kbps upload. So fibre doesn't give me all that much (I'm not concerned too much about upload speed). The only cabinet I've seen in the area is about 1/2 mile crow flies distance.

By comparison the BT Infinity checker says

BT Infinity is not currently due to be rolled out in your area.Register and we will keep you up to date about the BT Infinity rollout.

So I don't see any benefit in considering FTTC.

In reply to a post by RobertoS:

Well he does seem to be a BT FTTC engineer?

I see no indication of that. I was just puzzled by what units he was implying for his quantities.

And I was merely answering your question which seemed to doubt that anyone could have seen that many installations.

Hi,

I work for BT so hopefully can help! I've had my BT Infinity installed at home today. I was on the original ADSL getting 2.5Mb. My new BT Infinity speed is 37.8Mb Download with 10Mb upload.

The reason you reqiure a BT Line is because it is FTTC (Fibre to the Cabinet) from the Green cabinet nearest to your house it remains copper (so customers do not need new cabling into their house).

The www.bt.com/infinity can tell you by your landline number what speed you can get and when it will be available in your area.

My view very good. Amazing for downloading music, can stream live 1080p HD Movies and is awesome for online gaming. Very good buy!

I have just followed that link to confirm that I can't get the service, however when I try and find out, the site reckons my phone number and post code down match. Err, yes they do. I suspect it is because I only have a 6 alphanumeric postcode, I have had that problem on poorly produced sites before .....?
