LLU : This is where an ISP has equipment in the exchange to enable them to provide ADSL completely seperate from BT's back bone network. They will only use BT's final copper pair of cable from exchange to house for their connection, and will use there own network from the exchange to the 'net' so to speak.
Other ISPs share the BT back bone network, and buy broadband access from BT at wholesale prices to resell to customers.
Most smaller exchanges still only have the BT back bone, and many only have a couple of LLU providers.
Your exchange shows as having TWO LLU providers, which is actually fairly good - mine has 1, and my surrounding exchanges have none.
Yours are :
O2 / Be: Enabled as of 30/04/2007 CPW / TalkTalk: Enabled as of 18/02/2008
I am not saying these are the best ISP's, but they will usually have the better connection in terms of speed and contention ratios. They will also not throttle speed nearly as much as BT wholesale have to. It all depends on how many people are dumped onto the connections.
As more and more LLU providers set up in exchanges, things should get better and better.
