I looked for BT documentation on this a couple of years ago and could no longer find it
. It used to be readily available, so either I was looking in the wrong place or it's another thing they have either scrapped or no longer wish the public to know. If t is still the same, ISPs will of course know.
As I remember it there were three stages.
Stage 1 is what we all use.
Stage 2 the ISP had an option to set it up to route differently within their own routers, or more directly from them to the BT test server.
Stage 3 went from the BRAS to the test server and never touched the ISP's systems.
