Specifically in the UK, I'm trying to find out how the burst works that you experiance at the start of a download for a typical DSL service in the UK.
What determins the max speed you can burst to, available unused bandwidth at your exchnge; i.e. the link from the core to the DSLAM/MSAN you're connected to?
What device determins how long the burst is for before the rate limit kicks in, the DSLAM/MSAN? In the case of BT, the BRAS? The LAC?
How does this process/set up differ with LLU services compared to buying direct again with say, BT?
Many thanks to all for reading and any help you can provide
