I have Max but low speeds or What about this 10 day setteling time?
The biggest complaint (or at least the one people are making the most noise about) is the issue of people now seeing high line sync speeds, but the actual download speeds are very low in comparison. We have previously talked about the BRAS Data Rate, and how BT Wholesale use this to control the throughput on a connection. What many may not be aware of is how this Data Rate varies over time. Contrary to rumour, the BRAS Data Rate is not set to a fixed value after the 10 day ‘training’ period, it can vary at any time. The rules are such that if you line resyncs at a line speed lower than previously, the rate will drop automatically, and for it to rise again you need to see three days of higher line sync speeds. For example, if you sync at 5120kbps you will normally have a Data Rate of 4.5Mbps, but if the line speed drops to 1728kbps your data rate will drop to 1.5Mbps immediately, only increasing once a sync speed of 2272kbps or higher is seen for three days.
