Last update 10 December 2011 An IP Profiling system is applied by Openreach on FTTC, running on the DSLAM in the cabinets. This sets the profile to about 88% of the connection speed. As there are no ATM overheads on the VDSL2 connection, speed test download speeds approaching the IP Profile can be expected unless the ISP’s system is traffic managed or congested. Bear in mind that speed testers using the Ookla system, such as speedtest.net and BBMax, usually report higher speeds than the BT Performance tester or the thinkbroadband tester. The only way to see your IP Profile on BT Wholesale based connections is by using the BT Performance Tester, see the New BT Wholesale page for more info and possible ISP problems. |
