Your ISP is talking rubbish.
The BT Wholesale DLM (Dynamic Line Management) can be set to Auto
, that being a setting the ISP can select. Normally at initial setup time. IIRC it can also be set to Fast Path, but in severe problem cases it will still switch to Interleaved.
Once it is set, or switches to, interleaved it never automatically switches back to Fast Path.
You say your ISP is now part of TalkTalk Business. Is TalkTalk present at your exchange? Samknows
is the best place to check, using your phone number. If you post the URL of the result that would be best for us.
Does this checker
recognise your phone number, and is so what does it say please?
Finally, does the BT Performance Checker
work for you? If it does, can you continue from the initial results to the Further Diagnostics
near the bottom of the page. Then copy and paste the contents of the two results text boxes
The above will confirm whether you are still on a BT Wholesale service in the first place, and give us useful diagnostics if you are.
