Re: Upload speed saga

There is/was a fault on the line and the DLM  has capped your speeds to be more stable by the look of things.

Engineers used to be able to clear this,  although most CP’s like to leave it and wait for the DLM to reset itself, usually after a couple of days.

(The old Cp trick was to just reset the DLM each time to resolve a slow speed issue without investigating what was causing it in the first place).

CP's have never been able to reset DLM on FTTC lines.

This is a few years old so who knows if it still operational, either way , no point really in resetting an unstable (faulty) line as it won’t be long before DLM intervenes again reduces the speed for stability as it did originally

FTTC reset of DLM in the beginning could only be  requsted by an Openreach engineer after resolution of a fault.

Note: engineers couldn't do it  by themselves they had to ring in and request it be done.

CP's have never been given the opportunity to reset DLM on FTTC connections themselves unlike ADSL. Thery can now request Openreach perform a reset but I would expect Openreach to remotely test the line first.

The big CP’s could as they were given the opportunity to do it about 8 years ago (same time they started sending their own “trained home engineers” out on faults), and Openreach engineers could do it with a call to 17070 platform, no need to call DCOE and request someone else do it for them.
