FTTC DLM Policy
« on: February 18, 2020, 11:17:14 AM »

How to tell if DLM policies for FTTC is on stable, standard or speed, seem can't find out. Does anyone know?

Also what is this Dynamic Line Management - 5 retrain DLM trial? - https://www.openreach.co.uk/orpg/home/updates/briefings/super-fastfibreaccessbriefings/super-fastfibreaccessbriefingsarticles/nga00520.do

Not sure about the policies, but that Openreach note looks like they are experimenting with adjusting the point at which a retrain is triggered (eg changing the number of ES that trigger a retrain, or perhaps using different parameters).
I don't suppose we'll be able to get the detail on this and will find out what they've done by looking at peoples stats over time.

Updated: PN has told me my line is on standard dlm policy and will placed an order to put me on speed dlm policy which it due to be completed tomorrow but has warned me that DLM can banded my line again if become unstable!

Does this mean will be 10 days training period as a DLM will be a new active on day 1 tomorrow?

I thought you had downgraded to 40/10 - on your line moving to the speed profile will make no difference whatsoever.

No I didn't as I stayed on 80/20 because if I downgraded to 40/10 I will be lots worsen on discount eg: 23.50 a month for 40/10 but 80/20 will remain at 22.50 a month.

It is fantastic to see that you took all the comments, including your own, on not fixating on broadband so much to heart.

It will be changing the MBTR thresholds.   
That is the number of times your line retrains (resyncs) before the DLM takes any action, which in turn depends upon what stability level the ISP uses.
