DLM ES per day
« on: July 01, 2017, 11:42:03 PM »

Anyone got a link or can tell me the limits per day for DLM ES DS on the various profiles that MWDS features such as Standard, Speed and Stable?

They are tabulated on the DLM popup gadget on MDWS.....

Are you mad lol? How on earth can the ES figures shown in MTBE format be clearer than the MDWS popup?

The "per day" limits you asked for aren't shown on Kitz DLM page for FTTC. The coloured table labelled "Standard DLM Algorithm for line categorisation" is for ADSL DLM only.

The traffic light popup on MDWS uses the MTBE figures from Kitz DLM page and gives daily ES limits. It can be difficult to understand at 1st though. Once explained the popup makes much more sense, or did to me.

Speed Profile
1 - 288 ES per day = Green
288 - 2880 ES per day = Amber (no DLM action)
2880 - 86400 ES per day = Red (DLM takes action)

86400 would be 1 ES for every second of the day, so unlikely.

Standard Profile
1 - 144 ES per day = Green
144 - 1440 ES per day = Amber (no DLM action)
1440 - 86400 ES per day = Red (DLM takes action)

I don't know any residential ISP's who use the Stable Profile.

Things are complicated even further by BT OpenReach and BT Wholesale naming the DLM  profiles differently, but confusingly similar. I always use the OpenReach naming, as does Kitz, as does MDWS.

BT OpenReach - BT Wholesale
Speed           -       Standard
Standard      -       Stable
Stable           -       Super Stable

edit: lots of edits later, added more info

Have kind of forgotten the formula but I do remember this there are 86400 seconds in 24 hours so if you had 10 ES in 24 hours 86400/10 = MTBE 8640

I see "Pop-up Not available in Original mode" on MWDS. But thanks for more info John.

Anyone know how DLM implements capping? Is it retrains or errors or both. Conscious of swapping modems too much.

I also think DLM has changed as I was getting 3dB SNRM at one stage which gave me Amber on MWDS but DLM took action anyway and knocked me back to 4dB and currently on 5dB probably due to re-syncs.

It uses both MTBE (errored seconds) and MTBR (retrains) they are independent of each other while MTBE may switch off fastpath to interleaving MTBR can cause the capping that your interested in by lowering the sync rate until it has seen a period of stability.

Any idea what the MTBR is for capping?

Your full of questions to-night i'll take a guess 20 retrains for Speed and 10 for Standard and 5 for Stable.

As long as you know your Broadband limitations and stay within it and can act fast to keep it that way if things go wrong you will enjoy yourself  :)

The "per day" limits you asked for aren't shown on Kitz DLM page for FTTC.

DLM uses MTBE rather than 'x'  per day, so you also need to take uptime into consideration.   
The DLM calculator will convert Errors and Uptime to MTBE.
