Is this DLM checker still relevant?
« on: February 04, 2015, 11:18:32 PM »

Hi all,

I found this page on kitz site: http://www.kitz.co.uk/adsl/DLM_calculator.php

I've been using it to compare my error seconds over a 24 hour period (I've noticed that it only likes to do up to 24 hours). Is the formula still correct for todays FTTC lines?

I'm just asking as it does seem to give a good idea of how many ES's are allowed her 24 hours (it seems to be 72).

P.S.

Not sure if I posted this in the right area or not  :-\

Kitz created this calculator a while ago, but as far as I know its still relevant :)

Most FTTC lines will be on the Standard profile - depending on the ISP. Anything over 143 ES over 24 hours puts the line in "Amber", which means that DLM won't make a positive change, but keeps it as is. A Green status means a positive change can be made.

Over 71 ES would cause amber for the Stable profile, I'm not aware of any ISP that uses the Stable profile.

Ok thanks mate. Yea I've noticed the highest error seconds I've got on download over 24 hours as been 28. I'm interleaved on download but I'm at 62mb's, up from 57mb when I changed to the HG612. So maybe it might go higher. I've noticed my SNR Margin is much more stable these days too.

Anyways, I'm glad its still relevant as I've been using it to check the error seconds stats :)

It's good to have a place were people are knowledgable about these things.

Yep AFAIK it was correct... at least up until the ASSIA case late last year and uses the last known figures that were publicly available from BT.
 
Since then though they have been fiddling with some things.  I doubt it would be the MTBE or MTBR, but the caveat is there that since said court case theyve kept very tight lipped about certain things :/



The only ISPs that have outright said which profiles they use are
Speed: Plusnet, Zen and probably AAISP
Standard: Is the default profile and thanks to jid we know that TT definitely use this.

BT is a bit fuzzy.  Supposedly Standard, but seen rumours on their own forums that this can be changed by EU request.

Thanks kitz,

I wonder if there will ever be a day BT will open up about the technology used? Why is their so much secrecy.

Probably because there are certain telco's who are in competition and would like to know certain info. 
Also legal implications such as the recent court case.

TBH, although it may not seem like it to us and it can be frustrating at times to find out info... they are far more open about their network than many of the other telcos or transit providers.

Alot of BT is secrecy which I find annoying, e.g. exchange outages, svlan status etc. is only available to BTw customers.
