Sub 6dB Target SNRM Announced
« on: March 17, 2017, 07:40:14 AM »

DLM profiles with lower target margins go national on Monday 20 March

Last year, to improve line speed for our end customers’ we started a trial on 40k active lines. The great news is that a percentage of these selected FTTC circuits saw the dB margin reduce from 6dB to as low as 3dB so this selection process will become national in a phased roll out.

I'm afraid this is the quote (minus the piece to engineers about resets) in its entirety, Chrys. No mention of Huw and/or ECI amongst it.  :-\

I'd also be interested to know if us ECI users are also getting these new profiles.

wasn't the general feeling ECI would need to see G.INP first before the lower profiles. I know that on the recent trial on those southwest cabs it stated ECI cabs were excluded...

here's hoping perhaps we might get G.INP back soon - wishful thinking   :-\

yeap on it goes..... eci users losing out again.. :no:.

"openreach has confirmed to ISPreview.co.uk that the roll-out is still due to commence this month as planned (phased roll-out) and some updated performance data from their extended trial is due to be shared with ISPs over the next couple of weeks.

We also asked whether ECI based VDSL2 DSLAMS (Street Cabinets) would continue to be excluded from the roll-out (as first reported here) and they confirmed that the enhancement will only be applied to Huawei based DSLAMS. ECI kit has become notorious for causing problems with various VDSL2 enhancements and changes.

Remember, not everybody will benefit from the new SNR profiles and Openreach’s DLM technology won’t apply the lower margin(s) unless your line is deemed likely to benefit"

No surprises there really,  all I need to know is when our second cab is live.

It'll be interesting to see this in action with circuits who have variable SNRM's you know the type the ones that swings by + or - 1dB during 24 hours, without knowing what safety measures have been put in place in the DLM then good long stats are required.

Have only monitored one such circuit on MDWS that had a swinging SNRM and to me it looked very erratic or the person in question had broadband/telephone line problems.

Was looking for you on MDWS and now see your username, I'm sorry but can't understand what is going on with your previous 4 days of SNRM it's erratic  :yuck:

Looking carefully it does not look like your line is on this sub 6dB SNRM trial

Had a resync at 00:24 today. Have an extra couple of megabits.

Not sure what to do with it all. My life is now complete and I can die happy. I'm nearly up to 2/3rds the download speed I had 6 years ago.

I think it must be after after the sync early this morning. I'm on Infinity 1 so have some headroom.
