Oh WOW!


[link to this post]
 
There was me drafting a post, went to Preview at about 00:28 and after a bit of faffing saw I had lost internet connection.

Came back up with down and up SNRM at approx. 5dB and hugely improved sync's.

Current 68233/15526Kbps, previous 65702/13958Kbps established only a day or so ago.

HappyBunny on MDWS if anyone wants to take a look.

My stats (tenbyboy2 on MDWS) )are very similar to your's so hopefully I'll see a similar speed increase when the SNRM changes kick in for me!!

I seem to have the same oddity I was getting up until a few days ago when I accidentally caused a couple of re-syncs. A slight creep upwards on downstream SNRM overnight. Went down again at dawn. With a very slow rise in the underlying one. That went on for a long time, with the upstream doing the same.

Attainable is bang on unchanged. There is definitely some static setting being used for that calculation.

There was no area power cut! I had several lights on in the room with one not far above my head. Not a flicker, never mind a noticeable cut.

68meg at 600m is mighty impressive.

I agree but isnt it a bit sad that in this day in age that 68Mb at 600m is considered so impressive!

It's still more than adequate for the vast majority of households, so no, not sad really.

Looks like a DSLAM reset to me. The upstream should remain on a 6dB target. The fact it has also dropped to 5dB suggests it's not a DLM thing. The attainable WILL rise with a lower SNRM target, certainly with any Broadcom modem.

A resync is the easiest way to find out. The lower dB DLM profiles remain in place after a resync. I'm pretty confident the line would resync at 6dB.

To paraphrase an estate agent: Gauge, Gauge, Gauge.

Attenuation is 19dB, which is exceedingly low for 600m. I suspect some fat cable might be being used... possibly even 0.9mm copper.

In comparison, my second line had an attenuation of around 16dB, and was approx 375m from the cabinet. That was quite good performance for the distance, and I occasionally wondered whether that was fatter than the standard 0.5mm

My third, current line has an attenuation of 8.5dB, but is only 100m. I strongly suspect that this is thinner (0.4mm) copper though. If so, it would act like 150m of standard 0.5mm copper.
