Wow, what happened here?!

 

 

I thought I was on an Ikanos card, that's why it was limited to 70/30?

 

 

 

 

 

 

From the stats clearly you are on a Broadcom card and not an Ikanos card. Perhaps a swap at the cabinet level happened sometime.

That's what I thought too but I wasn't 100% sure.

Anyway, it was a surprise to me as I wasn't expecting them to upgrade the card.

The capabilities of VDSL continues to amaze me.

Are you basically living in a tent right next to the cabinet?

No, I'm actually about ~200m give or take a few.

Port changes are a common habit for chorus techs to do while fixing a fault when they suspect it is the port or don't really know what else it could be.

 

 

 

In this case, possibly what happened is a customer on a broadcom line was switched with you...

 

Your RSP should be able to indicate if your physical port number has changed (although Tier one may not know what your asking)

 

 

 

If it is still an ikanos linecard, Very interesting.

200m. You must have a very clean line (within little to no crosstalk) right from the cabinet right through to your modem. Very impressive.

Hey guys, I've been keeping an eye on my speeds with the recent changes.

 

We went from 13.5/1.0 to 13.5/1.2 when the change happened to our up load (6db) then went to 16/1 when the download when to 6db (upload went back to 12db)

 

but now our speeds are way lower than before? no changes made? I've turned off the router and given it 20mins etc, any ideas?

Could be a line fault.

 

 

 

on the basis that your line has pulled back to 12dB and then to 16dB (Stability profile)

 

 

 

I'd suspect modem based on it looking like one of the old Dlinks...

This might just be ddDLM doing its job. There is no white paper on how ddDLM actually work. My own experience is since ddDLM went live on the line at the end of April. My down sync speed has fluctuated from 45 MBps through to 68 Mbps. ddDLM went round in circle a few times testing the both the upper and lower boundary limits for sync speed. In the last week or so it seems to have settled at around 65 Mpbs mark for down and 22 Mbps mark for up.

 


If my experience is typical (no one would know except Chorus Engineer) then your fluctuation could be just ddDLM doing its job. In any case I would not recommend rebooting modem as that is most likely counterproductive and can confuse ddDLM. Leave it for a couple of months and see where it lands. I know it is unnerving but patient might be the best course of action here.

Thanks to both of you, It is an older modem (belkin n300 estimated 6+ years old) I don't need anything flash, just a few lan ports and N wireless (for mobile phones) any recommendations on models? (I live rurally if that helps narrow it down) as it would be worth upgrading. But yes I might give it til the end of the month.

Ask your ISP for something is the easiest way. That way they cant go blaming it for problems.

exciting day today for ddDLM.

 

 

Woke up to my adsl line dropping to 6dB again..

 

 

 

Powercut this evening has clearly dragged the SNR down load on one line, but overall looking solid!

 

Interleaving profile is now down to 8-4ms

Almost certainly not a port "swap", their port wouldn't have changed without someone submitting a service order or a fault being lodged, because no way a contractor would be doing the work for free :P

 

I imagine probably more likely the card in the cabinet he was on ended up with so many faulty ports that replacing the card was required, as it's much easier to swap a card out of the bin if it has a large amount of dead ports and send it in for repairs than it is to wire up an extra card into the bin.

That is the alternative certainly, Swap logic comes down from the typical actions we see in rural areas were equipment can't really be replaced quickly.

 

certainly do appreciate you keeping things honest and more accurate to field techs POV :)

 

 

 

IIRC your not part of the subcontracting group that typically causes the flack for poor or slappy fixes.
