I always thought VDSL was limited to 70/10 MBit/s, but as of Sunday my line is sitting on 86/37. Even better is the fact that it's a new install with two lines bonded, so I'm seeing well over 160Mbit downloads in rural Waikato!

Is this likely to be permanent, or is it a VDSL glitch?

On the down side, I went from fast path (interleaving off) at 68/10 to having interleaving back on at 86/37

As sidefx points out, you have moved to 998.

broadcom chipsets given your over the 70/30 mark. Max you could hit there is 100/50 up from the 70/10 you were originally limited down to.

Love to hear details though, Properly bonded lines? or load balancing?

most lines are landing on DLM-2 or DLM-4 then moving back to DLM-1 over the next week or so.. assuming your line is nice and clean ild expect the 1ms latency will be back again.

I'm using two Draytek DV130 modems and a Mikrotik RB1100AHx2 router. Not sure of your definition of "properly bonded", I'm using MLPPPoE - it's really nice to be able to offer customers a full 1500 byte MTU as well.

Whole thing is powered off a modified Constant Vigil DC UPS.

The location is a 50 metre hop from the local exchange (no cabinets out here!), so with the latest 998 change, I'm showing an attenuation of 11dB (it was 8dB when on the slow 8b profile).

Stats below. Line 1 is clothed and has been installed since late August, Line 2 is naked and was installed in mid October,

My VDSL went from 17/4 to 17/2 since this new DLM ... can't wait for UFB
Lucky you!

do you know you are on the new 998 bandplan? it looks more like your connection is just degraded

it hasnt finished rolling out everywhere yet

i'd be interested once interleaving is off to see how low ping goes with that kind of sync.

Me too. It was down to 5ms to the first IP in a traceroute but now back up to ~18ms

are you terminating in hamilton or auckland? 5 msec to auckland would be pretty good, 5msec to hamilton is just "okay" (not bad by any stretch, but not diff from the lower upload speed etc connections) if it's hard to tell then ping should be about 1 or 2 msec extra to auckland, and so you can just ping auckland sites..

on that note end sites within the same city with good connections are usually the best for checking ping - sometimes it can be lower than first hop.

You're right i don't know.

Could just be my neighbours have taken up vdsl without master filters. I was the first ones to go to vdsl and was told I'm the last house on the copper.

VDSL at the extreme lengths is definitely affected by every other user. I was previously running two VDSL lines at ~1.4Km - in theory it was using vectoring, but each line was only getting 23/2. As soon as I got one disconnected the other went up to 31/4.

Both rather clean lines, Great to see! What isp did you end up going with to get MLPPPoE working? Last time i looked, really struggled to find isps that supported it!

vectoring is not active on chorus networks, so that was simply the effect of raw crosstalk on you.

I'm using HD.net - It's a business connection. Unsure if they offer MLPPP on residential lines.

familiar with HD, didnt realize they did MLPPP however.

With them, i would expect business, which was somewhat my expectation at the start anyway. Don't think there is really a residential isp that will offer it, Certainly talking about a niche requirement.

The one bit of using MLPPP that i never really thought about over VDSL is how differing DLM profiles across the lines would give an interesting result...

Yes, it seems to me that you ultimately end up with it running at a multiple of the slowest line speed and with the worst latency.

It's a niche product but I'm running a rural ISP and premium fibre, wireless back haul or hsns were the only other options.
