Hi All,

Mark Petrie (CTO) of Snap Internet kindly offered for me to be on the VDSL trial, so far I'm loving the speed - here's my short write up on my experiences so far - http://blog.nick.mackechnie.co.nz/post/2011/02/02/VDSL-is-here-in-New-Zealand.aspx.

Nick.

I'll have a read when I get a chance.
Very interested in getting vdsl2 now our exchange has been upgraded and I've heard good things about snap.

Nice. I've been waiting to go on a VDSL2 trial since 2009. Last year, it looked like it would happen, and the cabinet went into place but... Telecom Wholesale pulled it, due to regulatory issues.

Before you harass Snap, head over to www.telecomwholesale.co.nz and use the tool there to find out when your cabinet supports VDSL2. Unfortunately, I can't have the service yet, because my ISAM/DSLAM needs a software upgrade that won't be done until sometime end of this month.

Curious to see that you're "150 miles" away from Snap :). Maybe that's Telecom's Dynamic Line Management punting your packets through an unusual route?

Shame about the upstream being limited to 10Mbit/s when you can by the looks of it get 25M or more. And PPPoE, yuck.

I was talking to Mark about that, shame I don't get adsl2/vdsl until November :-(

My cabinet says Feb 2011.. Do want!

my address shows that it is covered for ADSL2+ by the exchange but there are no cabinets planned with reach to my street therefore no VDSL footprint.

maybe i'll get FTTH first instead :P

and whats wrong with PPPoE? I've always found it easier to deal with than PPPoA - no need for half-bridge mode etc on the CPE if you want to deploy a decent firewall instead.

Would prefer no PPP with 1,492 byte MTUs, random dropouts, etc. It's an additional complication which is nice to do without if possible.

Nick - looks like excellent local performance. What sort of results do you get on an International speedtest?

I hope that I can get that at my home soon. Apparently my cabinet will be VDSL capable this month. The only question is when will it be broadly available and will Vodafone have a VDSL plan.

Have had a VDSL connection through TelstraClear at my office for the last year or two. Very happy with the performance when I've used it (it's not our primary Internet link).

Is the download speed limited at any rate?

fair point on the MTUs. why do they still use authentication even? is it for billing data? is it to protect you from 'stolen' adsl by wiretapping?

PPP is one of the simplest ways to meter data going thru a pipe, It put's it nicely in a SQL db for you to work with :)

MTU is just laziness/Telecom, No reason you can't do a 1508 MTU on the dsl line and allow for full 1500byte frames

Here's some international speed tests.

As per Mark's letter, It may well be (See blog for link).

No, not according to what Telecom Wholesale told me. Upstream is limited to 10M though.

Hi All,

Your right Juha - that increased latency on the link caused by DLM/Telecom Wholesale not allowing the interleave off option which will cause speedtest to assume that you are quite a lot further away than you really are, for Nik that is about 800 meters to the ISAM, then a few meters to a 7450, then 5Km back to Snap's DC with the speedtest server.

From what we have seen we have not noticed any download limits, the highest download sync we have seen is around 80mbit, which had an attainable of around 70mbit up - one thing to note with that type of speed is if you intend to route (and most people will want to run NAT etc) then most SOHO routers will max out their CPU at lower speeds than that, I.E even most Cisco 800's will struggle to push more than around 50mbit with NAT enabled. the ISAM's can also do VDSL profile 17a (check it out on wikipedia) which can do up to 100mbit.

And on PPP - we have some plans for removing this in the future, we are trialing this too at moment, but you are right PPP is very handy for accounting and authentication.

oh and WJW - does this mean you are happy to cancel that special cable connection you happen to have at your house:) you would need to work out routing your native IPv6 allocation to it too!

No interleaving off is yet another example of Telecom crippling broadband services to protect their other revenue streams (HSNS) along with pathetic handover capacity limits.
