The current EUBA implementation is a little up in the air really as not even Telecom have a standard way of presenting it to ISPs. Only a few nights ago at ISPNZ a number of ISP heads were talking about them having difficulties with the implementation as its not as easy as just using the L2TP tunnels.

Obviously ISPs want to use EUBA for various reasons but unless there is an easy way to provision them each then it could become a bit of a non starter.

Would be interesting to know what hardware the ISPs that are currently using it as their standard residential offering are using. Also whether they are using 1 CVID per customer of if they are able to have many customers aggregated into 1 SVID.

I would be very interested to hear what sort of problems ISPs are having.  The architecture is very standard so any decent BRAS will handle it just fine.

1 CVID per customer, aggregated into 1 SVID per DSLAM is correct.

Cymro:
Nil Einne:
But if not, it seems what happened is something like this:

1) Telecom Wholesale launched EUBA0
2) Telecom retail move to EUBA0 for people in EUBA/ADSL2+ areas
3) Telecom Wholesale stop supporting ADSL2+ on BUBA


Sorry, but that calls for tinfoil hat cat:


Well I'm not the only one to notice http://www.geekzone.co.nz/forums.asp?forumid=81&topicid=68163 how Telecom Wholesale appears to start enforcing things when it seems it isn't going to disadvantage Telecom Retail as much as other companies. Given their is obviously a strong history here, I don't think it's completely unresonable to think they might not actually always be as independent as they are supposed to be.

Note that this doesn't require any conspiracy, just people, potentially when they're not even concious of it, making decisions they wouldn't have were it to affect the people they used to work with a few years back (and who still work for the same company after all even if it's operationally seperated). People are funny things and have a tendency to be influenced by any number of things, often without really being aware of it and even when they know they shouldn't be. There's a reason why it's so difficult to manage such things, humans aren't robots after all.

In any case I do intend to write to the CC if this isn't resolved. Whether my ISP is wrong or Telecom Wholesale have started enforcing no ADSL2+ on BUBA it's something they I would hope they would look at. (In fact one of the reasons I asked here was precisely to get some info before writing to the CC.)

BTW, someone asked my sync speeds, they are 8192k, 894k. Fairly high i.e. shouldn't be a line issue, not that surprising since I was cabinetised. It was originally suggested I may just have to wait, but I was cabinetised in March so I doubt they're still testing anything. And I'm resonably sure it isn't a modem issue since I have 2 ADSL2+ modems (Speedtouch 536v6 and Dynalink RTA230), both of them can't sync at ADSL2+ only ADSL/G.dmt. If I try to force ADSL2+ (Dynalink only since the Speedtouch doesn't let me change from multimode) it just doesn't sync. I also know both of them used to sync at ADSL2+ before I was cabinetised (the problem may have begun a few weeks before then, I'm not certain). So I'm fairly sure it's a profile issue. There's some more info http://forums.slingshot.co.nz/viewtopic.php?f=15&t=3708 if anyone is interested.

Hi, 8192k for download is not flash and not much over ADSL1, could it infact be that your line length or condition (house wiring especially) is such that something is not right in that area, and the two modems that wont do ADSL2 are doing so because the higher band signals are marginal so force themselves back to ADSL1.

Bodiew - Slingshot Tech Team Leade:
Your profile on the port is ADSL1 as you are subscribed to an ADSL1 service. The part about 'optimized' for ADSL2+ is wrong and has been flagged to be removed. Hopefully that clears this matter up.


So in that thread a Slingshot Tech team leader suggests that you are actually on an ADSL1 Plan with Slingshot and that their advertising is misleading and needs to be changed as they promise "Optimised for ADSL2+"

So yep, you should contact ComCom, but this has nothing to do with BUBA Vs. EUBA.

Embarassingly I have to admit I was wrong (mostly).

The reason why I didn't have ADSL2+ was because I was still stuck on UBS. Someone at SS realised this could be a problem and they checked my account, confirmed I was on it, and had me moved. I could then/now sync at ADSL2+ speeds.

However I haven't yet seen anything to convince me that the people at SS who told me Telecom is rejecting requests to move people to an ADSL2+ profile were wrong or lying, I suspect they're right but only for UBS. It's possible Telecom have always done this although as I noted I used to get ADSL2+ sync. However as UBS is a grandfathered and dying mid next year plan, I can understand Telecom's attitude here and don't find any fault with it.

I am of course a bit annoyed it took so long to get resolved. But I did primarily rely on their forums which aren't an official support method. However after being told I shouldn't have ADSL2+ only to contradict them with their website and then finally working out (primarily from the forums) how to get them to request my profile be re-done only to have this was rejected and then being told (a few weeks later) it was a problem on my line (contradicting what I'd been told in the forums) which they could help me diagnose, I semi gave up the official ones (I wasn't surprised how hard it was, I somewhat expect and understand why it's like that and not just with SS).

Ironically when I first looked in to this in May (SS only seem to keep threads in their Internet Service forum for a 3 months or so and I didn't keep a copy) and was told about the Telecom rejected request because plan isn't ADSL2+ thing I was wondering if UBS could be a problem but I mentioned UBS, no one from SS seemed to think it could be an issue and I decided I'd probably long been moved off it since it was being phased out. I always had a nagging feeling that could be a problem but no one mentioned anything but clearly I should have looked in to that a bit more.

Cheers and thanks again for everyones help and apologies to everyone especially those at Telecom for any confusion caused.

ADSL2+ is available on UBS, and has been for many years.

EUBA - Enhanced UBA is delivered as Ethernet over an ADSL2+ copper interface.

Real time grade IP traffic – delivered as a real time CoS.
Internet grade IP traffic – delivered as best efforts.
This will achieve a 99.9% probability of providing end-users.
Enhanced UBA currently has one profile for best efforts traffic only and three profiles for guaranteed real time traffic:

Unlimited Enhanced UBA 40.

The 40kbps, 90kbps and 180kbps refer to the bandwidth of the real-time channel of the services. This channel is optimised for digital voice services to ensure one or more high quality voice connections.

VDSL

Speed

Access "triple play" services - video, data, voice.
Use online storage solutions.
Upload large files.
Support more users on the same internet connection.

Unmetered

Internet is essential for everyone and for successful small and medium businesses, with restrictions on data usage hindering internet uptake, rather than encouraging use to it's full potential.

cbrpilot: ADSL2+ is available on UBS, and has been for many years.

Sorry for semi resurrecting this old post but I saw it because of the new reply although that doesn't affect my response. Anyway are you sure it was at the time? As I said, all evidence suggests I was on UBS at the time and had ADSL2+ sync precabinetisation until I was moved to a cabinet when I was limited to ADSL sync and when a request was made to move me to a ADSL2+ profile, Chorus rejected this request. It was only when I was changed to UBA that I was allowed to get ADSL2+ again by Chorus. As I said, considering even at the time UBS was grandfathered I had no complaints about Chorus (still part of Telecom at the time) refusing to supported ADSL2 on it, regardless of what they had done in the past, I'm simply pointing out I haven't actually seen any explaination or evidence suggesting this isn't what happened.

Nil Einne, you're digging into the very distant past now.  I am fairly sure that ASDL2+ was introduced before xUBA, but it's so long ago .....

I can't comment too much about what happened in your situation, or if you were given the wrong information at the time seeing as you would have been talking to your ISP, which was talking to Chorus (then Telecom Wholesale).  Chinese whispers?
