Telecom will be offering FS/FS and FS/128kbps UBS plans from 26th October 2006. FS/FS replaces the existing 3.5mbps offerings.

ISP's can request interleaving turned off for a UBS service.

This is avaliable for all ISP's with a wholesale agreement with Telecom, not just those in the ComCom ruling.

Also this may be of interesting to some if you didnt already know:

http://www.telecom-media.co.nz/resources/adsl-performance-report-250706.pdf

What some of the more astue members of the telco industry have pointed out is that as the number of adsl services increases cross talk also increases. Also as the amount of spectrum utilized increases (eg number of frequency bins) cross talk again increases.

So faster DSL for all actually means slower DSL for some, no change for many and some improvement for a few. This is before you even take into account the backhaul contention.

As shown in Table 1, 86,858 customers (22.7%) do not achieve the provisioned data rates.


Thats alot of dodgy ADSL connections and that number won't be getting any smaller!

From memory, many were full rate (8M/1M) customers who would never get that...

Oh, and to be picky... if I understand it right, it's both RUBS and CUBS.

RUBS however will be with 128k upstream, as per the ComCom's determination, so I doubt that Ihug and Callplus will bother with it.

I'm curious if Telecom will provide "naked DSL" already. They told me no earlier, and said it's just like normal CUBS with tweaked speed profiles - same choked backhaul too, presumably.

RUBS will also have a FS/FS offering, so basically everyone has the right to FS/FS now.

Ohh, that's interesting.

I thought RUBS was on hold because Callplus and Ihug had gone to the High Court to challenge the wholesale price.

The pricing seems quite reasonable to me - If I could actually get FS speeds. Sigh, its like leasing an Aston Martin with 1 L of gas in the tank and no way to top up :)

Also ISPs can resell Telstra Cable now in the Hutt (have been able to for awhile) but also shortly in CHCH too. Data only service @ Layer 3 AFAIK.

Will there be any data caps imposed on each user as is the case now?

Fixing this is simply a matter of putting the dslam closer to the customer, which is what is being done at present, isn't it?

What does this data really mean?

Yes, I expect Telecom to have completed their mini DSLAM roll out by October 26th ;)

It means line noise is going to get worse in the future, thus more dsl problems.

This is a rant that many 'astue' members of the Australian industry had at the start of the decade in Australia.

At the time, you would have thought the Chicken Little was going to be right, and that the sky was indead going to fall. 

AU is now boasting a growth in ADSL2+ services.

The proposed node network in AU has been pushed off the table by Telstra again and it's business as usual.

See:  http://www.iinet.net.au/about/media/releases/The-Myth-of-Fibre-May-06.pdf

Also see:  http://whirlpool.net.au/article.cfm/1633

Can anyone explain to me why some mobile installations don't seem to require 19" road side cabinets while others do?

Cheers Don

Two things here, one they freely admit that many customers have not upgraded to ADSL2/2+. Once a larger number of ADSL services transition to ADSL2/2+ then your would expect those figures to change, for the poorer.

Secondly these are Australian figures for Australian lines and population densitys, while these are not as disparate as other western countries I would put money on the the population density of Auckland being lower than Sydney and their local loop being is in better average condition than ours.

Dont get me wrong I'm not saying the sky is falling, I'm simply pointing out with the current network infrastructure that giving a "full speed DSL service" is going to result in expectations not meeting up with reality for a lot of users.

What should Telecom do then? Reduce bit rates through less power?

From a technical point of view the obvious solution is to continue the roll out of roadside cabinets. Also what they have mentioned is tigher controls on CPE devices, eg power levels used and backoff behaviour. This is hard to implement after the fact however with so much gear already out there.

Then again maybe this is all a ploy so Telecom can say "Well we were going to invest but you shafted us and look what you get, we gave you full speed services with the current network just like you wanted. Works great huh?".

Agreed.  That's by far the best way to make the best use of the existing resource.

Fraktul: Also what they have mentioned is tigher controls on CPE devices, eg power levels used and backoff behaviour. This is hard to implement after the fact however with so much gear already out there.


No.  This is stilly.

What they should do is some simple modem testing like the APC magazine did a few month ago. 

There is no difference here between the days of dial up, where customers who purchased cheap modems got poorer results.

Tightening up the controls is only going to reduce the choice of product out here.  For many people, a cheap modem is all that's required.

If my connection ran at ~500k up and anything up to 5mb down I'd be fairly happy based on my current requirments.

Cheers Don

1. Connect more customers.

2. Get DSLAMs closer to customers.
