Well if Telecom is going to stick to its June promise for starting to install ADSL2+ dslams, any idea where they are likely to start putting them first? Hopefully they will run a list on their website of enabled exchanges at least.

Thinking about getting an ADSL2+ router but don't really want to get one till the local exchange has it, or when some other ISP puts their own gear in the exchange.

I'm sure any dsl equipment that Telecom has been putting in for some time is already 2+ enabled.  Is anyone still manufacturing dsl1?

I wouldn't waste my money on a dsl2+ modem currently.  Telecom could be giving us 8mbit dsl connections now but they're not.  What makes you think that you're going to get a faster connection any time soon if they put a dsl2+ dslam in? 

In AU it took 5 years and a second regulatory change between UBL happening and ISPs delivering DSL2+ services to domestic customers.

If you're moving from DU to DSL and not getting a free modem with your connection then grab a cheap one of TM.

Cheers Don

was ADSL2+ technology around for mass market implementation when UBL first happened in Australia though?

Jaffa: ADSL2+ rollout is still commencing. Expect to be using it soon if your on one of the NGB exchanges. I already have it :P


Cool! Could you elaborate a little please?

You missed my point...

It took ISPs 5 years to get any dsl equipment in to exchanges for domestic users.  1 or 2+ wasn't the point, thou I accept it is the point of this topic.

ISPs weren't waiting for dsl2+.  It simply wasn't viable to put equipment in exchanges untill UBS.  UBL didn't do it.

Cheers Don

Jaffa: I cant discuss to much as adsl is a touch subject at the moment anything could throw a spanner in the works...

Well if they offer up a full speed dsl1 then I might even consider dumping my woosh connection and coming back...  I'm getting tired of the woosh gateway for my phone service locking up every other day.  I'm tired of the dam echo to Telstra Clear customers (I'm really sick of their level 1 helpdesk guys telling me it's a problem with the signal on the radio link!) 

I'm not going to hold my breath for either woosh to fix up their crap or Telecom to deliver full rate dsl to me thou....

Thou I also see no commerical reason why they shouldn't deliver full rate dsl with appropriate data capping on it.

Cheers Don

Ah yup, just wondering if there is any benefit to us upgrading to ADSL2+
the Nokia m1122 we have at present can only connect at 1.3mb due to distance from the exchange (approx 4kms), wondering if the distance improves using adsl2+, if so then it might be worth while upgrading, otherwise we have to wait for Telecom/other ISP to install a mini-dslam in the roadside cabnet about 100m up the street.

You mean the bandwidth problems aren't bad enough with only 3.5Mbps? Just imagine what would happen when they increase everybodys caps to 8Mbps. People would end up getting 100Kpbs. And they wont be spending any money upgrading old ADSL equipment.

bradstewart:  You mean the bandwidth problems aren't bad enough with only 3.5Mbps? Just imagine what would happen when they increase everybodys caps to 8Mbps. People would end up getting 100Kpbs.

Sorry but I don't understand your argument at all.  Why would people end up geting 100Kpbs if the link was opened up?

Logic says that if you open the link up to faster speed then the data moves from the agrigator to your computer faster and hence places less load on the network, not more.

bradstewart:  And they wont be spending any money upgrading old ADSL equipment.

That statement makes even less sense to me than your previous one.  Can you explain the logic behind your view?

Cheers Don

If you read some of the recent threads round here you would know that a huge number of people are getting slower speeds since Telecom increased speed to 3.5Mbps.  Im saying if Telecom further increased that speed then those bandwidth problems would be made even worse.

they should just pull up the whole goddam network and lay new lines down that can actually handle these speeds, whats the point upgrading speed if the lines cant take it?

Ok...

1.  It's not supprising that people are seeing slower speeds since the increase to 3.5mbits.  Telecom have been doing a big marketing push at the same time.  I suspect that there has been quite a number more customers join the service at the same time.

2.  In addition to the customer increase the amount of data on a range of plans has also gone up.  How many customers have upgraded their data allowance with the speed increase?

3.  I checked out the links you posted and there's a few of technical considerations that haven't been made.

3.1  Speed and data allowance both affect the thru put.  If you change 100 people on 1mbit conections with a 1Gig data cap to 3.5mbit with a 1Gig cap then you're going to notice a difference in performance because the data is moving faster.

Thing is that this hasn't happened has it?

3.2  The service is still running a 128k back stream.  Now if you're running UDP then this won't have any impact.  But for TCP data the lantancy hasn't gone down. 

3.3  What is the ERX platform doing to deliver these new rates and is the ERX copping properly?  (I notice that the link J provided doesn't talk about agrigator issues at all.)

Cheers Don

Jaffa: 0-1kms 24mbs

1.3-2.1kms 18-24mbs

2.1-3.3 10-24mbs

3.3-4.5 6-24mbs



Taken from a ADSL2+ speed graph these are results conducted in a lab reality will change these figures.


Are these taken from the exchange or from the cabinet?

Isn't NGN about laying cable from the echanges the to roadside cabinets so the length of copper to houses (especially CBD) will be pretty short?
