Hmmm, this might explain it...
At the time of my application, www.adsl2exchanges.com.au told me there were 35 ports free in my area.
It now reports 0 free ports.

i agree - the undersea cables are expensive but also the consortium make good money - its not easy to setup competition, when in KOrea at xmas - they had unlimited download very fast broadband & pay TV for less than we would pay for one service.
their internet was so cheap a few street market stalls would beam TV to their mobile in the slow periods/or just browse the net

Sorry Simon, I suspected IINET, but wanted to make sure. Better to ask and be sure than to guess. Yeah, ports can disappear quickly. They'll probably put another DSLAM in the exchange if there's room to give them more ports.

I put this situation down to outright highway robbery by the providers.
Running "ADSL" over power lines generates huge amounts of RFI. Some bands become unusable. How would you like your digital TV reception to spend 90% of the time pixelated or even reporting "No Signal"?

Dave, should you know better than that. Torrents have the potential to be illegal. There are numerous legal uses of them.

Do you propose banning motor vehicles because some people drive drunk?

That was illuminating Mr.B.

I'll definitely be talking to my ADSL IP about why my limit is 25GB (and I get shaped if I exceed that) while I can get 40GB (and get shaped if I exceed that elsewhere for the same price.
If they wont do a deal, I'll be ditching BigPond when my 2yr contract is ended and taking my business elsewhere.

It's not a matter of what I propose Andrew (I don't think bittorents should be made illegal, irrespective of how people primarily use them, for the same reasons that you make with banning cars because some people drink drive), it's a matter of what the RIAA and MPAA want. They are 2 very very very powerful organisations, with very long arms of influence within the US administration. Since the US has many trade agreements, with many different countries, and most of these agreements mean adopting US style laws (reason why Australia legally recognises the US DMCA I might add), it'll trickle down to us. There's already talk of ARIA pushing to have it banned. Politicians are pretty stupid as a general rule, and very out of touch with both the real world, and technology I might add, and they're gullible, and on the take from big business as a general rule. 1 + 1 =2, it's quite elementary dear Watson.

And yes, I apologised for my earlier misdemeanour about saying that torrenting was illegal.

Really ?

Where did you read that ?

The RFI can be filtered out at the coax , or by using FFT filtering of the TV signal (wait .... we already have that in our STBs and Digital TVs and Digital TV DVDR boxes, problem already solved).

A big trial in Tassy went extremely well from what I read about it.

That's about all you can do Ian. I think you're going to find that as time goes on, fewer and fewer ISPs are going to offer download plans more than 10GB or so. There's a tremendous amount of pressure from governments and big business to limit downloads, because there is a direct provable link between those who need such large amounts, and those that pirate software, music and movides.

I can't really do it on our Redback yet (we need to update the firmware), but on our other core routers (Ciscos), we can watch flows, in real time. I can see what internal IP address on your network, connects to which external IP address, on both sides ports. And I can deduce quite nicely what someone is doing. I generally wouldn't give a rats about it, but sometimes, we have customers ring us complaining "our Internet is really slow, your product is crap". And when you look at the flows, they're hammering the connection d/l crap lol. They get really quiet when you tell them that (politely of course).

Whilst this is real time, there's nothing stopping the police from subpoenering an ISP to track someones flows and using that as evidence.

For now, I'd look elsewhere. Westnet has a record for excellent technical and customer service, as well as good value. The ISP I work for (ECN) has very good tech and cust. service, but is pricier.

Ian, it's not recommended to be filtering the crap out of the signal. Every time you filter, you lose data, and there are overheads that filtering causes. Better not to do it.

Most of the US's infrasctructure is poorer than ours believe it or not. It's older, and falling apart in a lot of instances. Our problem is that Telstra owns most of the infrastructure, and because it's now privatised, share holders don't want to 'waste' money fixing problems (less profits). Google CNI faults. Telstra has CNI faults nearing 10 years or even more - without being fixed (and they have no intentions of doing so I might add).

A few things that people don't generally know - in Australia, ISPs can't:

1) complain about other ISPs

2) complain about wholesalers

3) customers (end users) can only complain against their ISP, not their ISPs wholesaler, even if their ISP has done nothing wrong, and it's the wholesalers fault.

makes you think eh?

Sorry to butt in.....

BPL (Broadband over Power Lines) or PLT (Power Line Telecommunications) is a technology to enable the delivery of high speed data service over the power distribution system.
This technology injects high power, high frequency (typically between 2 and 80MHz) signals over the power distribution network to deliver high speed data services to homes and businesses. This type of BPL is termed "Access BPL". There is also "in-house BPL" which uses building wiring to distribute data service throughout a building. These systems are currently incompatible.
What is the Issue?
The issue is that there is a high potential for interference to the high frequency spectrum through the use of this technique. It has been described as "spectrum pollution". This is mainly due to the power distribution network not being an efficient and effective medium for the transmission of high frequency data services.
It creates interference to such a level that a HF spectrum user within the trial area cannot hear or transmit a signal. Due to the nature of the high frequency spectrum and its ability to propagate long distances, this interference can propagate around the world.
This causes great concern about this technology not only now but into the future when the sun-spot cycle improves propagation. The technology is also prone to interference from other transmitters in the area.

I watched that program on (ABC ?? ) too and am aware of that rediculous situation , and I have written to my member of federal parliment about it. Too bad more aussies don't or can't be bothered doing similarly.

Yes I know how signal filtering works , I have studied analog and digital signal processing and several subjects focused on communications engineering (as part of my second BE).
I know about s/n ratios and the effects of filtering.

So I suspect do the TV broadcast engineers.

So what if the ADSL and ADSL2+ produce some induced RFI in the power lines, and how's that different to the induced RFI produced in the telecom copper network and phone lines that enter all our homes, or are transmitted by our PC and USB wireless adapters that many of us use to wirelessly connect several PCs in different rooms to a central ADSL / ADSL2+ modem ?

There is no need get personal about this either ....

Ian - I wasn't aware that I was getting "personal" as you put it. I was simply replying to yours (and others) posts. If you interpreted it in another manner, such as a personal attack, then I'm sorry. That certainly wasn't my intention.

You are converting kilometres of 50Hz transmission wire (aka power lines) into radio transmitters. If were were talking underground power there is cable shielding, but generally speaking we are not. The projected use for this technology is overhead, with no shielding or other forms of RFI suppression.

I'll back that up, have been a Westnet(now owned by iiNET) customer since they advertised by putting up photocopied adverts in computer shop windows
Before that I was an Up'N'Away(also recently acquired by iiNET) customer because they allowed multiple dial-ins to one account. Those were the days

I'll back that up too I have been with Westnet for about 10 years(?) started with dialup and now broadband, I have tried others but went back to westnet after about 3 months.
Never had a problem that couldnt be fixed with 10 mins on the phone (all my fault by the way)

We are talking a 5V or something as trivial (can't recall the V and I requirements over telecoms lines (phone lines) , been several years since I did the courses), which will be high kHz or low MHz superimposed on the 50Hz AC signal (power) .... trival signal intensity for any ADSL or ADSL2 leakage.

Take a look at the RJ11 or RJ12 cable coming out the wall and going to your modem or PC . It has no effect on the analog and digital TV picture , and that cable once it enters the house is unshielded too.

That wireless adapter has no effect either.

Why would a home user need so much download? I have a bigpond 12g limit (includes uploads) and don't reach that ever. This is even with my son playing online games. I do restrict video watching and we don't download illegal movies etc. The movies are better quality from the video shop anyway.
