DSL-Extender Brings Broadband 20km
An anonymous reader writes "Whirlpool outlines Telstra's new DSL deployment: "Telstra announced a trial of the technology back in January, saying it would allow DSL to be connected to people who were up to 20km from a central exchange. DSL Extenders work by splitting an existing copper phone line into eight separate ADSL lines using a tiny, ruggedised remote DSLAM.""
When they talk about the extender DSLAM hardware being rugged they aren't kidding:
Only the size of a small shoe-box, and being fully submersible to a depth of 5m (16 feet), the R8as can be deployed in more locations than any other DSLAM. It can be installed on a pole, or in a pit or manhole susceptible to flooding, as well as other locations such as un-powered cross-connect cabinets. Its small size and light weight also allows it to be suspended from overhead cable.
I'd like to know if they were serving DSL through a submersed DSLAM during the testing phase. I'd really like to know if works as well as they claim.
...it isn't much beyond an incremental sort of gee-whiz improvement. You can send T1s over long distances and then break them out fractionally or hook them to a DSLAM and use as a backhaul for the customers. The submersion thing might have come about from submersible communications at sea or from the fact that many remote mechanisms in telecom tend to be underground and the waterproofing for those vaults tends not to be the greatest.
I give it a big shrug and a I'll check into it later. I work in telecom so it does get my notice. Now if they make a 1.5Mbps line work to twenty miles on pure copper all the way, that will knock my socks off.

Please sir, may I have some broadband?

You don't have to be very rural to wish for broadband. The nearest broadband of any sort is 10 miles away, even though I'm less than a half hour from Dallas.
I started to wonder why this development was happening in Australia instead of here... then I remembered that 1) Australia has even more empty space than we do and 2) US telcos are a bunch of greedy bastards, and the limited rural market won't add enough to the bottom line.
Stressed? Me? Of course not. Stress is what a rubber band feels before it breaks, silly.
This has always struck me as stupid.
Copper: great for POTS, crap for data, ubiquitous. So they invent DSL to compensate for copper's inadequacies.
Fiber: crap for POTS, great for data, ubiquitous right up until the end of the street. DSL doesn't work because its a copper technology, so these poor people who are feet away from all the broadband they could ever need can't access it because telcos only know how to do DSL.
I'm not oblivious to the fact that it costs more to split fiber (light doesn't split like electricty), but thats because we don't do it very often as the priority has always been POTS. How long will it be, now that data outweighs POTS, until we get fiber to the front door?
Scared of flying, pointy things snce 1979!
A friend of mine did do a fiber to the curb sales pilot in Texas for quite a well that could give insane bandwidths. In fact I think Verizon ran a DSL fiber to the curb trial in Arizona where you could get 50+ Mbs up and down.
This is my sig.
If this technology had been available even five years ago, it would have been widely used. Now, I question whether it is going to be an economic solution. Recent advances in wireless technologies seem to promise a cheaper service in remote areas while being able to provide similar bandwidth.
