Hi drashek here again. Good response in Commentos, one thangee' new 100 Mb/s bell modem need more than simple twisted pair, in fact 3 wiires running simultaneously is minimum or 1 & 1/2 telco line teisted pairs.

Now in theory, each phone line is 2 sets of twisted pairs called full duplex. long ago meaning of full duplex was twisted about, as speeds are so low at home end.

now ethier force telco to give up full duplex line at ordinary rate of 1 landline or 2 twisted pairs or need to buy two seperate crimped lines, giving user one unsed Wirelins & 3 Wirelines used into modem. NOT really that Hot. Old c rap into new market of you th. Naiveely buying any 'ole stutter & crackle.

Intresting: in BELL system today, QWEST has been sold, now lousiana company called century communication has bought former baby bell: northwestern bell from present owner qwest & qwest in Denver becomes just another copper plant.

However, century income is based on rural subsidies from US Gov't & those subsidies are about to be withdrawn, leaving anal ists pondering, will that even work. YES, due to fact telso gross profit is 70% of income, pretty hard to lose.

Telco at bottom line never claim to make any profit, leaving investors lesss intrested. qwest came on strong at $65/sh in 2000, now $5 share. Century has $35/sh base to lose from, in real background people are swarming from telcos'

Cable phone & Mobile have replaced landline at rate of 10% per year. So long Ma Bel. Took Lifetime to cripple.

Better an Upgrade from the sorry DSL than wiat to have the streets outside ripped up to get the fiber in. Maybe they can use the extra time to plan the Fiber Upgrade... lol right!

Existing copper lines can be coupled and operational in under a week whereas blowing fibre into a building often has a lead time of 30 working days.

It may not be technologically superior but there are lots of circumstances where that time difference is absolutely critical.

I don't see why people have a problem with this, a speed upgrade with minor additional investment is a good thing.

It seems like people are being sucked into the marketing hype. Fiber optics is better than copper when it gives you better speeds at a comparable price. But if I'm not going to pay for a high-speed FO connection (I have other priorities, after all), and the cheap copper is as good as the cheap FO, then what's wrong with copper?

Graham - Your analogy leaves something to be desired. Repaving the road instead of patching it is a bit like replacing old copper wires with new copper wires. Repaving gets you the original infrastructure. Would you re-route the roads to fix the potholes? And as far as "copper wires that were intended only for voice comm bandwidth", well that's a bit like saying the roads were built for fossel-fuel powered autos but now we have hybrids and plug-ins so we need new roads.

Gbit also works over twisted pairs copper, so the point is that it works over normal telephone lines, that it works over copper is not news.
So did the brits get rid of that aluminium telephone wire yet? Or do these guys have to think up something that works over aluminium?
Would be funny if they discovered a trick that only works over aluminum that doe 600Mbit.

300 Mb/s is for 400 feet. Already Cable Gives 50 Mb/s thruout System & Worse, this is in response to Marvels late day announcement, yesterday, new modem/router carries 100 Mb/s to 2.5 Gb/s & does Light. So Bells good idea & better than Today, yet NOT really in Cards of Future, more tailings of past, in Very Limited System.

PS Ms. Barak Broke Marvel Light Modem Chip Story Late Yesterday.

This is like the road network,they keep patching it up until one day they have to spend a fortune on doing a proper job.
Stop arsing around with copper wires that were intended only for voice comm bandwidth. Do the job properly now or we will be forever crawling along trying to catch up.

interference between physical and virtual channels?

What would happen to 300Mbps over copper wires which are affected by both water & heat and less then 450m away from BT exchange, my 20Mbps O2 is!
Please give us either cable or fibre, my house wires should be replaced along time ago!
