Jules,
Here's another. About 15 years ago, Telstra made a very large purchase of solderless line connectors from a nameless US company in Minnesota. They were bought for their field techs to use as joiners in junction boxes, both at street level and in home junction boxes.
These connectors take the form of small transparent, plastic bubbles, about the size of a fingernail. The wires are pressed into the sides to make the connection in a viscous, conductive gel within. Their life is measured in hundreds of years......
Except now an insidious corrosion problem has crept in, and resistances are steadily rising. The line is clear until the junction box, then signal can't easily get through. Result: bad coms, poor intelligibility, very slow data transmission.
These connectors are everywhere, and probably responsible for Jules' problems. Replacement right across the network in every state of Australia will cost many billions of dollars. Telstra by law is obliged to hire out its infrastructure to other carriers at giveaway rates, which take no account of maintenance costs and certainly don't factor in replacement of these gel connectors. The copper network is failing fast, long, low density traffic (= rural!!) networks are suffering the most, and the situation will inevitably get much worse as Sol fights the Government on line rental to other carriers. Sol only has to sit around and do no maintenance, and the Govt's share in Telstra will dwindle to below $3 a share. As fixed phone rentals steadily drop, cell phone usage will escalate with other carriers, costing Telstra revenue. When the Govt's hand is forced (and this may not happen since the Govt is enjoying large income from a mining bonanza!), they will cave in and Telstra rental rates to other carriers can be boosted, and soon after, maintenance begin.
I have had Optus cable since 1997, nine full years. In 2006, no Telstra cable is available in the Heidelberg area of Melbourne, and yet we are only 13 kms from the centre of Australia's second largest city of 3.6 millions. Only ADSL is available on their antiquated, copper network, which has been in position for more than a hundred years. This gives some indication of the political paralysis playing out between Telstra and the Government.
Sorry, a bit off topic.....
Cheers,
Hugh
