Hi Bob, Phones & power is an interesting topic....
As you say, the old phones used to draw their power from the actual phone line, so would keep working through a power cut. However, go into any phone outlet/seller now and you will be hard pushed to find one of these basic phones. Most of us use cordless sets, which require a power supply, even many of the single unit phones have answering machines et al, they also have their own power supply. Of course, most people tend to have mobile phones now - so they are covered when the power goes out (as long as it is back on before the battery dies!). I've got the cordless baseset plugged into the UPS - so the phone will keep working for a while (depending how quickly I shut down the computer). Of course, if you rely on VOIP (as in Naked DSL) you also need to keep the modem up and running (get a big enough UPS!). Regarding the phone line deterioration - this is definitely a problem which affects data/ADSL long before it gets bad enough to affect the voice calls - I had variable problems for over a year at the old house which was due (knowledge in hindsight!) to corrosion of the line - the trouble was it came and went (presumably with the weather - with a time lag for the capillary/seepage effect) and the various Telstra checks just kept reporting that there was no problem with the line. One day, it suddenly got so bad that there was actual audible noise on the line - at that point the (dial-up back then) internet connection had effectively disappeared and, finally, it showed up as a line problem that the telstra guy came and fixed - the connection speed was then much better than at any time I had been in the house - so the problem had obviously been developing over many years! I guess that is one good thing about the old analogue voice phone - it keeps working over REALLY crappy lines! Have fun, Neil - who seems to have rambled well off-topic this time :) -- Neil R.
