I don't know if analog exchanges can support xDSL. I think not.
Yes they can. There are ADSL shelves that are separate from the exchange and the phone line passes through them on the way to the customer. I have installed some of those. I have also installed the ones that include digital phone lines on the same cards.
I don't mean ISDN, I mean POTS with digital exchange, vs analog exchanges: rotatrix, pentaconta... (I don't know the English names). Here there are a lot of 1240s. I think in Russia they even have multiplexed frequency transmission (hey, even Canada had it in the early nineties...). They can have xDSL? Wow. :-O -- Cheers / Saludos, Carlos E. R.
