Re: Solution for POTS
So in addition to BT having a large very resilient power supply at the exchange location every telephone user will require an additional power supply at their home. As another poster said how green is that?
Good point, and a standard phone will work just lovely with 50V line current, which is both battery and generator-backed at the exchange, but... but I already have my modem on a UPS, alongside my DECT base station. It sort of helps when there is a power cut (and for semi-rural Wales we get more than you might expect) and you need to consult the website of Western Power to see a: if they already know about it and b: what the contact number is if they don't.
