Hi
(Scratching head a bit...) I did BE project in communication and hence come
to know that the telephone ring used in all exchanges is 75V AC RMS, riding
on -48V DC, to facilitate dialing from ringer (mechanical spring dialing,
old style) fones.
Now internal modem derives power from PC power supply only. Given the
reputaion of indian government service, how safe internal modems are, from
passing the surge to the Mobo?
There are protective circuits etc. on modem but mobo power line directly
connected to exchange one is rather hairy scene to me. Especially when
polarity reversal is not impossible with exchange(Happens with electricity
board too...)
I prefer external modem just for this reason...
Just a naive thought...
