I do not know how to find what I am looking for on net, so I will just
try to explain how to reset your ADSL or other device via phone.
You can build a device that will use either power from phone/mobile
speaker to charge capacitor that will in turn disconnect the power to
any kind of device (power cord).
Idea is to dial that phones number and keep it ringing for a certain
period of time. Impulses from the speaker (constant (polyphonic) melody)
will keep charged a "electronic item/coil?" that will brake the power
circuit/cable of your device. I usually kept it ringing for 10 seconds
and after I stop calling, coil? will loose charge and return to the
original position again closing the circuit and allowing to device to
power up.
I am no engineer and my technical English is horrible, but I think any
decent electrician/TV repairman should understand what I am talking about.
It's cheap and dirty manual trick, but when push comes to shove you can
dial that phone and reboot the ADSL modem in no time.
