I want to design an alarm phone cord ....
by way of working:
example the distance from the central telephone to the house within 1km, if among all these 1km there are disconnected, for example in the 300m point the alarm will active
how to detect it using uController , what could they?
because I was inspired with a TDR (Time Domain Reflectometer), which can detect disconnected cables to distances of several miles
