Hello everybody,
I´m searching some time ago for a PCB card or a modem with some I/O contacts, which might allow to connect and control thought a phone line.
The main idea is with those contacts be able to turn on/off and also status of an equipment remotely.

I know that Siemens add some time ago something of this type, but so far I was unable to find it from that brand or other.

Can someone give me a clue of some manufacter or model?


All the best
