Dear Friends!
Greetings to all. I am going to design one project using Land line telephone(Security Purpose)
1. I have oral idea about telephone that how telephones are working and basic ideas to send Voice signals. I want to use both pulse dialing mode and Tone dialing mode. However i want to get clear circuit for my project. I have lots of questions to clarify
In Pulse dialing Mode
How can i send mobile numbers to PO.Either both the lines should be shorted are both the telephone wires should be terminated. I googled about this, but answer is need to short. If we short two lines means by chance wire will fired.
Need proper ideas and proper design,, kindly help me

Happy weekend guys
