I implemented this circuit stripboard layout but when I connected this device to phone, there is no pulse in phone reciever. Please notify me what am I doing wrong!!
And here is my implementation picture. The 2 wires on the right are for output from my implementation to the phone.
The wires on the left are connected to the phone line that is input from the service provider to my circuit.
Please please help me. Please tell me what is wrong in this implementation. I would be very thankful.
edit: Here is the picture of the bottom. I made sure that the lines and connections are not short column wise. It may look that they are short in the picture but they are not!
I measured the voltage across all components in this circuit, But I was astonished that telephone line(Service provider line) has 50V DC and my input wires which are connected to service provider wires are just providing 4.86V DC to the circuit. I am using CAT 5e wires for input and output. The voltage across every component is 4.86V DC except the voltage across the transistor and 220 Ohm is 4.01 V DC. Now please somebody help me.
