I have a DTMF tester diagram using MT8870 the circuit connected to the telephone line. When I press any key in the telephone it will output the converted binary value & displaying through the output LED’s.
My question is
For example let say my land line number is 1234 & my friends land line number is 5678.
When HE DIALED my number from his land line phone what is displaying in the DTMF tester circuit?
Is it displaying the converted BINARY value of his number (5678) or my number (1234)?
Thanks
