Hii Friends,

I been under a project of Interfacing 5 Telephone lines
with a controller (PIC18F452). The overview of this project is to get
the caller number and store it to memory. can you guys please help me
about how to interface the telephone line with PIC. I have a basic
idea and would like to share with you.

I decided to use a decoder to decode the Signal and to receive
the number. If it is possible?.Also, i would like to know that a
single controller is enough to interface with 5 telephone lines. if
any website has the schematic please provide and help me.

Regards

Mohammed Idrish M

If you have a lot of time on your hands, have at it.

Personally, http://www.callerid.com/index.php?page=whozz_calling_4_8

Planning on a little reverse engineering?

I think you're asking in the wrong group. Try alt.2600 or a pirate
group. This one is telecom tech not telecom engineering.

Carl, I guess the answer is no" Navarro
