Teleco Question... More on my devious plan....

First, Thanks to all who have helped so far... I have some old modems (TRS-80, acoustic and etc.) which I would like to use (flashing LEDs are cool) so, I want to build a little telco emulator to interface with the modems in one of my Linux boxes. I figure an LM556 for the dial tone... A tone decoder for dialing... Not sure an easy way to decode pulse dialing. As for ring... I am thinking using two charged capacitors and switching them. That's the first method I came up with to limit the current cheaply. Any suggestions? I'd like to do this for less that $25.00. ---------------------------------------- Tired of Micro$oft???
