- I would like some help with a project I am working on. I am trying to buil
- d a circuit using a 68hc11e2 which will sense a phone ringing, pick up on n rin
- gs and then wait for a n digit code. Once correctly entered the user will get a
- new dial tone via the switching to another line. Are there any circuits all rea
- dy available to do such? Any ideas to this project I could use some help.
