     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.



                                                  Alex Jeannopoulos
