If you're after a "front end" to connect to your uP , have a look at some standard pc modems...
On some of them it is possible to "saw" around the transformer and "off hook optocoupler" , so you end up with a nice little board that is easy to work with. Try to avoid the super cheap software modems as they often use a capacitor to connect to the line ,instead of a transformer. |
