Hi Skarr,

Take an unused phone cord and cut one end off and strip the red & green wires. Connect them to your project on the incoming telephone line. When you are ready to test, plug the other end of the phone cord into a phone jack. I wouldn't worry about seizing the phone line at this point in your development.

In actuallity, to use line seizure properly you need to bring the outside incoming phone line to an RJ31X jack and then from there you bring the house phone side to the jack. The RJ31X jack has internal connections that maintain the phone line to house phones until you install the proper RJ45 plug into it. Then your equipment will have a DPDT relay that will maintain the connection until your project goes to call out.

Digest this and I'll get back to you tonight when I get back from work.

HTH,

BobK
