This is a great forum.

I have some 554's, 2565's and a 2851, all 5 button phone sets. I am interested in acquiring a KSU and other associated equipment to set up a system in my home (a little side track to my SxS project). Would anybody be able to give me a description of what I would need to get this going (KSU, interrupter, power supply, etc) and sources for equipment?
