I have to admitt his has been an adventure. Been wanting to conenct up some 1a2 phones to a home phone experiment which consists of an Asterisk pbx, some ata adapters giving 4 lines and the regular incomming phone line. There's a few phones floating around my garage to play with. Also have a 620 , 8 line unit and a power supply but no interrupter. No manuals or schematics, but I am going to try and hook it all up sometime. Interesting to see that I am not the only one trying to do this!
