My grandfather recently gave me his old phone system from his office, i know it works. The Nortel People took it out when they put the new system in. I know almost nothing about this thing but need to get it working for my dads office. I know it has the main unit and the Expansion Unit. It also has this thing with two sets of pins sticking up in a long row. i need to know how to hook it all up and then program it!!!


PLEASE HELP ME!!!!!!!!!!
