Here is something I've never seen or heard of before. Just bought a 2565 that had a 760 and 666 wired into it. Of course I hooked it up and it didn't work. I know, it needs a Model 55 control unit to work, but I thought maybe the 760 and 666 were wired into a terminal board inside the phone and used the spare leads from the 25-pair cable, so the Model 55 control unit could be mounted by the KSU. Imagine my surprise when I opened the phone up and found all the wires from the 760 and 666 wired into the chassis of the 2565. Has anyone else seen anything like this? Your thoughts would be appreciated.
