Hello, I realize this is a really old thread and I'm not sure if this is the right place, but I was wondering if anyone had knowledge with this system.
I work for a small non-profit and the company that used to service our system went out of business several years ago. We have a DX2NA-32 system and everything works more or less fine, but I need to add an extension. I have some general networking knowledge but don't feel comfortable messing around with this set-up for fear I may break the whole system.
I've been looking through the manual that was linked above, but I'm still unsure terminology and what my steps would be. In addition to that all our phone lines go into a poorly labeled patch panel so I'm not even sure where to start or where I would hook it up in the first place.
If anyone was willing to help me that would be incredible. I have photos of everything as well.
