Anyone familiar with a 3Com NBX100 VOIP system?

[StingMe]

I've been asked to find a new home for a 3Com NBX 100 VOIP system (communications center, analog converter, and phones) - is there any way to get the system up and running to test without a "live" line or service? The system was working when removed from a now defunct small office (yet another victim of the down economy) but I'd like to try to confirm its status. Do I need to use a WinPC to interact with the NBX?

I'll have to break out a manual and do some searching online to figure out exactly what I've got but any guidance will be greatly appreciated - thanks!

The system basically looks like this one: http://voipproducts.com/wp-content/uploa...051061.jpg
