i have a customer that wants to hook up a 2000 to a 200 va t1 to do all there intercom calls from one state to another just need to know if this can be done with these two switchs.

Yes it can over a point to point T1 . You must have digital links available in both pbx's and the correct options purchased for the system software . The msdn/dpnss intergration is one of the best on the market .

If the 200 is an analog 200 you are SOL !

Hi, Do you know where I can obtain an INSTALLER'S MANUAL for the SX-200D PBX? I went to the website and found the user guides, but I need installation reqs and configuration. Please let me know if you can help.
Thanks,

This site may have them . They charge a fair price ! Other than that , I can't help ya on Manuals ! Also your profile needs a little expanding . Thanks

I was Wrong when I posted Sundance may have manuals for the 200D . My mistake , sorry
