I would purchase a Partner system from AT&T / Lucent / Avaya.  I think 
they are both analog and digital.  The analog will work for modems.  You 
will likely need a digital set with display to program things.

I should clarify, /each/ line is both digital and analog.  This is nicer 
than older Nortel Norstar systems that I've worked with which needed 
additional equipment equipment, Analog Terminal Adapter, as they were 
(by default) purely digital lines.

Note:  You might not be able to get anything faster than 33.6 without 
some more effort and / or more specialized phone equipment.

There's always the VoIP route, but that's an even deeper, darker, 
steeper, and more slippery rabbit hole.

Partner systems will likely be 8 analog lines that can be used in short 

My biggest concern with a Partner system would be the dial plan.  As in, 
will the modems, or other communications applications be okay with a two 
digit phone number?  Or do you need to make the phone system use longer 
phone numbers.  (As I type this, I seem to remember Nortel systems 
having an option.  I bet Partner systems do too.)  I'd cross this 
particular bridge when you get there, if you get there.
