The normal way for this is to have a wooden board where vendors (vz, etc)  
terminate their connections (demarc), and then you wire everything to your
rack, where you connect to your equipment.

Verizon will accept "110 block" or "66 block" for POTS dropoff. They won't 
terminate it on anything else. Get a "110 block" with a prewired 25-pair 
connector (amp rj-21x) and an AMP 25-pair patch panel (one jack=one pair) 
for distribution in a proper 19" rack.

You generally don't get a choice where cableco drops off your coax or puts 
cable modem, but you can try.

Generally, small business phone systems mount directly on that wooden
board, most of them are not rackmountable.

How many servers you going to have there? If its a large number, 
overheating can be a problem.

everything depends on how much money you want to spend on it.

you can get decent analog phone systems on ebay now for 500-1000$. If you
want pimp new IP phones, you might consider something else.

patch panels are 50-100$ a piece at most.

your biggest expense will be to clued people putting it all together. :)
