The easiest and most cost effective option for a 7200 series is an 
Adtran Opti-3 OC3-DS3 mux. It is available with one controller card 
(unprotected) or two (protected) and will give you three DS3s via BNC 
connectors on the back. It is -48VDC power, but you can buy two 
little 1A -48VDC power supplies from Adtran if you don't have -48VDC 
at your POP. The box is 1U and they are rock solid reliable and can 
be found new for $3k to $4k. You will also need PA-MC-T3 or PA-MC-2T3 
cards to break down the DS3s into T1s. We use this solution all over 
the US and it works great.
