Multiple point to point t1s

I have 6 customers that I need to deliver point to point t1 lines to
from our data center. I am posting in hopes that someone on this list
can guide me in the proper direction in regards to what hardware would
be best to use. Currently I have a single point to point connection
using a single router with csu/dsu on both ends. What would be the best
way to terminate the other t1s at our data center ..
