If you want more DS3 ports, for N x DS3, perhaps an Overture ISG-2200  
or ISG-5000:

http://www.overturenetworks.com/products/isg_5000.htm

Both are "modular" chassis.  The 2200 supports 1 "option slot" you can  
install a 3-port DS3 card into to start with, then later pull it out  
an insert a 1-port OC-3c into.  The 5000 is a 4-slot chassis.  Both  
chassis work with the same modules.
