Obviously you cannot put 16 E1s on a single server.  And at least in the 
US, getting 16 T1s makes no sense.  It costs just as much as a T3 (28 T1s)

You can do it, I would inquire about an E3 (I suppose there has to be 
such a thing).  A T3 comes as two coaxial cables, one send, on receive 
and would attach to a MUX to break out your E1s.

Seven servers should do the trick.
