There's two possibilities here:

a) You're running a channelized STM-1 PIC, which can get you
   n x E1 logical circuits.

b) You're running a clear-channel STM-1 PIC, and your
   upstream will likely use policing to limit your bandwidth
   to/from them to 2Mbps increments, or as your contract
   permits.

I'd recommend the latter, less configuration hassle given 
the application.

Channelized STM-1 makes more sense for customer PE-side 
customer aggregation in n x E1 increments.

Cheers,

Mark.
