Well, you can try to start with:

http://www.juniper.net/techpubs/software/junos/junos94/swconfig-network-interfaces/example-configuring-channelized-stm1-interfaces.html

Then eventually bundling multiple interfaces into multilink ppp, or
using EBGP multihop or EBGP multipath, but all three options
introduce enormous operational burden. And there are limitations.
Plus, your provider needs to support it + have clueful personnel to
help you in the middle of the night if that monster breaks.

If I were you I would rather consider using a normal STM1 interface
and a policer/rate-limit/CAR on the provider side. Mostly standard
setup nowadays and upgrade is a matter of minutes.
