each remote has two DLCI's - one to the first T3, one to the second. you use load sharing to balance traffic across the links.
OR a couple of folks have suggested muxing multiple T3's at your host site. In the environment you describe, you should have no problem getting your telco to work with you. doing so would eliminate the need for two pvc's from each remote.
