Why do you have those VBR settings I think you need to change your MBS to 32, 6
4 etc.

Excerpt from Cisco:
"Before Cisco IOS. Software Release 12.0(11)S and 12.1(3)E, ATM physical
interfaces configured as a member of an IMA group could have a "line
protocol is down" status even though the IMA interface was up/up and passed
traffic without any problems. This state could occur on the Cisco 7200
router series because the ATM interfaces are the raw links, and all
protocol-related configuration is done on the virtual IMA interface. Cisco
Bug ID CSCdr22203 changed this default behavior on the 7200 router. On the
7500 and 3600 series, the line protocol status on the ATM physical
interfaces is brought up when the links are operational. "
