since this circuit only used 1 E1, i removed the IMA
config and placed the pvc config under a subinterface
on the physical atm interface and everything started
working.
thanks for the responses and assistance!

Thanks for pointing out the bug Tao but we are unable to pass traffic
which is inconsistent with the bug description.
Here is the config on the 3640 router followed by some show commands

Subject: Re: ATM troubles
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. "
