The best way to do this is to use inverse multiplexing multilink PPP. See the link below and scroll almost to the bottom for a configuration example. http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_ c/dcppp.htm It does't use dialer interfaces but does nice load balancing without killing the processor. "no ip route cache" is another alternative on both T1's but puts all packet in the process switched path and can really slam the router processor.
