Question : Problem: Binding 2 T1's on a Cisco 2600 Router

Hey there!
     We have an office with 2 T1's but one is not being used at the moment. I'd like to bind it with the one that's currently in use. We have a Cisco 2600 router currently in that office. Now, the two T1's are from different carriers ... the one in use has a /30 IP block and the "dormant" one has a /29. Does any of this pose a problem? Thanks.

You have some options, none of them include 'binding' the two together because they are different providers. Only if they are the same provider and they support it.
You can load-share between them, but the techniques to do so vary according to your requirements and each technique has its own risks and rewards.
Rather than go on with a bunch of options, have a read through these, and then we can get into more specifics on what you want to accomplish:
