We have a 2610 router with a T1 csu/dsu card which is connected through frame relay to our main office. We are only using 8 channels on the T1. I want to add a serial wic card for a RF controller. How will i configure the wic card to use the T1 csu/dsu bandwidth. The serial card needs to communciate to our main office. Could I setup certain channels for the WIC, thanks. Any configs will help.
