I have a cisco 2514 router with a V.35 connection to an adtran ISU 128. I am using this as a dialup ppp connection to the Internet for a small office network. Is it possible to use each b channel seperately - By that I mean can I make 2 indenpendent calls to different numbers. I would like to be able to use one channel for an Internet connection and one channel to dialup to my corporate network.
