Two phone lines give almost the same bandwith as a 128k isdn line, and at a fraction of the costs (especially when you don't have timed local psdn calls, and isdn calls are time-charged). One of our "remote" sites has four psdn lines going back to one of our (cisco/linux) servers, and the bandwidth is very impressive. The trick is to assign *identical* IP addresses for each link (ie, ppp0's IP = ppp1's IP, same remote IP at the server end of each link too). Set up a teql device, delete the default (or any) routes out of the box(es) that have ppp+ interfaces, bind the interfaces together using "tc qdisc", then set the outgoing default routes via the teql device (which is also given the same IP as the ppp+ interfaces). Sounds weird, but it works like magic.
