What kind of connection does your ISP provide? Is it a tv cable, T1/E1,
T3/E3, or something else?
Make sure you take a good look at at least these things:
* protocols (hdlc, syncPPP, etc)
* in case of T1/T3/E1/E3: does it support fractional T1/T3/E1/E3
* connector type (V.35, RJ48, BNC, etc)
* driver support: open source drivers
The company I work for uses linux routers for E1 and T3 connections to our
upstream providers and customers. They work just fine...
