I have the chance to get my hands on a couple of routers to build a home lab. I can get a 1841-T1 or an 1811/K9 - at a reasonable cost! The former has a CSD/DSU for T1 that is of no use to me at this point (at least is is modular and I may be able to use it elsewhere). From what I have read it has built in ethernet ports that are there to replace a WIC-1ENET interface card to give you wan connectivity via broadband, i.e. cable. These I should be able to config as interfaces in the OS. Since I have not worked with these units is this a correct assumption?
