I'm curious to find out if there is a device that would allow a single DS3 to terminate on two different routers, and switch from the primary to the backup router if the primary were to fail. I've seen this for T1 circuits but I can't find anything for DS3.
I'd bet you could make something workable with a DPDT coaxial relay, driving it from alarm contacts or a relay output of whatever monitoring system you might already have. The tricky part would probably be appropriately defining "failure" in order to get it to automatically switch at the right time without causing more problems than you started with. http://www.rfparts.com/coaxial.html -- -Will :: AD6XL Orton :: http://www.loopfree.net/
