Temporary Routing/Switching backup with Backplane and multiple switch cards...

[Martes G Wigglesworth]

I was wondering if anyone else has attempted to compliment their routing 
devices or switching devices with a back-plane and multiple switch cards or 
E1/T1 cards with any success? Meaning that it was worth the trouble to build.

This seems a bit useless initially, however, I am doing some research into 
this for quick-fix disaster recovery systems in case the 3800s are down, 
etc...   A bit home-grown, but would like to know if the design idea would be 
viable and not just a costly home-grown project...  Maybe for a small point of 
present in a wireless environment which has multiple E1/T1 drops to terminate 
for back-haul transfer central management stations, etc...
