[ANSS-netops] Trillium Compact installation

[David S. Croker]

Hi All,

Simple question with a potentially longwinded answer (simple answer 
preferred):  What kind of vault installation do you do for permanent 
Trillium Compact sites?  Full-blown vaults with lots of insulation, 
slightly reduced scale vaults with a little less insulation, or 
simple small scale tubes buried a couple feet down with minor 
insulation?  How do they respond to temperature changes?

Thanks for any insight you might have.

Dave
