One note on this :-)..
Some time ago,  a friend of mine worked in a carrier that had dialup modems for out-of-band access ('lights-out, end-of-world' recovery)
They kept the practice in a new NGN Class4/5 replacement..

Often having something like an ADSL like connection will save trips to colo and will give you nice abilities to work on stuff when combined with serial management tools.
