Hmmm, I can see cross connecting an F1 to the F2 to your home/business,
but you would have to have a friend @ the CO to make anything of use on
it right?  Someone has to connect it to their frame in the CO, or
xconnect it to another F1 out??  If there is a telco with "live"
dialtone on F1 unprovisioned pairs, I would be shocked (or want to move
there :)  )
