[c-nsp] 12.2 -> 12.2S upgrade and PA-2T3+ problem

[Brian Feeny]

Rodney,

it turned out to be a very strange situation.

The IOS I don't believe was the problem, even though I did revert back. 
  I will redo the upgrade
at a later time.  What happened, is we had a maintenance window, and I 
was upgrading all kinds of
stuff.  So things were down........down legitimately, because of 
maintenance.  ATT saw this, and thought
something was wrong, and so thru a circuit of ours into "testing".  
When I was done and looked at everything
I noticed ATT was down.  Yet the config was the same.  All I had done 
was upgrade IOS, and I knew the odds
of ATT having a problem coincidently at the same time I did an upgrade 
was small.  So in short, I dont believe
there was an IOS issue, just ATT not talking to me before doing testing 
on a circuit that was down.
