You'll probably want to look into creating a Dundi cluster.  I would
not recommend putting more than two Quad span T1 cards in a single
machine.  Actually, I probably wouldn't put more than one in a single
machine.

If you use 3 Quad PRI cards each one in a different machine and
configure those 3 machines as a Dundi cluster, you should be able to
fulfill your 10PRI / 300 channel requirement.  You might want to
consider even five, six, or more machines.  It would certainly reduce
the impact of a hardware failure.
