James,

If they are transporting your VLAN's perfectly then there shouldn't be an
issue..   what ever you inject into 320 shouldn't be messed with.

But, you would have to be injecting those other vlans into 320 before you
send it down the trunk.  This is something you have to do, not them.

I assume someone else will correct me if I am wrong.
