OCx cards are all "channelized".  It all depends on the circuits you
want to build on them and whether or not they are concatinated or not.

That's all SONET switching.  You can't do two OC3c's and merge them into
one large OC12c, but you can delivery two OC3c's on six STS's on the OC12.

You can use any OC3 or OC12 card, or any of the new MRC's.  You won't be
using IR for 70KM, you'll be using 1550nm ELR cards.
