[c-nsp] PA-POS-1OC3 vs. PA-A3-OC3SMI

[David Aldworth]

So the below config will get break the OC3 into DS3's but to get from  
each DS3 to the individual DS1's I need to add a TransMux card into  
the chassis. This would negate the need for the DS3's to be plugged  
into a VXR with a pa-mc-t3 card. Would one TransMux card be  
sufficient? What about for an OC12?
