[c-nsp] Assurared BW to customer

Seems safer to purchase two clear channel circuits, one from each provider.
 In the event that a single provider goes down the interface/neighbor will
fail and normal routing failover will occur.  Even with the redundant
providers the aggregated GE must still plug into a single card on a single
piece of equipment.  Maybe I'm missing something, but it seems like you
traded one single point of failure for another.
