This is not good. Granted, This DS3 is one of 4 private interconnect BBN has to MCI. I don't think there's anything wrong with it's current provisioning given that their other backbone DS3 have diverse routing..

This is not good. Granted, most DS-3 microwave radios have hot standby radios, muldems ect. on each end but, they are always ripe for outage due to interference or path fade. I can see the microwave as a segment of a SONET OC-3 link, only if the other side is fiber. > Some of their backbone T-3's > come into a Pac Bell OC-48, which has an entirely seperate protection > path into Stanford itself (Stanford alltogether has two Pac Bell OC-48's, > with a third one planned!).
