Perhaps the best use is CYA. The Adtran CSU has an "Equipment Loss" and a "Net Loss" light.

If the T-1 Vendor goes down, and the customer calls me, I ask them to look at the Adtran and tell me what lights are on. It is always true that the "Net Loss" is on, I don't have to make a free service trip and there is a mark up on the Adtran.

I have lots of them used if anyone needs one.

Thanks, Bunnie
