I'm curious about BA DACS. I don't know if this is standard, but they are the only telco who has also told me "we put a loop up on the DACS, but sometimes it doesn't work ... so don't assume that it is a valid test." And I have witnessed that same happening. If you can't create a simple maintenance loop on BA's DACS, their choice of vendors does seem questionable. -travis On 16 May 2000, Sean Donelan wrote:
Bell Atlantic lost another DACS yesterday taking out 280 T3s for 3-1/2 hours in the northeastern corridor and New York City.
I'm not a transmission person, but what is the problem with DACS? Why do these "highly reliable" systems fail in such catastrophic ways?
