Glen, I take a look whether we (BHN) have any internal statistics for outages and their root causes … If so, I might be able to bring in some data for the next meeting, if it is cleared by legal. I am sure other operators also keep track of such statistics … Regards Marek From: Glen Kramer [mailto:gkramer@xxxxxxxxxxxx] All, Please see response from Victor. Does anyone know of any FCC Network Reliability task force publications on this? Glen From: Victor Hou Glen, Yes, I wrote that paper. The work was continued at Bellcore/Telcordia. But when the FCC set up a Network Reliability task force in the mid-1990s, I am not sure if some of the outage reporting was taken over by other procedures. I wrote only one public paper on that study, and a colleague of mine (Samuel Lisle) took the study over and may have published additional papers. So, I do not know how much longer Bellcore continued that study. Obviously, data from that paper is 24 years old now, and I would assume the telco/cable industry does a better job at outage prevention, especially dig-ups.

If yes, do you know if there is any updated info on fiber failure rates? Glen |
