Yes, I've seen that too with wire wrap terminations. -Hal CALIFORNIA PROPOSITION 65 WARNING: Some comments made by me are known to the State of California to cause irreversible brain damage and serious mental disorders leading to confinement.

I believe what changed this was the major fire in 1975 at The World Trade Center in New York City. A fire started at night on one of the floors and spread to the closet and ignited the cables. Cables burned from the 9th to the 19th floors causing over $2 million in damages. Alarms were delayed because the Trade Center did not have to comply with NYC building codes. There were no sprinklers and smoke detectors only in the air conditioning ducts,which did not activate because the ac was shut down for the night. I' m sure Arthur and Sam remember this fire.

I thought that the 1975 fire occurred within an NYT CO, not the World Trade Center. Ed Vaughn, MBSWWYPBX

Frame-type protectors (303 type, for example) can be ordered with stub cables up to 300 feet long for use in larger central offices. Ed Vaughn, MBSWWYPBX

I was there to see the "Monkey climb the pole." Talk about an amazing mechanical switching machine. I learned, very quickly, WHY jump suits were required. Rcaman Americom, Inc.

At $70 million ,one of the largest fire losses in the USA up to that time. That's the one that I remember. I lived in NJ at the time and I remember that even calling within my own CO in Westwood was severely hampered. I think I heard that they determined the cause of that fire to have been a cable maintenance technician performing a breakdown test on a faulty cable pair without clearing the ends first. I may be wrong, but that would make sense. Ed Vaughn, MBSWWYPBX

His sister remembers him heading to NY in the 70's from the Omaha Works. He passed a few months before I discovered this video, so I can't ask him about it. So sad to watch the work done in this video, and compare it to the response by Verizon to Sandy.
