Joe,
I once had to go to an office where they had a problem and when I got there the first place I looked was on the frame where they connect the outside cables to the computers LEN. There was no wire there so I got the woman who was supposed to do that and showed her the terminals and told her to run the x-connect. She informed me she wasn't going to do anything as her computer said it was in. One of the two times that I ever got really mad and said anything to any of the people that worked for the companies. I told her I was tired, had flown hundreds of miles without any sleep to find that she hadn't did her job and I didn't give a dam what her computer said, if she didn't have that wire in within the next minute her computer and her would both be out in the parking lot. She put it in and the problem was solved.
