I happen to know someone
that drilled thru a coax that was being used as a network backbone while drilling a hole for it's fiber replacement.
The weapon of choice:
The users never missed a beat, probably because they were out to lunch long enough after it happened to devise the crafty repair.
Rest assured, a week later the fiber went live and I have slept well ever since.
As for the guy trying to bridge two digital phones on one switch port, he did do the right thing and admit he was in over his head.
It seemed like he thought it was like wiring a second line in a residence and it hit him that he was in too deep when he saw another phone that had 5 line appearances on it.
You have to admit though, it would have been priceless if the thread started out with someone looking for a source for a replacement card for the switch and installation instructions.
