We’re inheriting a site with a bit of an odd setup. When I look at it, all my instincts scream it’s wrong. It’s not big, 30 ports or so.
They are all cat5e lines, paired white and blue which implies a data/voice network is what was originally planned. However all 30 lines are directly terminated into a bix panel, then run as individual twisted pairs for about a ft, then patched back into another bix block whose cat 5 cables serve as patch cables to the switch about 10ft away.
Now, some of these are obviously for their old pots system which is fine, but why would anyone add two extra splices into their data lines like that? Especially when they could just mount the switch beside the bix blocks.
I have a cable certifier on the way to validate my concerns. I’m guessing I’m going to see reflections on the line at those splices along with an unacceptable crosstalk. Am I wrong? I’ve never seen this even on large municipal networks.
Also I couldn’t find any info in my search, should I expect an issue from these data lines run to modular jacks in the wall as they are moulded/stamped as isdn connectors? I assume no unless I’m trying to pass a cat6 cert on that line?
