Needle/Haystack
The worst documented piece of technology we have at our organization is the phone system, or rather, the analog piece of it. In our older buildings, there is miles of twisted pair copper, numerous 66 and 110 blocks, and sparse documentation or labeling on anything. Thankfully, the bulk of it is dead, the remainder of multiple phone systems of the past.
Now, 99.9% of our handsets are cisco VoIP phones. We still have POTS lines dedicated to fire, burglar, fax, and who knows what else. The “who knows what else” is the problem I have. There’s spotty documentation on what each POTS line is for, and due to many interconnected blocks spread out throughout every building, it’s difficult to determine where these lines go to from the demarc. The most frustrating part is, out facilities department can’t tell me what equipment they even use that pulls dial tone.
At least with email systems and directory services you can sort of put a complete picture together of your servers, or using your routing tables and cisco network assistant (if you’re on cisco gear) you can put together a map of your network starting with no documentation. Old twisted pair phone cabling is like the wild west.
Any other system or network admins out there have to deal with spaghetti soup legacy phone systems?
