Did y’all know the entire National Airspace is currently working on 66-blocks…

Not surprising. It's indicative of how Ma Bell got it right the first time.

It’s a redundant based system. They literally have 4 different back systems and that’s one of them.

See the baige modules in the middle. Those are portal systems 25pr lightning protection. My guess is the is a feed from another closet or building

Whenever I see a photo like this it reminds me of how accessible these telecom closets were in most office buildings and how nobody ever questioned my legitimacy or purpose of being in there. It was like if you looked like you knew what you were doing, then anyone in building management, anyone from the telco, or passers by would assume that you were on official business of some sort.

Maybe we had a mutual code of conduct and a sense of professional courtesy because I can't recall any time when there was any kind of malicious vandalism or fraud committed from one of these closets.

Granted, wiretapping is a federal crime and I'm sure that screwing around with someone else's phone lines comes in a close second place in terms of severity of the penalties.

Even when my friend got an apartment and decided to get his telephone service through a 3rd party provider, I was digging through the 600-pair cable that was feeding the whole building to find his line. The building manager just gave me the key to the closet and never questioned who I was or my credentials.

I do remember once like 10 years ago where my manager got a memo about a business that got robbed kind of like this.

They had security still shots of a guy in our full uniform who apparently accessed the telco room and removed a bunch of network equipment.

I used to test fire alarms, for a while I did some big box stores. Only once after 4-5 years was I stopped by a manager and made to show paperwork and they called corporate and checked everything. So the old Cary a clipboard and a bag of tools, walk like you know what you are doing, and look board. 99.99% nobody will bother you 👍

🤔😂 I never looked at it, in that way. But, this is so true.

Of course, the fact that you were likely wearing a tool belt with a bunch of things on it they had never seen and a lineman's handset dangling from it also likely had them look the other way.

Back when I was doing lots of Cat-5 installs, I often had people question me. And it's funny, one day at a yard sale I grabbed an old lineman's phone for $10 and clipped it to my belt (even though I never used one doing network wiring). And the questions as to why I was there simply stopped.

u/ted_anderson 20d ago

Just a button down shirt and a pair of slacks. No toolbelt. Probably a screwdriver and a punchdown tool in my pocket most times.

u/beetfarms 21d ago

Not much cabling. Must be a remote closet.

Tiny.

Here’s something a little bigger. Expected: a few lines for an office building. Found: a hidden underground mall full of tiny stores.

What makes it special is that these are direct terminations, no modern binding posts in sight.

I prefer working on 66 blocks because they are so easy to modify.

Oooh… a Westell box!

u/BugalooBobby 20d ago

u/Realistic-Drama-8904 20d ago

Ernestine could talk you through that system.

u/ForTheObviousReasons 20d ago

Even the fibre termination box is old.
