It's depressingly simple. Take a piece of Velcro that's too short to be useful for bundling cables, ideally one that is a different colour from the normal one used where you work. Stash it in your pocket. When you need to trace a wire, wrap it around that wire, and push/pull it along the length. If you meet an obstruction you just figure out where it is on the other side and re-attach it there. For poo poo like tracing fibre up through cab roofs and along trays of hundreds of identical yellow cables it's a lifesaver.

This is how I learned that the floor to floor riser panels are literally just cabled together through a hole someone punched into the concrete floor, and that you can actually fall through if you trust the underfloor cable trays to be correctly bolted together.

Has someone made a poor-man's ladder tray by zip tying some short lengths of pipe to another pipe? Also my opinion on punch blocks is Krone supremacy.

suuma posted:I'm a support nerd, can somebody explain what this is? It's BIX block. Similar to 110 block, but it's more common in Canada because it was Nortel's standard forever. It's basically a patch panel for wire pairs. If you have digital phones in your building then chances are there's a bunch of blocks of this type of stuff in a closet somewhere. It's mostly used for digital and analog telephony but you will occasionally see ethernet patch panels using it too. I do a lot of work installing and servicing business phone systems. It's moving towards IP phones, which are way easier to work with because all you care about is that it has power and an ethernet connection. With digital phone systems, every wall jack gets connected to a specific port on the phone system which is programmed for a certain extension. So if you're installing a new phone system using existing cabling, you have to know where on the punchdown block the wire pair for each specific wall jack comes out. If you're very lucky, whoever cabled it in the first place decades ago actually labeled poo poo, and the labeling has been kept legible and up to date. You are never that lucky, which is why you need one of these: https://www.amazon.ca/Fluke-Networks-26000900-Pro3000-Generator/dp/B000FTADX0 Thanks Ants posted:Has someone made a poor-man's ladder tray by zip tying some short lengths of pipe to another pipe? I think the "ladder" was just meant to keep loose piping / cabling off the bare dirt floor. I've never worked with Krone, but gently caress 66-block forever.

Is it Bix or Krone where the standard punch tool actually has a slicing cutter? I don't do traditional telephony, only data, but that tool was super neat.

I somehow have a genuine ADC-made tool and it's so much nicer than the cheap versions. You can decide whether you want it to cut or not, and it has an interlock so it won't cut the wire unless it punched it down properly. The whole Krone range is so ridiculously German.

I'm going to ask a dumb question because I've never been taught or met anyone who actually knows: is there a trick to using those network flukes effectively? I can never get a positive result. I have a site which used to be 2 sites, they built a road between them and joined them up (essentially) On one side, I have krone strips which go to patch panels in data cabs, so patching is really easy. The other site has exactly what you describe where every wall jack is an assigned socket and nothing is labelled. In the 4 years I've been here I've sussed all the important ones, but it would be nice to get the fluke working right

For my sins I do occasional punch down stuff, I have a collection of different 'krone' tools, some work better on some panels than others, so I mix and match: Mostly I just do patch panel stuff now though, and even that, thankfully not very often.

Usually I don't get a solid tone unless I practically have the probe right on top of the wire. However, I will say I don't have a Fluke toner. I remember having a Fluke cable tester waaaay back when I did network engineering and that was the poo poo.

gently caress punching down anything ever. I recently moved into a new house and as part of a bunch of electrical work I was having cat5 pulled from various parts of the house back to a panel next to my cabinet in the garage. When we were doing the walkthrough and talking about termination I showed him the leviton panel I’d already screwed into the wall. He says, “And who will punch them down? You?” I say, “No, I’ll leave that for you guys to do.” A beat. “...Okay.” We had about ten thousand dollars of electrical work going into the house and I could tell that punching cat5 was this —-><—- close to being a deal breaker. No one wants to do it. I pay people to do my plumbing. I pay people to do my landscaping. I pay people to do my punch-downs.

Funny part is that after the job was done the electrician left his cable crimping tool and punch down tool behind. I thought, “great! Now I have the tools to do it myself.” I called him up and told him he left his tools behind.

I still have one of these sitting in my network tool bag. The last time I used it was when I replaced all the cat5 with cat6 when I moved in 8 years ago. Just slam 4 pair at once. With a reversible blade if you don't need/want to cut. It works fantastically. It says it can do up to 5 pair, but I've only ever done ethernet cabling.

With the proper tools punching is easy and painless. I'd rather spend my afternoon punching a couple hundred wires into blocks than trying to line up 8 little wires in the right order 30 times to crimp ends onto cable runs.
