110 Block Punching Down 25 pair Cable

Showing how to punch down a 25 pair cable on a 110 block. When punching down a 25 pair its important to get the color code correct. I have a video on the color code. Always lead with the tip color and follow the order weather you are punching down a 25 pair or 100 pair.
This is the second video in my Tel-Comm series be on the look out for more of these videos as I will be creating a playlist for them soon.

Now you can do BIX strips. Living in Canada, I've come across far more BIX strips than 110. In fact, I've only once come across a 110 strip in my work. Also, 66 blocks are getting scarce and I haven't seen one in many years. You use a similar punch tool for BIX, but not those clips. With BIX, you punch down the cable on one side of the strip and then flip it over, so that the cross connect side is exposed. I carry both BIX and 110 punches in my tool kit, but these days I mainly use the 110 for Ethernet connectors and BIX is used less with the move of just about everything to IP/Ethernet. BTW, my cross connect experience goes back over 50 years to the days of "Christmas tree" solder blocks and wire wrap blocks.

Nice job. Taking my BICSI lass next week and this helps much. I am in Timing and Sync so don't see much of this but need it to fill out my experience.

[@allanrobichaud1972]

I too am here because I am taking a BICSI hands on exam next week. How did you do?

[@kalempolanco782]

Thanks, you are very good

[@Stiffarmyaya99]

My favorite!!!!

[@harshdoshi8947]

can you please tell me how many connecting blocks are needed?

[@luckybaby8148]

Depends on your cable size and how many of those pairs you actually need to use. Also, 110 blocks come in different configurations (50-pair, 100-pair, 300-pair...) If you're referring to the C4 clip, a single 50-pair 110 block will need 12 clips.

Thank you!

Nice bro.

[@mahboobnasimi3280]

Well explained Sir will you explain what's this punching down and how it helps us? Is this important for a network engineer to understand ? Tnx

I know this comment is 6 months old, but I'm going to answer in case others want to know in the future. This video shows what would typically be a part of a "Cross-Connect". The 66-block is terminating an incoming cable (it could be an outside cable, but it could be one from inside the same building) on the left side. These could be used for POTS (old telephone) lines at this point. Then on the right side of the 66-block, you will have an indoor cable (in this case a 25-pair cable) punched down. That 25-pair then goes to the 110 block (it could also go to a punch-down style patch panel in a rack). This allows it to be easily connected to a 4-pair patch cable (like cat6) for data transfer. For a Network Engineer, knowing that there is a cross connect in this location, which cables are connected and what those cables feed could be important when you are troubleshooting a fault. You will also be able to tell how many pairs are available for new phone or data usage.

I love your videos"

[@NotABushFan1]

your cable color code is great, easy. some cable only has solid colors, so the white blue pair has a solid white and a solid blue, then the white orange pair has a solid white and solid orange. much care is needed to make sure you do not mix up the pairs.

[@James_Knott]

Yeah, I don't care for that type of cable either. Also, there are some makes where it's hard to tell the blue and green apart.
