punch down 110 blocks

VIdeo shows how to setup, terminate, punch down, and make cross-connects on a 110 block.

110 blocks are frequently used as distribution for PBX stations and Telephone company. They have one major advantage over 66 blocks in that the connections are more densely concentrated. Therefore, they take up less space.

However, they do lack some of the versatility of 66 blocks. Even though 66 blocks are are larger, there are more ways to make cross connects. For instance you can connect two sets of wires to a Telco line on a 66-block. While on a 110, only one punch-down connection can be made per wire slot.

110 Blocks are like two layers. First layer is the source wiring (telephone lines or PBX ports) fanned out. Then 110 wafers are then punched-down on top of that using a multi-punch tool. Finally, wiring that feeds to inside connections (Station cabling, extended demarc) is punch down after that.

Usually the rear layer of wiring is from a telephone demarc. Then, the extended wiring (inside wiring) is punch on the outer connection.

I’m studying this for school right now. I learned more with this video than I did out of my book. Thank you.

Studying for my network + and this helped me understand a 110 block a little better. Thank you

As a Canadian, I have much more experience with BIX strips, rather than 110. In fact, I've only worked with 110 strips once. With BIX, instead of using those wafers, you punch the cable onto one edge of the strip and then flip it over, so the cable is at the back, leaving the front side open for the cross connects. BIX is common in Canada, because they originated with Nortel, the same company that made PBXs and a lot of other telecom gear. About 11.5 years ago, I was at the State Farm head office in Indianapolis, Illinois for training, where I was surprised to see lots of BIX, though they also had 110. The punches for BIX are very similar to 110, but the 110 punch can also be used with the Keystone connectors and patch panels. You can get BIX strips marked for different cable types, such as 25 pair, 4 pair and 2 pair. I don't recall seeing 3 pair, but they may exist to be used with the old 3 pair CAT3 phone cable. The only difference between the basic strips is the markers for cable type, but are electrically identical. There are also special types for multing, etc., but I haven't used those.

The sound of an impact tool hitting a 110 block is oddly satisfying.

Excellent video. Concise and answered every question I had about 110 blocks.

[makennadearborn]

So far, you're the best at making these visual aids I've seen. thanks a bunch!

[shanehinton]

Great tutorial! Way way back in the day I used to repair the KSU switch peripherals made by Nortel. I think I saw the bottom of one on your video. I watched your video as a refresher for 110 punch blocks.

Just did 4 of these last week for the speaker wire (18/2-18/4) at the two schools my companys running, I just double tap to avoid popping out wires, never thought to put the wafer on lmao just goes to show you in this field it's always a challenge and always room to grow! Happy punching!

Very helpful video! I also needed to learn how 110 was set up and this video saved my day! I had only punched down on already- installed 110 but the explanation and detail on the wafers helped so much. Thank you!

[kubatom]

Thanks for taking your time and explaining this clearly.

[stinkycheesecutter]

thanks for the video, im studying for an exam and this friendly video helped orient me to 110 blocks.

For cat6 you need to keep as many twists as possible to prevent crosstalk so don’t fan out the pairs. Just place them in the blocks by using the small peak of the block to separate the twist and place the pair before cutting.

This was rly helpful than a 74 slide from my class tnx man

Another student dropping in to thank you for explaining this more thoroughly than a college professor could (shocker, right?)

I'm wiring up an intercom system that requires 12 cable joints. Rather than using gel connectors floating in a large junction box, can you buy DIN rail terminals from which the connections can be made? That way they are neat and easy to understand for any future technician looking at them?

[Wardancer]

I used to do 600 pair cable with 110. (loved to do these)

[voiceofjeff]

Can 110 blocks be reused, like 66-blocks can? I have some old 110 blocks that I wouldn't mind putting into service on my home system (1A2 key system) but they have the wafers and I can't figure out how to get them off. Is it even possible? Or, should I just dump all of them?

[bdeem]

Great video! Needed to learn how a 110 block works in the immediate and this did not disappoint. I'm sure it wouldn't be recommended, but is it possible to rip pre-existing punches out of the wafers and repunch as needed and keep the physical integrity of the block/wafer?

[johncnorris]

A 110 block documentation / labeling video would be cool too!

[BIBOYWARRABOY]

is it possible to install the 110 block the same as 66 block horizontal or is it proper to install diagonal.. coz what i have now is a 110 block and the pabx that im working is all 66 block.. thanks
