110 Wiring Blocks -- How to use them 1

[1Drisnil]

Maybe I missed this q/a on this, but as an IT Generalist familiar with Patch panels,dropping cable runs, and terminating Ethernet data jacks, how does one use 110 Wiring blocks? I've seen them used in network topologies but only as an illustration.

Could someone explain why they are used, how to actually use them, and what the IBP(industrial best practice) is ?

Do some Google searches you will find what you need.

Well here's my .02 Cents on 110 Blocks,
some companies like them because they use less space then a equalivant 66 Block, but it depends on the Application it's being used for, and how much space there is in the existing location, If you go to a number of manufactures Web sites like Siemon, Ortronics, Allentel,(just to name a few) you will find any Number of 110 related things, so when looking look for a specific Goal like 110 for Splicing/cross connect, 110 to modular plug RJ45/12 to help sort the "Trash from the Treasure"

Not sure what your question refers to.

Punch blocks such as 66 and 110 are typically used as crossconnect points.

Each cable terminates on a block and connections between cable made with jumper wire.

In the data arena in which you are familiar, this is done by terminating on patch panels and using patch cords.

I hope this helps

Where does the BIX block fit in here. The 66 blocks were ok for the old 1A and l0A key system. And 110 blocks never did impress me. Just my 2 cents worth.

110 punch blocks are terminated like you would terminate the back of a patch panel. The patch panel allows the user to plug and play, with the 110 block the patch cable is perminated connected. (Most manufactured make 110 patch cords that will allow you the plug and play option)

Bix and Krone are specific to thier manufactures.

 

[macphoneguy]

BIX blocks where made by 3M I think kind of a smaller version of a 110 block, and of course a different connection "tool" (but not modular like the standard patch panels of today)if you know what I mean, a typical install would likely not have them, (unless some vendor got a deal) They are usually seen inside ped's of the LEC,

 

[ISDNman]

I believe that Krone blocks have the ability to plug a cord in that breaks the two sides of the block and allows patching to either side (akin to pulling the jumpers on a split 66 block and then clipping on one side or the other.

Having read all the replies, I would edit my original post to ask how cross-connect blocks are used with horizontal "backbone" cable runs?

I understand that with Ethernet there is a 100m length limit.

 

[franklin97355]

Most data crossconnects are done with jumpers on a patch panel. 110 blocks are mainly used for voice grade circuits.

I use 110 to rj45 patch cables all the time for data!!

 

[newteky]

EIA/TIA 568B allows for a "Consolidation Point" in the data runs. This is probably what the illustrations you've seen are showing. Basically you would run data cables from patch panel to a 110 block. Then run to stations, basically adding a splice point.

If I ever used a block, I would put a cable right ontop of the other (not using any cross connect). Few points of termination the better.

Thanks for all the repies. Its been a while since I added any additional comments to this thread, but here goes...

I have come to understand the bigger picture. The rephrase the issues afore mentioned, the senario is this:

The 110 Blocks are in fact for use with voice grade circuits. My familarity with voice grade circuits have only been with 66 blocks; aside form the fact that most 110 blocks only allow for a pair of cables per "post", how to they differ from 66 blocks?

 

[Jtodd]

Other than appearence, and tool used to terminate, there really isn't a whole lot of difference. 66 Blocks do make it a little easier to bridge across terminations (ie from pair 1 to pair 26 using bridge clips), but this can be done with jumper wire.

Form is different, function is essentially the same. The form of the 110 blocks do make it easier to achieve higher electrical performance specifications, so you won't see any Cat6 66blocks. Though I do believe Siemon makes a Cat5e 66 block, but I wouldn't use it as there isn't a Cat5e patch cord to patch from the 66 to a switch, whereas there is for a 110 (even in the Cat6 relm as well).

working in the hospitality industry i am finding more and more high end customers who dont want to go to VOIP yet setting up like the following

they setup a patch panel on each floor for a section of rooms to use only 1 homerun 8 pair cable to the room for all phone jacks. then using a 100 pair cable, pulling it to the pbx room,terminates this to a 110 block for voice stations. this allows the hotel to save money now while they "feel" out the VOIP technology. they can later go back and change cabling around to fiber that already exists for high speed inernet connections when they are ready to go with the VOIP. i have seen a few new construction sites that the cabler uses a 2 to 1 adapter and patch cables to connect the multiple jacks to the cable going downstairs to pbx room. i have not seen a 110 block used for data connections directly though i have heard from other techs that they are used for short runs from a data closet to an office on the other side of the wall and dont want to place a patch panel there for 1 room(cost savings measure).

 

[Jtodd]

I don't particularly like it, and not for technical reasons, but 110 blocks have been used a lot around here for data runs.
(but no new ones since I've been here!)
Anyway, my issues are with patch cord routing and management. There are just a lot of issues with them when using 110 for data.
But you (telnettech) mentioned something, why would you need to go back and change cabling around after feeling out VoIP? And you don't NEED fiber for it in the horizontal. If you install the right stuff at the start, then you don't have to change anything later.
Maybe I didn't quite understand what you ment, so I might be missing something. But as an example, I've got 5 dorms on campus that to change from POT phones to VoIP, all I need to do is change patch cords on the voice blocks, add a few more switch ports, and add the required VoIP hardware, and it's done.
Anyway, what you describe just struck me, so I thought I'd elaborate a little.

the cable punched on back of the patch panel goes to the pbx room and is punched down onto a 110 block. later when they want to do VOIP you can route the calls to the network from the pbx and use subnets addresses for the phones in the rooms and you would connect to the fiber that has already been placed for the high speed internet for each room to the patch panel....the only thing is that the 100 pair cable is left there to future use....what that use is don't know yet(possibly cable television?)

HUH???????????????????????

 

[telnettech]

you

instead of using 110 blocks at the IDF closet on each floor, they use a patch panel....the top part of the patch panel is the station cables coming from the room jacks. the bottom part is the 100 pair cable going to the pbx room where it is punched down onto 110 blocks to be connected to the pbx.... they run a cat5 patch cable from the pbx part of the patch panel to the station part of the patch panel....they also have a section on the patch panel that feeds high speed internet service off their network to the rooms...this connection is fiber optic....later when they want to go to VOIP service, you take the station cables and change it around to be connected to the fiber optic part used for interneet service and connect to the patch panel part of the station. the Voice service comes across the network from the PBX. the orignal 100 pair that connected the patch panel to the PBX is useless now. ou can later use the cable for whatever you want....there is a technology that is being developed by the major Telcos that allows them to bring you television signals thru the phone lines...i dont know much about it but it was featured in a industry magazine named "america's telecommunications" may2005 issue

 

[youcandoit]

much better explanation..i understand now..still as jtodd mentioned you dont need fiber for stations for VoIP. as long as the station cables are cat 5 or better you're golden.
