Does anyone have a recomendation on a good how-to reference for 66 block wiring strategies? Preferably something written with pictures.

The 66 block pages are 24~30/102

Wow, thank you very much.

That is a very informative document.

Thanks

smags, Welcome to our forum. I monitored some of your original questions in the general forum. You seem to have the ability to learn which is sometimes rare.

The previous link provided has excellent pictures for reference. I would like to touch on one thing for you to always remember. The value of the 66 block is that it will create a well organized and space conservative end to the many wires coming into the closet location. Once you have terminated those cables the pins on the 66 block will forever be the end of the pair. They will never get any shorter as long as no one gets foolish and thinks the only way to connect to a terminated pair is to pluck it off the block and twist on some other connection. That also explains the value of the use of jumper wire. Connect the jumper and a circuit is completed. Pull the jumper to make a change later on and you dispose of about a penny's worth of copper. Plus you create a length of only what is needed, no waste or consumption of valuable space. This is something you cannot accomplish with a patch panel and patch cables.

In you closet location you might have many cables that you have no idea where they go. It is a good idea to terminate them on a 66 block. They go somewhere and someday the ability to connect to one of them might come in handy.

Good Luck

Oh my goodness. This document is yet another case of a "professional" instructing aspiring professionals as to how things should be done. Aside from numerous typographical errors, there are contradictions all over the place.

"66 blocks should not be used for installations"? His illustration clearly shows a Suttle brand clear cover marked CAT5E. I have cases of them in stock, brand-new. True, with the illustrations shown, they are not CAT5/5e compliant, but the "over/under" method shown later is very much compliant.

"RJ45 is a typical Ethernet or LAN cable"....."Switches or hubs have female RJ45 jacks". There was never an RJ designation assigned for Ethernet/LAN wiring........never ever.

Later on, there is discussion regarding the "old USOC RJ" (registered jack) codes. He also refers to an "RJ11" as a one or two-line jack. Nope.

RJ11 is a 6P4C or 6P6C jack wired for only one line. An RJ14 is the same wired for two lines.

A 6P6C jack may have one, two or three lines wired to it, depending upon the application. The number of lines determines whether this piece of hardware is wired for RJ11, RJ14 or RJ25 service. By the way, there are lots of other "RJ" codes that can be associated with this jack, depending upon how it is wired.

An RJ45 never used more than pins 4, 5, 7 and 8, period. Quite a stretch from today's LAN configurations, huh? What's a LAN jack called that is wired for POE? "RJ46"? I think not.

These "professionals" are not sending the proper message, hence the entire industry today consisting of misnomers and errant information. While the general content of this document is good, it needs a lot of work in order to be accurate. Not bad for a basic learning tool, but that's about it.

Sorry, but today's "professionals" usually have no true experience in the modular jack concept that was originally formulated in the mid 1970's. They have just adapted their current ways, modified the original connectors' uses and developed their own terminology.

For those of you who know me, you probably feel that I have way too much time on my hands. I know that it would be easier to just roll over and play dead, but it bothers me when IT people have decided to step in and take over an entire industry based upon assumptions, bad advice and erroneous information.

The author is more than likely a representative of BICSI or a hardware manufacturer. Most of these people have no understanding of the USOC/RJ designation program and in most cases, many manufacturers of current hardware never even existed under these standards. Most current manufacturers of imported hardware have jumped upon the bandwagon of following the erroneous terminology. This further complicates newcomers' abilities to understand the true industry standards.

Deep breaths Ed, breath real deep. Coorsthirty is just around the corner. Good info Ed hope it takes this time.

thank you all. I have one question which is not really covered in this doc. I understand that on a 66 block (split) that all of the drops/permanent wiring get punched down to the outside clips. Here is dumb question #1, where does the incoming telco line typically get punched down (assume the incoming telco is CAT5e with 1 to 4 lines). Specifically which clips? I understand that once everything is punched down you can then wire jumper or use bridge clips utilizing the center clips to liven the drop lines. Also (dumb question #2) if there is only one live incoming pots line - Am I correct to assume that you punch down the other 3 pair anyway? #3, I read somewhere that the left side of the block is reserved for incoming telco and the right side is for the drops. Is this really standard practice? Seems like a waste of space to me on the left side if you only have one incoming CAT5e. OK I'm ready to get yelled at

While it can be done, using CAT5 to wire POTs lines is really overkill.

The cable used to deliver POTs lines to buildings is CAT0 so switching over to CAT5 really doesn't provide any benefits. The old familiar 2-pair cable will work quite nicely and is less expensive than 5 or 5E .

Your questions are hard to answer since you don't know if a phone system or just POTS lines are connecting to your station drops. Telco will either be looped to your drops for POTS or into the system.

Yes you punch down all station wiring.

Once again depends on what you're doing with the stations and the size of the project. On a small project not knowing if you'll have a system installed or just POTS lines I'd just terminate all stations on one side and jumper direct to equipment or loop pots and bridge clip. On a large known system install I'd terminated station cables on both sides of the block and jumper from the station equipment side of my system blocks. This is why you need to know what you're wiring it for.
