The author is more than likely a representative of BICSI or a hardware manufacturer.

Dunno about that but I do know that he is a sparkie. I actually complemented him on that (and he was grateful that the compliment was coming from me) over at Mike Holt's sparkie board when he provided it for them to read. I introduced it here, mainly for critique. True, there are lots of things we see that should be changed but I figure it's the closest thing they have to a text on the subject. If the sparkies read and understand one quarter of it, even with the errors they will be better off than what they are now.

The documents value is that there are pictures to refer to. As far as the terminology references I must admit I never read them. The reason being that I remember it being posted in the other location and I even remember Hal being complimented on it. Since it was created by a sparkie I only valued it as a source of quality photography, not quality technical information.

Now as far as the questions from smags.

Terminating all pairs of station cables to 66 blocks in the selected central location is done to have continued access to the ends without damaging the integrity of the building infrastructure.

The connection of CO lines to station cables can't be answered in the generic sense like the station cables can. That is a question requiring more information that is specific to the location.

"What's a LAN jack called that is wired for POE? "RJ46"?"

Ed,

I love it! I think we should all start using this in quotes so it totally confuses the sparkies and the CGs. Call it the latest standard for POE wiring and if you don't knwo what it is - well then you obviously are not qualified to bid onthis job

Ed, the poster asked for a reco on a good how-to, with pics and that's where I directed them. I know it's full of typo's and terminology errors, but I wasn't posting it for any other reason than the request of the original post. I actually came across that book thanks to Hal, and have referred many people to it for exactly what it is... a quick, 102 page, Telephone & Data Introduction, with pictures. I didn't mean to ruffle your feathers.

Mr. Smags:

The CO lines are generally terminated on a separate dedicated 66M50 block. The pairs can be "multipled" along the left side (Row 1) to provide several (multiple) appearances of the same telephone number(s).

Start at the top, and using the loop-through method (punch-down tool turned with the non-cutting blade exposed) make several appearances, going down Row 1. The number of multiples for each of the 4 pairs is dependent upon whether the job calls for all CO lines to appear every where (non-KSU phones) or whether the lines will be cross-connected to a KSU. I generally assume that I will need several appearances of each line, even using a KSU. That's because some lines may need to be wired to external bells, answering machines, fax machines, credit card terminals, etc etc etc.

With the 66 block, and 4 incoming lines, you can get 6 sets of pins on Row 1 for each line (4 x 6 = 24) and then use bridging clips to carry the lines over to row 4, where you will cut down the cross-connections. The bridging clips are used to open each appearance, one at a time, for trouble-shooting.

Label the block "CO Feeds" and then put the circuit numbers on a piece of paper (called the "brain") and leave a copy in the back of the 89B bracket, and a copy in your file cabinet at the office, for future reference. The brain should consist of several pieces of paper, each with the assignments of each 66 block.

Don't go to any job with the original copy of the brain...always make a photocopy to take with you before leaving the office. I have OCD and AHHD, so I speak from experience that someday you will lose your brain, and having the original safe in the file cabinet will save you.

Where's the BIX??

Skip....

Just goes to prove that BIX is becoming more & more popular. It's catching on all over the world!

BTW, I don't remember ANY "How To" thread on this board for BIX. Must mean that it's simple & effecient to use. Then again, maybe only Canadians are skilled enough to use them.

you might be on to something Dave , if we all switched to BIX can you imagine the sparky s and CG's trying to figure what to do ?

Or maybe they are the only ones that have the spare time to waste! Wait, I'll have time starting next week! Anything is better than cleaning out the garage. Well, maybe not. Gotta think about that for a while. I'll get back to you in a week or so. John C. (Not Garand)
