Wiring 1

[DaveThePhoneDoctorLV]

I am interested in what your opinion is regarding wiring within the cavity of walls and ceilings.

I am reviewing my states construction and fire laws regarding different types of voice and data wiring and installation of jack and outlets.

What are thoughts regarding this. Do you insist on conduit for all your installation or do you simply run surface mounted and ceiling cable etc..

even IP capable systems have sometimes still digital sets (or analog) connected and then they need 1 pair (usually) but still might have an RJ45 cable to plug in but only utilize pin 4/5 to connect.

insanity is just a state of mind

the proper way to do TDM voice connection is not to use 568a/b
jacks but to use 4 or 6 position voice grade jacks it stops people from plugging network cables in the wrong place...

I agree with cwc3, on this one. That is the way I have always done phone jacks (4 & 6pin 6pos modular jacks) and data jacks (568B), separately!

I'm in there with cwc3 too. I am using CAT5 now for all my cabling just in case down the road something has to change, but I'm only putting 6-wire USOC modules on the end to prevent the idiots I work with from plugging computers into the phone jacks. We also use orange CAT5 for the data and almond or white 6-wire jacks for the voice so it's easier when planning a project for a customer to ask them how many white jacks there are and how many orange. Then we don't have to drive to the site just to determine if more drops are needed. I figure the cost between CAT3 and CAT5 is not huge, and since in many cases - at least in the new construction - voice and data IDFs are in close proximity, if it ever becomes necessary to change a voice line over to IP all I have to do is slap on a CAT5 and move the cable over to the data rack. I do use blue for data and gray for voice as well so we can tell them apart in the ceiling.

People know that if they see a cable that's a different color (green is CAT6 for imaging, Yellow is nurse call, Red is fire/security, etc) they know to ask someone. Same goes for module colors. If the color isn't right they will ask someone. We've used white/almond for voice, orange for CAT5 data, green for CAT6 data, red for satellite-based dialtone, blue for ISDN BRI, and black for special purposes (a crappy communication system called Omninote that injects RF into the building wiring that I refuse to let coexist with my voice infrastructure).

There's a few ideas from my neck of the woods...

 

[Mugsiensedgwick]

I utilize 8 pin jacks for everything and never have had a problem.
I am the tech is a medium sized hospital.
My thinking is that I may want to turn up more phones on a moments notice into the jack location. Eight conductors to work with and a homemade splitter biscuit gets it done in a hurry.
Just another perspective on this question. Benefits both ways.

For cat 5 you allways connect all 9 wires from the floor socket to the patch pannel otherwise it is not cat 5. it is a custome wireing schem that will cause problemms & additional cost should the customer move to someone who does not know how it is configured.

 

[IPGuru]

that should read 8 wires (fat finger syndrome strikes again)

 

[cwc3]

to expand on my post on voice jacks since my digital ports
pin out on the blk/yellow I do a rj 14 on the first jack and then on the on the last 2 pairs I do i do two rj11c that way it gives each location flexibility and the there are 2 independant data connection one blue and one yellow cat6a
I don't see a need for fiber to the desktop but we have run smurf tube for afterthoughts.....

 

[jerryreeve]

I try to talk the customers into at lest two cat 5 cables per drop wired as cat5 three cables if the customer is forward looking. then the customer can do simple AMC's themselves and can run two network devices at each drop or computer and phone etc. if they need to. the biggest thing is to give them flexibility.

The last thing I want is the "Customer" doing moves and changes ,next thing they will is doing there own wiring and were would that lead...

 

[DaveThePhoneDoctorLV]

Here is my jack color code: WHITE=station set, BLUE=data, ORANGE=fax, BLACK=miscellaneous voice device ( credit card reader, modem etc. )

 

[jeffmoss26]

I match the faceplate for voice and use orange or blue for data.

cwc3 that would lead right back to you. trust me on this one. they will remember you trying to help them and make things simpler.
