Telephone and Ethernet wiring

I have to wire a small office for phones and ethernet. I've assisted in this before, but I only did some of the ethernet wiring and Im forgetting all the details very quickly. I have never done any telephone wiring before. I was wondering if there were any useful sites on this and instructions on how to make a RJ-11 telephone cord. I cant seem to find anything solid in my searches.

The system will be simple, 4 phone lines and 1 fax in a hunt group. There will be 2 phones in the office that need to access all 4 lines and there will be one jack dedicated to the fax. So Im guessing Ill have to do some daisey chaining at the punch block. Has anyone daisey chained somethign like this before?

Will the phone company punch down the 4 lines and 1 fax at some punch block outside the office (there is no telephone wiring area inside the office) or leave 5 RJ-11 plugs? A voice line only uses 2 wires of the actual 4 correct?

Thanks
 
A voice only line does use 2 of the 4 wires. I believe the phone company will install everything in a box on the outside and it's up to you how you run the wires inside to connect to the box. Pretty sure the red and green are the standard colors of the phone wire that are used but don't quote me on that. I've never done a multiple line job but don't you have to have some kind of master box/phone that all 4 lines connect to?
 
Pull a couple "home runs" from each location / possible location back to a central place (the "Closet").

At least one of the runs will handle the phones (four phone lines per individual CatX cable) and the remaining will handle the network.

Line 1/ pair 1 is the middle-most pair (usually Blue/Blue-white) pin positions 4&5
Line 2 / pair 2 is the straddling pair (usually Orange/Orange-white for voice, IIRC) pin positions 3&6
Line3 / pair 3 is the left-most pair (usually Green/Green-White) pin positions 1&2
Line4 / pair 4 is the right-most pair (usually Brown/Brown-White) pin positions 7&8

The above corresponds to EIA/TIA 568A/ The connector is positioned with the clip down / away from you, with the opening towards you.

The solid color is the "Ring" side (of "Tip & Ring")

You can cable the data cabling the same way and be fully compliant.

You can punch both (Voice & Data) to the same panel on separate rows, but usually it's a better idea to have separate panels for voice & data.

-*-*-* DO NOT DAISY-CHAIN THE VOICE *-*-*-

If you need to bridge the lines together, do it on a 110 or 66 block in the closet, then feed the individual phone sets from the 110 or 66 block.

Good Luck

thanks for the replies.

4 voice + 1 fax, would that mean that the phone company will punch down a total of 5 pairs at the MPOE?

Scott, what would be the problem with daisy chaining at the punch block in the MPOE? sorry, im not experienced with this at all (luckily I have 3 weeks to learn).
 
From the Point of Entry, the circuits should go to a 66 or 110 punchdown. That should be your point of distribution into the panels that feed your field (the cubes, offices, whatever).

Just to make sure we're on the same page, Daisy-Chaining implies going to location A, then From A to B, from B to C, and so on.

Daisy chaining in an environment with structured cabling is a bad thing.

FWIW
