DIY - Structured Wiring

Copyright Randy Melton 2007



Section 1 - Basics

Structured Cabling is defined as building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements. That term is probably overused to describe typical home networking and phone wiring. My goal was to have a reasonable system to allow wired ethernet and phone connections in multiple rooms of our house. I wanted a wiring box in the basement that would be easily accessible, relatively cheap and still look nice. I considered a sheet of plywood with bobbin connections. I decided to go 1 set up with a simple metal box, punchdown-plug hubs, and power for a phone surge/adsl/security filter.

Section 1 - Existing Wiring

My house already had a single cat5e line run from each room into the basement. This was done by the builder/electrician to wire a single phone jack in each room. In the basement these 9 cables (one from outside, 8 wired rooms) were left hanging with the 8 sets of 9 conductors spliced together using wire nuts. My DSL Modem already has a built-in 4-port router. I plan to place this in wiring box and distribute it to 4 rooms from there.

Section 3 - Wiring Conventions

WARNING: I'm simplifying the specs and wiring below. Phone and ethernet wiring is very simple and easily doable by most people. If you are unsure or don't understand these notes you should not attempt to do you own wiring.

Hold the plug up (cable down) with the pins facing you. The pins are numbered from left to right. (need a picture showing how to identify pin1)

Note that on the wall plate phone jack I shorted line-1 with line3, and line-2 with line-4. This is because the WPA-PDC has 2 phone jacks "line-1/2" and "line-3/4". By creating these shorts I am able to have two usable phone jacks in each rooom.
