<P><FONT SIZE=2>The wiring pattern that you are using is correct for EIA/TIA 568B which is what you want to use. It is the industry standard for a straight through cable. For a crossover cable you would build one end with the 568B pattern and the other end with the 568A pattern which is as simple as crossing the orange with the green (White-Orange becomes White-Green and vice versa; Orange becomes Green and vice-versa). More generically you swap the 1 and the 3 then the 2 and the 6. Here's you a chart:</FONT></P>
<P><FONT SIZE=2>White Orange=1</FONT>
<BR><FONT SIZE=2> Orange=2</FONT>
<BR><FONT SIZE=2> White Green=3</FONT>
<BR><FONT SIZE=2> Blue=4</FONT>
<BR><FONT SIZE=2> White Blue=5</FONT>
<BR><FONT SIZE=2> Green=6</FONT>
<BR><FONT SIZE=2> White Brown=7</FONT>
<BR><FONT SIZE=2> Brown=8</FONT>
</P>
<P><FONT SIZE=2> EIA/TIA 568B (StraightThrough)= 12345678 on both ends</FONT>
<BR><FONT SIZE=2> EIA/TIA 568A (Crossover)= 12345678 on one end and 36145278 on the other</FONT>
<BR><FONT SIZE=2> (Rollover)= 12345678 on one end and 87654321 on the other</FONT>
</P>
<P><FONT SIZE=2>It is quite possible that I am wrong on the standards (as far as EIA/TIAx) goes but I do not think so. As far as the color code chart I know that I am right and that is all that you need to know to make some cables. The codes in the chart are for a male RJ45. For female you would just follow the B pattern that should be on the jack.</FONT></P>

<BR><FONT SIZE=2>Subject: [NTLUG:Discuss] LAN Planning</FONT>
</P>
<BR>
<P><FONT SIZE=2>I need some suggestions for designing a LAN I want to put into my </FONT>
<BR><FONT SIZE=2>(new, as in still-smell-paint new) house.</FONT>
</P>
<P><FONT SIZE=2>Objective: Most of the computer equipment will be centered in a </FONT>
<BR><FONT SIZE=2>bedroom, but one computer won't be in that bedroom, and it is </FONT>
<BR><FONT SIZE=2>necessary to connect that computer to the LAN.</FONT>
</P>
<P><FONT SIZE=2>CURRENT SETUP:</FONT>
</P>
<P><FONT SIZE=2>I have two physically independent networks, one running 10.x.x.x, </FONT>
<BR><FONT SIZE=2>one </FONT>
<BR><FONT SIZE=2>running live IPs. The live IP one runs 10BaseT. The 10.x.x.x runs </FONT>
<BR><FONT SIZE=2>100BaseT. The private network is used for things like local IMAP, </FONT>
<BR><FONT SIZE=2>SMTP relay, and NFS. The public network is used to connect to </FONT>
<BR><FONT SIZE=2>the </FONT>
<BR><FONT SIZE=2>net without the hassle of a proxy.</FONT>
</P>
<P><FONT SIZE=2>All wiring lays on the floor and is a trip and choke hazard. I have </FONT>
<BR><FONT SIZE=2>a very small baby and I'm trying to clean things up some.</FONT>
</P>
<P><FONT SIZE=2>DESIRED SETUP:</FONT>
</P>
<P><FONT SIZE=2>Looking for suggestions.</FONT>
</P>
<P><FONT SIZE=2>Functionality requirements, notes and questions:</FONT>
</P>
<P><FONT SIZE=2>1) A single physical network is nice but not strictly required. The </FONT>
<BR><FONT SIZE=2>private side network must run 100meg. The hub on that network is </FONT>
<BR><FONT SIZE=2>a </FONT>
<BR><FONT SIZE=2>3Com 100BaseTX hub with a couple of fiber inputs. It will -not- </FONT>
<BR><FONT SIZE=2>switch down to 10 megabits.</FONT>
</P>
<P><FONT SIZE=2>2) Easy to wire. Patch panel optimal. It can go in a closet.</FONT>
</P>
<P><FONT SIZE=2>3) Easy to expand to additional ports. Big patch panel? (How </FONT>
<BR><FONT SIZE=2>many </FONT>
<BR><FONT SIZE=2>ports would be good? This is a 4br 2150 sqft house. I want ports in </FONT>
<BR><FONT SIZE=2>at least three bedrooms, and possibly the formal living room which </FONT>
<BR><FONT SIZE=2>we're turning into a library.)</FONT>
</P>
<P><FONT SIZE=2>4) The Internet connectivity will be coming through some sort of </FONT>
<BR><FONT SIZE=2>10BaseT port, either an Ascend Pipeline 50 or 85, or some kind of </FONT>
<BR><FONT SIZE=2>xDSL modem/router thing. This means that a proxy is necessary </FONT>
<BR><FONT SIZE=2>unless </FONT>
<BR><FONT SIZE=2>we go with two physical LANs.</FONT>
</P>
<P><FONT SIZE=2>5) Money is an object, but plenum cable is absolutely required. </FONT>
<BR><FONT SIZE=2>Please tell me where it can be found at the price-performance </FONT>
<BR><FONT SIZE=2>sweet </FONT>
<BR><FONT SIZE=2>spot. :)</FONT>
</P>
<P><FONT SIZE=2>6) In that same line of thought, does somebody have a punchdown </FONT>
<BR><FONT SIZE=2>tool </FONT>
<BR><FONT SIZE=2>I can borrow, or know where can I get one for not-a-lot? Will also </FONT>
<BR><FONT SIZE=2>need wall plates, wall plate pop-ins, male RJ45 ends, and a </FONT>
<BR><FONT SIZE=2>crimper.</FONT>
</P>
<P><FONT SIZE=2>7) If we locate a wiring closet in one of the bedroom closets, what </FONT>
<BR><FONT SIZE=2>can be done to make the hole in the ceiling pretty? Just leaving an </FONT>
<BR><FONT SIZE=2>empty hole isn't a good idea. Would piss off the wife major bad.</FONT>
</P>
<P><FONT SIZE=2>8) Is there a standard color pattern for wiring in a house? When </FONT>
<BR><FONT SIZE=2>I've built cables, I've done it like this (hook facing away):</FONT>
</P>
<P><FONT SIZE=2>LEFT</FONT>
<BR><FONT SIZE=2>Orange-White</FONT>
<BR><FONT SIZE=2>Orange</FONT>
<BR><FONT SIZE=2>Green-White</FONT>
<BR><FONT SIZE=2>Blue</FONT>
<BR><FONT SIZE=2>Blue-White</FONT>
<BR><FONT SIZE=2>Green</FONT>
<BR><FONT SIZE=2>Brown-White</FONT>
<BR><FONT SIZE=2>Brown</FONT>
<BR><FONT SIZE=2>RIGHT</FONT>
</P>
<P><FONT SIZE=2>9) There is a lack of telephone jacks in this house (only one in the </FONT>
<BR><FONT SIZE=2>kitchen and another in the master bedroom). I know it's certainly </FONT>
<BR><FONT SIZE=2>possible to run landlines on the unused CAT5 pairs; is it wise? </FONT>
<BR><FONT SIZE=2>Should I simply drop new line?</FONT>
</P>
<P><FONT SIZE=2>10) For each faceplate I was planning two RJ45 ports, each with it's </FONT>
<BR><FONT SIZE=2>own 4 pair lead. Should I simply consolidate them and go for using </FONT>
<BR><FONT SIZE=2>all four pairs, forgetting for the moment the landline issue?</FONT>
</P>
<P><FONT SIZE=2>11) Wiring closet in the bedroom closet, or in the garage? Garage </FONT>
<BR><FONT SIZE=2>is </FONT>
<BR><FONT SIZE=2>not AC'd (obviously), which is my only major concern about putting </FONT>
<BR><FONT SIZE=2>it </FONT>
<BR><FONT SIZE=2>there.</FONT>
</P>
<P><FONT SIZE=2>IN THE ALTERNATIVE, should I simply forget wiring the walls and </FONT>
<BR><FONT SIZE=2>go </FONT>
<BR><FONT SIZE=2>for the 802.11x solution for the one computer not in the bedroom? </FONT>
<BR><FONT SIZE=2>If </FONT>
<BR><FONT SIZE=2>I do, I'll have a number of walls to go through, all sheetrock.</FONT>
</P>
<P><FONT SIZE=2>This is a brand new house. I don't want to do this half-assed by </FONT>
<BR><FONT SIZE=2>just running Cat5 through a hole punched in a common wall, but I </FONT>
<BR><FONT SIZE=2>don't want to spend a fortune on it either.</FONT>
</P>
<P><FONT SIZE=2>Floorplan, for your enjoyment, is at </FONT>
<BR><FONT SIZE=2><A HREF="http://www.goldblatt.net/floorplan.png" TARGET="_blank">http://www.goldblatt.net/floorplan.png</A> (450k). The office will be </FONT>
<BR><FONT SIZE=2>"BEDROOM 4," and the wiring closet will be in the closet for </FONT>
<BR><FONT SIZE=2>"BEDROOM </FONT>
<BR><FONT SIZE=2>4." The location of the non-office computer is unknown at this time, </FONT>
<BR><FONT SIZE=2>but let's assume less than 100 wire meters including patch cables.</FONT>
</P>
<P><FONT SIZE=2>The "library" referenced above is on the floorplan as "LIVING." The </FONT>
<BR><FONT SIZE=2>real living room for everyday use is labeled "FAMILY."</FONT>
</P>
<P><FONT SIZE=2>Your experience is appreciated. :)</FONT>
