Using CAT5 for Phone Lines, and other Media.

By: ScottMac. (www.scottmac.cyberspace)

CAT5 was design equally a Multi purpose Cable, to be used in transfer diverseness of Information Indicate.

Information technology typical use is for Computers Network; however it is used for Phone and other Media.

Note: It is important not to employ multifariousness of media in the same Cable since the Electric fields might interfere one with the other.

Following the standard of Pinout connection is very important, it helps in avoiding mistakes, and provides a amend chapters to maintain the runs if something goes incorrect in the futurity.

The Pinout of TIA/EIA 568a and 568b wired a jack is completely "phone uniform."

For Phone lines:

Pair 1 is the blue pair on pins 4 & 5, which corresponds to telephone line ane
Pair 2 is the (green or orange) pair on pins three & six, which corresponds to telephone line ii
pair three is the (orange or dark-green) pair on pins 1 & 2, which corresponds to phone line 3
pair 4 is the dark-brown pair on pins vii & 8, which corresponds to telephone line 4

Ethernet uses pair 2 & 3 (orange and greenish)

Token Ring uses pair 1 & ii (blue and (orangish or green))

T1 uses pair 1 & 3 ((orange or green) and blue)

56K / DDS uses pairs 3 & four ((orangish or dark-green) and chocolate-brown)

ATM uses pairs 3&four (for 155 or 25 meg - older 25Meg ATM used pair ii & iii, same as Ethernet)

The (orangish or greenish) reference is because TIA/EIA 568B uses greenish @ pair 2, TIA/EIA 568A uses the orange pair @ pair 2).

And then, the Pinout for 568A, (With the plug clip downwardly/away from you) would exist:
Green-White, Green, Orange-White, BLUE, BLUE_WHITE, Orange, Brownish-white, Brown.

This would be the preferred Pinout under strict telephony conventions. The Blue pair (pair one) is swapped (Blue, Blueish-WHITE) compared to the other pair.

The Pinot for TIA/EIA 568B is the same except the orange & green pair are swapped (568A = orange pair 2, 568B = Green pair ii).

When using CAT5e, pair guild is less disquisitional for performance, since all pairs are qualified for high-speed data, but ordering your pair according to the Environmental impact assessment/TIA standards arrive easier to recall "how you did it" six months later, and offers no frustration to the side by side person trying to use your cabling system. Yous accept to exercise it from scratch, so you may as well do it "correct" the first time. It takes no boosted effort to do it correct.

On a punch system, most often the white wire goes on the left side of the post ... just like in the connector. Near punch blocks now have an explicit color code label to indicate which colour goes where .... follow that label.

Other rules yous should be aware of if yous're pulling the cablevision:

Keep the pulling tension under 15 pounds (information technology's different from i manufacturer'southward cable to another, only 15 is a condom value for all)

All bends (everywhere, no exceptions) should have a radius of NO LESS THAN 4 times the diameter of the cable ( ii" is ordinarily quoted)

The maximum exposed (unjacketed) pair is ane/2" (one half inch, MAX)

The maximum length of untwisted pair for termination is ane/2" (less is much better - keep the twist upwardly to the termination).

Brand sure that, the exposed pair length and the untwisted pair length is the Same half inch.

DO Non (as in NEVER EVER) compress, crush, knot, twist, or kink the cable or jacket (don't cinch the cable ties tight).

The spec is for 90 Meters of SOLID cabling "in the wall" and 5 meters of stranded patch at each end (100 meters full). This is not an accented, just a skilful solid "rule of pollex".

No matter how much cheaper you can buy it, NEVER NEVER NEVER run Stranded cabling in the walls. Stranded has a much higher loss than solid conductor UTP cabling.

Buy solid for the walls, stranded for patch cables.

Maximum run of CAT5 is "100 meters", however this dominion does not utilise to stranded cabling: stranded cabling cannot pass a signal for 100 meters ... it loses as well much.

Be aware that there are basically four types of crimp-on plugs:

Flat (stranded or solid) and round (solid or stranded).

Make sure you lot have the right kind of plug for the cable you are crimping (usually "round" and "stranded" for a patch cable) it should be explicitly labeled as a "CAT5" (or Cat5e or Cat6). Cheap, unlabeled plugs may bring your cool new Cat5 / Cat5e / Cat6 cabling job down to "telephone grade" unrated cabling. The plugs for "flat" are for phone apply only -NEVER- apply a "flat" plug for category-rated cabling.

(There are a bunch of others; these are the top of the listing. Follow these rules and y'all're usually right in there for certified sweeps)
