I have seen the future.

Why are you terminating crossover cables, anyway? Pretty much all modern switches (and GIGE by IEEE spec) will autoneg this.

From:

I'm not terminating crossover cables. I'm making perfectly normal non-crossover cables.

From:

Not with that pattern. That's the oddball end of a crossover cable.

Seems like a normal cable to me.

From:

I was taught how terminate cables by an ancient Bell guy (like, from the pre 1983 breakup era), and the pattern I posted first in thread was the normal telco standard (which is why I suspect John called me the devil). As long as both ends match, it doesn't really matter (except of course, the proper pairs should be kept together). Hell, you CAN use 8 wire ribbon cable terminated straight across for ethernet if you really want, but don't expect great performance out of it.

From:

I just figured crossover cables were evil.

From:

True evil is terminating 24 pair bundles. I used to know how to do that too. The last pair was left for use as either a spare, or as half of a T1 (which was always separated by 24 pair, unless your local provider was incompetent, T1s were carried over STP or the unused pairs from two 25 pair bundles).

My spouse (reyl) is correct. i know she is correct - i taught her.

TIA 56A is WG,GR,WO,BL,WB,OR,WBr,BR.

in a crossover (TIA 56B), it's the same as above on one end, and WO,OR,WG,BL,WB,GR,WBr,BR on the other end.

These are the standard in the telecom industry.

for the record, most Bell techs, ancient or otherwise do not know how to cable properly. i could tell you horror stories. also, you cannot use 4 pair ribbon unless you want to completely bag out your network with crosstalk from hell.

From:

These are the standard in the telecom industry.

Actually, like I said, TIA 56B is AT&T's standard way of doing things, defined Long Long Ago, but the US DOD went with the other method.

also, you cannot use 4 pair ribbon unless you want to completely bag out your network with crosstalk from hell.

That's pretty much what he said, actually.

From:

The old Bell guy I learned from wasn't your average truck monkey fucking up circuits in closets, he was an engineer. As John pointed out, the telecom standard predates the others, and depending on who you ask, is the "correct" one.

Now, I'm a DoD contractor these days, and just to annoy them, I make a point of terminating to telco standards. Most mass market pre-terminated Cat[5|5e|6] uses the telco layout.

As John also noted, I pointed out that yes, using straight through ribbon cable is going to suck.

From:

Uh, no, that's BOTH ends of a standard cable, unless you're AT&T.

I'm not AT&T.

From:

It's a telco standard. Shit, why do you think the middle two pair match up with standard RJ-11? Hmmm?

From:

Because Satan wants it that way.

From:

While I'm no fan of what became of the Bell System after the break up, AT&T wasn't the monster people accuse them of having been.

Two more mergers, and we have Ma Bell back, except that there's no longer a single circuit, billing, trouble, etc system in place.

Frankenstein would be proud of our monster.

From:

This has nothing to do with AT&T, and everything to do with the fact that the One True Way of wiring this cables is the way I have been doing it, and the reason this is the One True Way is that if I change that I'd have to go back and redo some of them.

As of now, the One True Way is irrelevant, because I'm done doing dumb network cable shit for today, but up until this very moment doing it your way would have resulted in either a crossover cable or me having to cut off perfectly good cable ends and redo them, because I *started* with a perfectly good 10m cable and now I have 5 perfectly good 2m cables.

From:

You know, cables are cheap. I don't terminate them by hand anymore unless I have a very specific reason.

Like, the 1000' spool of Red Cat5e next to my desk and the box of RJ-45s on it. I'm not looking forward to that bit of wiring.

From:

I've got a couple of those gargantuan spools, too. Just not at my desk, right now.

From:

It reminds me of:

Blue Blue. Blue Red. Blue Orange. Blue Green.
Red Blue. Red Red. Red Orange. Red Green.
Orange Blue. Orange Red. Orange Orange. Orange Green.
Green Blue. Green Red. Green Orange. Green Green.

But I think perhaps that nobody remembers that anymore.

My Mom quotes that one. She did that for a job growing up.

From:

You can get paid for playing DND?

From:

ucnu112.livejournal.com

She described a very similar pattern to wiring telephone systems. It's been a while since I've heard her say it... and she hasn't been 'growing up' for a while either. =)

From:

That's a D&D thing?

From:

DND. What I posted was the easiest way to open the treasure vaults.

From:

Oh, hey, I remember that now.

From:

On the DOS version, The Warren had a TRV that was, if you knew where the secret doors were, very easily accessible from the stairs up. So you could very easily gain millions of gold and tons of levels simply by running to the TRV, hitting a jackpot, and then running back to the stairs (since leaving the dungeon granted XP equal to half your carried gold, you would often level).

It was great being nine.

God help you, that is getting stuck in my head.

From:

You can always just play it, I suppose.

Not from that link, you can't.
