When connecting like devices one uses a crossover. Example: PC to PC, router to router, switch to switch. For all other types of connections one uses a regular network cable. Example: switch to PC, router to switch etc.

The purpose of the wires is pretty simple, transfter of data.

Hi,

Many devices will also implement the Cross-Over as
required internally while some don't. If both are
of the later type, you need a Cross-Over cable but
the chances are they won't so i believe Cross-Over
cabling will do the job more often, in comparison.

Actually a patch [straight thru] is a better all round choice. If the equipment has mdix [autosense cable type]it will adjust automatically if being used in a crossover situation.

Hi,

What about similar devices if none has auto-sense?

Right... Both cables are OK when at least one end
can insert a cross-over internally, it's when both
are alike and none supports this feature that i'll
really appreciate having Cross-Over cables around,
right? So, why do you prefer a straight-through!?

not sure what your question is.

after being in this business for 15 years working for mid to large size companies, patch cables are used 100 to 1 [or higher]more often than a crossover. With mdix aware appliances becoming more common I don't even need to use a crossover.

So if you have older equipment you wish to innerconnect should you have crossovers available? of course.

Which are you going to use more often? Patch

so what was your question/point?

Hi,

This question should sound clearer: can you think
of an instance where a Cross-Over cable will fail?

With fifteen years of practice behind you to neck-
tie, it should be easy to provide an illustration!

Ah a discussion with no purpose. I was being helpful and it appears you just want to play. Best of luck!

Hi,

Wa> Ah a discussion with no purpose.

The question seems valid to me, perhaps it was the
insistance over your preference for straight-thrus
and which remains unexplained that had no purpose.

I don't see how that would be helpful if one comes
back from his local store with a 50' straight-thru
cable hoping to transfer files between two Windows
systems and both have LEGACY NICs. What does this
accomplish if in fact a Cross-Over cable will work
in a majority of situations encountered by a user?

Making others waste money isn't my idea of a game.

The discussion was about wiring crossover vs straight and when to apply each. CurtR did an excellent job answering the question.

You chime in saying "i believe Cross-Over
cabling will do the job more often" which brings my rebuttal to the contrary. I list my reasons.

You then isolate the discussion to just HOME use. OK so lets look at that

PC to PC = xover
PC to hub = patch
PC to switch = patch
PC to isp's internet modem = patch

That's 3 to 1 in favor of patch

Now lets throw in mdix
PC to PC = no mdix so still xover
PC to hub = no mdix so still patch
PC to switch with mdix = patch still works so why use a xover?
PC to modem = no mdix so still patch.

Still comes down to 3 to 1 in favor of patch.

Your arguement has no basis.

This is why I think this discussion is pointless. You don't have a valid point when you consider the original discussion or the scenerios I present.

We get folks here all the time that didn't do their homework and wonder why things don't work. Homework didn't end with school. Life and computing is school. That's how some folk learn the difference between xover and straight - the hard way.

PS. its not a waste of money on the 50'. The ends just have to be redone that's all.

I'm new at this. I put this together after poking around the net. Is it correct?

router switch hub pc
router xover xover straight straight
switch xover xover xover straight
hub xover xover xover straight
pc xover straight straight xover

To answer your question I can't read "it" [your posted list] but below is a good guideline.

PC to PC = xover
PC to hub = patch
PC to switch = patch
Hub/switch to hub/switch
with no uplink = xover
Hub/switch to hub/switch
with uplink = patch
PC to router = patch
Modem to router = patch
PC to isp's internet modem = patch
Router switch port to router switch port = xover
