Yes, it's surprising the number of mis-made DIY cables you see. A colleague
of mine specialises in making the worst UTP cables you could imagine. :)
Stranger still, they sometimes work!

If anyone needs a good reference to UTP cabling standards (in particular,
pairing patterns), here's some good reference material:

Alternatively, just enter "EIA/TIA 568A 568B" into any good search engine.
