Re: Re: Cat5 cabling

Rob,

I'm sure there is a standard, but I didnt use it consciously.  Looking at
the plugs so you can see the metal contacts on both plugs, I just wired the
4 colours from the phone plug parallel to the middle 4 of the RJ45.  What I
am calling baluns is the top picture here: http://tinyurl.com/btkd  This
company calls them tailed voice adaptors...  We use them at work for the
structured cabling, which I assume was wired in to a cat5 standard, so my
'adaptor' working with these implies that (apart from the solid cores) was
to standard.
