I agree, and I
suspect any straight-through RJ-45 cable
was for a telephone system, not networking. Perhaps
Sellam knows examples.
I've encountered flat 8 core cable, terminated with RJ45's, used as patch
leads in a Serial environment. They were used with Baydek SMUX serial
boards, also seen them used with some Specialix terminal servers, both had
RJ45 sockets for the serial ports.
And also the included console cable on much Cisco gear for years. Got boxes
of 'em. I've always gotten RJ45's on both ends, until recently a PIX
firewall showed up with RJ45 on one end, molded connector on the other. I
tossed it and used an old-style cable (one size fits all). --Patrick
