I have a long telephone cable with a British telephone-wall-socket plug at
one end, the other end is naked wires. I'd like to fit a RJ-11 plug at the
exposed end so I can plug the cable into my modem and access the internet on
my Mac from a long way away from the wall phone socket. I've bought a RJ-11
crimping tool, one RJ-11 plug, and searched the web for info, but still
can't work out which way the plug should be attached. The exposed end of the
phone wire has 4 strands within it, coloured (sequentially) white-blue,
white-red, red, blue. As I understand from the web, the inner two wires
(white-red and red) are the primary phone line, the outer two (white-blue
and blue) are the secondary phone line....? (Not sure what this means, or
whether its relevant.) I experimented by attaching the plug with the wires
in that order as you look down at the face of the plug that has the exposed
copper contacts (i.e. with the spur/catch thinggy on the underside), but the
modem couln't succeed in dialling up...
Any wire experts out there? Should I just buy another plug and try attaching
it the other way round? There is one confounding detail in my experiment as
I also stripped the insulation several inches off the cable nearest the
plug, and I understand from the web that this this exposure of the core
wires might lead to serious interference in the cable. Also probably
relevant is the overall length of the cable... I haven't unravelled it yet,
but I reckon it might be 30 feet (10 m) long or more.... Could the length
alone stymie any attempts at getting it to work?
If the modem idea doesn't work or isn't feasible (e.g. because cable is too
long), I was wondering if I could turn the cable into Localtalk (PhoneNet)
cable? I presume yes, as I remember reading Apple documentation that said a
Localtalk cable could be up to 100 metres long... I have PhoneNet
connectors, and have also identified a reason why I might need such a long
cable (possible weather logging station in an outhouse... don't ask me yet
how I will actually do the weather-logging, although I have a spare
Plus!!).... but again, I can't find explicit instructions on how to wire up
the RJ-11 plugs on British phone cable.
Seems like American phone cable has an inner pair of green and red wires
('Christmas') and an outer pair that is yellow and black ('Halloween')....
but clearly British cable has different colours. I inherited this old cable
off my office, so I assume it was bought in UK and is British standard phone
cable....
Any enlighten ment as to how to wire up the RJ-11 plug(s) to make either a
modem cable or a Localtalk (PhoneNet) cable would be very much appreciated.
Mike
