Re[2]: Phone frying network

["Pete Shew" <ukha_d@xxxxxxxxxxxxxxxxxx>]

I wired the green and orange pairs to pins 1, 2, 3, and 6 and used the blue
pair for phone.  Using a phone exchange all phones are masters, so two wire
is OK, but the brown pair could be used too for the antitinkle. I made up
RJ45 to flying master sockets for the phones with that wiring.

For the Y cable, I routed the green and orange pairs to a RJ45 socket and
the others to the phone socket.

Totally DC isolation and no problems of accidentally incorrectly patching.
