Stripping the Outer Insulation from the Twisted Pair

When connecting two Model 1000s, it is necessary to use a

"crossover" cable.  The diagram below shows how a crossover cable

should be constructed for an environment where both Model 1000s use
a 4-wire RJ-11 connector.  Similar logic should be followed when using
RJ-45 connectors or a combination of the two.
