[Asterisk-Users] COnfiguring an * system for a non-profit organization

[Scott Stingel]

Hi Mike-

Not sure why your card seems dead, but your second crossover spec seems to
be the correct one.

Here's a link to a good diagram of the crossover cable (see the bottom of
the linked page).  Only 1, 2, 4, and 5 are used.  It is not necessary to
connect the others.
