Connect the Outside Lines to the Jack Field
1
Plug the connector on the 25-pair cable into the 50-pin connector at the
network interface.
2
With a jacket-stripping tool, slit the jacket at the free end of the 25-pair
cable, and cut away as much of the jacket as necessary to allow the
individual twisted pairs of color-coded wires to reach the jacks in the
jack field.
3
Following the order and color code in the drawing, right, use a cable
termination tool to punch the wires down into the grooves on the block
on the adapter. If you have more than four outside lines, continue to
punch wires down on the second adapter until you have connected a
jack for each outside line.
4
If your cable termination tool does not trim the wires as it punches them
down, trim the ends of the wires protruding from the grooves with a pair
of scissors.
