Mark the box with the letter of the closet to which the DIW cable is
pulled and with the circuit number of the wire. This is the same as the
number you wrote on the wire sheath. Wire 1 becomes circuit 1; wire 2
becomes circuit 2.
At the boxes next to the offices, pull out enough wire to reach the wall
jacks. Allow plenty of slack.
Cut the wire and mark the end of the DIW cable with the closet letter
and the circuit number.
After you pull the wire into the office or work area and fish it through the
wall opening for the wall jack, transfer the information to the faceplate
of the jack itself.
You should now have the correct closet letter and circuit number of the
wire on the jack.
When the DIW cable reaches the control unit cross-connect field,
punch down the pairs in the same sequence as labeled on the sheath.
On the blue lables designed for the 110-type field-terminated block,
add any necessary information. With pre-printed labels, you add only
the floor number. With blank labels, you also have to write in the closet
letter and the number from the wire sheath.
If no labeling exists, simply assign a different number to each DIW cable and
write that number on both the box and the wire end.
