Removing Patch Cords/Jumper Wires
When it is necessary to remove a patch cord/jumper wire because a
telephone/voice terminal is being removed, disconnect the
telephone/voice terminal at the information outlet. Then, remove the
patch cord/jumper wire from the cross-connect field. This gives a visual
indication of the available terminal/connecting block terminals
associated with port and station jacks. Do not leave a partially or totally
disconnected patch cord/jumper wire intermingled with the remaining
patch cords/jumper wires.
When it is necessary to rearrange patch cords/jumper wires because of
telephone/voice terminal moves, remove the patch cord/jumper wire
and reinstall it even if only one end of the cross-connection is affected.
This reduces entanglement and helps to assure a neat appearance.
To remove a patch cord/jumper wire, proceed as follows:
1.
2.
3.
4.
5.
6.
On the Port Assignment Record(Figure 4-11), locate the
terminal/connecting block associated with the jack assignments at
the purple and white or blue fields.
At the purple field, disconnect the patch cord/jumper wire (see
Note).
Note: An impact tool or 724A tool (for 66-type hardware
only) is required when removing jumper wires.
Lift the patch cord/jumper wire upward, taking up slack, until the
patch cord/jumper wire can be located by its movement in the patch
cord trough/187B1 backboard.
Trace the other end to its connection point at the blue or white field
and disconnect the patch cord/jumper wire.
Remove the patch cord/jumper wire from the patch cord
trough/187B1 backboard.
Update the Port Assignment Record (Figure 4-11).
