The Importance of Proper TIP and Ring Wiring
Due to the high speed digital signaling over the wire pair, it is important to verify that
the wiring is free of potential problems. The wire pair feeding the terminals must be
low capacitance, continuously twisted wire.
The wire gage and type should be consistent for the entire loop length. More than one
type or gage of wire spliced together in the same loop will reduce the maximum
possible loop length of the station or trunk.
Always match the twisted pair of a loop to corresponding tip and ring connections. Do
not connect the wires of the same twisted pair to different tip and ring connections. See
