Shielding of individual signal or power pairs is not required because most V1.0 controllers and transceivers are DC-coupled. The overall AUI cable shield provides for shielding and grounding and is connected to pin 1 and the AUI connector shell.

In practice, most Ethernet V1.0 equipment uses version 2.0 cables due to cross-talk problems caused by the lack of individual shielding of the pairs in Version 1.0 cables.

Wire Sizes

The three versions of AUI cables also use differ- ent wire sizes for the signal and power pairs. Table 7 describes the wiring that each type of transceiver cable uses.
