Ethernet Cables

• 47

Note: It's important that each pair is kept as a pair. TX+ & TX-
must be in one pair, and RX+ & RX- must together in another
pair. (Just as the table above shows).

This is how the pairs are named:

The + side of each pair is called the "tip" and the - side is called the "ring",
a reference to old telephone connectors.

Cross-Over Cable

This cable can be used to cascade hubs, or for connecting two Ethernet stations back-to-back without a hub.
It works with both 10Base-T and 100Base-TX.
