Link Beat

Type 10Base-T devices use a signal called link beat (also called link test pulse).

This signal informs the hub of the presence of a device connected to it over

twisted-pair cable and of the integrity of the twisted-pair link between them.

The hub will not transmit packets out of twisted-pair ports that do not sense

the link beat signal. Link beat is reflected in the port LEDs; the LED will be on:
