The fi rst step in the Level 2 process is to read the link pulses of the
LAN device and determine its advertised capability. Every LAN device
broadcasts its capability in terms of speed, duplex and other features
(termed "advertised" capabilities) to other LAN devices.

First example (above): The RWC1000 has found a gigabit device
(1000MB) on pairs 1,2 and 3,6 that is capable of transmitting at 10MB,
100MB and 1000MB at full duplex. 1000 MB devices use all 4 pairs.

Second example (above): The RWC1000 has found a 100MB device
on pairs 3,6 that is capable of transmitting at 10MB and 100MB at
half duplex. Typically, devices that transmit on pairs 1,2 are PCs and
devices that transmit on 3,6 are hubs and switches.

When completed, press the down arrow key ( ) to continue.
