Crossover Cable
A crossover cable connects a MDI device to another MDI device, or a MDI-X device to another MDI-X device. Figure 5
depicts a typical crossover cable connection between two switches or hubs (two MDI-X devices).

LinkMD
Cable Diagnostics
The LinkMD
function utilizes time domain reflectometry (TDR) to analyze the cabling plant for common cabling problems,
such as open circuits, short circuits and impedance mismatches.
LinkMD
works by sending a pulse of known amplitude and duration down the MDI or MDI-X pair, and then analyzing the
shape of the reflected signal to determine the type of fault. The time duration for the reflected signal to return provides the
approximate distance to the cabling fault. The LinkMD
function processes this TDR information and presents it as a
numerical value that can be translated to a cable distance.
LinkMD
is initiated by accessing register 1Dh, the LinkMD Control/Status Register, in conjunction with register 1Fh, the
PHY Control 2 Register. The latter register is used to disable auto MDI/MDI-X and to select either MDI or MDI-X as the
cable differential pair for testing.
