Introduction
Thank you for choosing the D-Link DFE-520TX, the value leader among Fast Ethernet adapters
for PCI Bus personal computers. This introduction gives a general description of the newer
networking technologies found on the DFE-520TX.
The DFE-520TX provides IEEE 802.3x Flow Control Enhancements, which are needed for a
network adapter to function with a switch. In full-duplex mode, the MAC implements the PAUSE
control function. This means when a switch is connected in full-duplex mode and it senses that
its buffer will overflow in the near future, the switch will transmit one standard Ethernet packet
that causes the DFE-520TX to pause for a period, thus avoiding internal buffer overflow and
packet loss.
