installation and use of D-Link Fast Ethernet transceiver models
DFE-853 and DFE-854.
Introduction
D-Link Fast Ethernet transceiver models DFE-853 and DFE-854
represent the best value on the market. These transceivers are IEEE
802.3u compliant and support both half- and full-duplex operation.
Diagnostic LEDs are on the front, with the cabling connectors, for
maximum visibility.
Transceivers provide additional media options for Fast Ethernet
hubs, switches, bridges and routers equipped with MII ports. A
DFE-853/DFE-854 transceiver is recommended for a network
device with a built-in MII connector.
The DFE-853 MII to 10BASE-T or 100BASE-TX transceiver has
the Auto-negotiation function, which means the transceiver
automatically adjusts itself to the Ethernet speed (10 or 100) and
duplex mode (half or full) of the attached segment. When two auto-
negotiation devices with multiple capabilities are linked together,
they find their optimum common mode of operation.
