Class II Fast Ethernet repeater, allowing it to be linked to another Class II Fast Ethernet stack in the same collision domain.

On the DFE-908, the 10Mbps and 100Mbps segments are separate and do not intercommunicate. The DFE-908x contains a built-in switch, making it possible to transparently bridge between the 10 Mbps and 100 Mbps seg- ments.

Product Features

The list below highlights the features and specifications of the DFE-908 series hubs:

Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u 100BASE-TX Fast Ethernet industry standards for interoperability with other Ethernet/Fast Ethernet network devices.

Ethernet connections support Category 3 or better twisted-pair ca- bles.

Fast Ethernet connections support both shielded twisted pair and Category 5 unshielded twisted-pair cables.

Fast Ethernet connections support a maximum distance of 100 me- ters from end-station to hub, and a total network diameter of 205 meters.

Eight NWay RJ-45 ports for connecting stations to the network.

Built-in switching function (DFE-908x only) supports bridging be- tween 10Mbps and 100Mbps segments. Only one DFE-908x is needed per stack.
