4.5. Ethernet 10/100 Mbps (Fast Ethernet) PCI Controller (DCCG137 , DCCG143 and
DCCG161)
DCCG143 Discontinued: 15/09/2003.
The Ethernet 10/100 Mbps PCI Controller is a Fast Ethernet network adapter that allows an Escala
system to connect to 10 Mbps or 100 Mbps Ethernet network. It works with PCI (Peripheral
Component Interconnect) buses and connects to any 10Base-T or 100Base-TX compliant Ethernet hub
to deliver 10 times the bandwidth delivered by Ethernet. The adapter automatically selects between 10
and 100 Mbps operation.
For 100 Mbps operation, the adapter supports operation on category 5 UTP cables.
For 10 Mbps operation, the adapter supports Category 3, 4, or 5 UTP cables.
Connectivity Rules
The maximum length of a twisted pair segment- distance from a repeater to a host system-is 100
meters.
The diameter of collision domain -distance between two end-stations- is 205 meters.
