common modes of operation without any user inter-
vention or prior knowledge by connected stations
See the 82595FX User’s Guide for details on this
function
For further information on these enhancements
and a description of all the differences between
the 82595TX and 82595FX please consult the
82595FX User’s Manual available through your

1 4 Compliance to Industry Standards
The 82595FX has two interfaces the host system
interface which is an ISA bus interface and the seri-
al or network interface This interface has been
standardized by the IEEE
1 4 1 BUS INTERFACE
ISA IEEE P996
The 82595FX implements the full ISA bus interface
It is compatible with the IEEE spec P996
1 4 2 ETHERNET TWISTED PAIR ETHERNET
INTERFACE IEEE 802 3 SPECIFICATION
The 82595FX’s serial interface provides either an
AUI port interface or a Twisted Pair Ethernet (TPE)
interface The AUI port can be connected to an
Ethernet Transceiver cable drop providing a fully
compliant IEEE 802 3 AUI interface The TPE port
provides a fully compliant IEEE 10BASE-T interface
The 82595FX can automatically switch to whichever
port (TPE or AUI) is active
