Product Features

Auto-Negotiation

The Auto-Negotiation feature allows the J/E-PSW-FX-02 media converter to
automatically configure itself to achieve the best possible mode of operation
over a link. The media converter broadcasts its speed (10 Mb/s or 100 Mb/s)
and duplex capabilities (full or half) to the other devices and negotiates the
best mode of operation. Auto-Negotiation allows quick and easy installation
because the optimal link is established automatically. No user intervention is
required to determine the best mode of operation.

A scenario where the media converter is linked to a non-negotiating device,
disable Auto-Negotiation. In this instance, the mode of operation will drop to
the least common denominator between the two devices (e.g., 10 Mb/s, half-
duplex). Disabling this feature gives the user the ability to force the
connection to the best mode of operation.

AutoCross™

When the AutoCross feature is activated, it allows either straight-through
(MDI) or crossover (MDI-X) copper cables to be used when connecting to
10Base-T or 100Base-TX devices. AutoCross determines the characteristics of
the connection and automatically configures the unit to link up, regardless if
the copper cable is MDI or MDI-X configuration.

Full-Duplex Network

In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See page 1 (front cover) for the cable specifications
for the different J/E-PSW-FX-02 models.

The 512-Bit Rule does not apply in a full-duplex network.

Half-Duplex Network (512-Bit Rule)

In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A collision

domain is the longest path between any two terminal devices, e.g., a terminal,
switch, or router.)

The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.

For more information on the 512-Bit Rule, see the white paper titled
“Collision Domains” on the Transition Networks website at:
www.transition.com.
