Product Features
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 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.
NOTE: Factory default is “enable AutoCross.” Transition networks
recommends leaving the device in the “enable” mode.
Link Pass Through
The Link Pass-Through feature allows the media converter to monitor both the
fiber and copper RX (receive) ports for loss of signal. In the event of a loss of
an RX signal (1), the media converter will automatically disable the TX
(transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is automatically notified of the link loss (4), which prevents the loss of
valuable data unknowingly transmitted over an invalid link.
NOTE: An enable/disable switch allows the Link Pass Through feature to be
disabled. Link Pass Through may interfere with the Auto-Negotiation feature
of other devices in networks where there are two media converters installed in
series.
