If someone tells you media conversion is a
commodity product that anyone can bring
to market, they probably haven't looked at
the extensive product suite offered by
Transition Networks. With the industry's
most comprehensive offering of full-
featured products, Transition's media
converters stand out as "the choice" among
industry IT professionals.

Generally, media converters are low-level
OSI model devices with no IP or MAC
addresses and therefore are transparent to
the network. This "transparency" makes
them very inexpensive and easy to use, but
also can make troubleshooting the network
very difficult. In an effort to overcome this
difficulty and to make media converters
"visible" to network managers, Transition
has designed their full-featured products to
include the most advanced features on the
market today.

Auto-Negotiation allows devices to perform automatic configuration to achieve the best
possible mode of operation over a link. Devices with this feature will broadcast their
speed (10Mbps, 100Mbps, etc.) and duplex (half/full) capabilities to other devices and
negotiate the best mode of operation between the two devices.

While the inclusion of this feature is beneficial, the ability to disable it is equally
beneficial. In the event of a non-negotiating end device trying to connect to a
negotiating device, the mode of operation will drop to the least common denominator
between the two devices (i.e. 100Mbps, half-duplex). Disabling this feature gives the
user the ability to force the connection to the best mode of operation when trying to
link with a non-negotiating device. Most Transition converters with Auto-Negotiation
will allow you to disable this feature.





Optimal link established automatically



Quick and easy installation



No user intervention required to determine best mode of operation

Link Pass Through is a troubleshooting feature that allows the media converter to
monitor both the fiber and copper RX ports for loss of signal. In the event of a loss of
RX signal on one media port, the converter will automatically disable the TX signal of
the other media port, thus "passing through" the link loss.
(see diagram below)





End device automatically notified of link loss



Prevents loss of valuable data unknowingly transmitted over invalid link
