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.



Automatically detects and configures the twisted pair port on the converter to the correct MDI or MDI-X
configuration.



Eliminates an entire category of troubleshooting



No need to identify cable type—straight-through or crossover



No user intervention required to determine correct button / switch settings



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



Transition Networks's converters will automatically re-establish link in all network conditions.

Transition Networks's converters will automatically re-establish link when connected to switches if link was
lost. With other manufacturers' converters the user must reset the converter to re-establish the link.

Automatic Link Restoration allows the users to continue using Auto-Negotiation with Link Loss Notification
features. With other manufacturers' converters the user must disable Auto-Negotiation and hard set the link.

Automatic Link Restoration on Transition Networks's products allows users to continue using Link Loss
Notification feature activated in both directions. Many competitive solutions allow for Link Loss Notification
activation only in one direction. If Link Loss feature is activated in both directions, competitive products are
put in a "deadly embrace" and they cannot restore the link without resetting the converters.



No need to reset devices



Auto-Negotiation Enabled



Link Pass Through Activated in both directions
