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.

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

All chassis-based converters from
Transition Networks® can be managed
through SNMP. Now, select stand-alone
products can also be managed through
SNMP when used in conjunction with a
chassis based converter. While chassis
based products are generally placed in
the telecommunications room, stand-
alone converters are generally placed in
remote locations away from network
administrators. Remote in-band
management over fiber allows
administrators access to the remote
device to check status and
enable/disable features or the device
itself.

management of media converters





Select Transition Networks products are equipped with Loopback. This feature puts a
converter in a special mode that enables the device to loop back the signal from the RX
port to the TX port on either media for testing and troubleshooting purposes. Test
signals from a tester (Firebird, etc.) can then be inserted into the link and looped back
as received by a device to test a particular segment of the link (i.e. copper or fiber).
Loopback can be either local or remote depending on the location of the converter in
the link.

Some converters have separate copper and fiber loopback functions that can be
enabled separately, while others will loopback both copper and fiber at the same time
when enabled. Please refer to the specific product page for details.





Allows network diagnostics from local or remote location



Quickly pinpoints problem areas of end to end link by testing a particular segment
