The rack-mountable E-TBT-FRL-1200, E-TEL-FRL-1200, and
E-TBT-FRL-0600 series multi-port media converters with
LinkAlert™* allow
the network administrator of a large and complex network to extend the
distances between multiple sets of 10BASE-T and 10BASE-FL devices.
E-TBT-FRL-1200
(shown) Provides twelve (12) independent media converter
connections between Ethernet
™
over twisted-pair copper (twelve RJ-45
connectors) and Ethernet
™
over singlemode OR multimode fiber (twelve fiber
connectors of one type – selected, according to network requirements).
E-TEL-FRL-1200
(not shown) Provides twelve (12) independent media
converter connections between Ethernet
™
over twisted-pair copper (one 50-pin
Telco connector) and Ethernet
™
over singlemode OR multimode fiber (twelve
fiber connectors of one type – selected, according to network requirements).
E-TBT-FRL-0600
(not shown) Provides six (6) independent media converter
connections between Ethernet
™
over twisted-pair copper (six RJ-45 connectors)
and Ethernet
™
over singlemode OR multimode fiber (six fiber connectors of
one type – selected, according to network requirements).
*The LinkAlert™feature, enabled and
disabled using switches on the front of
the multi-port media converter, allows
each media converter port to pass link
faults between connected 10BASE-T
and 10BASE-FL devices.

COMPLIANCE INFORMATION
UL Listed
C-UL Listed (Canada)
CISPR/EN55022 Class A
FCC Regulations
This equipment has been tested and found to comply with the limits for a class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at the user’s own expense.
Canadian Regulations
This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on
the radio interference regulations of the Canadian Department of Communications.
Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables
aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.
European Regulations
Warning
This is a Class A product. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate measures.
Achtung !
Dieses ist ein Gerät der Funkstörgrenzwertklasse A. In Wohnbereichen können bei Betrieb dieses Gerätes
Rundfunkstörungen auftreten, in weichen Fällen der Benutzer für entsprechende Gegenmaßnahmen
werantwortlich ist.
Attention !
Ceci est un produit de Classe A. Dans un environment domestique, ce produit risque de créer des
interférences radioélectriques, il appartiendra alors à l’utilsateur de prende les measures spécifiques
appropriées
VCCI Class 1 Compliance
This equipment is in the 1st Class category (information equipment to be used in commercial and/or
industrial areas) and conforms to the standards set by the Voluntary Control Council For Interference by
Data Processing Equipment and Electronic Office Machines aimed at preventing radio interference in
commercial and/or industrial areas. When used in a residential area or in an adjacent area thereto,
interference may be caused to radio and TV receivers, etc. Read the instructions for correct handling.

Angleichung der Rechtsvorschriften der Mitgliedstaaten über Telekommunikationsendeinrichtungen
einschliesslich der gegenseitigen Anerkennung ihrer Konformität.

E-TBT-FRL-xx00 IN THE NETWORK
Each media converter port in the multi-port media converter operates
independently over one isolated twisted-pair copper/fiber-optic cable
link. The media converter port receives and transmits network signals in
either full-duplex or half-duplex, depending upon the network devices
to which the media converter port is attached.
NOTE: In Telco option (not shown), the 50-pin Telco connector
concentrates up to 12 UTP connections onto one connector. This
concentration of UTP ports is then broken out for connection to fiber.
RJ-45 CONNECTOR
Twisted pair connection requires two active pairs configured as straight
through and/or crossover. The two active pairs in an Ethernet™ network are
pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as blue/white
& white/blue, orange/white & white/orange) for the active pins.
NOTE: The multi-port media converter AutoCross™ feature allows either straightthrough or crossover twisted-pair copper cable to be used when connecting to
10BASE-T devices. AutoCross™ determines the characteristics of cable
connections to the media converter port and then automatically configures the
port to link up.
