CISPR/EN55022 Class A
T1/E1 Copper-to-Fiber
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.

USER’S GUIDE
Canadian Regulations
TRANSITION Networks T1E1-CF-01 series media converters encode and decode
T1 OR E1 signals over duplex fiber cables to extend the distance and transmission
reliability of high speed T1 and E1 data traffic.
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.

Twisted-Pair Copper Cable
Twisted pair connection requires two active pairs. The two active pairs in a T1/E1
network are pins 1 & 2 and pins 4 & 5. Use only dedicated wire pairs (such as
blue/white & white/blue) for the active pins.
