FT1/FE1 Cables
Introduction
The FT1/FE1 daughtercard requires one of the following cables to connect to the
T1/E1 network:
• RJ48-to-RJ48 twisted pair cable (provided with FT1 daughtercard) to connect
to a T1 network.
• RJ48-to-RJ48 twisted pair cable (provided with FE1 daughtercard) to connect
to a E1 network having 120ohm line impedance. ETSI-TBR-013 requires that
this cable be constructed of solid conductors of 0.4mm to 0.6mm.
• 2 BNC-to-BNC 75ohm coaxial cables (not provided) to connect to an E1
network having 75ohm line impedance.
