Installing Office Cable
Office cables are installed in the ladder-type rack and are classified into the subscriber
cables and the digital trunk cables by the installation section. Follow the procedure below
to avoid cable concentration:
y Cables between adjacent racks should be installed behind the cable rack to prevent line
twist.
y Cables between distant racks should be installed inside the cable rack to prevent line
twist.
y Cables in distant racks of the same row should be installed inside the cable rack to
prevent line twist.
The subscriber cables and the digital trunk cables should be installed using the Quick
Distribution Frame(QDF) or Digital Distribution Frame(DDF).
