What are these network cables ?
Which regulatory body regulates the cabling industry ?
Cabling Provider Rules (CPRs)
Define Network boundary.
The point of connection between the carrier’s (e.g. Telstra, Optus, Vodafone etc.) network and the customer’s network.
Define customer cabling.
Any cabling on the customer side of the network boundary.
Define Cabling work.
Installation, connection or maintenance of customer cabling.
What is Australian Communications and Media Authority (ACMA) ?
ACMA is a government agency responsible for the regulation of broadcasting, the internet, radio-communications and telecommunications
List some of the responsibilities of ACMA.
- Developing technical standards and monitoring compliance.
- Help with codes of practice and monitoring compliance.
- Monitoring the performance of carriage service providers (e.g. Telstra, Vodafone etc.).
- Advising consumers on their rights and safeguards.
- Managing the delivery of services to people with a communication impairment.
- Overseeing the cabling registration system.
What are the three types of cabling registrations ?
Open Registration
Restricted Registration
Lift Registration

What is Restricted Registration ?
What is Lift Registration ?
List 5 Cabling endorsements
List 5 ACMA accredited cable registrars
Why must network cables be segregated from power cables and what is the minimum distance ?
To prevent the power cables from inducing voltage into the network cables.
Parallel runs must be minimized where possible.
Minimum distance = 50 mm

Name the following cable hauling equipment.
How does standing waves occur in cables and how to avoid it ?
List the type and application for the following COAX connectors
What does the following indicate ?
A reading of infinite ohms (i.e. an open circuit) indicates that there are no short circuits (S/C) between the shield and the inner conductor. Alternately, a low resistance reading indicates a short circuit.
What does the following indicate ?
A continuity reading (i.e. a short circuit) indicates that both the shield and the inner conductor are electrically continuous. A high resistance reading indicates a problem, for example a break in the inner conductor.
