The Telecommunication Act was passed in 1989 by the Australian Government.

This act deregulated the telecommunications industry enabling licensed providers to undertake cabling work formerly undertaken by Telecom/Telstra.

The ACMA responsibilities include:-

Promoting self-regulation and competition in the while protecting consumers and other uses.

Fostering an environment in which electronic media respects community standards and responds to audience and user needs.

Managing access to the radio-frequency spectrum including the broadcasting services bands.

Representing Australia's communications and broadcasting interests internationally.

The ACMA’s role in relation tocabling providers is in the

registration system

inspections

imposing fines.

Categories of requirements

This standard contains normative and informative elements. Normative elements (mandatory requirements) are indicated by the words "shall" or "shall not".

All other elements are informative.

AS/ACIF TS 009:2006 Rule 4.2 Pg 23

Supervision of unregistered cabling provider

If a registered cabling provider supervises an unregistered cabling provider, the registered cabling provider must ensure that:

the unregistered cabling provider is supervised , at all times while performing cabling work, by a registered cabling providing:

each registered cabling provider who supervises that cabling work accepts full responsibility for the standard of the work performed under the provider's supervision;

all work performed under supervision complies fully with:the competency requirements mentioned paragraph 3.1 (2) (a); andthe Wiring Rules

Telecommunications Cabling Provider Rules 2000 Rule 4.4 Pg 9

The 10 CPRS are All customer cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabling provider.

Depending on the cabling work performed, cabling providers must obtain either an Open, Restricted or Lift Registration that meets ACMA's training competency requirements.

All ACA cabling licences in operation under the previous regulatory framework expired on the 2nd October 2005, and since that date all former licence holders have been required to be registered with one of the five cabling registrars accredited by the ACMA.

Cabling providers are required to notify their registrar of any change of contact details within 21 days.

Cabling providers must comply with the AS/ACIF S009:2006 Installation Requirements for Customer Cabling (wiring rules). The wiring rules detail the minimum requirements for the cabling installations to ensure that network integrity and the health and safety of end users , other cabling providers and carrier personnel is protected.

Cabling providers are required to install only cabling product (including cable) and customer equipment that complies with the requirements of the Labelling Notice.

Cabling providers must at the completion of each cabling task provide the client with a job sign-off form, known as a Telecommunications Cabling Advice form(TCA form).

Registered cabling providers must directly supervise an unqualified person's work. This is known as the Supervisor Rule.

Under the Supervision Rule, a qualified cabling provider must accept full responsibility for work done by an unqualified person and ensure that it fully complies with the Wiring Rules, including signing the form.

Cabling providers must provide all reasonable cooperation and assistance to ACMA inspectors cabling auditors. Cabling providers can be subject to fines if they do not abide by their registration conditions.

Registration

Under cabling provider rules, there is mandatory and voluntary registration.

Mandatory registration covers the Open, Restricted and

Lift categories.

Voluntary registration covers higher level skills those previously recognised through endorsements, such as

optical fibre and data cabling.

See Hampson page 448 for prerequisites for registration

Open cabling work covers all types of cabling work.

Restricted cabling work covers a restricted range of cabling work in residential and small business premises.

Lift cabling work includes telecommunications cabling in relation to lift installations.

Registrars There are 5 ACMA accredited registrar:-

Australian Cabler Registration Service (ACRS)

Australian Security Industry Association Limited (ASIAL)

BICSI Registered Cablers Australia PTY LTD

Fire Protection Association Australia (FPA Australia)

TITAB Australia Cabler Registry Services (TITAB)

Inspection of cabling work The ACMA conducts investigations into written complaints by the public about unsatisfactory cabling work to enforce compliance rules. The carrier may inspect work to ensure that it satisfies the industry regulator's standard for network integrity, personal safety and proper network functioning.

If a carrier inspection reveals a threat to safety or proper functioning of the network, then it may refuse to connect some or all services.

Segregation The separation of customer cabling from electrical hazardous services is required to avoid creating a dangerous situation resulting from mechanical damage of communications cables. Therefore segregation of telecommunications cabling from power is important for the general safety of customers, cabling providers and carrier staff. Both the AS/ACIF S009:2006 and AS/NZS 3000:2007 require segregation of power and telecommunications cables and their terminations by appropriate means.

Earth Potential RiseAs the earth has some resistance, a current flowing through the earth will cause a potential difference between

two points in the ground. This is known as earth potential rise (EPR).

Low Frequency Induction It is possible for 50Hz to be induced in the metallic conductors of communications cables where they

run parallel to high-voltage power lines carrying low frequency (50 Hz) currents.

Surge suppression Telecommunications cables are prone to over-voltage from external and internal sources. Techniques for protecting telecommunications equipment and personnel from over-voltage include the following:-

InterceptingClamping or clippingsShuntingInterruptingIsolation

Gas arrestors are the main form of primary protection. A gas arrestor is a gas discharge device that conducts when the voltage between its terminal exceeds a predetermined value.

Hampson Pg 455 also AS/ACIF TS009:2006 rule 20.20.2

Surge suppression –The effects may range from minor noise to disruption of the service, note avoid using telephones during thunderstorms.

Surge suppresses reduce the risk of excessive voltages that may cause damage to telecommunication networks or equipment. e.g. lightning strikes, voltages surges or spikes

Devices for protection must connect to a compliant earth reference through a green/yellow cable Clause 20.20 AS/ACIF TS009:2006

Cable distribution devices

A distributor is a connection device that provides for cross-connection of cables using jumpers or patch cords.

AS/ACIF TS009:2006 clause 3.1.32.

The distributor at the network boundary is the main distribution frame (MDF).

General regulatory requirements Cross -connection should match or exceed the category rating of the installed cabling systems. Clause 12.3 of AS/ACIF TS009:2006 requires the cabling provider to supply sufficient cabling records relating to the cabling to enable cables and cross-connections to be correctly identified and connected, the cabling records must be legible and updatable. Distributors located outdoors must have a minimum rating IPX3 and installation must not degrade this rating. See AS/ACIF TS009:2006 rule 12.5 Pg 45

MDF An MDF provides, or is intended to provide, an electrical termination point for a carrier's lead-in cable. AS/ACIF TS009:2006 rule 3.1.56 Network boundary is the point which is deemed to be the boundary of a carrier's telecommunications network for determining whether cabling or equipment is "customer cabling" or "customer equipment" for the purpose of technical regulation under Part 21 of the Telecommunications Act.AS/ACIFTS009:2006 rule 3.1.57

MDF location The location of the MDF must be in or on a building. Also to be close to the electrical switchboard to facilitate earthing and equipotential bonding where required.

When installing an MDF provide the minimum clearances as specified in Appendix D of AS/ACIF TS009:2006

Indoor cabling

Two insulated copper conductors form the basis of telephone service to the customer’s premises.

Twisting insulated wires together forms a twisted pair.

This twisted pair is the pathway for the signals between the customer’s telephone and the carrier’s exchange.

Indoor cable usually has a cream coloured PVC sheath over PVC insulated wires. They may be:-

UTP - unshielded twisted pair constructionFTP – overall foil shielded twisted pair

Separation The main reason for maintaining separation from low-voltage cables is to minimise the risk of accidental penetration of both cable by nails, screws, drills and the like.

For this reason we have a minimum standard of air separation of 50 mm.

Another standard of separation is a barrier of a durable insulating material or earthed metal between both conductors, also in conduit, cable trunking / ducting and cable skirting is satisfactory. See clause AS/ACIF TS009:2006 16.3

Bearer/Rafter/Joist

LV Power Cable

Telecommunications Outlets There are several types of T.O. The most common is the 600 and the RJ series (modular connection).

Installations In damp areas, bathrooms, laundries and the like the T.O. must be outside the damp restricted area zones as per AS/ACIF TS009:2006 appendix A and AS/NZS 3000:2007.

Underground cabling

The depth of laying for cables installed under a public roadway or footway is 450mm. In other areas the minimum depth is 300mm.See clause AS/ACIF TS009:2006 18.6.

A compliant conduit, marked as communication pipe, or has a white marker tape laid 100mm above the unenclosed cable is a requirement under the AS/ACIF TS009:2006 rules.

Aerial cabling

Aerial cables often incorporate a strong support wire known as the “integral bearer”.

The bearer wires must insulated from any conductive pole or structure carrying an aerial power line.See clause AS/ACIF TS009:2006 19.5.8.

They must be insulated or shrouded to prevent accidental contact by a power-line worker and must not connect to earth.

Clearances Clause AS/ACIF TS009:2006 19.2 species the minimum clearances for aerial cables. 2.7 m over private property not traversed by road vehicles

3.5 m over any residential driveway

4.9 m over any commercial or industrial driveway or private road

Earthing The types of earthing found in a telecommunications installation are:-

Equipotential bonding

Communications earth terminal

Communications earth system

Telecommunications reference conductor

Telecommunications functional earth electrode

Heritage Sites and buildings The term heritage maybe broadly defined as “the possessions, traditions or conditions that have been passed from one generation to another.

Queensland Heritage Act 1992

Installation

Cabling work in a heritage-listed is usually specialised work and should only proceed on the advice of a specialist in that field.

Permission may be required from the relevant authority. This must be applied for in writing, on the correct form and before any work can be started.

Fire regulations and cable installations

It is essential that a cable installer be aware of how the installation of cables and support systems may affect the fire safety of a building.
