DEFINITIONS
Alien crosstalk – electromagnetic noise (degrading performance) that occurs on a
cable that runs alongside other signal-carrying cables.
Building backbone cabling – cabling that connects a Building Distributor to a Floor
Distributor.
Building Distributor – the Distributor in which building backbone and campus
backbone cables terminate, cross-connect and inter-connect.
Category 5e (Cat 5e) - AS/NZS 3080 standard
Category 6 (Cat 6) – a cable standard for Gigabit Ethernet, backward compatible
with Category 5/5e - AS/NZS 3080. Cat 6 is designed for Gigabit Ethernet, 250 MHz.
This cable can carry up to 10 Gbps but only up to 50 metres. When used for
10/100/1000 mbps the maximum allowed length is 100 metres comprising 90 metres
of horizontal run to the patch panel and 10 metres between the panel and device.
Category 6A – a cable standard that has performance improvements around the
elimination of alien crosstalk compared to Cat 6. Cat 6A is capable of carrying
10GBASE-T for distances up to 100 metres and is rated at 500 MHz.
Certified Installer – Party or parties responsible for the supply, installation, testing
and warrantying of cabling systems.
Consolidation Point – Hardware providing interconnection between two installed
horizontal cables.
Floor Distributor – distributor in which the building backbone and horizontal cables
terminate, cross-connect and inter-connect.
Horizontal Cabling – cable connecting the floor distributor to a TO
Intermediate Distribution Frame – Rack/Enclosure for interconnecting data &
telecommunications cable between end user devices and a main distribution frame.
Main Distribution Frame –
PoE – Power supplied over Ethernet; typically refers to devices where dc power is
delivered via twisted pair cabling on the unused pairs, up to 15.4W
PoE+ - Provides up to 25.5 W of power over 2 cable pairs
UPoE – Universal Power over Ethernet provides up to 60 W of power over all 4 pairs
Rack/Enclosure – a lockable cabinet which houses equipment and cabling
Structured Cabling – Structured cabling brings all communications systems back to
centralised patch panels. Services connecting at a patch panel may include
telephone, data, alarm systems, distributed audio or TV, CCTV etc. One cabling
system supplies all. Structured cabling systems provide enormous flexibility and
manageability. Services can be patched locally without the need of Telco input.
(See Discrete Cabling below)

DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
Discrete cabling – where a separate cabling plan is used for each type of services.
E.g. a telephone would plug into a wall socket that could not be used for any other
service.
Wireless WAN - used by DoE in areas where cabled services are poor or do not
meet the Department’s needs. Wireless WAN is not something directed at users but
a system between two wireless systems. A beam from one wireless is aimed directly
at another usually by line of sight.
WLAN – Used for connecting users to a Local Area Network using wireless. A series
of Wireless Access Points (WAPs) are connected to the LAN in a given site and a
user’s device connects to a WAP.

SITE SAFETY
All contractors and visitors to DoE sites must comply with work, health and safety
legislation, Building Code requirements and the Agency’s policies and procedures.
All visitors to a Department of Education site must report to Reception to sign in and
are required to comply with all directions as given by the School/Site Manager.
Accredited Installers and Contractors shall also:
Report to the site contact for advice on local requirements for Workplace
Health and Safety, eg site specific induction, emergency procedures
(evacuation) and location of amenities
Inform the site contact and/or DoE IT Project Manager of any high risk
activities being conducted and the type and duration of work to be undertaken.
Examples of high risk activities include trenching, working at heights and
working near underground services;
Ensure that all work activities are carried out safely;
Restore the site to good working order (ie replace furniture, fittings, etc),
remove all waste and clean up any debris generated by their work activities.
For further Information please contact the Facility Services (Operations) at
[email protected]
Asbestos Register
An Asbestos Register is kept in a central area at each site such as Reception - all
contractors and maintenance workers MUST inspect the Asbestos Register before
works commence.
Expected Conduct
All Contractor personnel attending sites for any purpose are to wear the designated
Contractor uniform and carry approved identification at all times. In carrying out the
services, the Contractor shall at all times be mindful of the needs of the occupants of
the site and shall follow all directions given by the school/site manager.
Any visitor is required to act courteously at all times. This includes no smoking; no
consumption of alcohol or drugs on or in the vicinity of the site, no offensive language
or behaving in a threatening or dishonest manner.

DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
Security
A Working with Vulnerable People registration is mandatory, prior to commencement
of duty, for contractors undertaking ongoing work in schools, LINCs and other
Agency sites.
Noise and disruption
The contractor is not to undertake work which disrupts the normal conduit of
business without giving the school/site manager reasonable time to respond and
stipulate any conditions.
The emphasis here is on both sides being reasonable. It may be necessary to
arrange a more appropriate time to undertake the works.
LAN SWITCHES
DoE has standardized on Cisco communications infrastructure for its LAN
implementations.
For Schools
Switches can be purchased through the ITS online shop. IT staff can provide advice
around product suitability and recommendations to determine best ‘fit’.
For Contractors/Installers
Several Cisco switch models are currently available for purchase by the Agency.
Technical specifications including dimensions can be obtained from Cisco’s website.
Inormation Technology Services
Department of Education

DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
WIRELESS ACCESS POINTS (WAPS)
For Schools
The Agency uses an enterprise wireless network provided under the Networking
Tasmania contract. WAPs can be purchased through the ITS online shop. IT staff
can provide advice on the number and locations of WAPs for sites as well as lifecycle
management. Schools need to discuss their WIFI requirements with their local IT
support staff.
For IT Staff
Floorplans of coverage areas shall be submitted to Telstra by the ITS Networks
Team, to enable WAPs to be managed via Cisco Prime. Site predictions should be
undertaken in Prime to assist with proper placement of WAPs where coverage areas
have obstacles which may impede signal strength and reach. For larger sites where
required wireless coverage is more complex, Telstra can undertake an on-site
physical survey at a cost to the School which can be negotiated via ITS.
WAPs should be connected to PoE+ compatible switches. The ITS online shop
provides further information on feature sets of current model WAPs and their
requirements.
It is recommended that WAPs not be connected to multiple power sources (eg a
PoE+ switch and an injector) as this may cause the WAP and the upstream switch to
shut down. In this instance 802.11ac enabled WAPs should continue to connect to
standard PoE switches without the use of a power injector.
The use of outdoor WAPS should be discussed with ITS as additional network and
physical requirements are necessary to support this infrastructure.
For Contractors/Installers
Where new cabling is required for WAP installations it shall be a minimum of 2 x
Cat6A runs. A labelled double outlet at the WAP end shall be provided - this will
enable the WAP to be repositioned, if required, via the flexibility of a patch lead. Note
that new cabling installations must be tested and installed by a Certified Installer.
There shall be a minimum clearance of 30 cm from any surface of the WAP to nearby
persons and where the WAP has integrated antennas it shall be mounted horizontally
unless an appropriate bracketing system is used. It is recommended that access
points and wireless network antennas be mounted in elevated positions, at or near
typical ceiling height where possible. This is to enable ease of access (taking OH&S
into account) and to minimize the potential for both radiation exposure and
vandalism.
Inormation Technology Services
Department of Education
13
DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
At a minimum where external WAPs are mounted on roof tops or other exposed
locations (which may be subject to lightning strike) each antenna will require earthed
lightning protection.
Please refer to the list of Australian and International Standards referenced in this
documentation together with the Manufacturer’s instructions as a minimum accepted
standard for Wireless mounting standards within the Department.
DATA AND GENERAL CABLING RULES

Cabling must be fully supported by independent cable support systems and shall not
be laid onto other services or ceiling surfaces. All cabling shall be secured to support
structures via a hook and loop style cable ties (Velcro or similar).
Cables must not be over tightened. If this occurs, the performance of the cable may
be affected so that specifications cannot be met.
Cables must be anchored immediately before and after a bend in a cable or loom.
This ensures that the minimum cable bending radius is maintained.
There shall be no more than 32 4-pair cables or equivalent in a loom, for Class D and
below. For Class E and above and FTP, no more than 24 4-pair cables. These
recommendations also apply to catenary wire support systems.
Anchoring may not be required where cables are installed horizontally on a
continuous support, such as a tray, where disturbance or possible damage is not
likely.
Horizontal Cabling at the Work Area
All work area patch leads shall be selected and available in varying lengths such that
the Horizontal cable length is within 100 metres.
Telecommunications (Wall) Outlets
As a minimum requirement double wall outlets shall be installed. This provides
flexibility in the event of a cabling failure.

e.g. Rack “A” Rack Unit (RU) “27” Socket 7 will be labelled as A-27-7.
Telecommunications outlets must be labelled with the outlet number (which
corresponds to its appearance at the distributor) and those additional identifiers
which may be necessary to uniquely identify the outlet at the respective premises.
Cross-connect positions for horizontal cabling must be labelled to correspond to the
labelling of their respective telecommunications outlets.
Distributor Cabinets, Racks or Frames
Distributor cabinets, racks or frames must be fitted with a large label readily visible
and legible from a range of at least 2 m showing the distributor identification. The
sheath of backbone cables linking distributors must be labelled using a wrap on label
or affixed tag at each end (distributor, splice point or underground joint) detailing the
cable type, capacity, remote distributor and termination appearance and local
distributor and termination appearance.
Consolidation points
Consolidation points must be fitted with a label indicating the maximum cable run
length from the consolidation point to a connected telecommunications outlet. Multiuser telecommunication outlets must be fitted with a label indicating the maximum fly
lead length which may be used to connect to terminal equipment.
Fibre Optic Patch Fields
Fibre optic patch fields must be labelled with laser source warning signs to AS/NZS
2211. Where mixed multimode fibre core sizes are used on the same site (for
example 62.5/125µm and 50/125µm), a means of distinguishing the core size must
be provided at the connector and on patch cords to prevent mismatched fibres from
inadvertently being patched.
Labels must be of a size, colour and contrast to be readily legible and have a useful
life equal to or greater than that of the component being labelled. Machine printing or
engraving with a minimum text size of 10 point (or 2.5 mm text height) is
recommended for outlets and distributor appearances. Distributor identifiers should
be highly visible and have a minimum text height of 10 mm.

OUTDOOR WIRELESS BRIDGE INSTALLATIONS
When connecting buildings via Wireless Bridges, the Manufacturer’s Guidelines must
be followed and consideration given to adequate lightening protection and the
appropriate positioning of radio and antenna equipment.
COMMUNICATIONS RACKS, CABINETS AND
ENCLOSURES
Overview
Communications cabinets and/or enclosures have a requirement to house racks that
may comprise patch panels, cable management, switching equipment, servers, UPS,
security systems, etc. It is therefore vital that racks, cabinets and enclosures are
chosen with this functionality in mind.
A typical rack layout is depicted in Appendix A. Note the following minimum
requirements for green field sites and new rack installations:
 When planning for new rack deployment ensure an additional 30 – 40% of RU
space is free for future growth
 Racks exceeding 18RU in size must be floor mounted
Where running PoE or PoE+ the bundle size is limited to up to 40 cables per bundle
due to heat dissipation. This must be strictly adhered to where small diameter patch
leads are used in a PoE environment.
Safety of Installation
In the performance of any cabling work, in general the cabling provider should ensure
that—
 End-users are protected from personal electrical contact with any
voltage/service other than SELV and from any exposure to laser radiation;
 Cabling providers are protected from accidental personal electrical contact with
LV telecommunications circuits, LV power and HV circuits or accidental
exposure to hazardous laser radiation;
Inormation Technology Services
Department of Education
19
DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
 Cabling providers who are required to access, install or maintain LV
telecommunications circuits, are protected from accidental personal electrical
contact with LV power and HV circuits;
 Licensed electrical workers are protected from accidental personal electrical
contact with any telecommunications circuits or accidental exposure to
hazardous laser radiation; and
 The creation of any general safety hazard is avoided, e.g. tripping, falling or
bodily impact with a protruding object.
Note: end-users are all persons other than persons performing cabling work,
including persons who do not actually use the telecommunications service (e.g.
casual visitors, cleaners). End-user contact with SELV circuits should be prevented
where practicable.
Note: Provision is made in this Standard for cabling providers who are suitably
qualified or licensed to access LV telecommunications circuits, LV power or HV
circuits.
Cabling providers must comply with relevant Commonwealth, State and Territory
OH&S requirements including, but not limited to, Building Code requirements.
Cooling and Airflow Requirements
All server racks are to be fitted with front mesh doors (and rear where possible) and
fans installed to the roof of the server rack to allow for adequate air flow, ventilation
and heat dissipation.
Security
For the purpose of this document, an ‘enclosure’ includes a closet or room provided
for the express purpose of housing the MDF, in which case the closet/room door is to
have provision for securing with a key, lock or tool if the MDF doesn’t.
Note The building owner, manager or occupant is responsible for the security of the
MDF. The MDF should be adequately secured against vandalism and access
unauthorised persons but reasonable access should be given to carriers, carriage
service providers, cabling providers and other authorized personnel as required.
All racks must have lockable doors and removable and lockable sides. Ladder racks
or open racks may be installed to lockable rooms that do not have general access to
ensure adequate security.
Inormation Technology Services
Department of Education
20
DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
Positioning of enclosures/cabinets and racks
In order to avoid the need for ladder access to racks as a guide racks should be
positioned no higher than 2 metres to the top of the rack from the floor.
The lowest terminal or socket should not be less than 350 mm above finished ground
or floor level.
Specifying Racks & Cabinets
Refer to Appendix B for further information on rack categories.
Wall Mounted Racks
Wall mounted racks used by the Agency have a maximum depth of approx. 700 mm
(600mm rack + 100mm hinge). Wall mounted racks are available in 6, 12 & 18 RU.
Racks which are larger than 18RU must not be wall mounted under any
circumstances.
Floor Mounted Racks
Floor mounted racks come in two size categories – full height or half height.
Full height racks are 42-45RU in size with an approximate depth of 1000mm. Full
height racks may contain core switch equipment, servers and UPS together with
other equipment. Full height racks may also contain network infrastructure only
without servers. These are sometimes referred to as communications or network
cabinets.
Half height racks used by the Agency are generally 22-27RU in size with two depth
categories these being approx. 1000mm and 800 mm. Server racks should be
approx.1000mm deep while half height communications racks may be 800mm deep.
Compact Enclosures
At times it may be necessary to use compact enclosures where a horizontally flush
mounted cabinet is required. In this case, a Panzone PZAEWM3 or equivalent must
be used. These enclosures offer 6RU – 3RU for inactive equipment, i.e. patch panels
and 3RU for active equipment, i.e. switches. Note that these enclosures must be
lockable.
Inormation Technology Services
Department of Education
21
DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
Consolidation Points
Consolidation Points (CP's) may be used in special circumstances, eg to re-locate a
rack to a more suitable location. There shall be no more than 1 CP installed per
horizontal cable run. Note that Consolidation Points:
 must be an in area that is easily accessible for fault finding
 must be within the 90 metre range for test limits
 must be installed in a manner that has the capacity to be secured and locked
Cable Management
For racks where horizontal cable count exceeds 200, a DoE designed rack layout is
required.
In large racks (24 RU and over) or exceeding a horizontal cable count of 200 vertical
cable management rings must be large enough to cope with the patch cabling to be
run. As a rule of thumb allow for 2 patch cables per user in office areas and 2 per
user in classroom environments (this should provide enough spare capacity to allow
free movement in the vertical).
In smaller racks (less than 24 RU) the use of Velcro straps for vertical cable
management is acceptable.
Vertically mounted enclosures may be used where 3 or less patch panels and only 1
or 2 switches are required. This type of enclosure mounts the switches vertically and
provides a much more efficient use of wall space.
Note: Plastic or metal cable ties must not be used to tidy patch cables under any
circumstances.
Patch Panels
24 way patch panels per 1 RU with fully populated sockets are to be used in all DoE
racks. Patch panels shall be provided with integrated rear cable management units
so as to provide cabling support. Where this is not possible then an alternative form
of cable support should be provided. Refer to Appendix A for cable management and
layout specifications.
There is now available a new small diameter patch cable offering which utilizes 28
AWG conductors. This allows for higher density installations and better cable
management, improved air flow, flexibility and a tighter bend radius of 15mm. It is
recommended where possible that small diameter patch leads are used throughout
rack installations.
Inormation Technology Services
Department of Education
22
DATA COMUNICATIONS CABLING STANDARDS & SPECIFICATIONS
Different patch lead colours shall be used to differentiate DoE telecommunications
services according to the DoE Patch Lead Colour Code (refer Appendix B – Patch
Lead Colour Code chart).
Power to Racks and Patch Cabinets
All power is to be contained within the inside of the data rack. All protective earthing
is to be of 6mm cable size.
All electrical work must be undertaken by a licensed practitioner. It is mandatory by
law to RCD protect any new power circuits installed on any premises that allows an
individual to plug in an appliance (refer RCD Protection – AS3000)
UPS
To calculate UPS requirements, formula is as follows:
Volts x Current x Number of Appliances x 1.2 = VA
Edge Switch and Non Critical Racks
Edge Switch and Non Critical Racks will consist of a front mounted 5-8 way
horizontal power rail to be fitted. A capture plug may need to be installed to prevent
dislodgement from power source.
Server and Core
Power requirements consist of a 10-22 way vertical power rail in conjunction with a
15 amp dedicated power circuit with UPS backup.
