o far 2005 has been very successful and
eventful for us in the Australian market. We
have been able to keep the momentum going
with consistent sales growth and increased
market share. Independent market research
shows ADC KRONE is Australia’s preferred
structured cabling provider, surpassing competitors
in quality and availability. Additionally, as the
combined entity we now are the major network
infrastructure supplier to both major network
operators.
The eventful start to the year has focused on
introducing our new go-to-market brand, ADC
KRONE, and showcasing our new global look and
feel. You may also have seen our first series of
advertisements highlighting the strengths of the
combined entity - ONE COMPANY. Endless

t ADC KRONE, we are looking at the best
ways to service you, our valued customer.
Part of this is to simplify our solution offerings. In
the past you would have heard of the TrueNet
brand but now under the ADC KRONE banner

this means something very different.
Our previous solutions were referred to as
Premis
NET
®
Global Leader and Premis
NET
®
Enterprise solutions. Our Category 6 solutions
used TrueNet technology, an engineered
solution to ensure near-perfect impedance
matching to eliminate errors caused by the
cabling system in the network.
TrueNet has now become the global brand for
ADC KRONE’s complete range of Structured
Cabling and Data Centre products. The new
TrueNet is a marked improvement to the trusted
PremisNet® solutions. It combines KRONE’s
diverse copper solutions portfolio with the ADC
group’s unique fibre connectivity, cable
management and additional complementary
solutions.
Now that we have combined the ADC and
KRONE product portfolios, the TrueNet solution
truly is a comprehensive set of products
for all areas of your
network. From the
Campus backbone to
the building entrance
and all over the building

itself, TrueNet is the one
solution you need.
PROVEN COPPER
SOLUTIONS
TrueNet covers our tried and
proven Category 5 products
that have been on the market
since 1994. It covers our
Category 6 products that are
the only products covered by a
genuine throughput warranty.
And now it covers our
CopperTen
™
solution, the first
copper UTP solution to carry 10 Gigabit
transmission over the full 100 metres.
IMPROVED FIBRE SOLUTIONS
We utilise state-of-the-art manufacturing facilities
at Berkeley Vale, NSW. More than 90% of all fibre
cable sold by ADC KRONE is manufactured in
Australia.
Whether it is Single-Mode, OM1, OM2 or OM3
Multimode cable, whether it is ST, SC, LC, MTRJ
or FC connectivity, whether it is 100 metres or
100,000 metres, TrueNet has the right fibre
solution.
NEW COMPLEMENTARY SOLUTIONS
The new TrueNet includes our recently
developed Power over Ethernet controllers.

These Midspan controllers are a cost effective
way to inject power to remote devices over your

n expansions of existing facilities or moves into
new spaces, careful thought is usually given to
colours and decorative features. When it comes to
the structured cabling system, however, the
aesthetics of the components are often not
considered. So while space planners argue over
carpet choices and wall art, the decision criteria
for physical layer projects is normally limited to
functionality and price - which makes sense
because most brands of cable managers, cable,
and patch panels offer a similar appearance and
performance within defined requirements.
Decisions based upon function and price also
make sense because the structured cabling
system is usually hidden from view with cables
behind walls and within Telecommunications
Rooms (TRs).
However, as technology has become a more
integral part of business today, companies are
increasingly considering display of technology an
important aspect of the corporate persona. For
these companies, the voice and data
infrastructure becomes an integral part of the
overall space design where decision criteria now
reaches beyond functionality into the aesthetic

attributes of the structured cabling system. From
law firms to ISPs, rows of equipment racks are
now behind glass walls in reception areas. TCs,
TRs, and ERs have moved from confined or
custodial closets to more central and visible
locations.
The drive for aesthetics in the structured cabling
system has resulted in an unexpected benefit -
aesthetically pleasing designs have actually
improved the reliability and usability of the
network. It appears that aesthetics deliver a dual
benefit for the cabling infrastructure: beauty that
is not a beast to manage.
NEW METHODS FOR SHOWCASING
TECHNOLOGY
CNET regards cabling, TCs, and server rooms as
key design elements. As a result, on this project,
all horizontal cabling (specified Category 6 for
voice and data) is exposed, using orange and grey
to match corporate branding colours. Orange
horizontal cables are also exposed on polished
aluminum ladder racks up and down hallways.
BEAUTY AND THE BEAST
The appearance of a structured cabling system is not often
considered. John Schmidt uncovers its potential beauty.

Server Rooms (Equipment Rooms) feature glass
walls with orange spotlights pointed on
equipment racks. And on each of the six floors,
there are three “cages” situated among
workstations, with specially built metal sliding
panels for access and open viewing. (See Figure
1). It is these cages that required the most
thought in the overall structured cabling design
because they are entirely visible throughout each
floor and have the most potential to look bad if
moves or changes create a jumble of patch cords.
(See Figure 2).
The design committee settled upon this design
that had already proven its ability to maintain a
long-term, orderly appearance. The design called
for angled ports on patch panels with half of the
ports facing left and half facing right. In addition,

horizontal trays were eliminated in favour of
vertical cable managers providing horizontal
support as well as a more high tech appearance
than traditional vertical rings. This combination of
angled ports, no horizontal trays, and vertical
cable managers sweeps patch cords directly into
the vertical cable managers mounted on each side
of each rack - offering a striking effect. (See
Figure 3).
“We knew each vendor was certified for
Category 6 and could do the job for us,” said Don
McGill, Director of Client Services for CNET.
“However, when we saw how eliminating
horizontal trays and angling ports on patch
panels really forces technicians to route patch
cords into the vertical cable manager, we saw
something entirely unique among the vendors
who presented to us. We immediately knew this
was a design that would maintain a good
appearance,” he said.
USE OF NON-TRADITIONAL METHODS
Choosing vertical cable managers and patch
panels with angled ports in lieu of a system of
vertical rings, flat profile patch panels, and
horizontal trays delivers multiple, intertwined
benefits, according to Garry Schroeder, RCDD,
Project Engineer with Parsons Technologies in
Minneapolis. Schroeder implemented the angled
port/vertical cable management system at client
sites over the last couple of years, including

Dorsey & Whitney LLP, Watson Wyatt, and
Riverpath Medical Clinic.
“Horizontal management never really gets used
properly because it can be so time consuming,”
said Schroeder. “Methods that use horizontal
cable support trays require a lot of extra steps
that busy people might not take. Short cuts that
bypass horizontal trays and route patch cords in
all directions end up with racks that are a sloppy
Figure 2: Upper and lower crossover managers enable
connection of ports on opposite sides of the bay while
maintaining an orderly appearance.
However, as technology has become a
more integral part of business today,
more companies consider display of
technology an important aspect of the
corporate persona.
mess and much harder to manage,” said
Schroeder.
With vertical cable managers and angled
panels, the time required for moves, adds and
changes is greatly reduced. With this system,
patch cords are brought to one side, fed into the
vertical cable manager, and then routed back out
to another patch panel without having to weave
patch cords through rings and trays. These
activities take less time to manage and, by
actually encouraging order and symmetry in
racks, still maintain a neat appearance even
through rearrangements and additions to the

network.
BEAUTY PAYS OFF IN THE LONG RUN
CNET managers never dreamed that a design that
encouraged order instead of chaos in
telecommunication spaces would also pay long-
term dividends in terms of reduced technician
time.
“The design really improves the productivity of
our staff by adding simplicity to the network. It is
easy for us to determine connections, trace and
remove patches, and make changes - all without
causing a mess. For us, the design has become
more than just visually appealing. It has also
created a physical layer that is easier to work on.”
said CNET’s McGill.
In evaluating structured cabling products,
McGill and his team saw added benefits of the
angled ports/vertical cable manager system,
including increased rack density, improved access
for technicians, and enhanced protection of patch
cords due to slack managers and covers for the
vertical cable managers. However, the best payoff
came when CNET finally moved into the new
facility. Given that CNET employees had come
from eight different buildings with different
layouts and decorations, employees offered
favorable reviews on the design of the interior
workspace, especially the integration of such
technology elements as the structured cabling
system.

“We are a technology company, so we felt it
was important that all design elements convey a
high tech feel to the office,” said McGill. “When
employees feel good about coming to work,
everyone wins.”

espite initial predictions, 10Gig UTP is
happening now, with over 70% of ADC
KRONE 10Gig sales already going into the
horizontals of everyday companies.
When we first demonstrated, back in
November 2003, that 10 Gigabit/s UTP cable
could not only be designed it could actually be

manufactured, we knew it was going to be big.
By the time we launched the full CopperTen™
structured cabling system in March 2004 we’d
already installed a 70 kilometre/2,000 patch-port
data centre for an international bank and we
were forecasting take-up of the system in 2005 -
predominantly for data centres.
We were forecasting the uptake in data centres
first because of a number of factors. They have
high bandwidth requirements, leading the
workplace environment by orders of magnitude.
Data centres cost millions and, of course, you only
get one chance to cable them out. The extra cost
of 10Gig UTP copper over standard Cat 6 is very
small in the overall scheme of data centre costs -
but it does offer some significant advantages over
fibre in that currently available 1Gig NICs
(Network Interface Cards) are a fraction of the
price of their fibre counterparts and a UTP copper
approach allows legacy equipment - servers,
switches and routers with 10/100/1Gig interfaces
- to be used initially and easily upgraded when
10Gig UTP devices become available.
We were also sure, that we’d see history repeat
itself exactly as it did with Cat 5, Cat 5e and Cat
6 - i.e. that many users would start to install
10Gig UTP systems well before the standard is
ratified. But we were forecasting late 2005 or
2006 for the uptake to start in horizontal
developments. However, now that we’ve got

significant sales and installation experience under
our belts, and helped in the USA by our new ADC
parentage, we’ve seen a massive difference in the
sales mix from our earlier forecasts.
In fact, by the close of 2004, over 70% of
CopperTen
™
10Gig UTP sales have been for the
horizontal. And they’re being deployed
everyday in organisations! So permit me to
predict now, with the confidence of experience,
that 2005 is going to be the year of 10 Gigabit/s
UTP copper.
All of the arguments we’ve heard in the media
and at conferences such as “well, really Category
7 is the only solution to use for 10Gig because it’s
standards compliant” and “a screened solution
will be technically superior” have been resolutely
thrown aside, by none other than the people with
the money - your customers.
What I find particularly fascinating, and which
underlines my new forecast, is that the IT
managers who have already bought our 10Gig
UTP solution must have had their budgets signed
off early/mid 2004 - for Cat 5e and Cat 6 systems.
Yet, they have all been so utterly convinced of
their need for the future-proofing that 10
Gigabit/s gives (and of course it’ll be 7 to 12 years
before they get another chance to re-cable) that
they’ve almost all gone back to their boards to

argue for an additional 20% extra budget in order
to put in 10Gig UTP. The argument for 10Gig must
THE 10GIG MARKET HAS CHANGED!
We all know that 10Gigabit/s copper is coming in a year or two.
We thought it would find application only in data centres at first.
Kevin Anderson of ADC KRONE says we’re very much mistaken.
What makes 10 Gigabit/s UTP systems so
attractive is that it is not a new
technology; it’s a progression of a tried
and trusted one.

be very compelling, because they have convinced their boards and
been given the extra money.
It’s a fascinatingly broad spectrum of companies and
organisations, which are putting in 10Gig UTP. There are
universities in the USA, UK, South Africa and Slovenia - all deploying
CopperTen in the horizontal. Others include a US law firm, a UK
spectroscopy manufacturer, US and Indian consultancies. Then
there is an exciting application for one of the world’s leading
animation studios as well as an aerospace company which have
both gone 10Gig.
These are just some of the wide spread of organisation types that
are deploying 10Gig UTP - and yes, over 70% of the orders are for
horizontal deployments! So ADC KRONE’s message for 2005

continues to be this - “It is the market, and not technologists that
decides which system to adopt”.
We’ve pointed out all along, that well over 80% of the world is
UTP-centric. In these countries, networks are run and managed by
people who understand UTP copper. Networks are installed by
engineers who know how to install UTP copper. They’ve all been
brought up on Cat 5, Cat 5e, Cat 6 and of course the ubiquitous
RJ-45 plug and jack.
What makes 10 Gigabit/s UTP systems so attractive is that it is not
a new technology; it’s a progression of a tried and trusted one.
Which means it is planned, installed and managed in very much the
same way. It delivers ten times the data-throughput at a marginal
extra cost and it’s very low risk because it’s fully backward
compatible with Cat 6 and Cat 5e.
In conclusion, 10Gig copper is now firmly 10Gig UTP - because
your customers say so. And 2005 is going to be the year of 10Gig
UTP in the horizontal, not just the data centre.
So come on you guys - catch up!

Sourced to meet the world’s best specifications

With business going from strength to strength,
KINCROME recently relocated to a new purpose
built administration and distribution facility
designed to suit growing operations.
Prior to the move, KINCROME had used a
variety of cabling solutions and were a little
unhappy with their existing RJ45 patch panel
setup. As a result, KINCROME met with
communications specialist and KRONE endorsed
installer, Beyond Communications P/L, to discuss
various options for a new structured cabling
system.
“On our initial contact with KINCROME, it was
specified that the main communications room
was to be a showpiece, and they therefore not
only required a high performance solution that
met their IT needs, but one that would be
ultimately neat and tidy,” said Michael Francis,
Sales Manager for Beyond Communications P/L.
With this in mind, along with the added
installation of a new IP Office VoIP phone system,
it was decided that a HighBand
®
25 Category 6
Patch By Exception (PBE) system would be the
best solution.
In newly installed PBE solutions there are no
patch cords or jumper cables visible to the front.
The system is totally hard wired from network
equipment to work area, providing a secure,

reliable, high performance infrastructure from
switch to work area, or PABX to telephone.
Resulting in a neat, uncluttered, aesthetically
pleasing system, that’s a breeze to operate and
maintain.
“We looked at both patch panel and PBE
solutions, and decided that PBE would be the
most suitable for the project,” said Mr Francis.
Beyond Communications designed and
deployed the new system for KINCROME. This
included the installation of PBE frames and
cabinets in the communications room, along with
fibre and patch panels for the warehouse. As well
as a full IP Office VoIP deployment, security and
CCTV system, access control doors, PA and a
projector lift and screen. Over 320 Category 6
data points were installed over a period of three
months.
“One of our only concerns with the installation
was ensuring the system tails were neat, as the
cabinets are located near the window, and in full
view of all who walk past. This was easily
overcome by utilising the MASTERMINDER cable
management product, which has worked
extremely well,” said Mr Francis.
The MASTERMINDER attaches directly onto
standard 19” racks, cutting down installation

T
he data centre is a key resource. Many
organisations simply shut down when
employees and customers are unable to access
the servers, storage systems, and networking
devices that reside there. Literally, millions of
dollars can be lost in a single hour of down time
for some businesses, such as large banks, airlines,
package shippers, and online brokerages. Given
these consequences, reliability is a key data centre
attribute.
Designing and building a data centre to meet
these requirements is not a simple or insignificant
task and ADC KRONE has a White Paper intended

to make this task more manageable. Topics
covered include the following:
■
Space and Layout
■
Power
■
Cooling
■
Cable management
■
Special issues with fibre
SPACE AND LAYOUT
Data centre real estate is precious, so designers
need to ensure that there is a sufficient amount of
it and that it is wisely used. A well-designed data
centre has functional areas laid out in a way to
ensure that:
Space can be reallocated easily to respond to
changing requirements, particularly growth
Cable can be easily managed so that cable runs
do not exceed recommended distances and
changes are not unnecessarily difficult.
The location of equipment cabinets and racks
should be arranged in a “hot aisle/cold aisle”
configuration to effectively dissipate heat from
electronics.
POWER
A power interruption of even a fraction of a
second is enough to cause a server failure. To

meet demanding availability requirements, data
centres often go to great lengths to ensure a
reliable power supply. Common practices include:
■
Two or more power feeds from the utility
company
■
Uninterrupted power supplies (UPS)
■
Multiple circuits to computing and
communications systems and to cooling
equipment
■
On-site generators
There is a method of classifying data centres
into four Tiers, with Tier I providing the least
reliability and Tier IV the most. Use this system,
which is described briefly in Figure 1, to help you
sort through the tradeoffs.

COOLING
Servers, storage area devices, and
communications equipment are getting smaller
and more powerful. The tendency is to use this
reduced footprint to cram more gear into a
smaller space, thus concentrating an incredible
amount of heat. Dealing with this heat is a
significant challenge. Adequate cooling
equipment, though a start, is only part of the
solution. Air flow is also critically important.
To encourage air flow, the industry has
adopted a practice known as “hot aisle/cold
aisle.” In a hot aisle/cold aisle configuration,
equipment racks are arranged in alternating rows
of hot and cold aisles. In the cold aisle, equipment
racks are arranged face to face. In the hot aisle,
they are back to back. Perforated tiles in the
raised floor of the cold aisles allow cold air to be
drawn into the face of the equipment. The

following diagram illustrates how this works.
CABLE MANAGEMENT
The key to cable management in the optimised
data centre is understanding that the cabling
system is permanent and generic. It’s like the
electrical system, a highly reliable and flexible
utility that you can plug any new applications
into. When it’s designed with this vision in mind,
additions and changes aren’t difficult or
disruptive.
Cable management begins with racks and
cabinets, which should provide ample vertical and
horizontal cable management. Proper
management not only keeps cabling organised, it
also helps keep equipment cool by removing
obstacles to air movement. These cable
management features should protect the cable,
ensure that bend radius limits are not exceeded,
and manage cable slack efficiently.
A key to optimised cable routing is ample
overhead and under floor cable pathways. Use
the under floor pathways for permanent cabling
and the overhead for temporary cabling. Separate
fibre from UTP cables
to ensure that the
weight of other
cables doesn’t crush
the more fragile fibre.

A
s in previous years, many industry colleagues
joined us to hear the latest developments
from ADC KRONE and to network on a business
and social level with other industry members.
The event program was designed to keep
network providers abreast of the major market
initiatives shaping network infrastructure
requirements. These include Deep Fibre for delivery
of broadband services, wireless network capacity
and coverage, and IP-based services delivery.
We were proud to introduce the new look for
the combined ADC KRONE entity and to share
how ADC KRONE’s solutions address the

challenges of network transformation.
Doug Ellens, Principal Senior Systems Engineer,
ADC USA, visited to introduce ADC KRONE’s
OmniReach
™
solution. OmniReach is a flexible,
connectorised, scalable Passive Optical Network
(PON). The latest FTTX technology in the last mile
for Triple Play Services, OmniReach facilitates the
steadily increasing demand in Australia for
bandwidth.
Michael Gallaty, Senior Projects System
Engineer, introduced SG-1, ADC KRONE’s Service
Creation Gateway, which allows real-time
management of internet sessions. SG-1 provides
extra capacity on demand and the ability to bill for
those sessions. Michael also presented the
benefits of ADC KRONE’s Megabit Modems,
which enhance your network by allowing greater
utilisation of existing copper infrastructure.
LoopStar
™
, ADC KRONE’s carrier class Wi-Fi
solution was presented by Alan Crawford, who is
the Indo Pacific Product Manager for Carrier
Connectivity, Wireless and Wireline products. The
LoopStar Wi-Fi family features an industry-first,
line-powered access point that offers service
providers a low cost and easy-to-deploy approach
for building a network of Wi-Fi hotspots. With

this Wi-Fi solution, service providers can fully

THE FUTURE
leverage the value of their
copper infrastructure and
network assets to extend
broadband wireline into
the wireless network.
Tim Takala gave us a
glimpse of the future of
Power over Ethernet (PoE)
and its impact on migration
of services to an IP environment. Initially developed for VoIP, the
benefits of this enabling technology extend beyond IP telephony.
Many applications that deploy equipment with low power
requirements in areas that are not already wired for power will benefit
from reduced cabling costs. A single standard Ethernet cable will now
be able to provide both power and communication services to a

wireless network.
After the in-depth sessions of the day, Happy Hour was well
received! Our guests
then had the oppor-
tunity to learn more in
a one-on-one discus-
sion with product
experts and presenters.
The evening concluded
with dinner, accompanied
by some great enter-
tainment from Shane
Bourne.
