O
ur HighTIME conference held
earlier this year revealed that
efficient data throughput is the
chief consideration of network
managers - not network speed.
Presentation after presentation,
indicated that network managers
were spending far too much of
their valuable time on finding
network faults.
According to research from
Gartner Group, 39 per cent of a
network manager’s time is spent on
managing faults created by
slowtime - even though he or she
has more important things to do. Network
managers should be concentrating on planning
for future network upgrades, keeping abreast of
new technologies and managing the IT team.

KRONE is expanding its optical fibre capability
as the Australian distributor for Optical Access -
a leading manufacturer of next-generation
optical wireless solutions. This article is featured
on page 9.
We’re delighted to be able to report that Air
Services Australia (ASA), a Government-owned
commercial authority responsible for the
management of air traffic control over 11 per
cent of the world’s surface, has chosen our
Premis
NET
TrueNet Platinum solution as its IT
infrastructure to take it through the next stage of
its development. For all the reasons I mentioned
above, ASA opted for TrueNet and its guarantee
of zero bit error data throughput.
From the premises network to the access
network - when one of the largest wholly owned
Internet Protocol networks on earth, WorldCom,
wanted to establish an Australian entity, it was
vital the carrier’s cabling infrastructure was able
to support every data service under the sun.
Communications infrastructure project mana-
gement specialist, MK International tells us why
it chose KRONE for WorldCom’s Australian
network.
We are committed to keeping you, our
partners, up to date with industry standards, our
products offerings and changes within our

organisation.
If you have any questions you need answered,
or topics you’d like covered, let us know. Call
your local KRONE representative or e-mail us at:
We rely on your
support and we’re here to help you.
Sincerely ...

rom my many conversations with KRONE end
users about their companies’ dependence on
the information technology (IT) infrastructure, it
is clear that all of them have a near total
dependence on IT across all sectors of business -
whether they be small to large business
enterprises, educational institutions, financial,
health, commercial or government organisations.
Imagine if a call centre lost its IT capability, even
for a day!
Research suggests that organisations have
between 80 to 100 per cent dependence on their
IT infrastructure. Networks fail either from
downtime (total loss) or, as is more often the

case, ‘slow time’ loss.
In the case of downtime, a company’s loss can
be classed as nil productivity (idle staff still getting
paid) and revenue loss (earnings from lost sales).
The Standish Group (USA) estimates that total
LAN downtime can cost a company up to
US$13,000 per minute.
However, even though your network is up and
running, it can be draining you of revenue and
productivity. The green light on your computer’s
NIC card only means that you have established
an electrical connection. It does not
mean that you have sufficient
network throughput.
The Infonetics Group (USA)
estimates that of all productivity loss,
only 31 per cent is attributed to
downtime and a huge 69 per cent to
slowtime.
WHAT IS SLOWTIME?
Slowtime is when the network is
overloaded with data transmission to
such an extent that the whole
network’s throughput is slowed
down.
Broken or inferior cable, poor
connectors or patch cords,
mismatched components, impedance
problems, inadequate standards - all
of these are issues which impact on the

effectiveness and efficiency of your cabling
infrastructure and can therefore severely impact
on your business.
Zona Research (USA) determined that network
slowtime cost financial brokers US$33 million per
month and travel agencies US$28 million per
month. Poor load times for Web pages may have
resulted in as much as US$4 billion in lost e-
commerce sales, Zona estimated.
Almost 100% of businesses employ Ethernet
as their preferred data transmission medium.
One of the major designers of Ethernet, Robert
Metcalfe, said that when only one bit of
information is corrupted during transmission, the
entire packet of bits of information needs to be
retransmitted. This slows the network’s data
throughput down by 80%. Imagine spending a

ENSURING MAXIMUM RETURN ON
YOUR CABLING INVESTMENT
“The collection, dissemination and analysis of customer information has
become an essential prerequisite of a modern operation. Technology is no
longer just an aid to the strategy. It is the heart of the strategy.”
— Paul Anderson, ‘A Call from the 21st Century’
If you have invested a million dollars in your IT
infrastructure and you have one per cent
retransmissions in your network, you are losing

$200,000 because of poor cabling connectivity.
million dollars on IT investments, only to get
$200,000 worth of return because of poor
cabling connectivity. That’s not a technical
problem. That’s recipe for a business disaster!
As business evolves in this rapidly changing
world so, too, does an enterprise’s reliance on its
IT infrastructure. The network must evolve with
the strategic future of the business firmly in place.
Network designers face the challenge of
balancing a number of different factors before
specifying any system: current business IT needs,
potential expansion, future demand, emerging
technologies and industry standards.
Instead of getting bogged down with fault-
managing, IT managers should be spending their
time on planning and advising business managers
A good high performance solution should be
invisible to the IT management team and be
warrantied for its performance.
If organisations have such a high dependence
on their IT infrastructure, how are network
managers spending their time?
According to the Yankee Group, a network
manager spends his or her time on: planning - 9
per cent; advising - 12 per cent; upgrading - 12
per cent; managing - 12 per cent; net monitoring
- 16 per cent; and fault monitoring - a massive 39
per cent.
Speaking at our recent HighTIME 2001

seminar, Peter Fernie IT Director of market
research giant, AC Nielsen, reported on the
improvements he has experienced since his
company installed the KRONE TrueNet Silver
solution in January this year. He estimated it has,
so far, allowed him to free up two highly skilled
IT technicians from cable fault-finding duties to
undertake other work.
At another conference, I heard an IT end user
listed his data cabling requirements as:
"
the solution should be rated at least to
100Mbps (Note that he is talking in bits which
is a data term and not in Hertzs which is an
electrical term.);
"
there should be some guarantee of
performance;
"
there should be longevity;
"
it should be able to handle increasing loads
from emerging technologies and corporate
growth;

the solution should fit within his budget limitations; and
"
it should be a structured cabling solution able to be
patched efficiently for easy maintenance.
Clearly, he is interested in making sure the data he sends is
transmitted quickly and efficiently but he does not have a
fixation with the electrical parameters of copper cabling.
Yes, he expects it to comply to industry standards but his real
interest is efficient data throughput.
His requirements mirror the questions you should be
asking of your cabling vendor. While the physical layer or
cabling might only comprise 5 per cent of an enterprise’s IT
budget, it can account for 30 percent of a network’s

downtime. The structured cabling solution is the vital
foundation for ensuring the Chief Financial Officer or
Managing Director achieves a maximum return on his or her
IT investment.
If you have a network that carries mission-critical
information vital to your business active testing is the only
true measure of performance. KRONE’s TrueNet Solutions
incorporate active testing before a 5-year guarantee against
slow time is issued. For further information please contact
your nearest KRONE office.
KRONE’s range of fibre cable has been
expanded to include outdoor loose tube cables.
This cable is available in 4, 6, 8, 12 & 24 core
counts in both Singlemode and Multimode and
is LSOH with nylon jacketing as standard and
with sacrificial sheathing also available.

Airservices Australia is installing KRONE
Australia’s TrueNet Platinum level Cat 6eT end-to-

end cabling solution over seven floors of its
headquarters in the Alan Woods building in the
Canberra CBD.
A Government-owned commercial authority
responsible for the management of air traffic
control over 11 per cent of the world’s surface,
Airservices Australia’s growth and the explosion
of technology has lead the organisation to
refurbish its headquarters, floor by floor. The
$500,000 project which incorporates KRONE’s
TrueNet Cat6 cable and Australian-designed
HIGHBAND RJ45 data outlets, Patch Panels and
Modules, will be completed by the end of 2001.
Five years ago, when Airservices Australia was
formed as a service provider for the Australian
airways, very few people could have envisaged
the levels of demand placed upon a
communications network. A tidal wave of e-mail,
Internet, Intranet and multimedia applications
challenges this infrastructure every day.
Airservices Australia was keen to circumvent
any difficulties caused by its own growth and
emerging technologies which could endanger its
mission-critical network, either by slowtime or
downtime. Two key departments in the
organisation with extremely diverse needs were
sharing one computer room: Comserve is a
carrier, responsible for connectivity to the world;
and IT Services looks after the enterprise’s
computer network in the building and major

connections to every capital city in Australia and
remote sites along flight paths.
The refurbishment enabled two computer
rooms to be built on separate levels and the
PABX was also relocated to a more strategic
position. The new network also allows the IT
team to more efficiently and quickly handle the
moves, adds and changes that are part of the
daily routine in a large organisation. Built into the
network is a further 25 per cent capacity to
handle increases in bandwidth requirements.
Already a KRONE customer for its Cat 5
solution, Airservices Australia was impressed by
the guarantee that came with the TrueNet
solution - it actually promised zero bit error rates.
Patrick Fleming, communications specialist
responsible for overseeing the data installation at
Air Services Australia, said: “We selected KRONE
products because of the guarantee. There were
other competitive bids for the business, but that
was really the decider.
“KRONE has guaranteed Airservices Australia a
zero bit error rate on throughput for five years
and the cabling infrastructure has a 20-year
warranty for parts and labour.
“Testing is a vital part of KRONE’s service. It is
the key to the TrueNet solution. They have
developed a methodology which tests the system
while it is operating.
“We’re just about two thirds of the way

through the project and they have tested 10 per
cent of the installed cable to ensure it passes
their stringent guidelines designed to eliminate
data retransmission.
“As the refurbishment commences on each
floor, they conduct a test. Even to the extent
that, as gyprock is installed, they test that the
segmentation of cables within the walls is
correct, prior to the second sheet being erected.
“I understand, even at this early stage,
slowtime - or time lost by retransmission of
information - has been eliminated,” said Mr
Fleming.
Peter Davis, Sales and Marketing Manager,
KRONE Australia, said: “Our customers need to
Zero bit error guarantee means no
retransmissions for this mission-critical
communications network.
