KRONE, globally, celebrated its 75th anniversary recently Seventy-five years, in any industry is quite an achievement 75 years in telecom-munications is monumental The industry has experienced a lot of change since Gustav Krone established the company KRONE & CO in Berlin in 1928 The editorial on page 4 provides an interesting insight into some of KRONE’s developments and achievements during its long history

If there is one thing that comes through loud and clear from this article, it

is the importance of the KRONE Group’s developments to the IT industry KRONE’s patented LSA-PLUS IDC connection technology switches more than ten billion contacts in telecommunication networks all over the world!

KRONE Australia, since incorporation in 1980, has become one of the most valuable subsidiaries in the Group The Australian designed and developed insulation displacement contact (IDC) technology, used in the QuickConnect General Purpose Outlet (GPO) and Ceiling Power Outlet (CPO), was awarded recently at the Institution of Engineers, Australia awards ceremony, where KRONE Australia received recognition for Contribution to the Construction Sector

Peter Davis, our Sales & Marketing Manager takes a last look at the pros and cons of using patch panel and module cross-connects This will

be Peter’s last article as he has chosen to retire from the company after more than 14 years of

loyal service I wish Peter well for his new career outside of the Industry

At KRONE Australia, we are committed to training and innovation The visit, in July, by Dr Brendan Nelson, Federal Minister for Education, Science & Training highlights our continued commitment to the development of the IT&T industry

In this issue we look at how KRONE products are being used to train high school students for employment in the voice and data cabling industry, as part of the VCAL telecommunications cabling project For more details see the article on page 12

Our annual AccessNET highTIME conference was held in Melbourne recently and provided us with the floor to update the market on the developments of the KRONE BROADBAND range This year’s event was a success with over

60 delegates attending

Also in this issue, we look at how the international Hertz organisation is benefiting from our HIGHBAND technology

We look forward to the challenges the remainder of 2003 will bring us

The RJ45 patch panel has been the favoured

system administration type for many years

-especially with systems managers with a strong

background in IT Systems managers with a

background in telephony systems, on the other

hand, have always tended towards the cabled

cross-connect solution

The question is, which is the best solution?

This is a tough question with no definitive

answer

I would suggest that there are six elements

that should be considered when faced with this

decision: installation size, topology, churn rate,

technical support, administration and cost Lets

look at each one in turn

INSTALLATION SIZE

A thumb guide is to use an RJ 45 patch panel in

a 19” rack in frames, for up to 150 users,

working on two outlets per user This means we

have to administer three hundred 4-pair cables

in the “ horizontal”

Sufficient patch cord management is critical

for ongoing administration and to ensure a neat

and tidy frame Experience has shown that when

the 300 horizontal cable number is exceeded the

patch panel system is seriously challenged in

terms of administration The cabinets become a

virtual birds nest of patch cords that make little

sense to anyone in the organisation

For cross-connects that require more than 300

cables, serious consideration should be given to

a high-density cross-connect system These

systems provide better patch cord management

than is found with 19” rack mounted patch

panels

TOPOLOGY

Topology plays a major role in determining the

size of the cross-connect In installations that

have a centralised communications room,

high-density cross-connect systems are very close to

being a mandatory requirement This is due to

the amount of horizontal cabling that needs to

be connected to the myriad of available services

An important issue here is that the installation

needs to be managed over a long period of time,

so the administration of the cross-connect is very

important Cross-connectsutilising disconnection

modules allow for better/larger labelling than can be applied to RJ 45 patch panels

CHURN RATE

This is the number of times services are changed

Many organisations have a high churn rate, that

is, people and services are constantly moving around the building When people move, IT services must follow creating a re-patch requirement at the cross-connect

Patch panel cross-connects lend themselves to easy changes For this reason they are often the cross-connect of choice, but there is an inherent problem with this Because it is relatively easy to carry out changes, unauthorised changes can (and often do) occur Not only does this raise concerns with security, it also renders the records useless (we are keeping records aren’t we?)

Organisations with a low churn rate do not have such a reliance on the

cross-connect and can do well without the investment

in patch panels and the expensive 19” racksto put them in

With the move to Voice over Internet Protocol (VoIP) the churn rate is becoming a mute consideration anyway

VoIP telephony systems and Virtual Networks are allowing the IT manager to provide access to all services everywhere in the building, possibly removing the need for a cross-connect altogether!

TECHNICAL SUPPORT

Nearly all business systems are IT dependent The IT infrastructure is often described as “ mission critical” to the ongoing success of the business

The IT manager has a full-time job ensuring minimum down time The last thing they want is

a structured cabling system, in particular a cross-connect, that demands time from their already busy schedule

Telecommunication equipment was just beginning when Gustav Krone established the company KRONE & CO in a backyard in Berlin in 1928

The first major customers of the company were Deutsche Reichspost and Deutsche Reichsbahn, which bought the new cable connection device developed by KRONE

During the following years, KRONE developed and manufactured distribution and protection equipment for power supply applications As early as the 1940s, KRONE developed a modern telephone with its W 38

After World War II, Gustav Krone and his eldest son Heinz established the company Fa-Me-Ku (factory for metal and plastic) KRONEKG was founded three years later - setting the stage for the continuation of KRONE’s global success

KRONEhasalwaysbeen characterised

by a dedicated innovative spirit Today, KRONE technology is the standard in the field of telecommunications in more than 140 countries

The end of the 1960s marked an important breakthrough for KRONE

The LSA-PLUS® quick connection system was developed The LSA-PLUS

technology was patented in 1978 and today LSA-PLUS switches some ten billion contacts in telecommunication networks all over the world

In the 1970s and 1980s, KRONE expanded its product range adding power and information systems Since the end of the 1980s, KRONE has been manufacturing fibre-optic systems for broadband communication networks

KRONE established its first subsidiary in 1973

in Austria Five years later KRONE UK was established Between 1974 and 1989, KRONE subsidiaries were set up in Australia, Chile, South Africa, the US, Hong Kong, Spain, Italy, New Zealand, India, Brazil and Turkey

Klaus Krone became CEO in 1984, setting a committed internationalisation course for the company At the beginning of the 1990s, KRONE added copper and fibre-optic solutions for in-house networks to its portfolio

During the course of its history KRONE has steadily developed from a producer of components to become a system manufacturer KRONE established its position as one of the leading suppliers of products and network

Globally KRONE has reached an import ant milest one - 75 years Not many companies can boast a hist ory as long as t hat

technology solutions in the global

telecommunications market

KRONE connectivity is the basis for

future-orientated public networks and

high-performance premises networks alike More

than half of the products marketed by KRONE

are new, unrivalled products, that did not exist

on the market before

KRONE LINKS THE WORLD

The KRONE Group is today the world’s leading

manufacturer and supplier of components and

system solutions for telecommunications and

data networks As a global player, KRONE boasts

30 subsidiaries

KRONE’s products comply with all applicable

standards and KRONE’s quality management has

been accredited according to ISO 9001 The

KRONEgroup has over 3,000 patents worldwide

KRONE AUSTRALIA GOES FROM

STRENGTH TO STRENGTH

Since incorporation in 1980, KRONE Australia

has become one of the most valuable

subsidiaries in the KRONE Group

Shortly after establishing full manufacturing

facilities at Berkeley Vale, on the Central Coast of

New South Wales, the subsidiary established a

R&D facility in 1985 Today, KRONE Australia has

invested over A$75M in this facility

During the 1990’s, KRONE Australia was

responsible for the development of the majority

of the most successful copper connectivity

products to be released by the Group These

products include the lead-frame Cat5 RJ45 range; and the HIGHBAND® range, including Ultim8™, which

is still the world’s most efficient high-speed data cross-connect solution KRONE Australia has also led the KRONE Group in the field of Industrial Wiring Products with the TERMINATOR® range and new IDC power outlets

KRONE Australia is the Regional headquarters and Manufacturing Centre of Competence for the Indo Pacific Region

KRONE TOM ORROW - THE WAY HAS BEEN PAVED

In the world of local, regional and global telecommunication networks, the trends for the coming years are clearly signposted: Interactive, multi-media applications will become more and more popular, and soon be part and parcel of private and business life This means that the demands on the performance and reliability of networks will increase further

The solutions offered by the KRONE Group today already meet with future requirements

Not only do they offer high transmission capacities, but thanks to their modular design in particular, they offer a high degree of flexibility which is needed for the new multi-media services ∀

The introduction, in July 2003, of an Industry Code of Practice on “ Cabling Requirements for Business” (the Code of Practice) places obligations on entities that contract, or are otherwise engaged in, cabling activities but are not covered by the CPRs These obligations are

in addition to the responsibilities placed

on individual registered or licensed cablers by the CPRs

Previously, businesses had no mandated role in the application of the CPRs As a result, the impact of the compliance effort was reduced

The Code of Practice requires that businesses engaging in cabling activity ensure that cablers, working on their behalf, perform work in accordance with the CPRs

WHAT THE CODE WILL ACCOM PLISH

The Code of Practice ensures that:

∀ Businesses as well as individuals engaging in cabling activity will meet

a set of minimum standards

∀ Compliance arrangements will be regularly monitored and reviewed

∀ Consumer complaints with regards

to cabling by Code signatories will

be resolved in a timely manner

∀ Compliance with cabling requirements will improve over time

∀ Regulatory compliance will be spread across a greater proportion of the industry

∀ Businesses as well as individuals will

be responsible for maintaining a high standard of cabling related work

HOW THE OBJECTIVES WILL BE ACHIEVED

Now that the Code of Practice has been registered by the ACA, businesses that wish to

be Code signatories will be able to chose between two tiers of compliance

Tier 1 - Code Signatory to the (Code Rules)

The business elects to sign up to only the mandatory provisions of the Code of Practice under Part 4 of the Code They will continue to

be subject to inspection programs and compliance assessment

Tier 2 - Code Signatory to the (Guidelines)

The business elects to sign up to the mandatory provisions of the Code of Practice under Part 4 of the Code, as well as committing

to comply with the voluntary provisions under Part 5 of the Code They can choose from a range of options in order to meet a minimum

100 point score

Businesses who have signed up to this option will be subject to the inspection program, but exempted from additional compliance assessment

BENEFITS TO CONSUM ERS

Through peer pressure and public visibility, both mandatory and voluntary levels of cabling installation performance are encouraged to improve The Code of Practice will contribute to the maintenance of ‘uniform satisfactory levels

of installation skill’ in the industry

The Code of Practice will also introduce a system of handling consumer complaints in line with the mandatory compliance elements of the Code of Practice

BENEFITS TO INDUSTRY

The Code of Practice will publicly recognise those businesses committed to ensuring quality installation and maintenance practices are adhered to It will also provide greater certainty about the minimum standards for service delivery in installation and maintenance of telecommunications cabling

To learn more about the Code of Practice, visit www.aca.gov.au/telcomm/industry_codes/regist er_of_codes/codint.htm or contact the KRONE

To coincide with the launch of the Federal Government’s New Apprenticeship campaign, Dr Brendan Nelson, Federal Minister for Education, Science & Training visited KRONE’s Berkeley Vale facility recently to meet with the apprentices currently employed by KRONE Australia KRONE has eleven apprentices employed at present in a number of areas Dr Nelson was very interested in finding out how the apprentices had undertaken their training; he was impressed with the success KRONE is having with our apprentices

Traditionally, apprenticeships took three to four years to complete and traineeships lasted for one to two years New Apprenticeships are ‘competency based’, this means that it may be possible for a New Apprentice to complete their training sooner if they have reached the skill level required

It is even possible to start a New Apprenticeship while still at school

Dr Nelson’s visit gave KRONE the opportunity to showcase our world-class manufacturing capabilities, our state-of-the-art fibre manufacturing cell and also our commitment to this

If you are a current KRONE Master Installer with a current

License/Registration, there is no need to do anything about

Transitional Registration - the following is for your

information only

If you employ people with Transitional Registration in the

security, fire and data industries, then the following applies

to you

Transitional Registration was introduced as an interim

measure to phase in cabling regulation in the security, fire

and data industries Previously cablers in these industries

were exempt from licensing or registration requirements

Under the Cabling Provider Rules of October 2002 (CPR),

transitional registration allowed cablers in these industries

to work behind a compliant device, for example an alarm

panel or modem, but not between the compliant device and

the network boundary, for example a socket, network

boundary device or distributor

Transit ional Regist rat ion ends on 2 Oct ober 2003

After this date you MUST have completed an Open

Registration course and you MUST be registered with one of

the five Registrar

You cannot use your transitional registration after 2

October 2003 If you do, you will be working illegally and

will be carrying out unauthorised cabling work This is a

breach of Section 420 of the Act and you could face a fine

of up to $13,200

Also, working without the relevant competencies

increases the risk of sub-standard, or unsafe work

The ACA has the power to prosecute you for

non-compliance with the Telecommunications Act 1997 or

contravention of the CPRs Failure to comply with either

regulation is a criminal offence and is punishable on

conviction by a fine of up to $13,200

As a KRONE Endorsed Installer, it is a condition of your

Installer Agreement that all of your installation staff have

the minimum qualification of Open Registration and that at

least 50% of the staff on a KRONE site have a KRONE

Master Installer Certificate of Competency KRONE

encourages all cablers to have their Open Registration Card

There’s a lot of networking going on too

With Hertz nothing but the best will do That applies equally to its customers, its staff and its operations, declares its European MIS Director, Paul Bermingham, whose base is the new extended European service centre at Swords, close to Dublin airport and ten miles from the city centre He states, “ Our mission statement for the centre is to provide a service that exceeds our customers’ expectations, while our vision statement demands that we be models of service excellence within the Hertz Corporation, amongst our global competitors and the Irish business community “

Having the right tools to do the job helps of course, which is why Hertz has just extended the customer service centre and equipped it with the latest ICT infrastructure To mitigate the effect of equipment failure the networking hardware is fully duplicated, whilst generous spare capacity has been built into the cabling system to minimise dislocation when moves and changes inevitably occur

PRUDENT M OVE

Iain Cosgrove, MIS Manager at the Hertz European Service Centre explains, “ Because we service our entire European reservations operation and many of the financial back office functions from this single location we cannot allow even the slightest glitch to occur

Everything from customer reservations to customer accounting, customer relationship management and other operations that support

a business are carried out from here, by telephone, post, e-mail and fax In all we look after eight countries-Switzerland, Germany, France, Italy, Belgium, the Netherlands, Spain and of course the UK Whenever a customer calls from any of these countries,

it’s here that their enquiry is dealt with When you consider how our entire operation relies on this one location, making the support system uninterruptible is highly prudent.”

The service centre is moving towards a paperless environment Currently a number of key documents are scanned to disk for subsequent on-screen recall and reference Telephone calls account understandably for much of the centre’s work and calls are routed here from Hertz customers in each European country All inbound voice calls for both reservations and customer relations are handled

by dual Rockwell Spectrum automatic call distributors (ACDs), whilst an Ericsson MD110 switch handles the administrative functions Cisco infrastructure handles the data side of things with two 6509 core switches and 13 4004 workgroup switches, with 100BASE-T to the desktop

KRONE HIGHBAND®

The new network that supports all this is with little doubt one of the largest installations in Ireland As befits a state-of-the-art facility, it is to the ratified Category 6 standards and uses the KRONE PremisNET™ solution throughout, installed between January and December of last year Stage 1 took cables branching from the two comms rooms to KRONE HIGHBAND IDC Connection modules in underfloor consolidation points, whilst the second stage, phased with the other works of finishing the new building, extended the network to three RJ45 connection points on each desk - some 4,000 outlets in total Says Iain, “ Everything has been designed for maximum flexibility and ease of use So we stipulated separate voice and data ports at each workstation, with two spare sets for every four desks For every eight to 12 desks a separate concentration point with comms, data and mains power outlets is provided and this built-in flexibility means that any individual workspace can be replanned and consolidated without the need for major recabling.”

Resilience is the other fundamental design feature of the network, with all major elements duplicated The cabling system originates from different comms rooms and is designed in such a

way that should one of the comms rooms fail for

any reason the effect on business would be

minimal A complex voice and data backbone

cabling system has also been incorporated to

complement built-in reliance features in the

active equipment He relates how he has

powered down one of the two 6509 switches

and seen the whole network reconverge within

one ‘ping’, without any user noticing There are

numerous file servers, two ACDs and four

comms rooms The entire network has been

configured so that any critical device could fail

without disrupting operations and the link to the

outside world is duplicated with ISDN backup

ATTRACTIVE LOCATION

‘Home from home’ is an entirely appropriate way

of describing the service centre, for not one but

two reasons To begin, it’s an attractive location;

set in parkland, the brand-new extension is

bright and airy, with many picture windows

Staff have the advantage of a superb restaurant

plus a gymnasium to lose those pounds

afterwards There is also a cybercafé where

people can surf the ‘Net and transact their

e-mails off-duty (for security this facility uses

entirely separate network connections)

State-of-the-art workstations make working

hours more agreeable too The modular

furniture has an aesthetic design, with

ergonomic aspects that can be assessed by an

on-site occupational health nurse

“ Our staff are one of our greatest assets,”

declares Paul, “ so the facilities are an

investment, not an overhead Thirty different

nationalities are represented among our 1,200

people on site, working in office areas that

correspond to the different countries served by

Hertz We see this cultural diversity as an asset

and it’s reflected not just by the flags and

mementos in each section but by our core values

that are an integral part of our working

environment on a daily basis.”

TALL ORDER

In charge of installing the structured voice and

data cabling installation was the Dublin-based

firm CISCom Technology Ltd Although no

problemsoccurred during the installation process,

it was nonetheless quite a tall order, according to

CISCom managing director, John Bentham

There were, he explained, strict handover

dates to be observed at each phase of the

building operation Working in a

multi-contractual environment meant the installation team had to be vigilant to ensure the installed Category 6 cables were always protected;

replacing damaged cables after a phase was completed was not an option

CISCom designed and customised the concentrator floor-boxes using KRONE HIGHBAND modules, then had them approved

by the Hertz IT team The size of the workplace, coupled with the resilience stipulated by the client, meant the cable installation and administration methods were quite complex

Installing 4,000 cables in phase 1 and another 4,000 cables in phase 2 also meant they had to produce and maintain accurate drawings and records These documents were critical to the Hertz IT team, who performed all final device connectivity in a very short timeframe

He continues, “ Unquestionable quality of materials and workmanship were stipulated and

I think it was our choice of KRONE components that secured the Hertz contract for us We use KRONE product exclusively because of its very high specification, years of good experience and the excellent technical and sales support we get from KRONE and our local distributor, Wood Communications.”

NUM BER ONE

Paul Bermingham concludes, “ The extended European service centre is a great source of pride

to Hertz, to our people and I think, to the Systems Integrators who put it all together for us

Hertz is number one in car rental and the service providers we choose are also number one.” ∀

“ We use KRONE product exclusively because of

Following a brief introduction by KRONE’s Managing Director Craig Jones, which outlined our achievements and our investment in Australian manufacturing and R & D on the company’s 75th anniversary, Peter Meijer, KRONE’s Technical Training Manager took the opportunity to outline the relevance of the Cat 5 and Cat 6 structured cabling standards in the modern carrier’s network

With the appearance of Ethernet in the last mile, the importance of signal to noise ratio is greater than ever and Peter spoke in detail to the enthusiastic audience on this subject

With this still fresh in the customer’s minds, Alan Crawford, Product Manager Fibre Optics updated the delegates on the latest developments in fibre cable technology, including information the fibre line opened recently at the KRONE manufacturing facility at Berkeley Vale, NSW

Alan also spoke of the benefits of Free Space Optics in terms of rapid response and flexibility

of installation and outlined the entire KRONE Fibre product range before giving a live demonstration of Free Space Optics

I kicked off the afternoon session with a presentation on the methodology of providing protection from Overvoltage and Overcurrent surges on telephone and power lines and a video clip of a live demonstration of the real effects of powerline faults and lightning strikes on communications equipment

The buzzword of the moment is Broadband, and KRONE’s Regional Business Development Manager for Indo Pac region, Dave Anderson gave the delegates an insight into the development work KRONE has undertaken in Australia to prepare the industry for this next phase

With the appetite for Bandwidth growing at

an alarming rate, KRONE has applied the benefits of our world leading HIGHBAND®

solution to the next generation of Carrier’s termination devices under the name of KRONE BROADBAND
