INTRODUCTION

Why structured cabling?

• Major risks connected with non-standard cabling:

– Network performance is lower than the one specified by the standards

– High cost of making changes to the system(the so-called MAC – Moves, Adds, Changes procedures)

– Inability to support new technologies


• As the principles of structured cabling design and installation become increasingly recognized, the installed network equipment becomes less and less expensive and the efficiency of data transmission grows exponentially.

• The structured cabling system has been the basis for information network as long as it exists. It is a foundation, which enables all business applications.

• A well designed, assembled, and maintained cabling system reduces maintenance costs at all stages of its lifetime.


Lifetime of different components of a building’s information infrastructure(sources: ANSI/EIA/TIA-568, HP, Siemon)

Software – 1.5 years

Work stations – 2.5 years

Networking equipment – 3.5 years

Minicomputers & mainframes – 5.5 years

Cabling system – 10-20 years

Building frame – 40+ years


Reasons for information systems downtime(sources: Sun Microsystems/Gartner)

Environment – 14%

Human errors –15%

Infrastructure – 71%:

Equipment – 25%

Software – 25%

Cabling system – 21%

• According to statistics, imperfect networks are responsible for up to 70% of all information system downtime.

up to $50,000/h – 5%

n/a – 23%

$26,000/h – 26%

$1,000/h – 42%

• Nortel Networks:

– Numerous research results show the actual price of

downtime.

Thus, for example, “In the energy supply industry the loss of

one hour can cost you millions of dollars.”

– All studies show that if a major company stops its activities for

one or two days it will probably stop being an independent

business.


Not critical – 6%

Over 24 hours – 1%

8 to 24 hours – 12%

3 to 8 hours – 24%

1 to 3 hours – 30%

Up to 1 hour – 5%

Downtime impermissible – 22%

Tolerable information system downtime – results of IT managers’ estimations study (source: FRIEDHELM LOH GROUP)

Building infrastructure


• Information Week Research’s Outlook 2005:

– Typical company with annual revenue of 1.5 billion US dollars invested about 8% of its revenues into IT infrastructure and services in 2005.

– Although the cabling system usually exists longer than most other elements of the information infrastructure, its initial value is normally no more than 5% of total investments into the information system.Therefore, the structured cabling system is quite a valuable contribution to the efficiency of any institution or company.


Structure of investments to create the information system

Cabling system – 5%

Network equipment – 7%

Work stations – 34%

Software – 54%


• The latest statistical research has shown that about 40–50% of all company’s employees move around within the building each year.

What is structured cabling?

• ISO/IEC 11801 definition of structured cabling:

– “Generic cabling – a structured telecommunications cabling

system, capable of supporting a wide range of applications.

Generic cabling can be installed without prior knowledge of the

required applications. Application specific hardware is not a

part of generic cabling.”

What is Structured Cabling?

• Structured Cabling

– is not a telephone network

– is not a data network

– is not a cable TV network

– is not a video surveillance network

– is not a BMS, FLS, etc. network

• Structured Cabling –integrated building engineering infrastructure(upon which all listed above networks can be built).

Signamax™ Cabling System

• Signamax Cabling System – complete solution.

• Signamax Cabling System is built based on the structured cabling system.

• Signamax Cabling System is based on the rules and specifications outlined in ISO/IEC and ANSI/TIA standards.

• Signamax Cabling System Manual is an independent document.

Signamax Cabling System

• Signamax Cabling System Design Principles & Installation Practices Manual describes all aspects relating to

design,

installation,

administration,

certification testing,

registration

to apply for one of the Signamax warranties provided bythe Signamax Connectivity Systems.


• The Manual contains two groups of rules the compliance with which effects warranty issue –

– Requirements

and

– Conditions


• “Requirements” concern the rules relating to transmission performance, design and installation rules, certification testing, and applying for SCS warranty, i.e. those rules that are necessary to comply with to provide a high quality, reliable product such as Signamax Cabling System tothe end user.

• Failure or violation of one of the requirements, which are part of the Signamax Cabling System, can be the grounds for denial to provide the Signamax Cabling System warranty or, if the violation is discovered after the warranty has been issued, for termination of the warranty service and agreement.


1 All the rules marked by in the Manual are regulatory

(requirements) and are binding in case Signamax

warranty for the cabling system installed shall be

obtained.

The requirements are described by terms “shall,”

“must,” “prohibited,” “not allowed,” etc.


• “Conditions” concern the rules relating to common universal methods of design and installation, selection of materials or equipment, supply of certain cabling system resources needed to ensure its long-term continuous operation andthe possibility of improvement over the whole warranty period as well as adaptation to new telecom applications and technologies.

• Conditions are the requirements the effect of which can be limited by some unavoidable objective circumstances. In all cases when the condition can be implemented, it takes on the requirement status.


1All the rules marked by in this manual are advisory

(conditions) and must be complied with to obtain

the Signamax warranty for the cabling system installed

in all cases except for when they cannot be executed

due to objective reasons.

The conditions are described by the terms

“recommended,” “allowed,” “permitted,” etc.
