Dear Customers and Partners,

The field of computer and telecom wiring has undergone major changes thisyear with the introduction of 3 new wiring categories:

Cat. 6 for class E links at 200 MHz

Cat. 7 for class F links at 600 MHz

optoelectronic at several GHz

These three new categories are calling into question not only connectors andcables, but also their setting up.

To meet these requirements, INFRA+ has created a new line of fully modularequipment capable of handling any of the three new categories, evensimultaneously.

This technological advance is an asset for all wiring market players who wantto enhance and promote their services.

This document summarizes conventional know-how and is extended bytraining courses which stress the latest technical changes.

We take this opportunity to thank the 1,600 trainees who placed theirconfidence in us in 1998.

We are also convinced that our industrial innovation would not have beensuch a commercial success had it not been for the competence of thecompanies who brought it onto the market.

Yours sincerely,

Alain Le PALLECHead of training

Alain Le PALLEC has worked for 20 years in the world of wiring. He has assumed important technical responsibi-lities (inspections, quality, Design Office). The considerable experience that he has acquired, his generous perso-nality and his taste for education have led him to dedicate himself to training.

The information in this guide is given only as an indication. Its use does not commit the responsibility of INFRA+.


After a period of stability that lasted for about 7 years (introduction of category5 at 100 MHz), under the pressure of the considerable increase in computertransmission capacities the wiring world has undergone an unprecedentedchange with the introduction of category 6 at 200 MHz and category 7 at 600MHz.

IBCS has been able to adapt to this new challenge and now offers 7 levels ofservices corresponding to all cost or performance requirements currently possible(see table, section 3.2).

Before we go into technical details, we would like to remind you that IBCS is anadvanced, open and cost-effective system which will add value to your buildingsby giving them "intelligent upgradability". Nevertheless, we draw decision makers'attention to the fact that in order to make the most of the system, it is essentialthat they:

examine certain issues that must be included in their specifications

seek the help of professionals in order to obtain an electronic building that bestmeets their needs, at the least cost (except if they have in-house engineeringskills, which is not often the case.).

Indeed, electronic systems have brought major changes to equipping buildingsin the service sector: computers, telecommunications, technical and administrativemanagement, security systems, automation, etc.

The architect who designs a service sector building must take into account theinstallation requirements of these systems as early as the first sketches, other-wise the building:

may be unsuitable for its intended use (there are buildings that cannot be soldor are impossible to rent at market prices because they are not adequatelyequipped)

may necessitate costly, additional "upgrading work", which is unthinkable in anew building

In this chapter, we will carry out a broad analysis of the wiring environment ofbuildings, leading to:

an overall, all-encompassing view of the technical equipment and networksconnected

thought on the organization of the building, and space ergonomics in servicesector work.

Furthermore, wiring has a significant impact on the building as structural equip-ment. The quality of the wiring will dictate the ease and cost-effectiveness of theconnection and organization of optional equipment such as: terminals (tele-phone, office equipment, video), active network systems or central systems(automatic telephone switchboards, alarms, etc.). This optional equipment istotally independent of the building.

1.1.

OWNER'S

REQUIREMENTS

1. ADVICE FOR SUCCESSFUL WIRING


It is no longer possible to ask a professional "make me a good computer system,a nice technical management or access control system ...". Intelligent enginee-ring is indispensable. Everything must be identified: connecting equipment,cables, workstation socket supports, identification method, as well as adapting,dividing or patching possibilities (by pairs or four pairs). A components parts listmust be drawn up with the list of suppliers, cost of equipment and its installa-tion cost. In addition and most importantly, transmission performance must beguaranteed by a contractually binding signal/noise ratio.

Tailored engineering (therefore correctly budgeted for!) is the precondition forimproved quality of buildings. It guarantees the functional distinction betweenstructural equipment and optional equipment. This is the key to the flexibility ofbuildings and their capacity to adapt to changing needs. This distinction willensure the maximum useful life of the buildings and reduce their operatingcosts.

The limitations described below are given only as an indication, since each buil-ding is a unique case. The method(s) used to run additional cables will dependon whether the building has a raised floor, trunking against the walls or a falseceiling.

NOTE: there is no ideal solution. The engineering and design office specializedin building wiring will always know which are the best compromises among thepossibilities offered by the INTEGRATION 45 range (chapter 8.1) and the poten-tial of the building. The architect must be involved in these choices.

Vertical runsThey consist of the risers located.The cable trays must be large enough to enable possible reconfigurations.

Horizontal runsThese are the most difficult to deal with as they require extensive building expe-rience. Chapter 8 is entirely devoted to this matter and presents all available orpossible solutions. The choice of horizontal runs and types of workstation supportsassociated with them has important impacts on wiring organization and flexibi-lity of space. This choice will have a definite influence on the working conditionsof the future users of the building.

Their location (whenever possible, at the center of the distribution zones), size,as well as climatic and electromagnetic environment must be thoroughly studiedby the engineering and design office. These rooms are certainly not designed forthe pleasure of the computer experts. They are essential, since they integrate alllow current equipment and sometimes high currents required in a communicatingbuilding.

1.2.

ARCHITECTURALCONSTRAINTS OF THE

BUILDING

Running the cables andsheaths

Service rooms


The divisibility of premises is the possibility of dividing it into several sections, eachbeing allocated to an independent user. In practical terms, this implies the possi-bility of allocating a service room to each divisible area, something which requiresa certain amount of care from the engineering and design office.

Flexibility is the possibility of adapting work spaces to all temporary or permanentlayouts requested by user companies. It will be indispensable that the worksta-tion sockets be movable within the workspace, easily reconfigured, sharable,etc. according to whether the organization consists of standalone workstations,workgroups dedicated to a specific task, multi-user workstations, etc.

The job characteristics given by the project owner are listed in chapter 7 in orderto define the wiring of the building. These characteristics must be included in thecall for tenders specifications. Let us remind you that the organizational qualityof a building is part and parcel of its future added value.

Every day brings more proof that a well-designed, therefore well-wired building,is easier to market or resell (especially on a competitive and depressed market),cheaper to operate and better suited to the needs of present and future users.

While these observations may seem self-evident, we often find that they areneglected. It is therefore essential that the owner, architect and prime contractorbe aware of the pitfalls to avoid:

poor definition of needs, incomplete programming

insufficient budget precision. Numerous budgets do not take engineering ordesign phases into account. Since a task that is not budgeted cannot befinanced, it will consequently always be set aside. Even a conscientious archi-tect or prime contractor cannot sub-contract the studies necessary to engi-neering and design firms if he does not have the funding to do so.

calls for tenders based on rudimentary or non-existent specifications (install aheating system, make me a nice computer system, etc.)

amalgamation of low investment jobs into a considerable financial weight. Forexample, the electricity job will include the weak current job which in turn willinclude the computer wiring job, access control system, supervision, etc. whilethese jobs require very different skills!

sub-contracting to a manufacturer (computer, telecomm or building technicalmanagement: the wiring will always be an element of prescription for hisequipment or services. Experience has shown that these "gifts" are usually paidfor at a top price.

sub-contracting to general contractors in the hope that they will manage to dealwith the inadequacies mentioned above

Divisibility and flexibility ofpremises

1.3.

RECOMMENDATIONS FORSUCCESSFUL WIRING


These inadequacies are frequently seen and give rise to faulty work and mediocreresults. Their cause is generally the lack of engineering. Serious studies are a veryproductive investment in relation to the initial cost of the building as well asoperating costs.

An excellent wiring system like the IBCS deserves to be studied and installed byhighly-skilled professionals. INFRA+ is at the disposal of prime contractors tosupply them with:

any technical assistance they may require a list of trustworthy partners (engineering and design firms, installers) visits to high-performance sites Samples from the INTEGRATION 45 range to simulate your workstations

The dimensioning of the installation is based on a quality and quantity inventoryof the requirements:

1 - Workstation characteristics:

Number of computer, telephone or general purpose sockets

Number of ordinary and backed-up 230V sockets

Types of distribution (walls, ceilings, floor) and flexibility required

Wiring organization: direct or via primary wiring layout in cable trays

Types of support (boxes, distribution columns, trunking systems, etc.)

2 - Number of workstations and distribution for each floor or zone distributionframe. Precise size of backbone cables and sub-distribution frames.

3 - Permissible communications frequencies 100/200 or 600 MHz but alsoand most important the minimum signal/noise ratio of the links (in dB) atthese frequencies

4 - Organization of networks and systems to be connected (if known and if thenetwork set-ups are proposed

5 - Life span required (5 to 15 years)

6 - Type of contractual guarantee

1.4

BASIC DATA NEEDED FORPREWIRING SPECIFICA-

TIONS


Engineering rules are now well known by professionals. Furthermore, they areincluded in standards EN 50173, EN 50174, NF C 15-100, as well as in thetechnical notes of the F3i* which includes comments on "state of the art" prac-tices and is the reference document for designers, installers and wiring users inFrance. In this document, we will mention only the basic rules and specificcharacteristics of the IBCS and its components. For more details concerning thestandards, please refer to chapter 6.

The wiring layout consists of horizontal star-configuration of RJ45 sockets using4-pair cables around floor sub-distribution frames (SD) which are interconnectedand connected to a general distribution frame (GD) through backbone cables. Asub-distribution frame can connect a maximum of 150 workstations (approx.300 RJ45 sockets) and can cover a maximum area of approximately 1,000 m2,which means a maximum density of one 2 RJ45 workstation per 6.66 m2.

Maximum length of links

The greater the transmission distance in the cable, the weaker and moredisturbed the electric signal going through it will be (degradation of thesignal/noise ratio). For this reason, the standard recommends maximumdistances. On a campus:

cumulated length of patch-cords: A + B + E ≤ 10 m(electrical equivalent)

length of patch-cords C and D ≤ 24 m

length F and G (of the equipment connecting cables) to GD and CD ≤ 3 m

With judicious engineering, the length of the links can be reduced and theirperformance considerably improved at little cost. (The average lengths observedare around 35 m).

Note: for large sites, INFRA+ offers new wiring layouts with centralized fiberoptic cables on the active equipment and floor telephone distribution withoutpatching (consult Engineering and Design firms).

Telephone equipment only, Cat. 5For this purpose the best choice consists of the 8-pair modules since they enablejumper connections.

For this purpose, the best connecting system consists of 19" RJ45 racks, sincethey enable the easy addition of active equipment on the rack. This takes up morespace (twice as much) and is more costly (3 times as expensive) as moduleconnectors.

The best connecting system is in this case made with 8-pair modules whichenable telephone jumpers as well as patch-cord patching. (In the Cat. 6 module,telephone patching can only be done through patch-cords).

Shared application socketsAs a result of the excellent crosstalk quality of MNC cables, the IBCS can beused to share links at the terminal sockets using a duplication adapter. The dupli-cation makes it possible to double the density of workstations connected. Regar-ding the applications of the small service industry where sockets on market stan-dards are recommended, this layout can be universally adopted because of thelow capacities used.

In this case, the connectors are associated by modules for the telephone andthe RJ45 connectors are rack mounted. You can either:

separate the RJ45 racks and the frames (recommended for large installations) or integrate the module supports in the same racks as the RJ45 panel s

(recommended for medium size installations). In this last case, duo MNCcables will always be the best option.

To connect any computer or telephone equipment, all you have to do is selectthe link diagram corresponding to the wiring code adopted (Section 2.4). Let ustake the example of the connection of a PC with its Ethernet card on a HUB 10base T on a link using the IBCS/FICOME/FT code.

Whether the links require 1, 2 or 4 pairs, the same method is used throughoutto match the terminals with their sources.

One of the major assets of the IBCS and probably one of the main reasons forits success is its ability to optimize wiring by sharing links. Doubling or quadru-pling the connecting capacity of a network simply by adding adapters is a func-tion that is well appreciated by building operators.

The symmetrical pair principle involves avoiding transformation of commonmode into differential mode. In other words, it simply avoids disturbance of thesignal transmitted. This phenomenon is not a problem: if the communication cardcannot read a frame, the software renews the operation. The inconvenience isthe time wasted which is often barely noticeable for the operator. This pheno-menon becomes a nuisance only if there is considerable transients interferenceon the local network.

The new 100 Mbit/s systems must not transmit at a high rate in order to complywith radiated transmission standards. Taking into account the cable attuenation,the signal cannot be much higher than 500 mV on the receiver end. There istherefore a risk of "lighting" the input circuit, for example if a mobile telephoneor a walkie-talkie in emission mode is placed nearby. In this case, the computercommunication will be interrupted during the HF emission.

The situation is different for common mode disturbances which penetrate theequipment and cause a blockage, which is by far the most frequent occurrence.By itself, a symmetrical pair cannot prevent common mode disturbances fromentering the equipment. Only filtering and shielding will provide an efficientbarrier.

When the unshielded system first came out, the communication cards were notfiltered and problems quickly emerged. Media filters soon appeared to try toeliminate these problems. Nowadays, suppliers of unshielded systems only vali-date an installation if the communication cards are filtered.

Most of the time, installers have no information on the equipment that will beconnected. Even if they had this information, they would have to ignore it tocomply with the commonality clause, a pre-condition for the durability of theinstallation. It is therefore essential to examine electromagnetic immunity in thepresence of unfiltered electronic terminals. For an unshielded installation, thewiring installer must ensure that successive users will be warned of the need touse filtered communication cards.

Filtering is sufficient against electrical interference but inefficient against themagnetic field of lightning or against static electricity that is strong enough todamage communication cards. Only shielding or screening provides an adequatesolution to all the immunity problems encountered on sites.

This is not a new phenomenon, having existed since the origin of weak currents.

It has now become a major concern because of the increasing sensitivity ofcomponents, the advent of digital electronics and the spread of networks.

Definition:

ELECTROMAGNETIC DISTURBANCES:Physical phenomena of electromagnetic origin which can cause equipmentor system malfunctions

ELECTROMAGNETIC COMPATIBILITYAbility of a device or system to function in a given electromagnetic environ-ment without generating electromagnetic fields that can disturb that envi-ronment

IMMUNITY OR SUSCEPTIBILITYAptitude of a device or system to function without degradation in thepresence of electromagnetic disturbances.

It defines:the procedures for measuring interfering signals generated by data processingequipment

It specifies:the limits for frequencies ranging from 0.15-1,000 MHz (limits of terminal inter-ference voltage, limits of radiated field of interference, limits of interferencepower) for class A and B devices.

It describes:the general conditions for measuring interference voltage at the terminals of theradiated interference field (measurement receivers, antenna, ground plan, testsite, etc.)


The interference may be:

conducted transient radiated HF permanent LF

Conducted interference is characterized by its electric current and DDP.Radiated interference is characterized by its electrical and electromagnetic fields.Permanent interference pollute primarily analogique circuits.Transient interference mainly pollutes digital circuits.LF < 1MHz, HF > 1MHz.

They are applied to active equipment. The cables, connectors and wiring systemare concerned only if they are connected to active equipment. An unshieldedwiring system can improve transmission or reduce immunity. Electromagneticcompatibility therefore applies to a wiring system with its connected terminalequipment.

Field of application

Types of interference

Information systems:

Computer networks are designed to function with a certain error rate.

Errors generate the renewal of operations (transport layer).

Errors increase running time.

If the error rate is too high, the network will become saturated.

Telephone:

Unintelligible messages

Effects of interference

Radar, HF transmitters, high-voltage lines, lightning, etc.

Medical equipment, welders, mobile phones, walkie-talkies, dischargelamps, electric motors, etc.

Fluorescent tubes, etc.

Origin of interference

Interlinking of grounds

30 cm separation between interfering strong and weak currents (except forshielded cables if the strong and weak currents supply the same equipment,which limits the ground loop surface areas).

Note: this is a new rule which modifies the 30 cm rule which now applies onlyto shielded FTP cables, not UTP!

Use shielded cables (grounded at both ends)

Use solid metal cable trays (ground plan = reduction effect)

Fiber optic wiring is regulated by standard EN 50 173. Its use is becoming moreand more frequent as the gap between the cost of fiber optic cables and twistedpair cables is narrowing. The installation of the former is becoming simpler whileinstallation of the latter is becoming more complex, especially for the frequen-cies of the new standard at 200 and 600 MHz. While the all-fiber-optic era is stillfar away, the mixed use of copper and fiber is now feasible on both economicand technical levels.Fiber optic cabling is organized either on a point-to-point basis (horizontal cablesor between distribution frames) or in a star topology from a general optic distri-bution frame (campus or building).

The use of fiber optic cables may be considered in the following cases:

network with frequencies > 300 MHz

connection of long backbone cables in large buildings (over 100 m)

capillary links > 100 m

interconnection of buildings (to solve ground equipotentiality problems andpower surges due to lightning)

sites with high electromagnetic pollution (above the required EMC standards)

specific cases requiring information confidentiality

interconnection of remote autoswitches

Fiber optic wiring includes some or all of the following elements:

standardized fiber optic connectors (F101130, F201230): type ST, SC, singleor double

vertical fiber optic cables (building backbone cable) or inter-building cables(campus backbone cable). MNC6FO, MNC6FOB

organization systems: these consist of fiber coiling and spreading units as wellas connection supports (see section 3.4)

*Note: On short links, make sure that the optical power transmitted does notsaturate the receivers.** The standard also enable monomode fibers but gives preference to multi-mode fibers, easier to connect and whose performance is more than sufficienton service sector or industrial sites.

Patching can be done either:

by using optical heads mounted on the distributor frames (P/N 5460)

or by using optical modules mounted in 19" racks (P/N 6660)

The former are usually reserved for small fiber optic networks (a dozen fibers)while the latter are used in large fiber optic networks with a direct connection atthe optoelectronic outputs.

Connector attenuation:

Maximum attenuation on the average of connectors: 0.5 dB (maximum for aninsulated connector: 0.75 dB)

The use of fiber optic capillary cables has long been prohibitive because ofeconomic rather than technical reasons. There were no optimized, reliablecomponents to supply workstations at a low cost. The situation has now changedwith the advent of Powerlight.

This cable includes 4 screened quads, Cat. 6 plus two fibers and a pair for remotesupply (for optoelectronic interfaces). With a very small volume (Ø 0.8 mm), thiscable simultaneous supplies:

2 optic fibers

1 RJ45 connector, category 5 or 6

1 remote supply pair (this additional 0.8 mm diameter pair can also be usedfor the telephone or building technical management system)

Fiber optic wiring is easy and there are numerous components on the market.Nevertheless, they are associated without being optimized. The resulting costsare usually prohibitive or the functions offered are limited. The new techniquedeveloped by INFRA+ offers the following advantages:

Because of their design and modularity, all the components are designed tocreate top-performance, easy to install workstations. Fiber pulling is free since itis done at the same time as the copper wire. All the components are standar-dized, therefore produced in large quantities by many suppliers at competitiveprices.

This is the possibility of installing fiber optic cables for later use (the ends of thecable are connected only when the need arises). The cost of this technique isequivalent fiber production cost , except that in this case the fiber is in place andready to use.

The "all optical" connection presents a serious drawback when it comes to theworkstation socket: it is fragile. Affordable optical patch-cords found on the marketare useable only in service rooms. They do not have much resistance to mecha-nical limitations (knocks from chair casters, brooms, feet that get caught in thecables lying around, cables stepped on, etc.)

The face plates are designed to receive optoelectronic interface boxes whichtransform the optical signal of the fiber into an electrical signal which is directlyusable by the active equipment and workstations.While there is more and more equipment on the market with an optical output,these machines cost much more than comparable equipment with an RJ 45output, for the simple reason that they are produced in smaller quantities. There-fore, it is much cheaper to generalize active equipment as all electrical. Further-more, RJ45 patch-cords cost five times less than optical connection patch-cords(4 patch-cords are needed to connect a terminal to equipment via a backbonecable). Networks included: Ethernet 10/100 Mbits, GigaEthernet 1000 Mbits, ATM625 Mbits.

Fiber optic backbone cables can be composed of mixed Powerlight cables (2 FO+ Cat. 6 pairs). This is a high performance solution for sites that require only afew fibers. For larger sites, conventional all-fiber-optic solutions are used.INFRA+ fiber optic components for the backbone cables can be set up in two ways:

Wiring done entirely on site:This set-up requires highly qualified installers equipped with testing equipment

Use of pre-connected backbone cables in SC or ST:This set-up is cost-efficient and rapid and can be applied to both small and largesites. In addition, it is very reliable, since the backbone cables are prepared andtested in-house. The only operation that has to be done on site is to unroll thecable and put the connectors in the optical modules.

4. ENGINEERING RULES CONCERNING 230 V ELECTRIC DISTRIBUTION

The power supply to office workstations must meet the following criteria:

connect each distributed circuit to a 30 mA differential circuit breaker placedon the floor or area panel

have a sufficient number of sockets. The ideal situation is 2 PCI (computerpower socket) and 4 PCO (ordinary power 230 V sockets) for each worksta-tion. Even if the 230 V computer network is not backed-up, it is recommendedto make a separate distribution network from the ordinary sockets

choose an average power of 400 W per workstation, and 10 workstations(800 W with double distribution)

Factory-made INFRABUS daisy chains (see section 6.2) offer significant advan-tages: all you have to do is unroll them and clip them into INTEGRATION 45 trun-king systems. For medium and large buildings, this technique generates consi-derable savings as far as on-site manpower is concerned.

If you wish to back up the power network to be used for computer terminals,it is necessary to differentiate the sockets that will be used for computerequipment from those which will be used for other equipment. There areseveral possibilities:

visual foolproofing (different colored sockets, yellow for example with thewords "backed-up network" or "computer socket"). This is the solutionrecommended by engineering and design consultants.

discrimination through mechanical foolproofing (originally created withrespect to the waiver to article 532.2.6.1). This solution is now outdated.

The most economical solution is visual foolproofing which is very efficient as longas there is an adequate number of workstation sockets: there must always betwice as many ordinary sockets as computer sockets to avoid errors in choosingthe wrong network. Two 230 V computer sockets (yellow) and 4 ordinary socketsseems a judicious choice.

There is no distinction between the computer sockets and the sockets for otherelectrical equipment.

There are three types of distribution networks to supply workstations. Only thefirst two are still used; the third (without differential circuit breaker) is no longerused.

4.1

SPECIAL FEATURES OF 230 VOFFICE EQUIPMENT

NETWORKS Non-backed up network

Backed-up computer network


According to a waiver to article 532.2.6.1 of French standard NF C 15 100, it isnot compulsory to protect circuits that connect fixed equipment, includingcomputer workstations, with 30 mA differential circuit breakers. In such a case,the use of sockets with foolproof mechanisms is compulsory. Implementing thiswaiver, however, requires a written authorization from the company manager,since this provision is binding on the building owner and is contrary to commonpractice. In practice, this waiver is never used and has become obsolete.

Mechanical foolproofing is an outdated technical solution and is more costly. Itis of interest only if the foolproofing is truly tamper-proof, which is rarely thecase, and if the manager can forbid the use of extension cords and ordinarymultiple plugs allowing undesired connections. Mechanical foolproofing is notstandardized and is only found in France.

Network without any differentialcomputer protection

For human protection, French standard NF C 15 100 makes it compulsory to use30 mA differential circuit breakers on circuits supplying electrical sockets.

As stated in the new standard EN 50174, there must no longer be any distinc-tion between computer ground and electrical ground. We must now consider thatthere is only one ground network in the building, with maximum interlinking ofall metal parts (particularly cable trays which ideally should be made of perfo-rated metal). The safety of electrical and electronic equipment is ensured bymaximum equipotentiality inside the building and not by ground resistance.

Earthing

A fundamental EMC rule consists in bringing together the cables supplying thesame system in order to reduce loop areas (inductive coupling). This necessi-tates the use of shielded data cables in order to avoid any interfering induction.

Note: this new stipulation contradicts the traditional rule of a 30 cm gap, laiddown in the 80's when there were only low rate networks likely to be disruptedby the 50 Hz LT network.

Reduction of loop areas

The recommended neutral rating is TN-SNeutral rating

4.2

RECOMMENDATIONSCONCERNING EARTHING


This standard is mentioned for information only. It constitutes the standardsbasis for the electrician's work.

An overall appraisal, especially concerning earthing problems and electroma-gnetic interference, is now carried out by professional bodies such as the F3i andFNEE. These organizations have laid down new state-of-the-art rules that shouldbe referred to (Standard EN 50174).

INFRABUS technology entirely complies with the new stipulations of the stan-dard.

The most convenient type of distribution is the trunking system. It must simul-taneously take up little space and offer a large volume for running cables. For thispurpose, the INFRA+ trunking system offers top performance. It also makes itpossible to install factory-made daisy chains with 1, 2, 3 or 4 sockets per works-tation (with ordinary sockets or backed-up sockets for computer equipment).

WALL-MOUNTED ELEC-TRICAL DISTRIBUTION

FLOOR OR CEILING ELEC-TRICAL DISTRIBUTION

There are 4 main methods of distributing 230 V power in office spaces:

Direct or cascading power supply from the distribution panel

Star distribution through connection boxes attached to cable trays

Distribution by factory-made raceways

Distribution by factory-made INFRABUS bus.

These methods are all very different in terms of flexibility within the space (addedvalue of modern upgradable offices), reliability and cost. Paradoxically, manyprofessionals are still ignorant of the advantages and diadvantages of the varioussolutions or do not know how to get the most out of them. This situation is dueto insufficient knowledge of the technical possibilities offered by standard C 15100 and improper use of differential circuit breakers.

In order to give you an overall view of the technical possibilities offered byINFRABUS, we will first review the various techniques currently available.

Direct or cascading power supply from the distribution panel:This small-scale technique is presented as a reminder. Because of its cost, it isstrictly limited to very small sites close to household proportions. For safety, thesame rules should be applied here as for households.

30 mA differential circuit breaker

2.5 mm2 wires

Beware of preconceived ideas

It is very frequent to meet electricians who

think that the number of sockets on one

electric circuit must be limited to 5 or 8 in

the service industry. This is totally incorrect:

these limitations are those of PROMOTELEC

and French standard NF C 15 100, respec-

tively, and concern only residential premises!

In the service industry, the only restrictions

are the following:

the intensity supported by the cables

the limits of the differential circuit breaker

sensitive to current attuenations generated

by computer equipment (the standard

allows a maximum of 1.5 mA but in prac-

tice, current attuenations do not exceed

0.5 mA. On a circuit breaker which cuts

out at 18 mA, the theoretical limit would

be 36 machines.)


Star distribution by connection boxes fixed to cable trays

This traditional solution (80 % of the market) is not fully optimized as far as costand duration of installation work are concerned. It implies pulling long lengthsof cables and considerable on-site manpower. To lower costs, installers often haveto call on poorly qualified workers.

Distribution through factory-made raceways:

Before the invention of the INFRABUS, distribution by factory-made sheaths wasthe only "industrial" technique used. It came from the industrial sector where itis used to distribute power to machines. It complies with EN 60 439 2 standardsand its installation conditions are indicated in the UTE C 15 - 107 guide. This tech-nique has a certain number of drawbacks:

high cost of raceways and accessories

the workstations cannot be connected directly (specific sockets needing exten-sion cables)

if you want to distribute power to more than 10 workstations, differential circuitbreakers must be installed on each socket box (the protection devices arespread throughout the building and their cost cannot be written down toseveral workstations)

maximum of 2 electric circuits per raceway

minimum under-floor height of 80 mm and the need for adequate flatnessof the concrete.

with the owner, determine the maximum area (S) needed for the worksta-tion to be connectedaccording to the composition of workstations, e.g. 1 workstation for 15 m2

determine the parallel spacing (E) of the INFRABUS cable trays (whosesockets are at a 3 m pitch), spacing = S/3

Technological progress of high capacity networks is continuing. Computer equip-ment and active network product manufacturers have announced the introduc-tion of new equipment requiring much higher data rates than those included instandard EN 50 173 in Class D.

Task force No. 3 of the ISO/IEC JTC 1/SC 25 has therefore decided to introducetwo new classes and categories for twisted pair cables. The standards procedurefor the two frequencies adopted (200 MHz in class E and 600 MHz in class F)is identical to that of standard EN 50 173.

Intent on keeping its technological patch-cord on this market, INFRA+ is offeringthree new connectors:

The very high performance levels reached by these devices is due to a new set-up principle which makes it possible to use extremely short wiring as well as effi-cient shielding. At such high rates, the fundamental problems are set-up relia-bility and connection reproducibility.

These new connectors come with a range of new cables. They consist mainlyof the POWERQUAD cable available in 100 and 120 Ω, the GIGAQUAD in 100 Ωand MNC GIGAMULTI screened by pairs separate from the shielding braid, withsimilar performance levels as conventional PimF braided cables.

5. TRANSMISSION PERFORMANCE


The performance of transmission cables can be expressed in number of dBs: thesignal/noise ratio, or attenuation-to-crosstalk ratio (ACR) is calculated using thedifference between cross-talk and signal attenuation over 100 m. To operateadequately, the various networks on the market require a limited ACR. The tablebelow indicates, from left to right: the frequency band, connection code,minimum ACR required for proper operation, minimum Class D standard value,ACR and safety of IBCS class D 100 MHz. This safety margin is even higher isclass E and F!

ACR is the fundamental transmission performance parameter

Attenuation (Loss)

When a signal is transmitted on a line, signal attenuation along its course resultsin a lower level at the receiving end than at the origin. It is measured in dBs (deci-bels). The lower the value, the better the connection.

Restriction of attuenation:

Length of cables (the shorter the cables, the better the transmission)

Compliance with cable installation rules (compression of insulation causesan impedance mismatch that lowers transmission quality

Quality of connectors

Quality of connections (use of proper tools for connection and disconnec-tion. P/N 9151, 9154)

NEXT NEAR-END CROSSTALK (dB)

When a signal if transmitted on a circuit, part of the energy crosses over to a neigh-boring circuit (line noise). If the noise level is high enough, it will mask thecomputer-readable messages.

Controlling crosstalk:

Quality of RJ45 connectors (compensation of coupling due to the particularlayout of the pairs)

Aptitude of the end devices (RJ45, modules) to be connected withminimum untwisted lengths: these values must be below 13 mm

Cable laying: away from interfering elements (fluorescent lights, electricmotors, etc.)

ACR (dB)

Difference between the noise level (cross-talk) and the level of the signal received(attenuation). This value is expressed in dB (decibels) and must be as high aspossible.

To support a full duplex transmission on 4 pairs (e.g. gigaEthernet at 1000Mbps), two new parameters must be taken into account: powersum NEXT(PS NEXT) and powersum FEXT (FEXT) whose effects are explained in thefollowing diagram:

It is indispensable for the network manager to know the operating limits of stan-dards for the various networks on the market.

These limits are given to ensure proper operation with safety margins enablinga normally "polluted environment" to be confronted.

The operating limits for a single standardized network may vary according to thetype of terminals, active components of the network, electromagnetic environ-ment, load on the network and of course, the quality of the wiring.

The greatest merit of the standard has been to emphasize the importance of thesignal/noise ratio as a criterion in the transmission performance of ready-wiredlinks.

IBCS category 6 connections give excellent transmission performance levels,making the INFRA+ offer one of the best wiring solutions on the world market.Nevertheless, we must draw our customers' attention to a certain number ofproblems due to the newness of this class E at 200 MHz. There are still manyuncertainties as to details on the values of the standard, measuring conditions,suitability of field testers to the connectors they have to measure. In addition, Cat.6 is at the technological limit of connector RJ45.

Our customers and partners must take these parameters into consideration inorder to make demanding and realistic choices on both functional and economiclevels.

The nominal performance levels of Cat. 6 cables, mentioned in the technical andsales documents, correspond to averages obtained on installed links. Thesevalues are spread along a normal frequency-distribution curve as follows: valuesclose to the nominal value (75%), exceptional values (17%), below standardvalues (approx. 8%).

The aim of the nominal performance levels is to provide a precise idea of thepossible transmission quality level.

Numerous factors may be responsible for the variance in comparison to theminimum standard value, without having any impact on the operation ofcomputer equipment. These should be taken into account so that satisfactorywiring is not discarded for the single reason that the tester indicates non-compliance for certain connections at certain frequencies. We would like toexplain some of these situations in the following paragraphs.

Measurements on small lengths:

Paradoxically, it is easier to meet the standard for 90 m links than for 25 m links.This is explained by the fact that on short links, the connector crosstalk (themost penalizing on the link chain) is not reduced by cable length. It may thusoccur that some links are rejected by the tester for a weak crosstalk at certainfrequencies but with an excellent ACR on the rest of the band. This value is the"justice of the peace" of the quality of data transmission. It would be a mistaketo reject these links.

Values measured at low frequencies:

The values given by the standard (ISO/IEC JTC1 SC25 WG3 N518) are totallyuseless in relation to the operation of the equipment to be connected. Forinstance, the following values (in dB) are found:

10 5.5 57.8 52.3


It must be remembered that for a transmission system to work, it is generally suffi-cient to have an ACR between 10 and 20 dB. The safety margin provided by alink indicating an ACR of 48 dB at 10 MHz would not only be sufficient, butsuperfluous. This is all the more relevant as we now talk of the possibility ofreading negative ACR values (NEXT canceller technique). The curves of the stan-dard are obtained with a calculation in relation to what should theoretically bededucted, at low frequency, from the desired results at 200 MHz. In practice, thereare excellent cables at high frequencies (which is difficult to hold) but which showslight peaks at low frequencies. It would be absolutely ridiculous to reject theselinks. It is to be noted that the logic behind the ACR is also valid for the EL FEXT.

Inadequate tester / connectors / measuring cables

While field testers now starting to appear on the market are remarkable instru-ments, a certain number of difficult to solve problems persists. One of these isthe inconsistency between RJ45 male and female connectors or their incom-patibility with the tester. For instance, female connectors show a crosstalk ofaround 50 dB while male plugs on the market are around 42 dB at best. Thislack of consistency is very difficult to cope with in mathematical models andcan render measurements close to the acceptable limits spurious. We will mostcertainly have to equip testers with the same connectors as those of the cablesthey must measure. This constitutes a regression with respect to the universalnature of wiring infrastructures.

Technical optimization:

Manufacturers (of cables, connectors and testers) will probably make tech-nical advances to remedy current problems before the publication of the stan-dard. Connectors have become the weak link in the chain. Not only is itessential to have balanced performance levels on the 4 pairs to support fullduplex links, but it is also very useful to give preference to the most currentlinks of the 1000 base T giga ethernet. For example, on Cat. 6 INFRA+connectors (P/N 7700 E), we obtain various crosstalk performance levels:

on the most important combinations: 1.2 / 7.8: 62.2 dB (very high frequen-cies), on 1.2 / 3.6: 44 dB (Ethernet 10,100 base T)

on combinations requiring low performance levels or little used: 3.6 / 4.5:37.3 dB, 1.2 / 4.5: 46.8 dB, 4.5 / 7.8: 42.8 dB


Review of criteria to be takeninto account

Buildings:

horizontal and vertical cable trunking mode

the use of primary wiring at optional connection points lengthened by termina-tion boxes (see examples in sections 8.1.3, 8.1.4 and 8.1.9)

rewirability of cable trays

divisibility of the premises.

Sub-distribution frames:

dimensioning of the backbone cables

management of wiring by pairs (or in 2 or 4 pairs) or of optical fibers

ease in incorporating active equipment

clear identification of links and resources

protection by duplication of backbone cable paths (in case of partialdamage to a building)

immediate introduction of inverters or ASI on identifiable computer socketcircuits.

Work areas:

duplicability and adaptability of the terminal socket making it possible tomake a spot increase in the density of connectable equipment, withinrequired performance limits*

flexibility of the last 3 meters of wiring

consistency of the data socket and electric power supports

consistency with architectural, decoration and finishing choices

connection capacity for the service functions of the building (GTB, security,video...)

low voltage 230 V in relation to real needs.

* NOTE : The socket density will depend on the necessary degree of flexibility, thefrequency of personnel movement inside the establishment, the type of service desired(computer, telephone and/or video) and the design of the work stations (on columns,in trunking systems, on office walls, in false floors, etc.) minimizing the lengths ofmounting cables to the work stations.

ORGANIZATIONAL QUALI-TIES

As long as transmission performances are not perfectly managed, they remainthe main thought criteria for designers. Organizational performances are, however,less well grasped, since they require long experience in construction and its limi-tations, a knowledge of the organization of electronic systems and an ergonomicapproach to service business work stations.

The organizational qualities of ready-arise come simultaneously from:

engineering quality (see specialized design office list of the F3i) and designoffice quality accredited for attributing the INFRA+ contractual guarantee to theContracting Authorities,

the intrinsic qualities of the components used.

(The organizational qualities inherent in IBCS components are dealt with inchapter 6).


We should be realistic: high transmission performances are expensive. So the bestcompromises must be found between performances, cost and required conti-nuity. The value that best characterizes a wired connection is the signal/noise ratioat a given frequency. This depends simultaneously on:

a) the intrinsic performances of all the components used: patching connectionsystems, terminal connection systems, horizontal (and vertical) cables, patch-cords or connection to terminals. A single average or mediocre cable willimpose a moderate or mediocre overall result

b) the quality of the set-up of each. Results obtained in the laboratory are notalways those reproduced on job sites.

Note: Attractive advertisements for wiring systems or cables can be found on themarket for which characteristics up to 350 MHz and even 600 MHz can begiven. However, when the ACR at this frequency is calculated, it turns out to benegative! This means that at the end of the cable, not only is there no detectablesignal, but the noise becomes considerably higher than the signal.

Other traps: some RJ45 Cat. 6 connectors (on 1.2 and 7.8) are only in fact RJ45Cat. 5.

The main quality of a wiring system is managing consistency between thecomponents and the on site reproducibility of their performances once imple-mented. As a result of this management, INFRA+ can offer a priced contrac-tual guarantee which will satisfy the most demanding user.

INTEGRATION 45 SOCKETSUPPORTS FOR WORK

STATIONS

Constitution of a work station

The depth "P" of the supportsor boxes

Coming from the permanent creativity of INFRA+, IBCS components have beenthe subject of many patents that show their functional advantages. INFRA+ has the most extensive range of classical supports for 45x45 sockets onthe market. The implementation data sheets will be referred to (available on theINFRA+ web site: www.infraplus.com or upon request to the sales service).Since these products are very well known, we will only point out some specialcharacteristics.To make reading easier, this chapter and the products mentioned in it are givenin order in the INFRA catalogue.

How to choose well adapted supports?

The INTEGRATION 45 range includes many desktop work station supports thatmust be chosen according to the successive criteria in the following table:

Size and type of work: small areas are wired at the periphery, large desk topsrequire sockets in the middle of the areas.

Cable distribution mode: through the walls, the ceiling or the floor

Type of wiring adopted: either direct wiring between the RJ45 socket and the sub-distribution frame or indirect wiring from a standby primary ready-wiring onwhich "extensions" are subsequently connected.

Type of socket support: these solutions will be determined by the level of flexi-bility required per work station and cost.

The engineering officer (design office and/or installer) must verify the compati-bility of the chosen supports in the specifications with the RJ45 MULTI socketsand inserts, in particular for the three aspects given in detail below.

6. COMPONENTS OF THE IBCS, FUNCTIONAL DESCRIPTION, SET-UP

Limitations:

the small-model trunking system (ref. 64570 and the lowprofile box ref. 64503 to 64508) does not accept the RJ45Cat. 5, 7 and Cat. 7 cap (ref. 7700D , 7700E and 7777F).

Sheath

P

Sub-sheath


The number of stackable sockets

Stacking an excessive number of sockets does not enable sufficient mechanicalsolidity of these sockets in the support (in particular the PVC trunking system)and prevents cable passage.

The way to have cables enter

The type of cable entry should be planned on to make it possible to work easilyand quickly outside of the support.

Note : the cable over-length makes it possible to move the sockets.

If you want to validate your choices, do not hesitate asking advice from your salesrepresentative or for a sample.

The role of the covers is also to tighten the clipping separations, guaranteeingtheir holding (INFRA+ patent).

As indicated in chapter 4, the interest of the rapid connection socket resides notonly in the economy of wiring the socket itself, but also in its ability to be usedas power supply "buses" making it possible to reduce the number of electriccircuits.

Economy on the socket: connection in 10 to 15 seconds!

Connection possible with cable under power

Reliability greater than that for screwed sockets thanks to the self-strippingconnection making it possible to have a 4-point contact without interruptionof the conductor. The surface of contact on the copper wire is greater than thesection of the 2.5 mm2 conductor, thus a greater reliability than that of clas-sical screwed contacts. The reliability of the 14th socket is strictly identical tothe reliability of the first, since the conductor is never interrupted.

The intelligent electric socket: This socket makes it possible to differentiate thecomputer network (backed up or not) by freeing itself from the mechanicalfoolproofer, a solution which is costly, out of date and unreliable.

The combination of several innovations

Up until now, we were satisfied with stacking high current and low current wiringsystems, without looking for the synergies that could result from a total integra-tion of networks distributed in modern buildings. The idea of INFRABUS is to opti-mize the high current cable trays in order to associate with them the lower costof a prefabricated electrical power supply and annex networks.

6.3

INFRABUS the advantage of a global

VDIE approach


INFRABUS is a system making it possible to have:

1. 230 V electric power supply for networks of ordinary sockets (PCO) or for dedi-cated computer sockets (PCI) or other networks (for example, lighting), seesection 4.1,

2. The computer and telephone distribution by independent clip-on boxes, seesection 6.1,

3. The distribution of field buses or service functions of the building (field buses,video surveillance, ventilators, radio emitter bases, etc.), see section 6.3.

Applications

This mode of desktop ready-wiring is designed for cable tray wiring:

through the floor: Primary distribution sheath with derivations by boxes in the raised floor (min.

height 50 mm)

through the ceiling: Primary distribution sheath with derivation by columns of the INTEGRATION

45 type. This makes it possible to realize significant savings of 30 to 50% of the overall

230 V distribution cost.

design savings: repetitive models, overall engineering, design using softwareon CD ROM.

savings during installation: kits prefabricated in the plant, quickly assembledat work sites

savings during building operation: modularity, flexibility, easy maintenance

argument for marketing rental or promoted property: progressive equipmentof work stations according to the occupants.

The high current part of INFRABUS can incorporate a GTB field bus (1 to 4pairs), either ECHELON or similar.

Components of the INFRABUS 230 V distribution system

230 V electric distribution bus

Realized from daisy chains mounted in profile P/N 63760E

Ideal for raised floors: same functionality as prefabricated sheaths, ex. CANALIS,

economic = fast implementation, a single 30 mA differential circuit breaker for5 to 10 work stations,

with hatches (P/N 6510) under the carpeting, it constitutes the best VDIEdistribution system for raised floors having a low height (see pages A6 and A7of the catalogue).

In order to constitute an electric distribution bus, the number of work stationsto distribute and command must be counted:

1) the aluminum profile 63760E (delivered in packages of four 3-meter lengths)

2) PCO and PCI daisy chains for 5 and 10 work stations

3) covers with length L1 (plan on as many as there are 63760E profiles)

4) accessories:- end fittings ref 6609 (plan on 2 per bus)- covers ref. 7795 (plan on as many of them as there are PCI/PCO work stations)- accessories for fixing to the floor, ref. 6515 (foresee as many as there arework stations).

- accessories for fixing to the cable trays ref. 6623 (foresee 2 by profile63760 E).

Note: length L1 of the cutout covers takes into account the number ofsockets, the cover separating the PCO and PCI and the end-fittings (seeassembly instructions). The last cover will be adjusted on the site.

Standards aspects- rules of the art

The following standards are applicable

The main components (HO7 v - U 3 x 2.5 mm2) of the Infrabus/2.5 mm2wire section and PCO and PCI sockets are standardized and labeled NF (NFC61303 / CEI 884-1). Sheath protection index IP 20.

They correspond to the connection to low power machines (desktop, lighting,etc.).NFC 15-100 low voltage electric installation rules.NFC 15-520 raceway - installation mode (guide).NFC 61-602 appliance grouping..

The INFRABUS system is functionally similar to the one of prefabricated singlederivations on a single or three phase raceways in all the distribution diagrams(TT, TN-S, IT). Standard UTE C 15-107 on prefabricated raceways, however, isnot applicable for wires and sockets (10-16 A, 3 poles).

EMC

In compliance with European Directive 89/336 and 92/31 as well as professionalrules of the art (recommendation F3i - 3rd edition. Electric power supply ofwork stations).

30 A differential protection

It is recommended not to disseminate 30 mA differential circuit breakers in theinstallation, but to centralize these differential circuit breakers on the distributionpanel where they are the most accessible and easily found. This arrangement isalso more economic since it divides the cost of differential circuit breakers by thenumber of work stations in the circuit. In INFRABUS, it is recommended to have10 ready-wired work stations on the same differential circuit breaker (8 of whichare generally used simultaneously), which is compatible with the maximumcombined leakage current generated by computer hardware: 0.5 mA (manu-facturers' standards plan on 1.5 mA max.). If a circuit breaker is triggered between18 and 22 mA, it would be possible to have practically thirty sets of equipmentgenerating leakage currents.

Electrical engineering, number of sockets per circuit

In the service sector, the number of sockets per circuit is limited only by the circuitcurrent (20 A). Limitations concern only residential dwellings (8 sockets for theNF-C 15100 and 5 sockets for Promotelec recommendations). INFRABUS cansupport 10 work stations with 2 to 4 sockets, i.e. is up to 40 sockets per circuit.Distributed power: the average/max. power of the work station is about 500 Won PCI* (computer power socket) and 500 W on PCO** (ordinary power socket).As an indication, the total power for an average desktop work station is about 200to 400 W for computers and 100 to 1000 W for ordinary equipment.

* PCI: 10/16 A socket - 2 columns + ground: dedicated to computer electric power supply network** PCO: 10/16 A socket - 2 columns + ground: ordinary


This type of socket and insert are the ones most sold on the French marketbecause of the many advantages offered:

Compatibility with 45x45 mm, 22.5x45 mm and 50x50 mm formats (withadaptation frames).

The adaptable 45x45 mm inserts incorporate a place for adding an opticalconnection.

Compliance with the standard: direct connection in RJ45 of 80% of the linkson the market (without face plate or adapter).

Duplication of connected links on the same socket, making it possible todouble or quadruple the number of terminals connected (1 or 2 pairs).

Unlimited adaptability to all models of connectors for all computer and tele-phone equipment on the market

High transmission rate performance, greater than Cat. 5, Cat. 6, Cat. 7 andoptical.

The connection of RJOPTO connectors depends on the structure of the wiringused. This differs with respect to the type of screen (generally per quad or perpair), bend radii, existence of a sub-sheath, screen drain; etc. (see section 6.6).Installers must follow training program No. 3 (see section 8.4). The acquisitionof know-how by the installer totally determines all the guarantees granted byINFRA+.

As an indication, the diagrams below show the parts composing the RJ45 Cat.6 P/N 7700E connector, and the successive phases of its connection to a cable(for more details, see page 91).

Note: In case of connection error of the 7700E or 7777F keystones, they canbe taken out of their 45x45 mm or 22.5x45 mm support by using a fine screw-driver as a lever. The keystone to be changed is not reusable. In order never tohave to change the keystone, it is advisable to verify that the color code isrespected before cutting the cables and inserting the cable organizer into theconnector.

The line of MNC cables is the leader on the French market (in volume as wellas in performance) for all categories, 100 and 120 W included.

It meets the basic criteria for choice, which are:

the signal/noise ratio for high rate applications,

the aptitude to receive equipment with various impedances,

electromagnetic immunity (all MNC cables are screened).

There is a table in section 2.2 giving the performances of the links as well as theircosts. To allow you to choose knowingly, INFRA+ has made available to its part-ners complete test reports for all cables in the line (values of different frequen-cies for various wavelengths, curves). In order to obtain them, connect to theINFRA+ web site: www.infraplus.com, or ask the sales department).

The cable can be easily unrolled (reel) in order to avoid twisting that couldcause impedance inequalities detrimental to high rate transmissions.

Be careful of crushing (do not walk on the cables).

It is recommended to place the cables on cable trays. However, if you haveto pull them:- protect attack of the cable tray (foam sheaths, electric PVC tubing, etc.)- when drawing, it must be accompanied when stuck in a difficult passage- do not pull it using several persons so that "it comes".

Respect large curve radii (min. 6 to 8 times the diameter). "Be careful of usingsmall raceways".

Foresee changing direction on a minimum of 1 meter in order to avoid twis-ting.

The clamps will be tightened by hand, placed about every 2 meters horizon-tally and every 1 meter vertically.

If the cables are coiled in the ceiling or floor, the coil Ø should not be less than1 meter.

Standard 93 mmaluminum rail

distribution frame

Organizationof the number of modules:

The ease in exploitation can be verydifferent from one distribution frame toanother. It depends on the number ofmodules and their organization.

the general telephonedistribution frame: plan on 2 pairs per station, that is4 stations per cut-off module, 8pairs of 16 mm thick.

computer or mixed sub-distribution frames: plan on4 pairs per computer socketor, more generally, two times4 pairs per mixed work station,thus per 16 mm thick module.

Dimensioning a distribution frame:

The useful rail length (in mm) supporting the connection system is calculatedaccording to the following formula:

L = (number of modules x 16 mm) x coef. 1.5

This length will determine the size of the chassis or frames that will infer the typeof distribution frame:

monorail wall chassis, double rail wall chassisor self-carrying frames.

The great exploitation problems of distribution frames always come from theexcessive density of the modules, which causes:

a saturation of the cable duct

an uncontrollable volume of patching cords or jumpers

There is only one cure: aerate the distribution frame to allow it to have a betterfunctional distribution in module spaced blocks and the addition of comple-mentary backbone cables judiciously canalizing the fluxes of the patching cords.

RJ45 panelin 19" rack

Some rules for constituting a 19" rack:

Plan on 20 to 30% reserves

Aerate the distribution frame with cable guides, etc.

Place the hubs near to the distribution panels (in order to decrease cablelength) and in the chassis corresponding to the zone (do not concentrate thehubs on a same distribution frame; distribute them).

The design grid for 19" cabinet and chassis makes it possible to place the socketpanels, cable guides, fillings, active equipment, the 230 V power supply panels,etc. and to make an inventory of all the necessary components.

This is a complete line of RJ45connector panels and accessoriesoffering modular functions, unknownup until now on classical equipment:

Duplication of 1 or 2 paircomputer links.

Individual marking of workstations by cover label holder.

Functional differentiation ofconnections by color codes (blue:work stations, green: backbonecables, yellow: computer resources).

Optimized storage of excesslengths of patch-cords.

Unlimited adaptability to incom-patible heterogeneous RJ45 linksby the addition of standard orspecific adapters.

230 V power supply panels.

Up until now, the designer had to make a contradictory choice between twoconnection systems:

either by RJ45 Cat. 5, 6 or 7 panels, an ideal solution for computers, makingit possible to have a direct connection of active equipment in RJ45 networks,but unsuited for the connection of 1-pair telephone jumpers and multi-pairbackbone cable wiring (the patching connection systems using RJ45 hasalready been dealt with in section 6.7 and so we will discuss here only patchingby module on a 93 mm wide aluminum rail)

or by Cat. 5 or 6 modules: an ideal solution for telephones and computers buthaving the disadvantage of requiring an adaptation for the connection of activeequipment in RJ45 networks.

INFRA+ offers not only both these options, but also the possibility of optimizingthe wiring by mixed wiring.

Blue module: connection to work stations.Strictly telephone ready-wiring is no longer installed (except to the general distri-bution frame). It is recommended to systematically plan on 2 x 4 pairs per workstation, i.e. one work station per blue module.

Green module: connection of backbone cable multipair cables.Dimensioning the backbone cables and sources must be determined by thedesign office with respect to the specifications.

Yellow module or data port: connection of computer resources and networks.Their choice is directly linked to that of the telecom and computer equipmentto be connected.

Red module: GTC/GTB or other personalized application.

Color codesand estimationof wiring needs

Mixed modules /19" rack distribution


Ensure that the components have not deteriorated during transportation andinstallation.

Verify the performances of the installation and its compliance with class D, E or F.

Note the elements necessary for managing the installation:- identification of connection systems and cables,- length of links.

It is important that the user be able to verify the performance level of his struc-tured wiring in to be certain that the equipment connected to it will operateperfectly.

Considering the very high performances required in category 6 and the lowmaneuvering room for builders and installers, a realistic interpretation of the indi-cations given by the worksite testers has become an obligation (much more sothan for Cat. 5 which offers a generous ACR margin). For problems concerningtest interpretation, also see chapter 6 concerning transmission performances.

This interpretation of test limits requires from the persons concerned, certifier,design office, installer (and also contracting authority), a technical competencebased on experience and pragmatism.

In general, inspection and validation include the following steps:

7.1

AIMS

Environmental limitations.

Cable curve radii.

Min. sheath removal lengths.

Min. rectified split lengths, twisting less than 13 mm.

Absence of split parallel wires.

Identification of connectors.

Earthing screens, distribution frames and all shielding elements.

7.2

VISUAL INSPECTIONS

7. INSPECTION AND VALIDATION OF THE INSTALLATION


The standard provides for limits per installation classification in terms of atte-nuation and crosstalk. If one of the two parameters is not fulfilled and thesignal/noise ratio complies with the limit values, the installation is consideredas being compliant.

The difficulty in obtaining class D results primarily from the near-end crosstalkwhose defects result from:assignment of pairs on the RJ45 contacts (3/6 and 4/5 pairs),connection to the connectors (excessive untwisting with parallel path).

Problems encountered:

Insufficient sensitivity threshold:

- 10 meters MNC at 16 MHz = 0.6 dB- device threshold: 1 dB

Measurement accuracy:The testers all have a margin of inaccuracy. (Tolerance of the measurementwith respect to the nominal value defined in the standard).

There are two categories of testers:- Level 1: accuracy of measurement: + 4 dB- Level 2: accuracy of measurement: + 2 dB

It is important not to be content with the sanction displayed on the test screen:PASS or FAIL, but to verify the ACR level which is the only element capable ofguaranteeing system functionality.

Consideration ofthe electrical parameters of

the installation

Use of testerson the market

The purpose of the static tests is to verify that each twisted pair, the basic infor-mation carrying element, complies with the installation plan, namely:

that is it correctly linked at each of its ends,

that its continuity is not interrupted,

that its polarity is correct,

that no short circuit has been provoked between its two conductors,

that its insulation with respect to other pairs and the ground has been maintained,

that both wires composing it are the ones of the same pair (splitting),

that its identification (geographic marking) on the installation plan correspondsto reality.

7.3

ELECTRICAL INSPECTIONS

Static inspection

The standard provides for measuring the electric characteristics of the horizontaldistribution between the wall socket and the connector of the connections ofactive components (yellow modules).

Dynamic inspection

The role of the design office in charge of engineering is not to present an exten-sive reception dossier, but to provide an interpretation to the contracting autho-rity. This is valid for class D wiring (category 5 components) an so this stipula-tion becomes indispensable for category 6.

In Cat. 5, serious wiring has a comfortable margin of safety (from 10 to 20 dB),while in Cat. 6 we are very close to the performance limits of the RJ45 connec-tors. As a result, some links (for example 10%) could turn out to be at the limitof performance with respect to the standard, while remaining perfectly functional.

Rejection of these links by the work site tester could arise from many secondaryreasons: limit crosstalk at certain frequencies, imprecision of the tester at lowfrequencies, inadequate programming of the tester (generally according to theEIA/TIA values and not European Standard ISO 50173), test cord with low perfor-mance, excessive effect of RJ45 connectors on the short links (crosstalk is notattenuated by the cable).

Rejection by the tester in no way means that the tested link is functionally bad.It only implies that one of the parameters is below a programmed value. If thisvalue is not of fundamental importance or the deviation is small and concernsonly a small number of links, then they should be accepted.

Note: A realistic interpretation of wiring performances requires that all the profes-sionals involved, Design Office, Certifier and the Contracting authority, have thenecessary skill and experience.

Analysis and interpretationof test results

Note: The cables delivered are not necessarily compatible with the patching systems

or do not have a sufficient performance level (cables that require an excellentnear-end crosstalk quality) in particular for Cat. 6 and 7.

Influence of the work station connector for short cables.

The results provided are difficult to use.

Calculation of the signal/noise ratio done by the devices are sometimes unreliable.

The INFRA+ site makes technical and economic information available to profes-sionals that is classified into two topics: NEWS and TRICKS OF THE TRADE.

In NEWS, you will find topical information on wiring techniques, standards orproducts. In TRICKS OF THE TRADE, you will find feature articles, sales presen-tations of new products, technical notes giving the details of new technologies,the answers to frequently asked questions (FAQS) on materials, standards ormarkets. This very rich material can help you document your offers or conductin-house training. It is available to all INFRA+ partners and customers.

You can also ask all the questions you want on the web site directly to thepersons or services of your choice, who will be pleased and willing to answer youin return.

Regularly consulting the INFRA+ WEB site is an assurance that you are takingadvantage of a rapid and specialized technowatch.

8.1

TECHNOLOGY MONITORINGON THE INFRA+ WEB SITE

The IBCS is not only the first system of ready-wiring installed on the Frenchmarket, it is above all an overall solution that covers:

innovative, consistent components,

multiple services for the design office, the installer and the user,

loyal and realistic guarantees,

expert partners (installer and design office) who give the users the "sets youfree".

For all the services indicated below, the INFRA+ sales staff can provide an answeror appropriate help to all the players on the market. Do not hesitate to contact us.


The INFRA+ CD ROM is a unique tool made available to design offices andinstallers. More than a multimedia catalogue, news, a presentation of thecompany and a pedagogy part (making it possible to conduct training programs),it contains a design tool for ready-wiring and pricing which is presently uniqueon the market.

This tool was created in the framework of the main ready-wiring principles:systematic, ordinary, reconfigurable and universal.

These criteria imply that we are trying to design the most homogeneous wiringin the areas to be distributed. This is why the pricing software voluntarily limitsthe choice of different equipment within the same area which could cause diffi-cult or impossible management.

In addition, this choice of simple modeling around repetitive components makesit possible save a good deal of design time. Of course, it is always possible tomanually add everything that does not enter the ordinary wiring automaticallycalculated by the machine (service current sockets, use of parts of the wiring forGTB, specialized computer or telephone sockets in a special place, etc.).

CONCEVOIR enables rapid and complete engineering of ready-wiring, as well asthe response to calls for tenders in IBCS:

low currents (computers, telephone),

high currents (230 V distribution: ordinary, backed-up, lighting),

distribution supports in the building (flexible work stations, INFRABUS).

Up to now, most design offices were poorly equipped to respond to the engi-neering of small and medium size sites, that are increasingly numerous on themarket. In order to remain competitive, they were forced to limit themselves toconstituting price grids on spreadsheets and to copy/paste the CCTP that are notalways adapted.

CONCEVOIR enables rapid, complete and documented engineering, priced withelaborated price schedules making it possible to draft dossiers that are as care-fully drawn up for small wiring as for large installations.

The realization of advanced, high performance wiring requires taking a conside-rable number of parameters into account: technical, standardized, architectural,economic or performance. Only a calculation tool coupled with a specializeddatabase makes it possible to integrate these parameters completely and tomodel them around options that are simple to use.

USING THE CD ROMFOR DESIGNERS

AND INSTALLERS


Building study

structuring in areas around the sub-distribution frames,

positioning the SR, RG, cable trays on plans,

measurement of lengths on the plan,

transcription of all the administrative information relative to the site to bewired into CONCEVOIR.

Qualitative and quantitative description of the areas to be wired

choice of components: connection systems, supports, distribution, wiring,

dimensioning work stations (modeled A to H) and wiring organization(direct or indirect distribution).

Interconnection of the areas

Choice of design parameters for telephone and computer backbone cables.

Edition of specifications

the software makes all the calculations. It enables all types of outputs (paper,diskettes, e-mail) for consulting installers. All the information (amounts, cata-logue numbers, designation, suppliers, etc.) can be modified by the design office.

Note: The installer who responds to a consultation realized by CONCEVOIR hasno data to enter: pricing and drafting are completely realized by the software.

The various phasesin the preparation

of specifications

The ready-wired universe (computers + telephones + 230 V stand-by and ordi-nary power supply) is very complex and requires extensive technical know-how.Each building is a special case. Prior thought on the plan is mandatory. This CDROM makes it possible to realize 95% of the situations existing on the marketusing a simple model. For the remaining 5%, they can be treated by manual addi-tions to the automatically generated document. Training is advisable for learningthe tricks making it possible to save time and make the judicious choice ofcomponents.

In 1999, the CD ROM has been enriched with new software for calculatingwiring quotations very rapidly. When the basic parameters are known (numberof sockets, floors, class of rates, etc.), a quotation can be made in a few minutes.Of course, this software does not give the detailed priced nomenclature of theinstallation. For this, the CONCEVOIR software must be used.

Recommendationsfor using the software


In fields where technology changes very rapidly, updating is useful. This is whyINFRA+ and its network of partners make available to the market an entire setof training programs:

"SELLING IBCS"

How to bettersell your wiring service


When you are sure of the quality and consistency of your products, the compe-tence of the design office and the installers, it becomes possible to providecontracting authorities contractual guarantees on:

the functioning of the systems and networks that will be connected to IBCS,

compliance with European and international standards,

the long life of the installations realized,

INFRA+ assurance by a specific policy.

This guarantee is real. It is implemented at the request of any contracting autho-rity. It is the result of a rigorous procedure at the end of which a technical recep-tion will validate the perfect quality of the wiring installed and its capacity tosupport the most exacting networks, both today and tomorrow.

8.5

APPLICATION GUARANTEEFOR THE FINAL CUSTOMER

It is difficult for a design office, an installer or the technical services of a user toassemble complete, relevant information on subjects as broad as networks, stan-dards or the setting-up of the technical systems of a building.

This is why INFRA+, who participates in the activities of the main professionaland standards organizations on these subjects, offers sales assistance tools to itspartners and customers:

CD-ROM

samples and demonstration material

catalogues

product brochures

site visits (by appointment)

Technical brochures by professional organizations, such as F3i, FNEE or FICOMEand especially information updated on our web site: www.infraplus.com.
