FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form
the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental,
in liaison with ISO and IEC, also take part in the work.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for
voting. Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
3) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC and ISO technical committees is to prepare International Standards.
In exceptional circumstances, a technical committee may propose the publication of a technical
report of one of the following types:
• type 1, when the required support cannot be obtained for the publication of an International
Standard, despite repeated efforts;
• type 2, when the subject is still under technical development or where, for any other
reason, there is the future but not immediate possibility of an agreement on an International
Standard;
• type 3, when the technical committee has collected data of a different kind from that which
is normally published as an International Standard, for example ‘state of the art’.
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transformed into International Standards. Technical reports of type
3 do not necessarily have to be reviewed until the data they provide are considered to be no
longer valid or useful.
ISO/IEC 14763-2, which is a technical report of type 3, was prepared by subcommittee 25:
Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:
Information technology.
This document is not to be regarded as an International Standard. Comments on the content of
this document should be sent to the IEC Central Office.

4 Safety
The specification of safety requirements is beyond the scope of this Technical Report. It is
referred to those safety standards and regulations applicable at the location of the installation.
5 Planning
5.1 General
This clause details the recommended approach to be taken during the planning phase, prior to
the development of an Installation Specification (see clause 6).
5.2 Distributors, Transition Points and Telecommunications Outlets
5.2.1 General
The functional elements of generic customer premises cabling as defined within ISO/IEC 11801
are the Distributors (Campus, Building and Floor), the Transition Point (optional) and the
Telecommunications Outlets together with the cables used to interconnect them (see clause 5
of ISO/IEC 11801).
The requirements for the relative positioning of the Distributors and the Telecommunications
Outlets and the performance of the cabling sub-systems are detailed in clauses 6 and 7
of ISO/IEC 11801.
5.2.2 Distributors
5.2.2.1 Environmental protection
Distributors are located within areas designated as Equipment Rooms or Telecommunications
Closets. The Equipment Rooms and Telecommunications Closets (and cabinets or other
closures within them) should provide physical and environmental protection for the distributors.
This protection may be achieved either by choice of appropriate location or by specific design
features and should address the following aspects:
a) temperature;
b) humidity;
c) vibration;
d) exposure to ultraviolet radiation
e) ingress of dust, fluids (including flooding) or other contaminants;
f) chemical attack;
g) physical damage (accidental or malicious);
h) security;
i) presence of hazards;
j) electromagnetic interference.
---------------------- Page: 9 ----------------------
– 4 – TR 14763-2 © ISO/IEC:2000(E)
5.2.2.2 Location
Floor distributors should be located such that the length of the horizontal cabling sub-system
does not exceed the limits detailed in ISO/IEC 11801.
Distributors should be positioned with adequate access and should be provided with illumin-
ation suitable to allow installation and operation of the equipment and cabling contained therein.
The following recommendations are made for all cabinets or frames constituting a distributor:
a) the minimum clearance on all vertical faces where access is required should be 0,9 metres;
b) no connection points should be set at a height greater than 2,5 metres;
c) no connection points should be set at a height less than 0,15 metres.
The design, dimensions and clearances (e.g. sub-floor) of the distributors should:
d) enable compliance with relevant national or local regulations with regard to cable
segregation;
e) enable the required cables to be installed whilst maintaining the minimum bend radii
specified in clause 8 of ISO/IEC 11801;
f) enable an agreed proportion of additional cables to be subsequently installed whilst main-
taining the minimum installation bend radii specified in clause 8 of ISO/IEC 11801;
g) allow appropriate provision for the management of cables and patch cords.
Distributors should not be installed:
h) in toilet facilities;
i) boiler/plant/machine rooms;
j) in emergency escape ways;
k) in ceiling or sub-floor spaces;
l) in areas subject to flooding;
m) within cabinets or closures containing fire hose reels or other fire-extinguishing equipment.
5.2.3 Telecommunications Outlets
5.2.3.1 Distribution
Each Work Area should be provided with Telecommunications Outlets in accordance with
ISO/IEC 11801.
There is no single recommendation for the distribution and density of Telecommunications
Outlets within premises. The dimensions of the Work Area and the quantity of Tele-
communications Outlets provided are installation-specific (subject to the minimum require-
ments of ISO/IEC 11801) but the following issues should be considered:
a) local regulations may set minimum figures for the area or volume associated with the space
allocated to a person within an office environment;
b) the number of Telecommunications Outlets within each Work Area should reflect the
predicted requirements of that Work Area;
c) operational flexibility may be enhanced by the use of additional Telecommunications
Outlets.
Subsequent installations of horizontal cabling to provide additional Telecommunications Outlets
tend to be both costly and disruptive. It is recommended that:
d) planning decisions should accommodate the diverse telecommunications demands of the
occupants;
e) the detailed design and planning of pathways and pathway systems servicing the Work Areas
should aim to minimise the cost and disruption of ongoing changes to the cabling system.
---------------------- Page: 10 ----------------------
TR 14763-2 © ISO/IEC:2000(E) – 5 –
5.2.3.2 Location
The planned locations of Telecommunications Outlets should address:
a) access to allow installation and operation (disconnection and reconnection of Work
Area Cables);
b) space to house application-specific adapters (such as baluns or impedance matching
devices) which should be external to the Telecommunications Outlet, in accordance with
ISO/IEC 11801;
c) ingress of dust, fluids (including flooding) or other contaminants;
d) chemical attack;
e) accidental physical damage.
The planned locations of the Telecommunications Outlets and the design of any closures
containing the Telecommunications Outlets should enable compliance with relevant national or
local regulations with regard to cable segregation.
5.2.4 Transition Points
5.2.4.1 Distribution
A transition point provides for interconnection between horizontal cables extending from
building pathways and cables extending into work area spaces; it is not a user interface.
5.2.4.2 Location
A transition point is located between horizontal cables extending from building pathways and
cables extending into work area spaces. Transition points should be located in fully accessible,
permanent locations such as building columns, and permanent walls. Transition points should
not be installed in furniture unless that unit of furniture is permanently secured to the building
structure.
The use of suspended ceiling space or access floor space for transition points is acceptable
with the following conditions:
a) transition points should not be located in any obstructed area;
b) access to the transition point should not require occupants to relocate;
c) the ceiling or floor tile should be clearly and permanently marked and identified as
containing a transition point;
d) the transition point should be administered according to ISO/IEC 14763-1;
e) transition point connecting hardware should be protected from physical abuse and foreign
substances by an enclosure that is suitable for the environment;
f) telecommunications equipment should not be directly connected at the transition point.
NOTE When the transition point is located in an air-handling space, additional precautions may be required to
ensure that building code requirements are met.
5.2.5 Administration and polarity maintenance for optical fibre cabling
ISO/IEC 11801 recommends that accidental misconnection of different optical fibre types
should be prevented by some form of coding e.g. by the use of different colours on the
connecting hardware.
ISO/IEC 11801 recommends that polarity should be maintained for duplex communications
channels by the use of keyed connecting hardware or the clear identification of the optical fibre
interfaces.

5.3 Pathways and pathway systems
5.3.1 Planning approach
It is recommended that the planning of pathways and the selection of pathway systems is
undertaken using a structured approach and addressing each cabling sub-system in turn as
follows:
a) the Campus Backbone Cabling Sub-system;
1. between Building Entrance Facilities;
2. between Building Entrance Facilities and Distributors;
b) the Building Backbone Cabling Sub-systems;
c) the Horizontal Cabling Sub-systems.
Examples of pathway systems that may be used are shown in Table 1.
Table 1 – Examples of Pathway Systems
Location Pathway Features
Systems
Trunking/ Enclosed containment systems normally used in open office areas.
Indoor
conduit Single or multiple cable designs.
Available in metallic or non-metallic form.
Tray Open containment systems designed to house large number of cables and
normally used in floor/ceiling spaces or in restricted access areas (e.g.
basements, plant rooms, telecommunications spaces etc.).
Tray provides continuous support for the contained cable when used in
horizontal pathways.
Typically available in metallic form.
Basket Similar to tray but contains supporting bars rather than continuous support.
Normally used in horizontal pathways.
Typically available in metallic form.
Ladder Similar to tray but contains supporting bars rather than continuous support.
Normally used in vertical pathways.
Typically available in metallic form.
Duct Enclosed containment systems designed to house a large number of
cables and normally used in floor/ceiling spaces or in restricted access
areas (e.g. basements, plant rooms, telecommunications spaces etc.).
Available in metallic or non-metallic form.
Designated Pathways defined by markings or some other designation.
routes
Indoor/outdoor Catenary A suspended strength member to which single or multiple cables may be
attached in order to span an open space.
Available in metallic or non-metallic form.
In some cases the cable is designed as a catenary cable and contains an
integral catenary strength member.
Outdoor Duct Enclosed containment systems designed to house single or multiple cables
between buildings, maintenance holes and drawpits. The use of ducts
enables subsequent removal and addition of cables.
Typically available in non-metallic form.
Direct Open trench routes into which specially-designed cables are installed and
Burial then back-filled.
NOTE Where conducting pathway systems are used, the electrical continuity of the installed sections should
be maintained and bonded to earth in accordance with relevant national or local regulations.

TR 14763-2 © ISO/IEC:2000(E) – 7 –
5.3.2 Environment
The installation and operating environments within the pathways or created by the type of
pathway systems used should be compatible with both the cabling and the proposed methods
of installation.
Common factors to be considered are:
a) temperature;
b) humidity;
c) vibration;
d) exposure to UV;
e) chemical attack;
f) accidental physical damage;
g) security;
h) presence of hazards;
i) electromagnetic interference;
j) rodent damage.
NOTE 1 Certain environments may place restrictions on the use of fusion splicing of optical fibres (which generally
use an open electric arc).
NOTE 2 Requirements for levels of toxic or corrosive gas emission, smoke generation and flame propagation of
the installed cabling during combustion should be determined and may be subject to national or local regulation.
The pathways and pathway systems should be selected following consideration of:
k) the method of attaching the selected pathway systems;
l) the loading of the pathway systems both by the weight of the proposed quantities of cable
and the proposed methods of cable installation.
Where possible incompatibility exists then alternative routes, pathway systems or components
with enhanced environmental (or other) characteristics should be considered. Failure of
alternative routes to comply with the length requirements of clause 6 of ISO/IEC 11801:1995
may necessitate the establishment of additional distributors or the use of alternative cable
types or media.
5.3.3 Dimensions
The points of cable entry to the pathways should be located to provide space for any equipment
required for installation (including cable drums and drum stands) and should enable installation
of the cables whilst maintaining the minimum installation bend radii specified in clause 8 of
ISO/IEC 11801.
The dimensions and types of pathways and pathway systems selected should:
a) enable compliance with relevant national or local regulations with regard to cable
segregation;
b) enable the initial quantity of cables to be installed whilst maintaining the minimum bend
radii and not exceeding the cable pull strength specified in clause 8 of ISO/IEC 11801;
c) enable an agreed proportion of additional cables to be subsequently installed whilst
maintaining the minimum installation bend radii and not exceeding the cable pull strength
specified in clause 8 of ISO/IEC 11801.
---------------------- Page: 13 ----------------------
– 8 – TR 14763-2 © ISO/IEC:2000(E)
The pathways constructed using tray should:
d) provide an agreed minimum clearance from the surface to which it attaches;
e) provide an agreed minimum working space above the tray to enable access during cable
installation;
f) use pre-formed bends, compatible with the pathway, to perform changes in direction.
5.4 Earthing and bonding
ISO/IEC 11801 contains requirements for the earthing and bonding of generic cabling
components. The provision of appropriate earthing and bonding points should be considered
during the planning phase.
6 Installation specification
6.1 General
An Installation Specification should be produced by, or on behalf of, the user and should be
agreed with the installer prior to the commencement of the installation. This clause details
aspects which should be covered within the Installation Specification.
6.2 Operational requirements
The Installation Specification should contain specifications relating to operational requirements.
In order to meet overall telecommunications requirements, it is recommended that the following
aspects be addressed.
Topology: detailing the locations of the distributors, Transition Points, Telecommunications
Outlets, pathways and pathway systems together with the number of cables
required within each pathway.
Hazards: providing relevant information and drawings clearly identifying the boundaries of
hazardous or potentially hazardous areas within the p
