Introduction
Telecommunications is more than just voice and data. Telecommunications takes in many
other building systems including Climate Control for heating, ventilation, and air
conditioning, Lighting Management for increasing efficiency costs, Security for access
control, surveillance and intruder alert monitoring, and Audio for public address.
Indeed telecommunications can carry all low voltage signal systems that control
information within the intelligent Building and modern structured cabling systems, such as
the KRONE PremisNET C
3
Solution, can Control, Command, Communicate, and
consolidate all these individual building systems.
During the life of a building, additions and changes have become more the rule than the
exception. The traditional method of proprietary cabling that supports individual building
systems, can no longer support the increasing demands put on to the building owners by
the occupants. The KRONE PremisNET C
3
Solution addresses this problem in a positive
way. The Intelligent building cable infrastructure can be future proof designed and
installed to benefit everyone.
Standards
Planners, Developers, Consultants and Architects are not left empty handed: there are
extensive and sophisticated standards existing which help in designing and implementing
building cabling systems. These communications standards define the minimum structure
to deliver voice and data services to the desktop in accordance with the above standards.
The relatively new concept of the consolidation point can be incorporated into a horizontal
cabling design where cabling density is significant or where excessive configuration
management activities are required due to staff or equipment movements. This element
can be compared with the final distribution point or FDP used in block cabling distribution
for voice services.
This approach is developing acceptance across the market but there are few vendors that
offer a range of consolidation point solutions that are included within the vendor
certification process. This item will be highlighted in the next section and may become a
pivotal element in the overall generic cabling design for the intelligent building.
The common cabling media used today are Unshielded or Shielded Twisted Pair (Copper)
and Multimode and Singlemode Optical Fibre cables.
Building Management Systems
Centralised control systems deliver functionality and depend on user connectivity through
the horizontal and backbone sub systems to one location where all equipment is
centralised. These systems were developed with product specialists and technology
experts in mind and were far from user friendly to the building owner or tenant. They
required highly skilled operators to gain the product efficiencies and functionality specified
by these manufacturers.

With the building owner and tenant demanding high speed, high capacity information
processing, increased functionality from the product and increased focus on reliability and
disaster recovery, we have seen the move in the early 80’s to distributed processing
environments. A distributed control system spreads its active devices and intelligence
throughout the facility.
Cabling designers need to be aware of the differences between these systems.
Today, with the move to internationally driven Open Standard (Seven-Layer Network
model) by the International Standards Organisation (ISO) as represented by the Open
Systems Forum (OSF), has seen the move toward interoperability onto today’s minimum
network standard, 10Mbps Ethernet.

The main service applications that make up an integrated building management system
includes:
• Climate Control or HVAC
• Lighting Control
• Public Address System
• Security/Access Control
• Video Services
• Intercom Systems:
Planning Considerations
STEP-1 Identify locations of all of the Telecommunications and Control Devices
including their associated end devices
• Voice and Data outlets
• LAN and Telephone devices include: PABX, Handsets, Hubs, and Routers
• Control Devices
• End devices
This information will assist in determining the quantity of Floor Distributors and other
cabling infrastructure required to design the final cabling solution.
STEP-2 Determine the best location for Floor Distributors and Building
Distributors and develop backbone and horizontal cabling distribution design
This activity will impact the overall cost of cabling and cabling support infrastructure
requiring both labour and materials.
STEP-3 Determine Cable Medium requirements.
The cabling medium considered as standard for voice and data applications include:
• 62.5/125 multi-mode Fibre cable
• 50/125 multi-mode Fibre cable
• 62.5/125 Single Mode Fibre Cable
• enhanced Category 5 multi pair copper cable
STEP-4 Installation
A KRONE endorsed/certified installer would then proceed to install the cabling
requirements. Regular discussions with the Service Application Provider and site co-
ordinator will ensure correct location of cables with cable pair terminations on allocated
modules and connection boxes.
STEP-5 Cabling Commissioning and certification
• Assign pairs
• Jumpering

Structured Cabling System
Telecommunications can carry all low voltage signal systems that control information within
the intelligent Building and modern structured cabling systems, such as the KRONE
PremisNET C
3
Solution, have been designed to and can Control, Command,
Communicate, and consolidate all these individual building systems over one
infrastructure.
The KRONE PremisNET C
3
Solution uses multiple Floor Distributors strategically placed
onto each floor to capture all Building Management (BMS) System Service Applications.
The KRONE PremisNET C
3
Solution has adopted a tiered hierarchy structure to simplify
the understanding of the cabling hierarchy. The cabling requirements for these systems
will in general be divided into three tiers of cabling. We will call these:
TIER 1: Management Systems Connectivity (Application Services)
TIER 2: Distributed Architecture Intelligent Device Connectivity (Backbone Services)
TIER 3: Sensor or End Device Connectivity (Horizontal Services)
