What capabilities can turn your structured cabling system into a critical building asset; one that reduces
costs, simplifies application deployment, enhances the workplace experience, and maximizes the poten-
tial to qualify for all physical layer and audiovisual innovation technology credits proposed by BICSI’s
Green Building Technology Alliance?
Imagine these scenarios:
1. An employee enters a building with a badge – his work space is illuminated, network access is provided, HVAC adjustments
are made, and nighttime power conservation methods are disabled
2. A motion detector is tripped in a secure area – cameras zoom in on the location of the security breach, video feeds are
transmitted to multiple locations, audio communication is enabled, operation of classified applications is suspended, and SMS
text, e-mail, and IP phone announcements are forwarded to security personnel
3. A fire alarm is activated – emergency lighting and pathway guidance systems are activated, doors to exit paths are unlocked,
video and audio feeds are enabled, emergency shutdowns of critical systems are initiated, and status and containment
information is forwarded to rescue personnel
4. A training center requires new audio/video services – the upgrade is made by means of a modular RJ-45 style plug and jack
connection to the building’s structured zone cabling system and no new cabling needs to be deployed
5. New patient monitoring services must be added to hospital rooms with limited pathway space – 10/100BASE-T is deployed over
the unused pairs of a TERATM category 7A channel, no new cabling needs to be pulled, and less space is consumed by the
category 7A channel than by multiple category 5e channels

2. ConvergeIT™
The ANSI/TIA/EIA-8621 and ISO 164842 series building automation
systems standards raised the industry’s awareness of the capabilities of
structured cabling by specifying planning requirements for the support of
low-voltage, non-telecommunications applications, such as fire alarm,
security, audio/video (A/V), and energy management, using modular RJ-
45 style connectivity and twisted-pair cabling. Draft standards, such as
those under development by the IEEE 802.1 Audio Video Bridging (AVB)
task force, go even further by specifying protocols that ensure high
quality audio and video streaming over Ethernet. The advantages of AVB
technology include potentially lower equipment costs, ease-of-
installation, and the ability to network applications that traditionally
operated on widely varying and non-compatible platforms. As would be
expected, network equipment manufacturers, such as Broadcom, are
rushing to implement the IEEE 802.1 technology in their Ethernet
switches, end-point devices, physical layer devices (PHYs), and software.
In order to be a true building asset, today’s cabling systems must integrate
a wide range of emerging and future low-voltage building needs, while
ensuring optimum quality of service and minimal disruptions, in an
efficient and non-wasteful manner. ConvergeIT provides the following
secure, scaleable, and flexible benefits in the enterprise environment:

Planning
Due to the high variability in the
number and type of low-voltage
applications found in different
end-user environments, it may be
difficult to approximate the
number of cabling drops required
to support a ConvergeIT network.
For planning purposes, table 1
provides an approximation of the
coverage area provided by one
4-pair ConvergeIT channel
in a variety of environments.
Remember that these coverage

Classroom 25 Coverage area requirements may be centralized for security and access controls. Plan for the
unique low-voltage requirements for each area type (e.g. fire alarm safety system, access control,
and HVAC).
Data Center 25 Coverage area requirements may be centralized for security and access controls (e.g. security
cameras and sensors, access control, and HVAC)..
Hotel 25 Coverage area requirements may vary if low-voltage services have centralized control (e.g. HVAC,
fire alarm safety system, and access control).
Indoor Parking 50 Identify fire, security, carbon monoxide detection and HVAC requirements. Voice connections may be
required for security.
Manufacturing 50 Coverage area size may vary according to manufacturing processes, environment, and building
design (e.g. gas and temperature sensors, fire alarm safety system, access control, and ventilation).
Mechanical Room 5 Determine location of air handlers, chillers, boilers, pumps, fans, compressors, etc. Air handlers will
typically have a higher concentration of low-voltage devices.
Office 25 Coverage area sizes will typically be greater in an open office environment than in a dedicated office
space. Zone cabling is recommended for open office environments (see page 7).
Retail 25 Security requirements (e.g. CCTV, alarm, and access control) may increase the coverage area density
Cable Sharing
Many applications, such as security cameras, broadcast
video, and device control, only transmit over one or two pairs
of a 4-pair cable. When UTP or F/UTP copper media is
deployed to support these applications, multiple unused pairs
can contribute to excessive cable congestion, overfilled
pathways, and additional cost. This obstacle can be over-
come by utilizing the practice of cable sharing in conjunction
with TERA category 7A/class FA cabling. Because of its fully
shielded construction, the signals on individual category 7A
pairs are fully isolated from each other and multiple
applications transmitting on just one or two pairs may be run
over a TERA category 7A/class FA channel without concern
for interference. In fact, category 7A/class FA media is so
robust, that two PoE applications (12.95 W maximum power
delivered to the each powered device) can be supported over
one TERA channel as long as power is delivered using IEEE
802.3-2005 Alternative A!
In a typical ConvergeIT environment, a wide range of
applications such VoIP (voice over IP), CATV, CCTV,
Internet, security cameras, and intercom, which only utilize
one or two pairs for transmission, may be deployed.
Assuming that these exact six services are required for a
specific network implementation, providing a dedicated
4-pair cable for each low pair count application would require
6 outlets at the work area or zone box; leaving a total of 16 Figure 1:
unused pairs! A more efficient solution would be to Typical ConvergeIT Cable
implement a cable sharing approach whereby each work area Sharing Implementation
or zone box would support the 6 services over two TERA
category 7A/class FA channels. The recommended
configuration of the two TERA outlets is shown in Figure 1.

6. ConvergeIT™
Traditional Cabling Approach
A traditional or “home run” structured ConvergeIT cabling design consists of horizontal cable run from the horizontal
cross-connect in the telecommunications room (TR) directly to each equipment or work area outlet. If it is a requirement of
the low-voltage application (e.g. RS-232, RS-442, or RS-485 circuits), multipoint bus and ring cabling topologies are also
supported. A multipoint bus configuration allows multiple low-voltage devices to be attached to the same horizontal cabling
link (in this case, an endpoint termination or impedance matching device is typically used). As its name implies, a ring
configuration allows two separate horizontal cabling links to be connected between one or more low-voltage devices.
Maximum links lengths are limited to 90 meters (295 feet), independent of media, and the design shall comply with the
requirements ANSI/TIA-568-C.13 , ISO/IEC 118014 , and applicable building automation standards1,2. Figure 2. shows an
example traditional cabling topology where LAN cabling and security cameras are home run back to the TR and HVAC
device/controller, access control, fire alarm, and lighting control are supported in a multipoint bus configuration.
The benefits of a traditional ConvergeIT structured cabling design include:
- Ease of deployment in small offices and spaces
- Simple to label and administer
- Abandoned cable can be quickly identified

7. ConvergeIT™
Zone Cabling Approach
A zoned structured ConvergeIT cabling design consists of horizontal cables run from the horizontal cross-connect in the
telecommunications room (TR) to zone boxes serving as consolidation points (CPs). Zone boxes may be located in a raised
floor, in the ceiling (consideration should be given to plenum requirements), within furniture, or mounted on a wall. Cables are
then patched from the zone box to the equipment and work area outlets. As with traditional topologies, multipoint bus and ring
cabling configurations are supported if required by the application. Maximum link lengths and design requirements are also con-
sistent with traditional cabling topologies. Figure 3 shows an example zoned cabling topology where horizontal cables are run
from the TR to zone boxes and then patched to equipment/work area outlets supporting LAN, HVAC control, access
control, fire alarm, security cameras, and lighting control devices.
The benefits of a zoned ConvergeIT structured cabling design include:
- Ease of deployment in large office and open office spaces
- Facilitates the use of pre-terminated trunking cables for expedited installation
- More efficient pathway utilization
- Ease of adding new services and upgrading to IP-addressable devices
- MAC work costs less and is faster and less disruptive since the cabling from the CP to the TR remains unchanged
(cabling is reconfigured from the CP to the work area only; enabling rapid reorganization of floor space).

Zone Box Location:
When deploying a zoned cabling solution, zone boxes should
be logically distributed in an open coverage area and should
be limited to serving a maximum of 12 equipment or work area
outlets. Zone boxes shall be located in fully-accessible, fixed
locations such as permanent walls and building columns and Zone Box
shall not be located in obstructed areas. Zone boxes shall not Coverage

locating wireless access points in ceiling spaces that can be
applied to zone box positioning. This approach supports all
ConvergeIT applications and may be especially convenient for
the management of installations where cable sharing is used
to support multiple applications operating over TERA category
7A/class FA channels. A pattern of circles or grids with an
associated coverage area radius can be defined, as shown in
Figure 4, with the intention that equipment and work area Wall
outlets should be centrally located in their coverage area and
zone boxes should be centrally located in their associated
coverage area grid. Although the coverage area radius may Figure 4:
range in size from 3 meters to 30 meters, a coverage area Example of Distributed Zone Box Locations

Low-Voltage Considerations
Characteristics of Low-Voltage Applications Suitable for Operation over Twisted-Pair Cabling
The maximum current capacity and operating voltage of low-voltage applications supported by ConvergeIT
cabling are defined in the ANSI/TIA/EIA-8621 and ISO 164842 series building automation systems standards.
A summary of the specified maximum operating conditions is provided in table 2. While there are limited π
provisions in these Standards for operation in wet (but, not immersed) environments, ConvergeIT cabling is
suitable for installation in dry environments only. Additional information on the current carrying capacity of
bundled cables, including guidance for minimizing temperature rise using higher category and screened and
shielded cabling, is described in TIA TSB-1848 , the soon-to-be-published ISO/IEC 291259 , and Siemon’s white
paper entitled, “IEEE 802.3at PoE Plus Operating Efficiency: How to Keep a Hot Application Running Cool” 10.
