Wiring Panels vary in size; plan on a wall area of no less than
4’ high by 4’ wide for the Panel and Cables in a service
area such as a garage, attic, or basement. The Structured Wiring
method of distribution is best suited to new construction when the
walls are still “open”, however it is still a viable
solution for an existing home that offers access to the desired
rooms via an attic or basement.

Distribution device contains all the hardware components to support
all analog and digital networks.
coax distribution equipment may include internal cable support from
one or more outlets to allow in-home source signals such as the
output of a DVD player or VCR to be viewed at any cable outlet.
These signals are combined with incoming cable or off-air signals
so that they can be viewed on the same destination equipment.
cables are home-run from the distribution equipment to the outlet
jack. Outlets may contain almost any combination of TP voice or
data jacks, or coax cable jacks.
Infrastructure wiring systems need to provide support for a range
of applications that use TP wiring and coaxial cable wiring. The
following is a list of the most common requirements for each media
TP voice telecom applications
Voice telephone outlets (voice, fax, analog modem) in most rooms
of the home
Support up to 4 incoming lines
Allow each outlet to be assigned a combination of incoming line
TP data network applications
Support Ethernet type data networks at outlets in most rooms
Support data rates of at least 100 Mbps
Attach to a network hub device at the distribution device
Traditional coax cable applications
Distribute incoming cable television service to multiple locations
in the home
Distribute off-air television service to multiple locations
Provide necessary signal amplification and conditioning
Support necessary termination at each outlet
Advanced coax cable applications
Distribute in-home generated video sources to the same outlet as
cable TV service
Provide DSS signal distribution
Support reverse cable signal path
Support cable modem service
available distribution systems are designed to support a minimum
subset of these capabilities (traditional services) as well as data
and advanced coax services.
Branch cables for each network type (TP, coax, FO) originate at
the distribution device and terminate at a single wall outlet. This
type of cable run, where there is one cable from an outlet back
to the distribution device, is referred to as a home-run wiring.
A home-run means that there is only one connection point, or outlet
jack, on each branch cable.
methods, particularly for telephone wiring, allowed several outlets
to be connected to one cable. This is referred to as daisy-chain
wiring and is no longer used for several reasons.
allows maximum flexibility in determining the application that is
supported at the outlet. An outlet that is used for voice service
today can be easily changed to data service just by moving the cable
at the distribution device. It also allows high-speed data service
to be supported since that service permits only one device attached
to a cable run.
TIA-570A requires a minimum of one outlet location (for each media)
in each of the following rooms: kitchen, each bedroom, family/great
room, den/study. In addition the standard states that outlet locations
should be provided in each room and additional outlet locations
provided within unbroken wall spaces of 12 ft. or more. Additional
outlet locations should be provided so that no point along the floor
line in any wall space is more than 25 ft. from an outlet location
in that spaces.
The distribution device is typically installed in a metal rough-in
box mounted during the home prewire stage. All branch run cables
(voice, data, coax, etc.) start at the distribution device box and
run to outlet locations throughout the home.
device (or center) houses TP distribution equipment, coax network
distribution equipment, a power supply, and depending on the manufacturer,
devices such as Ethernet hubs, modulators, even audio distribution

Typical distribution center equipment (right) contains coax cable
distibution on left and TP cable distribution on the right side.
The TP network consist of the cable, outlets, and distribution equipment
necessary to support all analog and digital application that are
intended to be carried over TP cable.
TP cable used for infrastructure cabling should always be category
5, 4-pair, cable or better (category 5e). The category ratings of
cable was describes in Section 2. Category 5 cable (abbreviated
as CAT 5) is designed to support applications that use bandwidths
that need up to 100 MHz.
Standard pair color coding for 4-pair TP
cable per TIA standards.
The jacket of TP cable is available in several different colors
to help identify the use of cables in a particular installation.
There is no standard that defines a given color for a given application
(blue jacket for data applications, for example).
Plugs and Jacks
TP cable should always be terminated (connectorized) with 8-pin
modular jacks and plugs. Their design is standardized and almost
all are interchangeable between manufacturers
8-pin modular TP plug and jack.
outlets should always use modular 8-pin jacks. The wiring of the
four pairs in a TP cable to the pins on the jack is standardized
in TIA-570A as the T568A configuration. This refers to a standard
jack wiring in TIA-568A known as the 'A' configuration (no relation
to the letter A in the standard name). This wiring configuration
is shown in figure 3.6. There is another popular configuration known
as T568B that is used mainly in commercial installation. Most jacks
are labeled as to the color is assigned to what punch-down contact.
8-pin modular jack wiring. Jack pins are
numbered looking into the jack from left to right.
wiring configuration allows backward compatibility with traditional
4 and 6-pin jacks. Voice line 1 is always on the center two pins,
and voice line 2 is always on the next pair straddling line 1. If
a 4 or 6-pin plug is inserted into an 8-pin jack, the voice line
pairs (center 4) make correct contact.
Network Distribution Equipment
The TP network consists of branch runs of TP cable originating at
the TP distribution equipment and terminating in a TP outlet (Figure
3.7). The two primary uses of TP are for traditional voice and analog
services and data networks. The TP distribution device must receive
incoming telecom services from the telephone NI and connect them
to branch cable runs to outlets that are used for voice and other
analog services (fax, modem, etc.). It must also support data networks,
typically Ethernet, from a hub device.
Typical TP network wiring from distribution
location to outlet locations in each room.
The TP cross-connect is used to support distribution of incoming
telephone analog services. It provides a flexible way to select
which incoming telecom lines from the NI, go to which outlet lines
by cross-connecting incoming pairs to outlet pairs, either in groups,
or on a one-to-one basis. This allows jacks in the home office,
for example, to have the office telephone line appear on the line-1
pins of jacks in the office, and the kids telephone line to appear
on line-1 of the jacks in the kids room, and so on. This prevents
having to use adapters on the outlets.

the four possible incoming pairs from the NI at the Auxiliary Disconnect
8-pin jack (four pair CAT 5 cable is run from the Auxiliary disconnect
to the telephone NI). The other jacks represent locations to connect
branch cable runs to room outlets.

2, 3, and 4 connected to line 1, 2, 3, and 4 at the outlet respectively
(called a "straight-through" cross connect). The top row
has incoming line-1 connected to outlet jack line-2, incoming line-2
connected to outlet jack line-3, etc.

telco lines at the auxiliary disconnect are cross connected in three
groups of 4 jacks. Each group of jacks is intended to be connected
to branch cable runs (connectorized with a plug on the end) that
need the appropriate cross-connect for that room.
Ethernet data hubs for 10Base-T and 100Base-T are available (usually
standard) for almost all commercially available distribution devices
for TP cable. The hubs have 8-pin modular jacks for each cable run
assigned to a data outlet. They are available in 4, 6, 8, or more
3.10 shows how the hub is used to form a data network in the home.
CAT 5 cable that runs to any 8-pin modular outlet may be plugged
into the hub. The use and wiring is the same for 10 or 100 Mbps
networks as long as the 90 meter length limit is adhered to.
hubs are often built into gateway devices that interface to ADSL
or cable modems also installed in the distribution center.

to data outlets. Note that any outlet can be assigned as a data
just by plugging the cable from the outlet into the hub.
The coax network consists of branch runs of coax cable originating
at the coax distribution equipment and terminating at a coax outlet.
The primary function of the coax network is to distribute external
off-air or cable television service to outlets throughout the home.
The network also has several secondary functions including distributing
in-home generated video and RF sources such as VCR's and DVDs, and
supporting digital cable modem services.

to coax outlets in each room
network wiring from distribution device to room outlets.
As described in Section 2 of the Guide, the coaxial cable used for
in-home wiring should be RG-6 or equivalent. RG-6 is a general designation
(also referred to as Series 6) of a 75 ohm impedance high performance
coax cable. There are many different types of RG-6 coaxial cable
available from many different manufacturers. The biggest difference
between them is the number of shields.
of tri-shield RG-6 coax (foil, braid, foil). The center conductor
is always solid copper or copper-clad steel.
is available with 2, 3, and 4 shields. The inner shield is an aluminum
foil, covered by a woven braid. Tri-shield cable has another foil
shield, and quad-shield cable has a final outer braid shield. The
shield's primary purpose is to prevent external signals from getting
into the cable. The more shields, the better the interference protection.
However, most of the protection is provided by the foil shields,
the braids primarily provide strength and secondary shielding. Either
tri or quad-shield RG-6 is recommended for residential installation.
All coaxial cables used for residential broadband distribution are
terminated at each end in a coax 'F' connector.
outlet combining 2 coax jacks (INTERNAL and EXTERNAL) and 1 TP jack.
Mounting hardware is
available to allow CO-locating the jack outlet with the electrical
outlet making a neat installation.
order to support the distribution of signals that originate in the
home, two coax cables are often run to a coax outlet locations.
The modulated output of a VCR or other video source (modulated to
an unused cable or off-air channel), is attached to the INTERNAL
cable jack (Figure 3-16). The signal is then combined at the distribution
device with any other in-home sources at other outlets, amplified
(to overcome loss in the combiner and cable), and combined with
external sources (cable television or off-air signals), and distributed
to all EXTERNAL cables and jacks. This allows, for example, a VCR
in the den to be watched in the upstairs master bedroom.
design and installation of infrastructure cabling systems consists
of seven steps:
Define the job
with the client
Mark up plans
Develop wiring schedule
Mark locations on site
Prewire and test
Trim out and test
Documentation and familiarization
1. Define the job with the client
This consists of explaining the concepts and benefits and covering
the capabilities of the system. We will need to determine what the
needs of the client are, what equipment will be installed in the
home, the kinds of systems that need to be supported, and future
plans of the homeowner in terms of added system.
We use standardized technique, mark the location of outlets and
distribution equipment while consulting with the homeowner. Suggest
additional locations for outlets where computer equipment will be
located, appliances and entertainment equipment that may need Internet
access in the future. Also consider furniture arrangement and the
flexibility that extra outlets provide.
most desirable location for the distribution equipment. It should
be centrally located to keep wire length to a minimum. It should
also be in a conditioned space, typical limits are between 40 to
90 degrees F.
a cable schedule
A cable schedule contains a list of each cable required for the
prewire as well as outlet rough-in types. The format is not important
but it should contain:
the wire type
the associated outlet type
any special instructions (such as mount rough-in next to electrical
and check-off columns to record the results of cable testing
The cable schedule is used by the installer as a checklist to document
that each cable was installed, tested, and the correct rough-in
box was used.
locations on site
We Perform a walk through of the home to confirm the placement of
outlets and distribution equipment and mark the locations on wall
studs or the floor. Small tags stapled to the studs can be a helpful
way to code locations to the plans or wire schedule.
During the prewire stage, We will:
distribution equipment rough-in boxes
install the outlet rough-in rings or boxes at the marked locations
prepare the cable runs (drill necessary holes)
pull all cables from their source to destination locations and secure
label and test each cable
protect the cables and rough-in boxes until trim-out stage
Most distribution equipment will require a dedicated 15A outlet
or junction box. Coordinate with the electrical contractor to make
sure this branch cable is run from the load center during prewire.
The outlet rough-in
can be a ring or box mounted at a standard height above the floor.
Outlet height should be consistent with existing electrical outlets
and switches. If there are no existing outlets in a room, center
outlet boxes 12" from the floor, and other rough-in boxes 48"
from the floor for switch height.
the cable runs
We Keep infrastructure wire runs away from electrical wire runs
to avoid possible interference. We Do not use holes
used for electrical wiring or plumbing.
holes, We use the smallest hole necessary to allow a loose cable
We keep holes
centered in vertical studs. Never drill holes in glue-lam beams
or door or window headers. We consult local building codes on maximum
hole sized for various sizes of wood members.
Once the house is completed, the trim-out phase can be performed.
This consists of 6 steps:
1) Install the
outlets - install all outlet hardware and make sure outlets are
2) Install peripheral devices - such as keypads, modulators, etc.
3) Install distribution center equipment - install TP cross-connect
and coax distribution equipment.
4) Configure the system - configure outlet cable runs to the right
device, We make sure coax cable runs are
connected to the correct coax distribution equipment
5) Connect external services - connect cable runs from the NI devices
to the TP and coax equipment.
6) We test the system for proper operation - make sure all outlets
are operating properly
We collect all documentation associated with the job. Keep one copy
on the site and one at our office.
It is our responsibility
to complete familiarize the home owner well enough so that they
may take maximum use of the features with minimum difficulty. Cover
the documentation, manuals, system operation, warranty coverage,
and options that may be of interest in the future. We offer to have
someone personally train the user step-by-step and more importantly,
observe the user's knowledge and competency while using the system.
