System Design
Points To Remember
• All video distribution should use RG-6 Quad Shield cable,
even the short leads from the wall plate to the TVs.
• The total length for any RG-6 cable run should not exceed
the recommended lengths.
• All telephone and data should be cabled with Category 5
cable or greater. This higher grade cable isn’t required for
telephone service, however having both data and telephone
points cabled with Category 5 gives the flexibility to
interchange those services.
• No Category 5 cable runs should exceed 90 metres.
• The StarServe enclosure should be located such that
cable runs are minimised.
Determine the number of points
required (telephone / data / video)
The number of cables and outlets to be installed is a subjective
requirement of a StarServe system. It is primarily up to the
user to determine the level of infrastructure required for the
installation, with recommendations from the installer.
It is essential that the user is made aware of the varying
level of infrastructure that can be implemented. A balance
needs to be made between cost and flexibility. This can only
be done by a user who understands the long term benefits of
a structured wiring system.
Various standards make recommendations for minimum
cable infrastructure, from these the following guidelines are
suggested.
Grade Infrastructure 1 - 2 x Category 5 cables
1 x RG-6 Quad Shield cable
Grade Infrastructure 2 - 2 x Category 5 cables
2 x RG-6 Quad Shield cable
Grade Infrastructure 3 - 3 x Category 5 cables
2 x RG-6 Quad Shield cable
Plan The Installation
Before any cabling is done it is important to plan the entire
installation. Firstly, all required services need to be assessed:-
• How many incoming telephone lines.
• How many telephone points / Telephones.
• How many lines to each point.
• How many data points.
• How many television points.
• How many Modulators.
Once these requirements are established, future possibilities
can be determined. It is important to make future allowances
when determining the number distribution points required. This
will greatly determine the flexibility of the system and its
future benefits.
Emphasis On Future
Requirements
In residential buildings, the purpose in having a structured
cabling system is to allow for both current and future service
requirements.
Only cabling for the services required today will leave an
inflexible system for tomorrow. An installation should be
cabled for a range of future possibilities. This provides the
flexibility to be able to change the systems within a home,
without the need to recable.
