Telephone/Data Cabling
Requirements
Only cabling for services required today will result in an
inflexible system for tomorrow. Cabling for a range of future
possibilities will provide the flexibility to be able to change
the services without the need to recable later.
All telephone and data cabling should be Category 5 or higher,
with Category 5e recommended.
The category rating of the cable used is dependent on
correct installation practices.
When cabling with Category 5 cable, always adhere to the
appropriate standards and regulations.
Cable Support
Category 5 performance will only be achieved with adequate
cable support.
• Cables (regardless of type) must be supported i.e. they
must not sag or stretch under their own weight.
• Cables should not be pulled across suspended ceiling tiles
or across fluorescent luminaires.
• Cable should not be tied to ceiling grid work wires.
• Where necessary, use approved cable trays, conduit or
Category 5 “J Hooks”.
Cable Pulling
• Avoid tight bends, sharp edges, sharp corners, kinks and
turns.
• Make pulls as straight as possible.
• Do not drag cable around corners.
• Gradually pull cable into place.
• Pulling tension should not exceed the recommendation of
the manufacturer or 11kgs, which ever is lesser.
• Care should be taken to minimise cable twisting.
• Avoid unnecessary bends. During installation, keep the
bend radius as large as possible.
• The minimum bend radius is ten times the outside
diameter of the cable during installation.
Cable Runs
• Avoid high temperature areas as high temperatures
increase cable attenuation.
• Replace damaged cable.
• Apply cable ties loosely.
• Avoid sources of EMI.
• Run cable at least 150mm away from fluorescent luminaires.
• Never exceed 90° bends.
• Never over tighten cable ties.
• Never step on or run over cable.
• Never splice or use bridge taps.
• Never use staple guns.
• Never overstress the cable.
• The maximum horizontal run should be 90 metres from
termination point to wall socket.
Terminations
Category 5 cable runs and terminations on a modular RJ45
socket should be carried out in accordance with the relevant
communications and data standards. Each socket can be
used for either a data or telephone application. If the installation
and termination of data and telephone points are different,
the flexibility of the system will be diminished. All Category 5
terminations should be carried out to T568A Standards.
Cable categories refer to the bandwidth available on the
cable, the higher the category the greater the bandwidth.
* Category 1- voice * Category 2- up to 1 MHz * Category 3- up to 16 MHz
* Category 4- up to 20 MHz *Category 5- up to 100 MHz * Category 5e- up to 100 MHz
