Other Telephone / Data Cabling
Requirements
• Cables from a wall outlet to a network interface
(e.g., computer or printer) should be a maximum of 3 metres.
• A minimum of two outlets at each location.
• The recommended jumper/patch cord length is 7 metres.
• A maximum of 2 patch cords per horizontal run.
• To reduce untwisting of cable pairs, strip back only as
much cable jacket as required.
• The untwisting of a pair should not be greater than 13mm
for Category 5 cable.
• Maintain proper bend radii.
• Allow additional cable at each end for re-termination.
• Any additional cable should have a fixed path, i.e. if a
cable loop is left, ensure it is secured.
Testing
All Category 5 cables should be checked for continuity and
for correct pair termination.
The Clipsal 5ABLTC tester provides instant identification of
the most common voice and data cabling problems including
short circuits, open circuits, reversals, and incorrect polarity.
Further testing with specialised equipment will be required to
verify the installation meets a specific category rating.
Mode 3/5 Wiring
Mode 3 and Mode 5 are specific wiring configurations for
various telephone devices such as security systems and
modems. This configuration allows the telephone device to
gain priority of the line by disconnecting every device wired
after the mode connection.The Mode 3 configuration
disconnects both wires of the telephone line, Mode 5 will
only disconnect one.
REN - Ring Equivalence Number
The REN relates to a specific device impedance on the
telephone line. The maximum number of telephones or other
customer equipment, connected to a single exchange line at
one time is based on the total REN of all devices.
If there are too many devices connected to the line, it is
possible that no telephone will ring. According to the ACA
TS003. The Carrier is only required to support an REN of
three. (All Austel approved telephone equipment since 1990
identifies its REN).This would mean that the line can
support three telephones with a REN of 1 each.
Licensing
All cabling with the possibility of being connected either
directly or indirectly to the PSTN (Public Switched Telephone
Network) is required to be installed according to the appropriate
standards by a licensed cabler.
