PREFACE
This Handbook, HB 29, is one of a series of Handbooks and Standards known
collectively as the Communications Cabling Manual (CCM). The CCM is
compiled by Standards Australia in consultation with the Committee CT-001,
Communications Cabling representing carriers, the Communications Alliance, the
Australian Communications and Media Authority (ACMA), cable manufacturers,
cablers and end-users. The original Handbook, HB 29—1998, was prepared and
illustrated by Peter Graham of Stowe Australia. This latest edition supersedes
HB 29—2000 and was reviewed and updated by members of Committee CT-001,
Communications Cabling, which is responsible for Australian/New Zealand
Communications Cabling Standards.
The CCM is designed to provide essential information to the communications
cabling industry and is available in five modules.
Module 1 Australian regulatory arrangements (HB 243)
Module 2 Communications cabling Handbook (HB 29)
Module 3 Residential cabling Handbook (HB 252)
Module 4 Regulatory Standards
(AS/ACIF S008:2006 and AS/ACIF S009:2006 or their
replacements)
Module 5 Voluntary Standards
(e.g. AS/NZS 3080 and AS/NZS ISO/IEC 24702)
The objective of this Handbook is to supplement the information in the two
Regulatory Standards derived from the Cabling Provider Rules (the Act) and the
Voluntary Standards associated with Commercial and Industrial generic cabling
systems installation, with explanatory material, practical details and generally
useful information in order to assist installers and others in the field. It includes
important extracts from the ‘Wiring Rules’, AS/ACIF S009:2006.
The word ‘must’ is used in this Handbook to indicate a requirement of the
applicable Standard or the Act.
Whilst the information contained in this Handbook is the latest available at the
time of printing, users need to consult the latest edition of any referenced
Standard, amendments to the Telecommunications Act and its regulations, and use

the references herein as a guide only.
This Third Edition is the result of a complete revision. Two of the major changes
are the re-writing of Section 6 Testing and Administration (Optical Fibre Cable) as
the result of the Australian adoption of ISO/IEC 14763-3, the international fibre
optic (FO) testing standard, and the inclusion of material dealing with industrial
cabling as per the recently published adoption AS/NZS ISO/IEC 24702,
Telecommunications installation—Generic cabling—Industrial premises.
This Handbook is updated regularly and feedback from users is welcomed to assist
in improving successive editions.
