Qualification -
Unit of Competency ICTCBL2137B - Install, maintain and modify customer premises communications cabling: ACMA Open Rule
Description This unit describes the performance outcomes, skills and knowledge required to safely install, maintain and modify customer premises communications cabling required according to the Australian Communications and Media Authority's (ACMA) ‘Open’ Cabling Provider Rule.This rule is associated with small installations connected to sockets and larger commercial and industrial installations involving many lines, multi-pair cables, backbone cabling, multi-story buildings and more complicated termination modules and distributors.The cabling activity may be a new cable installation or an upgrade of cable capacity for an existing network or subsystem, or cabling infrastructure for convergence to Next Generation Networks (NGN).Convergence in the telecommunications and IT areas is the emergence of a single infrastructure for a range of telephony and IT services. Telephone, voice over internet protocol (VoIP), internet protocol TV (IPTV) and computer data may all travel over a single metallic customer cable, optical fibre cable or wireless link in a specific location.Assessment by a TITAB-registered assessor is recommended.This unit meets the minimum ACMA prescribed level of knowledge and skill that safeguards matters of health, safety and network integrity, and addresses matters of interoperability where customer equipment and standard telephone service are involved only.Note:Completion of this unit does not imply industry competency using specialised cabling, such as coaxial, optical fibre and structured cablingCompletion of the following six cabling units: ICTCBL2005B , ICTCBL2006B , ICTCBL2008B , ICTCBL2012B , ICTCBL2017B and ICTCMP2022B exceed the requirements of this standard and fulfil the requirements for ACMA Cabling Provider Rules: Open Cabling Category for Cabler RegistrationTo be permitted to work with lift cabling, cablers are required to have completed the relevant Electrotechnology qualification, such as the Certificate III in Electrotechnology Electrician or equivalent.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit applies to customer cabling terminated on distributors. It applies to installation, maintenance and modification of indoor, external, underground cabling on private and public property.Customer cabling, for the purpose of this standard, may be used to connect devices for a range of applications, including telecommunications, Ethernet, video and multimedia, security and alarms, and fire protection.The cabling task may be a new cable installation or upgrade of cable capacity for an existing network or subsystem for convergence to NGN applications.Cabling installers providing services in telephony, VoIP, IPTV and computer data over a single metallic customer cable or optical fibre cable in a specific customer location apply the skills and knowledge in this unit.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
