ICTCBL2137A - Install, maintain and modify customer premises communications cabling: ACMA Open RuleICTCBL2137AInstall, maintain and modify customer premises communications cabling: ACMA Open Rule

Unit descriptor

This unit describes the performance outcomes, skills and knowledge required to safely install, maintain and modify customer premises communications cabling required according to 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 industry 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 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, 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 cabling.

Completion of the following 6 cabling units: ICTCBL2005A, ICTCBL2006A, ICTCBL2008A, ICTCBL2012A, ICTCBL2017A and ICTCMP2022A exceed the requirements of this standard and fulfil the requirements for ACMA Cabling Provider Rules: Open Cabling Category for Cabler Registration

To 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.

Application of the unit

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.

Employability skills

This unit contains employability skills.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

EVIDENCE GUIDE

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

terminate systems at both distributor and outlet locations

install and terminate one jumperable distributor (campus distributor or building distributor) with a capacity of 100 pair or greater

terminate one non-jumperable distributor (LD) and a patch panel

terminate at least one 50 pair, one 4 pair and one Ethernet cables including accurate completion of installation records, drawing alterations and compliance forms

place cables on support structures and building faces for both internal and external locations

secure methods for the above locations

demonstrate work practices which avoid cable damage

install the three common types of earthing system used in customer premises for cabling systems

read and interpret drawings related to cable layouts, outlet location, cable coding system, and identifiers and distributor locations

conduct and interpreting cable test results

interpret and apply relevant legislation, codes, regulations and standards

comply with all OHS requirements and work practices.

Context of, and specific resources for assessment

Assessment must ensure:

a site on which communications cabling activities may be carried out

use of cabling and field equipment currently used in industry

licensing requirements and other site related documentation.

Methods of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct observation of the candidate terminating:

systems at both distributor and outlet locations

one jumperable distributor (campus distributor or building distributor) with a capacity of 100 pair or greater

one non-jumperable distributor (LD) and a patch panel

at least one 50 pair, one 4 pair and one Ethernet cables

review of completed documentation prepared by the candidate, including accurate completion of installation records, drawing alterations and compliance forms

oral or written questioning to assess required knowledge.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTCBL2138A Install, maintain and modify customer premises communications cabling: ACMA Lift Rule.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
