Purpose
This unit standard is for cablers working in the telecommunications customer
access network, which generally extends from an exchange switch to the
point of entry at customers’ premises.
People credited with this unit standard are able to:
– identify customer access networks, services, and components;
– identify cable characteristics and coding;
– outline cable installation practices;
– outline concepts of building frames, cabinets and enclosures, and service
entrance and termination practices;
– interpret cable plans used in the customer access network;
– outline testing of copper, coaxial, and fibre cables; and
– joint and terminate lead-in cable.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
