This unit standard covers knowledge for people engaged in
installation and maintenance of complex or non-standard
applications in the provisioning and restoration of
telecommunications core networks (fixed and mobile networks).
People credited with this unit standard are able to demonstrate
knowledge of:
–
factors that can degrade performance and stability of core
networks, and ways to reduce the impact of these factors;
and
–
current network and element management and
performance monitoring systems for core networks.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR 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.
