Definitions
AM – amplitude modulation.
Complex or non-standard – three or more components and/or services used together
in radio or cellular networks or enterprise solutions systems.
Converging Technology – any existing technologies that are integrated to provide a
new service including convergence of any previously separately existing technologies
that now share resources.
DHCP – Dynamic Host Configuration Protocol.

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.
