Special notes
1
This unit standard has been developed for learning and assessment in the
workplace.
2
Telecommunications customer premises systems – the components that make up
telecommunications systems at customer premises, and includes the more complex
equipment and complete or end-to-end systems.
3
In contrast to the level 3 Unit 17489, Install and maintain basic telecommunications
customer premises equipment, where trainees primarily work with, and have
responsibility for, the individual items of cabling and equipment in their immediate
vicinity, and under direct supervision, this level 4 unit standard is concerned with the
ability to encompass larger, more complex entities or systems. For this unit standard,
the individual components may be separated by some distance; testing will include
system or end-to-end tests; the work is without direct supervision; there may be
supervision of others and responsibility for their work. Ability to work with this larger
focus is a critical aspect of assessment against this unit standard.
