Special notes
1
This unit standard has been developed for learning and assessment in the
workplace.
2
The term building and data cabling systems refers to telecommunications cabling
systems in buildings, and includes the more complex systems and testing
techniques.
3
In contrast to the level 3 Unit 17486, Install and maintain basic telecommunications
building and data cabling, where trainees primarily work with, and have responsibility
for, the 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 endto-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.
