In contrast to the level 3 Unit 17485, Install and maintain basic telecommunications
outside plant and equipment, where trainees primarily work with, and have
responsibility for, the items of plant 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.
