PURPOSE OF THE UNIT STANDARD |
The aim of this unit standard is to provide an introduction to, and an understanding of, the architecture and major design issues relating to switching systems. It also covers the physical aspects of switched network connectivity and aims to develop an appreciation of associated configuration equipment.
Learners studying this unit standard will be able to appreciate the need for switching systems in a current network and the features which are a standard customer requirement. The need now is for networks to be seamless and transparent from the user as they span the globe and there is a shift towards unified networks incorporating different technologies in a multi-media environment. This unit standard will contribute to the full development of any learner within the telecommunications environment at NQF Levels 4, 5, and 6. A person credited with this unit standard will be able to: This unit standard will contribute to the full development of the learner within the telecommunications environment by providing recognition, further mobility and transportability. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the telecommunications environment. |
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING |
