Description
This unit describes the skills and knowledge required to assess roles and evaluate benefits of competing core network architectures. Core networks use convergent internet protocol (IP) based technologies with conventional technologies.It applies to individuals with a range of telecommunications skills and extensive knowledge of core and access network capabilities of the service provider, and prepares them for entry level planning and design for network additions and implementations to accommodate network growth and new technologies within the industry. No licensing, legislative or certification requirements apply to this unit at the time of publication.
