Application
This unit describes the skills and knowledge required to manage a dense wavelength division multiplexing (DWDM) transmission system using graphical user interface (GUI) management software.
It applies to individuals who use high-level technical skills and network management software to manage network operations. It is often carried out at a central Network Operations Centre (NOC).
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Element | Performance Criteria |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare to manage transmission system | 1.1 Determine networking issues and requirements from appropriate person 1.2 Install network management software according to vendor instructions, including access, security and administration 1.3 Create a customised representation of the enterprise’s network topology 1.4 Set and configure thresholds for performance monitoring 1.5 Prepare a plan to integrate the DWDM management system into a broader network management system where applicable |
2. Manage transmission system | 2.1 Manage network using appropriate communications links 2.2 Monitor network for faults and performance and produce a fault and performance report |
3. Use network management to report on the overall state of transmission system | 3.1 Analyse performance monitoring data and alarm data 3.2 Prepare report and make recommendations based on analysis 3.3 Report on network degradation over a period of time |
Evidence of Performance
Evidence of ability to:
determine network parameters and set up performance monitoring
manage network using appropriate software and tools
monitor network for faults and performance
produce fault and performance report
analyse performance monitoring and alarm data
prepare report with recommendations based on analysis.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
discuss workplace and industry environment relevant to dense wavelength division multiplexing (DWDM)
outline optical communications principles
explain DWDM technology, its operation and testing principles
summarise simple network management protocol (SNMP)
explain organisational policies and procedures relevant to the DWDM
determine appropriate report formats and communications tools required to make recommendations on performance and network degradation.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the Telecommunications – Optical Networks field of work and include access to:
DWDM system and test equipment currently used in industry
relevant equipment manuals, software manuals and other procedural documentation.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
