Qualification -
Unit of Competency ICTOPN6125A - Manage dense wavelength division multiplexing transmission system
Description This unit describes the performance outcomes, skills and knowledge required to manage a dense wavelength division multiplexing (DWDM) transmission system using graphical user interface (GUI) management software.Network management software provides a single point of access to the fault, performance, security and administrative functions of network management. Alarms are displayed and performance data and statistics are visible, allowing network degradation to be detected before actual failure occurs.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application Technical staff in telecommunications who work with DWDM optical transmission systems where network management is implemented apply the skills and knowledge in this unit. The network management operations are often carried out at a central Network Operations Centre (NOC).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

  • Analyse performance monitoring data and alarm data
  • Prepare a report and make recommendations based on the analysis
  • Report on network degradation over a period of time
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

monitor the network for faults and performance and produce a fault and performance report

analyse performance monitoring and alarm data and prepare a report with recommendations based on this analysis.

Context of and specific resources for assessment

Assessment must ensure:

access to sites on which DWDM equipment and associated network management can be operated

access to DWDM system and test equipment currently used in industry

access to relevant equipment manuals, software manuals and other procedural documentation.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct observation of the candidate using transmission system manuals and specifications to manage the network and analyse test results

evaluation of measurement results and reports produced by the candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTOPN5121A Test and commission a dense wavelength division multiplexing transmission system

ICTOPN6124A Manage optical ethernet transmission

ICTOPN6128A Design a dense wavelength division multiplexing system.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

analytical skills to identify and rectify faults in DWDM transmission system

communication skills to:

liaise with internal and external personnel on technical and operational matters

relate to work associates, supervisors, team members and clients

information technology skills particularly interoperability between management systems

literacy skills to:

interpret technical documentation, such as equipment manuals, specifications and service orders

write reports using standard formats

problem solving skills to resolve software inoperability problems

research skills to gather data, observe and analyse transmission issues

technical skills to operate test equipment

Required knowledge

familiarity with workplace and industry environment

optical communications principles

DWDM technology

simple network management protocol (SNMP)

organisational policy and procedures

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Networking issues may include:

access

administration

protocols:

SNMP

security

transaction language 1 (TL1).

Appropriate person may include:

network administrator

network planner

project manager.

Network topology may include:

background maps

communications links between network elements or groups

groups of elements

nested groups of elements

physical shapes.

Manage the network may include:

acknowledging or clearing alarms

determining alarm severity

determining overall network status

integrated with external management system

locally

managing connections

managing protection

monitoring the network for faults

monitoring the performance of network elements

performing software download and upgrade

producing equipment inventory at a given site

remotely

stand alone management

viewing historical event logs and alarm data

viewing performance parameters and thresholds

viewing real time active alarm data.

Network degradation may include:

decreasing received optical power level

decreasing transmit optical power level.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
