Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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.

Required Skills and Knowledge

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

Range Statement

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.
