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.

2.75G EGPRS
3G and associated 3GPRS
4G.
Disturbances may relate to:
common channel signalling unit
link performance or sub-elements:
charging unit (CHU)
statistical unit (STU).
Reset sub-element may include:
hardware
software.
Adjust alarm thresholds may relate to:
increasing or decreasing thresholds for:
links between carriers
links between elements
subsystem units.
Cell performance may include:

bit error rate (BER) of air interface

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:
measure cell performance
measure output power received at around a cell
produce an alarm list and use this to locate faults
run diagnostic tests on sub-elements and subsystems
locate and repair faulty sub-elements and subsystems.
Context of and specific resources for assessment
Assessment must ensure:
site for mobile phone network tests and measurements
performance testing software
relevant legislation and documentation to test and repair network equipment.
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 performing measurements and repairing faults
review of fault details, rectification summary and recommendations prepared by the candidate
oral or written questioning to assess required knowledge.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTTEN3056A Install telecommunications network equipment
ICTTEN3089A Repair and replace telecommunications network hardware.

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.
