Elements and Performance Criteria

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.
Alarm may include:
computer screen alarm information sourced from network management system
physical indicator lamps on:
equipment circuit cards
equipment rooms
racks
subracks
suites.
Network elements may include:
equipment utilised in the following networks:
cellular
data
fixed radio
hybrid fibre coaxial (HFC)
mobile radio
satellite
voice.
Impact may include:
customer impact:
degradation of service
disruption of service to residential customers
intermittent performance
loss of revenue to an enterprise customer
loss of service to an enterprise customer
network impact:
congestion
drop out
excessive latency
limited coverage
no transmission
poor grade of service
poor signal quality
routing problems.
NOC may include:
engineering unit within a carrier responsible for:
coordinating repairs or changes to the network
monitoring the network
performing diagnostic tests.
Relevant parties may include:
customer
design engineer
NOC
on site technical staff
other installations sharing same network traffic
project manager
specialist technical support staff.
Outage may include:
loss of service to customers due to a network fault or upgrade
planned, in the case of network upgrades or unplanned in relation to faults.
Methodical strategies may relate to:
analysing test results and previous fault history
conducting tests
coordinating the actions of upstream and downstream maintenance personnel
isolating fault progressively to eliminate probable causes
reloading software
remotely interrogating hardware
scheduling diagnosis for low traffic times
substituting hardware.
Escalation procedures may include:
greater involvement from the NOC
progressive shifting of network restoration responsibility to more capable areas.
Administrative tasks may include:
checking correct labelling of all equipment and amending where required
completing job orders and submitting to appropriate enterprise organisational unit
completing test sheets according to specification and logging test instrument usage
following quality control procedures
handing over installation briefs, documents and equipment manuals to operational staff
recording test results and updating appropriate databases
updating design specifications and returning to design area as required by enterprise requirements.
Quality assurance may include:
acting on logs, reports and other data to guide ongoing quality improvements
updating logs and reporting on installation or maintenance activities.

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 and analyse a range of network alarms including use of fault history and ranking of likely causes
undertake and monitor network repairs
plan and coordinate the actioning of network alarms.
Context of and specific resources for assessment
Assessment must ensure:
sites on which local and remote monitoring and analysis of network alarms may be conducted
manufacturer's technical 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 performing remote diagnosis of network alarms, ranging from common to complex
direct observation of the candidate preparing an action plan in response to a range of network alarms
oral or written questioning of required knowledge.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTTEN4081A Locate, diagnose and rectify faults
ICTTEN4086A Undertake routine maintenance of the telecommunications network
ICTTEN4087A Undertake remote diagnosis and repair of network faults.

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.
