Application
Technical staff who prepare design drawings and specifications for a telecommunications installation apply the skills and knowledge in this unit.
This unit applies to access, building and core network installations within the carrier network. It may be applied to carrier, commercial and industrial installations. Communications applications include digital and analog, telephony, data, video, digital broadcasting, computer networks, local area networks (LAN), wide area networks (WAN) and multimedia.
This unit is one in a sequence of units that cover network design activities, including:
design drawings and specifications
designing a dense wavelength division multiplexing (DWDM) system
designing infrastructure
estimating and quoting
site survey.

Elements and Performance Criteria
1. Gather information on existing and proposed installation | 1.1 Inspect site to confirm plans where possible 1.2 Review existing plans, drawings and databases against the design brief |
2. Determine installation options | 2.1 Identify installation options from the design brief and the customer 2.2 Assess installation options against customer requirements and requirements of relevant legislation, codes, regulations and standards 2.3 Establish and assess the cost of options against customer's budget 2.4 Select most suitable option based on function, cost, standards and customer deployment rules |
3. Prepare and supply drawings and specifications | 3.1 Prepare clear and accurate installation drawings indicating proposed facilities and services 3.2 Prepare detailed design specifications for the network installation that include scheduled and non-scheduled codes to facilitate costing 3.3 Provide drawings and specifications to relevant parties and file copies for later reference according to company policies |
4. Verify specifications with customer | 4.1 Verify prepared documentation with customer 4.2 Obtain authorisation and approval from customer to proceed according to company policy 4.3 Issue design to the field with authority to construct |

Evidence Required
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: determine installation options produce schematics and plan drawings access database and knowledge systems for network information produce design drawings and specifications verify specifications with customer. |
Context of and specific resources for assessment | Assessment must ensure: sites where network installation may be conducted use of equipment currently used in industry relevant regulations, company policies and cabling specifications that impact on network installation activities. |
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: review of a design project completed by the candidate oral or written questioning to assess knowledge of design options direct observation of the candidate assessing design requirements review of design drawings and specification for a network installation prepared by the candidate. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended. 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. |
