This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard will contribute to the full development of any learner within the Telecommunications environment, more specifically within Transmission backbone environment by providing recognition, further mobility and transportability within the field. This skill forms the basis for the performance of duties in the day to day operations of Plesiochronous Digital Hierarchy and Synchronous Digital Hierarchy transport networks in specific occupations at NQF Levels 4, 5 and 6.

The knowledge, skills and understanding demonstrated in this unit standard are essential for upliftment, social and economic transformation in the Telecommunications environment.

The qualifying learner is capable of demonstrating:
  • An understanding of PDH and SDH principles and concepts.
  • An basic understanding of optical transport systems principles and concepts.
  • The ability to gain access to an SDH system's Operating Software.
  • The ability to identify and define components and functions/characteristics of the PDH/SDH systems.
  • The ability to use system related documentation.
  • The ability to manipulate physical components of the system.
  • The ability to perform operations on systems.

    The learning outcomes in this unit standard contribute to the exit level outcomes which provide qualifying learners with access to a range of further learning in this field at NQF Level 4 and above, in the form of workplace based learning programmes for occupationally focused qualifications. Qualifying learners also have an understanding of the science and technology which underpins these activities.

    N/A 

    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    Comment on this unit standard should reach SAQA no later than 26 October 2007.
    The level assigned to this unit standard is appropriate because the learner:
  • Has basic knowledge of some main areas of a discipline/field.
  • Has basic understanding of a discipline/field's key term, rules, concepts, principles and theories.
  • Is familiar with some of the essential methods, procedures and techniques of the discipline/field.
  • Has the ability to use the above to solve routine problems within given frameworks.
  • Has a basic information gathering, analysis and presentation skill.
  • Has the ability to communicate information reliably and accurately in the required medium of instruction.
  • Has the capacity to operate within clearly defined contexts, with limited scope for personal decision-making and responsibility.
  • Learn within a well-structured and managed environment.
  • Evaluate own performance against given criteria.

    Legal Requirements:

    Compliance to the following legal requirements and standards are mandatory:
  • Employer's Policies and Procedures.
  • Environmental Management System.
  • Independent Communications Authority of South Africa.
  • Occupational Health and Safety Act.
  • National and International Standards.
  • Local Metropolitan Council Regulations.

    Notes to Assessors:

    Assessors should keep the following general principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title.
  • Assessing outcomes related to the demonstration of the understanding of principles/concepts:
    > Develop an assessment which uses prior evidence as produced in written examinations.
    > Develop additional written assessment tools to supplement undependable sources of evidence in the previous bullet.
  • Assessing outcomes related to "perform operational activities on SDH/PDH systems"; Make sure evidence is gathered across the entire Unit Standard range, wherever it applies:
    > Assessment activities should be as close to the real workplace practical performance as possible, and where classroom simulations are used, there should be supporting evidence to show the candidate is able to perform in the real situation.
    > The assessment activities relating to configuration of systems should assess all basic configuration requirements.
    > The assessment activities relating to fault repairs on systems should assess all basic fault repair and test equipment usage requirements.
  • Do not focus the assessment activities on each assessment criterion. Ensure that the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The task of the Assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the candidate can achieve the outcomes again and again and again. This means Assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: appropriateness, fairness, manageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent.
  • Requirements for a portfolio are that it should be valid, reliable and authentic evidence (presented as a portfolio of evidence) from past achievements and experience, which serves to supplement the assessment of applied competence.

    The portfolio may not include:
  • Evidence older than 3 years prior to the date of assessment.

    The portfolio may include:
  • Written statements from persons (e.g. current and/or previous employer, colleague, peer, manager, external customers) confirming competence of the learner.
  • Relevant certificates or awards.
  • Previous assessment records.
  • Journals/logbook.
