Assist in the replacement of telecoms equipment
Overview
This standard identifies the competences you need to assist in the replacement of operational telecoms systems and equipment under direction. Replacement of the equipment can be as a result of maintenance or fault-finding activities. The telecoms equipment in this standard can be for overground or underground rail transportation systems.
You will be required to use the appropriate tools and equipment throughout the replacement activities, apply a range of removal and installation methods and techniques to replace the equipment and make connections as appropriate to the equipment installed. Where appropriate, you may also assist in working with computers or electronic controllers, making connections, installing hardware and loading and updating software. The replacement activities will include making checks and adjustments, in line with your permitted authority, and assisting others to ensure that the replaced equipment functions to the required specification.
You must check that all tools, equipment and materials used in the replacement activities are removed from the work area on completion of the work and that the relevant job/task documentation is completed accurately and legibly.
You will be expected to work to instructions in conjunction with others. The replacement activity may be carried out as a team effort, but you must demonstrate a significant personal contribution to the activities to satisfy the requirements of the standard and you must demonstrate competence in all the areas required by the standard.
Safety is a key theme throughout this standard. You will be able to take all relevant action to ensure the safety of yourself, others and railway operations.
Performance criteria
You must be able to:
P1 maintain safe working practices and comply with all relevant health and safety regulations, directives, and guidelines

P9 observe sufficient operations of the equipment to confirm it is functioning as intended
P10 report completion of activities in line with your organisation's procedures
P11 address problems within your control and report unresolved issues

K9 the hazards associated with carrying out telecom replacement activities (such as stored voltages, radio frequency radiation, electrical supplies, electrical/electronic interfaces, using damaged or ill-maintained tools and equipment, not following laid-down procedures), and how to minimise these and reduce any risks
K10 the relevant methods, techniques and procedures for removal and installation activities
K11 how to source and follow relevant technical information, standards, diagrams, instructions, specifications and schedules for replacement of telecoms equipment
K12 your organisation's procedures for the use, care and control of tools and equipment
K13 the procedures and precautions to be adopted to eliminate electrostatic discharge (ESD) hazards when working with and handling electronic devices
K14 how and when damage may occur to equipment during replacement
K15 how to select the correct tools for the activity, including how to confirm that they are calibrated and stored in accordance with your organisation's procedures after use
K16 how to identify the various types of connectors used and the correct tools and equipment to make the disconnection and connections
K17 the different types of mounting, connecting and cable supporting systems used in the replacement of the telecoms equipment
K18 the relevant reporting lines and procedures that are approved by your organisation
K19 the limits of your own authority and responsibility and those of others involved
