Describe broadband access technologies (ADSL/VDSL, GPON, Ethernet FTTH, fixed wireless) and compare their upstream/downstream capacity and typical loop limits.

Explain cellular concepts: cell, sector, frequency reuse, handover, roaming, and the difference between FDMA, TDMA, CDMA, and OFDMA.

Describe antenna fundamentals (gain, directivity, polarisation, VSWR, beamwidth) and calculate free-space path loss for two given link distances.

Explain optical fibre structure, total internal reflection, single-mode versus multimode fibre, and the causes of attenuation and dispersion.

Identify the main fibre cable components (core, cladding, coating, strength members, sheath) and describe the purpose of each.

Describe copper cabling practices: pair colour codes, twisting, shielding, punch-down termination, and the effect of untwisting on crosstalk.

Sequence the steps of fibre splicing and jointing, including stripping, cleaving, fusion splicing, splice protection, and closure sealing, and state the acceptance criteria for splice loss.

Explain test methods: optical power meter and light source, OTDR trace interpretation, and copper tests such as continuity, loop resistance, insulation resistance, and insertion loss.

Apply laser safety rules for optical work, including never looking into a fibre end and safe disposal of fibre offcuts.

Describe the installation sequence for a subscriber connection: survey, cabling route, drop cable, termination at the distribution point, NTP/CPE connection, and commissioning tests.

Diagnose faults systematically using a divide-and-conquer approach, distinguishing subscriber-side, drop-side, exchange-side, and power faults.

Explain CPE including ONT/ONU, modems, routers, Wi-Fi access points, and telephone instruments, and describe typical configuration parameters for each.

Prepare a fault-diagnosis decision tree for the three most common complaints: no dial tone, no internet, and slow speed.

Describe preventive maintenance routines: battery checks, earth resistance measurement, cleaning of connectors, and record-keeping for equipment history.

Review and re-solve the weakest question types from weeks 1-5, targeting at least 80% accuracy on a 40-question mixed set.

Explain RF safety limits, antenna installation precautions, earthing and lightning protection for towers and shelters, and the purpose of each.

Describe battery bank maintenance for telecom sites: specific gravity, float and boost charging, capacity testing, and the risks of over-discharge.

Explain fibre and copper documentation requirements: cable records, splice schedules, as-built drawings, and how to update them after a repair.

Practise interpreting equipment alarms and status indicators on a typical exchange or transmission rack, and state the first response to each alarm class.

Identify the main occupational hazards in telecom field and exchange work, and state the control for each using the hierarchy of controls.

Explain electrical safety practices: isolation and lock-out/tag-out, proving dead, use of PPE, and safe working near live equipment.

Describe working-at-height and confined-space controls for tower, pole, and manhole work, including permits, harness inspection, and rescue arrangements.

Explain environmental responsibilities: e-waste handling, battery and fibre offcut disposal, chemical safety, and spill response.

Summarise the Indian telecom sector landscape, key institutions and their roles, and the main employment and self-employment opportunities for a trained technician.

Draft a short business case for a small telecom servicing enterprise covering service lines, pricing, and customer acquisition.

Complete two full-length mock exams under timed conditions and score at least 80% on the second attempt.

Revisit every flagged or uncertain item from the whole course and resolve each to a confident answer with a written justification.

Recite from memory the key formulas, colour codes, layer mappings, and safety rules using spaced-repetition cards over five separate days.

Build a personal one-page exam-day reference sheet containing only facts you have verified, and rehearse using it in a timed drill.
