WBCHSE HS Vocational Telecom study plan

Define and compute Ohm's law, series and parallel resistance, and power in DC circuits, solving at least 20 numeric problems by hand.

Explain the working of resistors, capacitors, inductors, diodes and transistors and identify their circuit symbols from memory.

Describe the decibel and calculate voltage, current and power ratios in dB for given telecom link values.

Distinguish analog and digital signals, and compute amplitude, frequency, period and wavelength for given waveforms.

Analyse half-wave and full-wave rectifier circuits and explain how a filter stage smooths the output.

Compare amplitude, frequency and phase modulation in terms of bandwidth, noise immunity and application.

Explain sampling, quantisation and PCM encoding, and calculate bit rate for a given sample rate and bit depth.

Identify the blocks and signal flow of a basic telecom transmitter and receiver chain.

Compare twisted pair, coaxial cable and optical fibre on bandwidth, attenuation, cost and interference immunity.

Identify conductor, insulation, shielding and jacket layers in a cable cross-section and state the role of each.

Explain pulse code modulation hierarchy, line coding and multiplexing (FDM, TDM) with simple numeric examples.

Describe the function of a telephone exchange and trace a call setup, call hold and call release sequence between two subscribers.

Explain switching types (space, time, digital) and the role of the subscriber line circuit, trunk and control unit.

Compute traffic intensity in erlangs and use it to explain blocking in a simple trunk group.

Describe cellular architecture: cell, cluster, frequency reuse, handover and roaming, and calculate the reuse factor given a cluster size.

Compare multiple access schemes FDMA, TDMA and CDMA in terms of spectrum sharing and capacity.

Map the OSI and TCP/IP models, naming the protocol and device operating at each layer.

Configure an IPv4 addressing scheme: subnet a given network into a required number of hosts and verify broadcast addresses.

Explain Ethernet, IP routing basics, DNS and HTTP request flow when a browser opens a page.

Describe optical fibre construction, total internal reflection, single-mode versus multimode, and typical attenuation and splice loss values.

Describe installation practice for cable routing, dressing, termination and earthing of telecom equipment.

Explain fault-finding procedure for a dead subscriber line: test points, continuity, insulation and loop resistance checks.

Compare broadband access technologies: ADSL, FTTH, GPON and cable, on downstream speed, medium and typical deployment.

State preventive maintenance checks for an exchange or base station, including battery, cooling and alarm logs.

Identify electrical, fall, chemical and RF hazards in telecom work and state the control measure for each.

Explain earthing, shock response, PPE use and safe handling of optical fibre waste and laser sources.

Draft a simple business plan outline for a telecom installation or repair service, covering market, cost and pricing.

Practise customer interaction: greeting, explaining a fault, and handling a complaint, and list the employability skills an employer expects.

Assemble and test a small circuit such as a rectifier or LED indicator on breadboard and record measured versus calculated values.

Terminate a twisted-pair cable and verify continuity and pinout with a tester, recording results.

Revise weak areas flagged in the week 4 error log and re-solve those items.

Complete two full-length timed mock papers under exam conditions and review every wrong answer.
