The generation, transmission, and reception of Frequency Modulation (FM), and Phase Modulation (PM) signals are covered. The students will be introduced to the theory of digital modulation and spread spectrum radio transceivers. Laboratory exercises will instruct in the proper use of RF test equipment and manuals for evaluation of a communication transceiver. The operational principles of RF transmission lines including: characteristic impedance, Voltage Standing Wave Ratio (VSWR), impedance matching and attenuation are discussed. The correct application and tuning of an RF cavity filter are detailed. Prerequisites: TELX 2113

The importance of communication skills is emphasized in this course. The student will learn how to communicate effectively with customers and employers. The student will design a resume for submission to prospective employers. Interview techniques and job search skills are also examined. Public speaking skills are practised and given a peer-based review. Self-employment options including business start-up and sub-contracting will be studied. Effective evaluation of possible choices in business decisions will be undertaken utilizing objective decision making concepts.

The final course in Telephony will focus on security issues affecting modern telephone equipment. External access to the PABX for maintenance and security issues will be explored and corrective measures to protect the equipment and software will be performed. Set and Trunk restriction lists will be created on the network to limit universal access to the Public Switched Telephone Network (PSTN) and business network. The development and configuration of security policies and traffic monitoring will be undertaken. Advanced programming of PABX features such as: Least Cost Routing (LCR), Call Distribution, Skillset Management and Protection Routing will be analyzed. Prerequisites: TELX 2113 and TELX 3112 and TELX 4114

The requirements of a business with multiple branch locations will be analyzed, and telephone features useful to this type of operation will be discussed and configured on the PABX. A Local Area Network (LAN) using Transmission Control Protocol and Internet Protocol (TCP/IP) will be established to provide Web Browser access to the switches, and allow exploration of VoIP Telephony. Advanced PABX configurations including remote Voice Message access, Custom Call Routing and a Uniform Dial Plan will be implemented in a functional multi-PABX network. Prerequisites: TELX 2113 and TELX 3112
