Overview
Telecommunications Technologies is not a bits and bytes course but rather gives students an understanding about how all the pieces fit together and how they can be leveraged into business opportunities. Students learn about the growth and development of the PSTN, Cable, Mobile and Internet worlds.
SS7 and SIGTRAN protocols, being critical infrastructure, are covered in sufficient detail to allow students to appreciate their capabilities and power and extensive use is made of call animation scenarios to enable students to visualize where, and how, value-added call processing can be added. VoIP (SIP) functionality is described and mapped onto its equivalent functionality in the traditional telephony world (Mobile, PSTN). At the end of the course students design, and outline the implementation of, value added services for PSTN, Mobile, Cable and VoIP networks.
Audience
The course is designed for marketing, planning and business development personnel working within the Service Provider and equipment supplier industries for VoIP, Cable, Mobile or the PSTN, together with those who need a thorough understanding of the architecture and business opportunies available within the current telecommunications environment. A reasonable understanding of computing or telecommunications systems is a prerequisite for the course.
