PTT Level 3 Certificate in Unified Communications - Syllabus

 

Study Aim: To describe the fundamental principles, protocols, components, applications, testing, and security aspects of unified communications systems.

Topics covered: The study programme begins by introducing the fundamentals of analogue and digital transmission, data communications and the different types of cabling and connectivity. Learners continue with a study of LANs and WANs including diagnostic tests. The programme concludes by ensuring the learner appreciates the services a unified communications system provides and understands how such a system meets the requirements of different types of traffic and ensures data and system security.

What you need before beginning this programme: Although not obligatory, the study of Physics at secondary (high) school level will aid your understanding of the principles covered in the study programme.
