Course Description:

As well as focusing on the major telecommunications technologies, this course looks in detail at the services available and how they may delivered over a range of network types. After a detailed consideration of the structure and operation of the PSTN and ISDN the course continues with a look at the principal transmission technologies including the Plesiochronous Digital Hierarchy (PDH), Synchronous Digital Hierarchy (SDH), and Optical Transport Network (OTNs). Following this the course deals with cellular network technologies including GSM, GPRS and 3G. The types of data communication network currently available are then considered. This includes discussions on Frame Relay, ATM followed by Ethernet, Internet Protocol and Multiprotocol Label Switching. Subsequent sections deal with broadband access technologies and the role of Next Generation Network, including the IP Multimedia Subsystem, in providing Voice over IP (VoIP) services.

Who will Benefit:

This is a must-have course for all current and aspiring telecom professionals, including IT staff, business decision-makers, consultants and sales staff, and students. The Telecom Crash Course is the easiest way to get up to speed quickly to excel in this field.


An aptitude for a technical role or a background in engineering is desirable.
