Telecommunication is the transmission of signs, signals, messages, writings, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology. It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are often divided into communication channels which afford the advantages of multiplexing. The term is often used in its plural form, telecommunications, because it involves many different technologies.
There are multiple telecommunication courses such as:
Core Telecom Training: CTNS Courses
2201: The PSTN
2206: Wireless Telecommunications
2212: OSI Layers and Protocol Stacks
2211: Ethernet, LANs and VLANs
2213: IP Addresses, Packets and Routers
2214: MPLS and Carrier Networks
In this online telecommunications course, we begin with a history lesson, understanding how and why telephone networks and the companies that provide them are organized into local access and inter-city transmission, or as we will see, Local Exchange Carriers (LECs) and Inter-Exchange Carriers (IXCs).
Then we will establish a basic model for the PSTN and understand its main components: Customer Premise, Central Office, loop, trunk, outside plant, circuit switching, attenuation, loop length, remotes, and why knowledge of the characteristics of the loop remains essential knowledge even though we are moving to Voice over IP.
Voice over IP and SIP Courses
2221 Fundamentals of Voice over IP
Fundamentals of Voice over IP is a complete introduction to everything Voice over IP. You’ll learn the fundamental ideas and principles of a VoIP telephone system, VoIP, SIP & all the other jargon – what it actually means and how it all works together.
At each step, we’ll also cover supporting and related technologies like Ethernet MAC frames and codecs and video over IP.
