Hands-On Evolving Telecommunications to Triple Play: IPTV, VoIP and TV Delivery Systems for System Engineers-DataCom

Course Description

With the introduction of Next Generation Networks to telecommunications carrier infrastructures, customers expect a full range of Triple Play services. These include High-Speed Internet Access, Voice Telephony and Television delivered over the same network interface. These customers may be domestic where service is delivered directly into homes, business where increasing richness of multimedia content allows businesses to communicate more effectively or in military where remote stand-off control or information gathering becomes feasible.

Ideally high bandwidth fiber optic communication would be used for new richer services. However existing infrastructures often contain copper loops and for economic reasons these must be used to deploy these services. Careful design of services that work within these more restricted bandwidths is therefore important. This is one of several key challenges to delivering IPTV. It will be necessary to deliver TV quality that can match existing over-the-air and cable delivery. It will also be necessary to ensure that all services can be delivered together and will not significantly affect the performance of other services. Also that voice services can be interfaced to existing telephone networks so that they will integrate into the standard telecommunications infrastructure used around the world.

This course will provide an understanding of the technologies being used to deliver a range of services including voice, point to point video, broadcastmulticast TV and HDTV. It will provide a technical understanding of the different RF, wired and cable standards used for distributions and delivery. I will further provide hands-on exercises which will demonstrate how voice, multicast IPTV, Video on Demand and Web Television can be delivered over a common IP infrastructure.

The course will used standard Windows PC or Laptop computers running Windows XP or Windows 7 attached to an in class LAN and emulated WAN infrastructure isolated from live infrastructures allowing the demonstration of all services without firewall and security restrictions. The course exercises will use free and open source software allowing attendees to build systems which can be transferred to home, or business systems with little or no operational cost allowing further learning and experiment.

This course can be delivered on-site or in a conference facility with a hotel, in a room provided with PCs or Laptops running Windows 7 or Windows XP connected to an in class LAN using RJ45 Ethernet connections. All other networking equipment will be shipped in for connection and Hands-On Labs for the training.
