  • Conversation and body language can enhance communication. Interactive teaching strategies such as questioning and discussion can involve and motivate learners. Remote experts can validate understanding and provide practical examples. The real-world connection improves motivation. Graphics and photos look great on video and can help to communicate a difficult concept Some systems allow application sharing which encourages collaboration and feedback in real-time.
  • The basic service is intended to meet the needs of most individual users. PRI is intended for users with greater capacity requirements.
  • A telecommunications network is designed in a series of layers. A typical configuration may have utilized a mix of time division multiplexing, Frame Relay, ATM and/or IP. Within a network, carriers often extend the characteristic strengths of ATM by blending it other technologies, such as ATM over SONET/SDH or DSL over ATM. By doing so, they extend the management features of ATM to other platforms in a very cost-effective manner.

    29. 29. Videoconferencing <ul><li>Conclusion </li></ul><ul><li>Conferencing technologies enable real-time interaction of students and teachers with experts, collaborators, and organizations all over the globe. Conferencing is often more convenient and less expensive than travel, and a wider audience can be reached. Education can truly become a classroom without walls. The major limiting factors are bandwidth, technical training, and equipment and software expenditure. </li></ul><ul><li>One last word of advice is to always keep in mind that conferencing takes careful planning and preparation. Guest appearances must be arranged ahead of time, equipment must be checked out, set up, and tested, and participants need to learn the basics of the technology and its use. </li></ul>
