   2.  Identify key applications of Internet telephony.
   3.  Identify the goals of using voice over Internet Protocol (VoIP).
   4.  Identify the seven key applications of VoIP.
   5.  Differentiate between the Public Switched Telephone Network (PSTN) and the
       Internet for voice transmissions.
   6. Define Pulse Code Modulation (PCM) and identify the three steps in PCM.
   7. Define gateway.
   8. Identify the steps to make an Internet call.
   9. Define intranet and differentiate between the Internet and an intranet for VoIP.
   10. Identify the key challenges to VoIP.
   11. Identify the five functions of the VoIP.
   12. Define the Gatekeeper function and the connection function.
   13. Define voice compression and decompression.
   14. Identify the role of the COder/DECoder (CODEC).
   15. Define "talk spurt."
   16. Define fax demodulation and remodulation.
   17. Differentiate between User Datagram Protocol (UDP) and Transmission Control.
   18. Identify common analog and digital interfaces.
       19. Describe T1 and E1 connections.
       20. Define bandwidth, half-duplex, full-duplex and silence suppression.
       21. Describe the trunk duty cycle and define calculations for duty cycle.
       22. Identify the effect of truck duty cycle on bandwidth consumption.
       23. Define carrying capacity and residual capacity for VoIP.
       24. Explain the significance of Quality of Service (QoS) to VoIP.
       25. Define network delay and jitter, and identify solutions to network delay and jitter.
       26. Define packet prioritization and segmentation, and identify the role of
           prioritization and segmentation in maintaining QoS for VoIP.
       27. Identify the role of silence suppression in maintaining QoS for VoIP.
       28. Define echo cancellation and identify industry standards for echo cancellation.
       29. Identify the role of echo cancellation in maintaining QoS for VoIP.
       30. Identify the role of the gateway in maintaining QoS for VoIP.
       31. Differentiate between using a Personal Computer (PC) as a phone, and using a
           VoIP gateway.
       32. Identify advantages of, and applications for, using a PC as a phone.
       33. Identify "G.7xx" standards and define "G.723.1".
       34. Identify "H.2xx" standards and define "H.323".
       35. Define Resource Reservation Protocol (RSVP).
