Terminal Course Objectives
DeVry University course content is constructed from curriculum guides developed for each course that are in alignment with specific Terminal Course Objectives. The Terminal Course Objectives (TCOs) define the learning objectives that the student will be required to comprehend and demonstrate by course completion. The TCOs that will be covered in detail each week can be found in the Objectives section for that particular week. Whenever possible, a reference will be made from a particular assignment or discussion back to the TCO that it emphasizes.
A
Define and describe what IP Telephony/VoIP is and is not, and describe the current landscape of the IP Telephony/VoIP arena. Specifically, describe where IP Telephony/VoIP is being used today and identify where it came from, what technology preceded it, and how it integrates into the existing Telecom Architecture (TDM equipment and network services (PSTN)) in place today.
B
Examine IP Telephony/VoIP fundamentals, including but not limited to: QoS; Codecs and Protocols; Terminology Network Assessment; Applications; and Architecture.
C
Define the current use of the protocols that support IP Telephony/VoIP. Which ones are they? Do they interoperate (play) together?
D
Given the existing LAN/WAN infrastructure in place at many firms today, evaluate the issues involved with deploying IP Telephony/VoIP into that environment. How do these technologies integrate with each other? Additionally, when a firm is ready to deploy IP Telephony, what is needed/involved from a network assessment perspective to ensure that the "network" is ready for VoIP and Multimedia Subsystems?
E
Given the evolution from "Dial Tone" to "Data Tone", how does IP Telephony/VoIP fit? Does voice simply become an application on the data network, or is there more to it than that? What strategic advantages does IP Telephony/VoIP offer to today's firms?
F
Given the changing telecom architecture, identify selected markets and applications for IP Telephony/VoIP at present and for the future.
G
When looking at the following IP Telephony/VoIP architectures, how does a firm decide on deploying one of them? The architectures are: Hybrid; H.323; and SIP. Does each particular architecture have its own place, or is one determined to be the dominant architecture for IP Telephony/VoIP deployments?
H
Review the current uses of IP Telephony/VoIP today. Taking this into account, identify trends that are just developing and where IP Telephony/VoIP will be used in the future. Specifically, what technology is changing/evolving that will give rise to new and different use of IP Telephony/VoIP in the future?
