CITX 1186 - Cisco CCNA Voice

Computer Information Technology Electronics Part-time Studies Course

School of Energy

Course Details

This course first explores the operation of traditional telephone systems and the public switched telephone network (PSTN). Topics include analog to digital conversion, the North American digital hierarchy, local loop operation, and call routing considerations. Next the course moves to the fundamental of Voice over IP (VoIP) and how voice information is packetized. An examination of the infrastructure required to support VoIP along with the protocols used allows the students to deploy IP based phones within the lab. With basic operation in place more advanced voice features are explored and the students configure, customize, and troubleshoot the infrastructure and its functionality. Topics include how to setup IP phones, configure users, how to configure phones and users for Class of Service, configuration of user features such as Do Not Disturb, Conferencing, Shared Lines, and Barge. Multiple site operation and connectivity is discussed along with integration to the PSTN. Topics include dial plans, bandwidth management, and call admission control. With reliability a major concern, students explore options to provide redundant and/or backup connectivity within the VoIP infrastructure. Students must have access to a Windows based multi-media computer.

Prerequisite(s)
