Making the Connection: Voice Over IP Over Broadband Cable

Synopsis
This course was developed to assist cable operators' technical personnel in understanding the essentials of this compelling development in the industry's capability -- and the implications to their work responsibility. This course provides the student with a thorough treatment of the important aspects of developments in the provisioning of voice services over Internet Protocol over the broadband cable infrastructure. It provides a logical, understandable guide to the applicable technologies with an emphasis on the requirements of voice telephony service.

Who Should Attend
The course will appeal to a large cross-section cable industry people with an interest in this revolution that is overtaking both the traditional telephone industry and the cable industry.

Technical personnel -- managers and technical staff would all benefit from this clear, introductory-level presentation of the issues that are driving this revolution.

Course Material and Program Features
Where a live Internet connection is available in the classroom, this course program is presented with a series of IP applications used as demonstrations and/or workshop activities, as priorities permit.

Each student is provided with a comprehensive workbook which is much more than a set of lecture notes. In addition to being a workbook designed to track with the lecture portion of the program, its features give it real value as a permanent reference book.

These include:

• All of our presentation materials are developed in the form of complete fully descriptive sentences, designed to be a highly readable, valuable reference on the job.
• A text-book style Subject Index and a comprehensive Table of Contents, both designed to make sure the information in our manuals is easily accessible for future reference.
• A thorough, highly useful subject-specific glossary providing detailed descriptive treatment of essential items of terminology.
