TeleCom Networks Today I
The Make-Up & Structure
Course Description
The make-up and structure of telecommunications networks has changed drastically. These changes affect the equipment you purchase, the services you buy, the providers you can choose, and the media you use for transport. One call will no longer take care of all your needs. Without a full understanding of the changes that occurred and how they have affected voice and telephony services, products, and technology, you and your network will become obsolete.

This course will provide you with the basics of voice call processing, features, and hardwaresoftware solutions. If your network is converging, you need to comprehend voice technologies to complement your data knowledge. If you are trying to sell or market services, this course will help you with the buzzwords, the technology, and the applications.
Students Will Learn
