Telecommunications Fundamentals |
|
Course Description |
|
A new era in telecommunications has exploded with the adoption of Voice over IP
(VoIP), third generation (3G) mobile, and next-generation voice and data services.
Telecom is undergoing a series of radical changes which is molded by the legacy
of telephony and an Internet Protocol network.
This comprehensive course provides you with an in-depth understanding of the current
telecom landscape and how voice is migrating from a circuit- to a packet-switched
network. You will learn how to evaluate existing technology options to determine
which will best meet your organization's data and telephony requirements, from mature
digital transport/access services to emerging voice and data services using voice
over packet technologies.
The technology, marketplace, and regulatory structure of telecommunications are
in a continuous state of transition. This powerful course will ensure that you fully
understand the service options available to your organization and how voice technologies
integrate into your existing data networks
