Course Overview

Course in a Nutshell

We will begin with the fundamentals needed to understand CALEA implementation in conventional Time Division Multiplexing (TDM) circuit voice networks and the emerging IP-packet based Voice over IP (VoIP) and Unified Communications systems. This will be followed by a comprehensive discussion of the CALEA concepts, issues, requirements, and implementation.

 

Customize It!

Customize this course to your group’s requirements at little-to-no added cost. We can teach this course from the law enforcement perspective or that of carriers and service providers.
This course can be extended to cover conventional and/or packet voice concepts and details in more depth; or shortened, covering CALEA only for audiences who are already knowledgeable in voice systems.

Audience / Prerequisites

Aimed At

Law enforcement officers and agents who must understand conventional TDM telephony technologies as well as their emerging packet-based counterparts as they relate to CALEA as well as carrier and service provider personnel responsible for CALEA compliance.

 

Prerequisites

You should have a basic understanding of TDM circuit and IP packet network operations and protocols.
