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.
- 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!
