This new issue of Telcordia Notes on the Networks replaces Issue 3 and brings
you the latest technology information, including the important developments that
have occurred in the telecommunications and information networking industry
during the past few years. In this issue you will learn about:

• How the rapid growth of Internet Protocol (IP)-based networks and
  packet-based converged networks (Next Generation Networks) that support voice,
  data, and video communications accommodate and support the explosive growth of
  the Internet and e-business.


• The effect of the explosive growth of mobile phones and wireless networks
  and what it means to you as a supplier of telecommunications services.


• The impacts from recent government laws and regulations and how they affect
  your competitive position and network operations (for example, the
  Telecommunications Act of 1996 has fueled the growth of many Competitive Local
  Exchange Carriers [CLECs] with impacts on dialing plan and interconnections; and
  the impacts of the Communications Assistance for Law Enforcement Act
  (CALEA) are just starting to be felt in industry.

Notes is written with two audiences in mind: the technical and nontechnical
reader. While it provides sufficient detail to serve as a reference document for
the technical reader, it is also written to distill technical concepts in such a
way that they are understandable to the nontechnical audience.
