 [Preface]





Bring today's most powerful network technologies to residences and business:

  • Cable Modems
  • Video On-Demand
  • High-Speed Internet Access
  • Video Conferencing
Today's consumers want the same quality of communication services on their local loops that they've been getting in the workplace. High-speed communication technologies are now available to bring Internet, video, and other electronic functions to residential and business users through local service providers, based on existing infrastructure. This book shows you how.

Residential Broadband Networks covers the system standards, hardware requirements, and available software for these delivery systems:
  • Digital Subscriber Line (DSL)
  • Asymmetrical DSL (ASDL)
  • Hybrid Fiber-Coax (HFC)
  • Wireless Local Loop
Detailed coverage is given to GR-303 requirements, with a special focus on Integrated Access Systems. Cutting-edge digital technologies are related to exiting fiber optics and ATM systems, with a view to the next generation of protocols for residential broadband communications.

Readers around the world trust Uyless Black for his straight talk about complex technologies. With Residential Broadband Networks, he brings the latest developments to life for communications engineers serving residential customers.
