      %T "Implementing ADSL"

      ADSL (Asymmetric Digital Subscriber Line), along with many other new
      and desirable telecommunications technologies, is all too often
      presented in one of two ways. Either you get "this is new, and you
      need it!" uninformative boosterism, or you get packet structure
      specifications for those who need to program the core protocols into
      switches. It is, therefore, gratifying to find a book that gives you
      the hard core, and hardware, realities of the system.

      Chapter one presents the business case for ADSL, based on the usual
      "Internet users want more bandwidth" model, plus a budget relying on a
      number of relatively unsupported suppositions and the American
      telephone network business. Ginsburg does make a very important point
      all too often lost in other works: ADSL is not a networking protocol
      as such, but is more akin to a modem specification. Therefore the
      discussion of encoding methods that begins chapter two is very welcome
      for those who need to use and understand the technology, rather than
      merely programming packets. The further material on ATM (Asynchronous
      Transfer Mode) and alternate options (such as frame relay and Internet
      Protocol) at the higher layers helps the reader to see how these
      systems work together.

      Chapter three outlines the components of the ADSL architecture
      throughout a network, with the hardware parts mentioned being perhaps
      more directly related to that topic than the software that is
      reviewed. Many of the services presented in chapter four actually
      rely on ATM, PPP (Point to Point Protocol) and other higher layer
      protocols. Implementation is covered, with detailed configuration
      examples and screen shots from real products, in chapter five.
      Chapter six addresses the technology alternatives for providing high
      bandwidth access to the public.

      (By the way, a thousand fold increase is 100,000 percent, not 10,000
      percent, and a hundred fold increase is 10,000 percent, not 1,000
      percent. You're welcome.)

      This book will, indeed, be useful for those implementing ADSL.
      Service providers will find a wealth of information that has probably
      been confined to the engineering department up until now. Users will
      finally get a chance to understand what ADSL actually is, and where it
      fits into the rest of the alphabet soup.
