Remarkable sales for three successive editions have made it the bestselling ISDN book of all time. Now Kessler and Southwick's one-volume resource is bigger and better than ever, covering all the latest developments in broadband communications--including ADSL, IP switching, and Ipv6--while retaining the encyclopedic treatment that has distinguished it as the definitive reference on the subject.
