Many of these corrections are minor, such as Web site address updates and related entries to topics that were removed. By far, the biggest problem is on page 168, where the heading to "Cable (CATV) Data Networks" somehow ended up on page 172. See "Page 168" below to make this change, or click here for the corrected text.

The heading for "Cable (CATV) Data Networks" somehow ended up on page 172 in the page layout process. The heading and the first three paragraphs on page 172 should be just above the "CATV Architecture" heading on page 168. You could copy page 172 and then place a cut-out above the heading on page 168. Sorry about this!!! Go to http://www.linktionary.com/c/cabledata.html to view the Web page for the corrected text.

In Figure C-22, within the lower-left circle, change "SEQ #=Y" to "SEQ #=X+1" Thanks to Gert Muller (an electronic engineer at Mide Technology Corp.) for catching this. X represents the client. The sequence number is incremented for each message the client sends, so this portion of the figure should read X+1. Note that I had this correct in my original hand-drawn art. The illustrators used copy and paste to create the figure, then forgot to change the text. Please let me know if you find similar things. I tried to catch all this stuff when reading page proofs, but missed this one.
