CCNA Wireless Official Exam Certification Guide (CCNA IUWNE 640-721) ReviewPerhaps this text would be appropriate for somebody seeking the CCNA Wireless certification, but this book seriously falls short on wireless and radio fundamentals. In the opening chapters the author introduces the concept of phase before he even describes a waveform and its components. It also contains a lot of inaccuracies. He goes into detail about the differences between DSSS bit rates and their associated encoding techniques but barely describes OFDM or 802.11n at all.
For those seeking knowledge on how to pass the CCNA Wireless exam and how to configure Cisco AP components, this book is a necessary acquisition but those who are seeking solid entry knowledge into the world of 802.11 administration should check out the CWNA book from Sybex.CCNA Wireless Official Exam Certification Guide (CCNA IUWNE 640-721) OverviewCCNA Wireless Official Exam Certification GuideMaster IUWNE 640-721 exam topics with the official study guideAssess your knowledge with chapter-opening quizzesReview key concepts with Exam Preparation TasksPractice with realistic exam questions on the CD-ROMCCNA Wireless Official Exam Certification Guide is a best of breed Cisco® exam study guide that focuses specifically on the objectives for the CCNA® Wireless IUWNE exam.

Cisco Unity Connection (Networking Technology: IP Communications) ReviewSchulz's book can be considered as two parts. The first part, covered in the chapters 1 and 2, is the overview and planning. Its strongest recommendation seems to be to design in as much detail as possible your computing network for voicemail. Especially take into account scalability. Future expansion should be considered from the start. The CUC core product can handle up to 20 000 users on a single server, which is certainly impressive. But if even this is insufficient, you have the choices of using more servers or perhaps digital networking and VPIM [Voice Profile for Internet Mail] to extend the limit on one server.
VPIM is also important, for it lets a CUC network with another vendor's voicemail system, if the latter also supports VPIM. A pragmatic concern if your company already has that other vendor's system deployed as a legacy centre.
One important aspect is the geographic distribution of users. The book uses an example of a company with its employees mostly on both US coasts. For high availability, this suggests deploying a server on each coast. Then CUC lets you build an intersite network so that you can easily administer just one unified voicemail centre.
The second part of the book is the majority of the text. It delves into the many details of system administration of CUC. Accompanied by numerous screenshots of windows of supported options. One of which I describe here, as especially pertinent to voicemail. It has to do with message aging. Voicemail is stored as WAV files, and it is inherent that a typical voicemail is larger than your standard email, even if the latter is in HTML, as many are these days. So voicemail takes up more room than email. To handle this, CUC offers a message aging policy. Users can move a voicemail into a Deleted Items folder. But the voicemail still exists in the system, taking up space. You can adjust a number of days parameter, so if a voicemail is in the folder after that limit, it is permanently deleted.Cisco Unity Connection (Networking Technology: IP Communications) OverviewCisco Unity ConnectionThe comprehensive guide to Cisco Unity Connection voice messaging system design, implementation, and troubleshootingDavid SchulzCisco Unity Connection presents all the concepts and techniques you need to successfully plan, design, implement, and maintain Cisco Unity Connection voice messaging systems.
