I'm studying for CID course and i've the CID book,but i find on Cisco site about CID some topics that aren't covered in the book that's with me like: 1- VPN architecture,benefits and security. 2- Describe the PCM process for encoding an analog signal into a digital stream of 1s and 0s 3- Define local loops, trunks, and interswitch communications 4- Describe the types of PSTN signaling methods 5- Describe voice signaling types 6- Identify key voice over packet network design considerations 7- Describe the phases of an IP Telephony call So what's wrong with my book?? Is there a new edition for the CID book covering those topics. My edition is 2000.
