Appendix A: Getting Acquainted with Tenor CMS in the VoIP Network

Common Network Types

Intranet

An Intranet (also known as Enterprise IP network) is a private "Internet web site" which uses the Internet Pro- tocol (IP) to deploy VoIP services, such as the CMS, within your company from a dedicated web server. This web site is separate from your external web site for security reasons. Intranets can be deployed within your company over the internal LAN, or a number of LANs at corporate sites connected by an IP WAN or IP Vir- tual Private Network (IP-VPN). A major benefit of using an Intranet when deploying VoIP services is that the network architecture is well defined to ensure that network delay, latency, and packet loss are predictable.

Extranet

An Extranet is similar to an Intranet except that it is externally accessible by a limited number of people on a secure basis. Because Extranets are based on Internet technology and use the Internet Protocol (IP), they may be used for deploying VoIP services, such as the CMS. A major benefit of using an Extranet when deploying VoIP services is that the network architecture is well defined, to ensure that network delay, latency, and packet loss are predictable.

Internet

The Internet is a universally accessible public packet switched network. It consists of a Global network of high speed computers and packet routers connected in a complete mesh structure. This network uses the stan- dardized Internet Protocol (IP) to pass packets from point to point within the network by data routers. The connection between two routers is called a “hop” and a typical connection will consist of many hops. The number of hops will determine the delay and latency in the connection. Congestion may cause packets to be lost within the network. The Internet was designed to provide data communications on a “best available con- nection” basis and does not guarantee any “Quality of Service”. This mode of operation is suitable for data and E-mail transmissions which are not delay sensitive, but it is not real-time data streams such as voice or video.
