Sample network configuration
In the sample network, the New York Main Office and the Los Angeles and San Francisco
branch offices are using the KX-TDA0480 to realise low-cost voice and fax communications
through the IP network.
This sample is used throughout this manual to illustrate network and unit configurations. Also
see the IP addressing and numbering plan network diagrams in Appendices A1 and A2.
And this network is configured using the KX-TDA0480's internal DNS functions to manage
network IP address-to-telephone number translations. See Appendix A3 for details regarding
this function.
Although the sample network described above illustrates many of the KX-TDA0480's
capabilities, it represents only one of many possible network configurations. The various
features and methods for implementing KX-TDA0480 products are discussed in greater detail
in the following sections of this guide.
Whatever the configuration envisioned, when planning a network installation, take care to
avoid configurations that introduce unnecessary delays in transmission time. This is especially
important in the case of Firewall protection systems or VPN (Virtual Private Network) devices.
See Appendix A5
Optimising Performance: for a discussion of methods for optimising
communications.
