Voice Over IP Addressing
The KX-TDA0480 relies on static IP addressing for communications between network
devices. This means that networks in which all addressing is allocated on the basis of dynamic
IP addressing (DHCP/BOOTP) are incompatible with the KX-TDA0480 technology. Hybrid
systems capable of employing both static and dynamic addressing are capable of employing
the KX-TDA0480 technology.
All IP addressing must conform to Internet Protocol addressing standards. The diagram below
illustrates IP addressing for the sample network used in this document.
Sample network configuration
Overall
Subnetting
IP addressing defines subnetting. Each network location has a subnet mask address that helps
to define which digits of an IP address are used for the network address and the host address.
In this case the sample network, the subnet address is the KX-TDA0480 default,
255.255.255.0. The subnet mask addresses for various networks may differ from the default
subnets. In the case of the Internet, the subnet mask address will be provided by the regulating
agency or the IP address provider.
