2.1 Basic Configuration Overview
The KX-TDA0480 is an H.323 Version 2 compliant Internet Voice Gateway card. Units are
designed to provide voice and fax transmission over an IP network, permitting the creation of
voice/fax networks over any IP compatible intranet and Internet.
IP-to-telephone number translation can be managed using H.323 Gatekeeper functions or the
KX-TDA0480's internal DNS functions.
A basic configuration is shown in Figure "Basic network configuration".
A few conditions must be met for the KX-TDA0480 installation.
• The KX-TDA0480 must be connected to the LAN using an Ethernet interface and must
be connected to the WAN (e.g., IP network) using a router.
• Only one IP network (Internet, Intranet, and VPN) can be used to interconnect
communicating devices.
• The KX-TDA0480 requires that the network used support static IP addressing.
Basic network configuration
Static addressing means that the IP addresses allocated to various devices in the network are
represented by fixed values. In some network applications, particularly large ones, addresses
are sometimes dynamically allocated (DHCP/BOOTP). When this is the case, a block of IP
addresses must be allocated for static assignment for the KX-TDA0480.
