Version 2 Networks - Panasonic KX-TDA0480 Installation Manual

2.1.1 H.323 Version 2 Networks
The H.323 Version 2 standard is an important step toward the standardisation of equipment and
software used in IP telephony. The KX-TDA0480 is compliant with the standards set forth
under the H.323 specifications.
The sample network used throughout this document is configured as H.323 and examples of
the parameters needed for network configuration are provided. Below is a brief discussion of
the H.323 standard and the role the KX-TDA0480 plays in the scheme of things.
H.323 Network Overview
H.323 is a device-independent, comprehensive set of multimedia communications standards
set forth by the International Telecommunications Unit (ITU). Among others issues, H.323 sets
forth standards for multimedia communications over IP-based Local Area Networks (LANs)
and Wide Area Networks (WANs) and for end-point (terminal) devices which interact across
the networks.
When implemented within an H.323 network, the KX-TDA0480 compliance helps to insure
that:
• The KX-TDA0480 is interoperable with other H.323 compliant devices, irrespective of
manufacturer.
• Communications between various networks (LAN and WAN), and between end-point
devices (terminals), is as seamless as possible.
• The impact of high network loads caused by bandwidth intensive applications such as video
and telephony applications, are more easily handled through H.323 bandwidth
management.
• The effects of variable LAN latency inherent in various networks are minimised.
• End-point terminals with differing capabilities (data, audio, and video) can interact.
The H.323 standard sets forth four major components that participate in an H.323
"conference".
