3.1.1 H.323 Version 2 Networks
The H.323 Version 2 standard is an important step toward the standardization of
equipment and software used in IP telephony. All BV1250 units are 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 Oki BV1250 units play 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, BV1250 compliance helps to
insure that:
•
All equipment 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.
•
As technological advancements occur, there is an easy upgrade path
while maintaining upward and downward compatibility with an
existing infrastructure.
•
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
minimized.
•
End-point terminals with differing capabilities (data, audio, and video)
can interact.
