Introducing the VIU-323
The VIU-323 is a self-contained terminal adapter that translates between H.320 and H.323
communications protocols. The VIU-323 connects your H.320 videoconferencing system
(“room system” or “group system”) to an IP network (LAN, Internet or intranet) and
provides complete end-to-end interoperability between the room system and all other H.323
devices on the network. By opening up your room system to the previously inaccessible
world of H.323 networking without losing any H.320 functionality, the VIU-323 preserves
and enhances your room system investment.

VIU-323 Physical Description
The VIU-323 is built in a low-profile unit designed to comfortably fit in the cabinet of your
H.320 videoconferencing system or in a 19-inch rack.
Front Panel
The VIU-323 front panel contains LEDs and an asynchronous RS-232 serial port that you
can connect to a PC or a modem. Use this port to run a terminal session for defining IP
addresses or running diagnostics.

Console Port
You can connect the RS-232 console (serial) port directly to a terminal or to a remote
terminal via modem for diagnostics, monitoring and configuration. The console port has a
female DB9 connector. For information on connecting this port, see “Connecting to the
Console Port” in Chapter 3, “Installing the VIU-323.”
Rear Panel
The VIU-323 rear panel contains one LAN port, two serial ports (to connect the VIU-323 to
the room station), and a power plug with an ON/OF switch.

The OnLAN 323 Product Series
The RADVision OnLAN 323 product series provides connectivity for multimedia
applications between IP based networks such as LANs, Intranets and the Internet and circuit
switched networks such as ISDN and PSTN. The OnLAN 323 product series consists of the
L2W-323P Gateway (PRI), L2W-323 Gateway (BRI and V.35), the MCU-323 Multipoint
Conference Unit, the VIU-323 Video Interface Unit and the NGK-100 Gatekeeper. These
“building blocks” allow users to communicate over different networks, products and
protocols.
The L2W-323 Gateway
H.320 protocols, allowing the exchange of voice, video and data between H.323 based
conferencing endpoints on IP networks and H.320-compliant endpoints on circuit switched
ISDN networks as well as Voice over IP (VoIP). Connecting to an ISDN PRI, BRI or V.35
interface, the L2W-323 Gateway provides connections at rates of 384 Kbps, 128 Kbps or 64
Kbps. In conjunction with the internal Gatekeeper, the L2W-323 and L2W-323P Gateways
operate as multimedia PBXs allowing internetwork calls, direct inward dialing and call
transfer.
The MCU-323 Multipoint Conference Unit
only or full multimedia multipoint conferences at rates ranging from 64 Kbps to 1.5 Mbps.
The MCU-323 also provides audio mixing (G.711 A/µ Law), video switching (H.261
CIF/QCIF, voice activated) and simple monitoring of conferences using a web browser.
The VIU-323 Video Interface Unit
Room Systems to IP networks without disrupting the current H.320 capabilities of the
Room System. The VIU-323 translates between the H.323 and H.320 video and audio
streams and respective communication protocols.
The H.323 Gatekeeper
Gateway and the MCU-323 Multipoint Conference Unit. It manages the H.323 network by
enabling address resolution, full call control and supplementary call services such as call
forward and transfer. The H.323 Gatekeeper can be disabled in the L2W-323 Gateway and
in the MCU-323 Multipoint Conference Unit, allowing you to use an external gatekeeper.
NGK-100 Gatekeeper
for production IP telephony and multimedia networks. With the NGK-100 network,
managers can define, control, optimize and manage multimedia conferencing or Voice over
IP calls. The NGK-100 Gatekeeper is H.323 Version 2 compliant.

Overview
An Introduction to H.323
H.323 is the globally accepted standard for audio/video/data communications over IP-based
networks. It specifically describes how multimedia communications occur between user
terminals, network equipment, and assorted services on Local and Wide Area Internet
Protocol (IP) networks.
What is the H.323 Standard
H.323 is an umbrella recommendation from the International Telecommunications Union
(ITU) that specifies real-time multimedia communications over Internet Protocol-compliant
networks. It defines new models of interaction for both point-to-point and multipoint
conferences. For example, H.323 specifies how gatekeepers can provide address translation
and bandwidth management and how gateways can connect terminals on the LAN to those
on the WAN.
H.323 Network Components
The H.323 specification defines a number of new network components that interoperate
with other standards-compliant endpoints and networks by virtue of an H.323/H.32X
gateway.
Following are the network components defined by the H.323 standard:
Terminals
communications. Most H.323 terminals are desktop computers running H.323 compliant
software. All terminals must support voice communications while video and data are
optional. However, if these other media are supported, H.323 specifies what modes of
operation are required so that all terminals supporting video and/or data can work
seamlessly together.
Gateways
conferencing endpoints on the IP network and other ITU-compliant terminals (for example,
H.320 room systems) on other circuit switched networks.
Gatekeepers
providing network administrators the ability to incorporate management and security
policies into the network. Although the H.323 recommendation describes the gatekeeper as
an optional component of a functional H.323 system in practice the gatekeeper is essential.
The H.323 gatekeeper is responsible for providing address translation between LAN aliases
and IP addresses, call control and routing, basic telephony services such as directory
services and PBX functions, H.323 traffic bandwidth usage control and total network usage
control and the implementation of overall system management and security policies.

An Introduction to H.323
Multipoint Controller Units (MCUs)
an optional multipoint processor or processors (MP). The MC is the conference controller.
The MC handles negotiation between all terminals to determine common capabilities and
controls conference resources such as multicasting. The MC does not deal directly with any
of the media streams. This is left to the MP, which does the mixing, switching, and other
processing of audio, video, and/or data bits.
Terminals, gateways and MCUs are also known as H.323 endpoints. The collection of all
terminals, gateways, and MCUs managed by a single gatekeeper comprise an H.323 Zone.
consists of a required multipoint controller (MC) and
Between H.323 and H.320
H.320 is the ITU standard for video conferencing over digital lines like ISDN. The standard
describes recommendations for both multipoint and point-to-point video conferencing over
circuit-switched networks (CSNs).
If you want your H.323 LAN endpoints to communicate with H.320 terminals within a LAN
segment, you need a VIU-323 to convert the H.320 to H.323 protocol.
If you want your H.323 LAN endpoints to communicate with H.320 terminals on circuit-
switched networks without actually connecting each LAN endpoint to an ISDN line, you
need a gateway that converts between these protocols.
