The Onlan 323 Product Series - RADVision VIU-323 User Manual

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.
and the translate between the H.323 and the

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.
