L2W-323 Gateway and VIU-323

The L2W-323 Gateway enables H.320 room systems connected to the LAN via a VIU-323
Video Interface Unit to communicate with other H.320 terminals on a circuit-switched
public network.
The VIU-323 acts as a terminal adapter for the H.320 room system connecting it to the
LAN, and the L2W-323 Gateway treats the VIU-323 as any H.323 endpoint, making it
possible for the H.320 room system to communicate with terminals on the ISDN network.
