Another possible configuration is shown in Figure 1-2 . As shown, two terminals are connected in the Bridging configuration via a network, and the VT320 analyzes the data streams from each of the terminals. In the Bridging mode, the VT320 monitors the full duplex connection between the two terminals. The H.261 video output is analyzed from either of the terminals as well as service channel information from both terminals. Bride Monitor Receives Channel 1 and Channel 2 Data Streams from the DCE Terminal or from the DTE Terminal.
Protocol is received from both sides of the bridge.
Audio and video are only saved from one side of the bridge. The VT320 can replace a terminal, as shown in Figure 1-3 . The VT320 will report any errors in the received bit stream. The nature and frequency of errors can be used to determine whether faults are in the remote terminal, the local terminal, or the network. The VT320 can be used in a endless variety of equipment and network configurations.
