bandwidth Configuration Bandwidth Setup and : Item selection or The Bandwidth Setup in VT640P divides the bandwidth into 5 levels: (in Kbps) 1. 128 2. 256 3. 384 4. 512 5. 638 Note that the bandwidth affects the quality of video transmission; a low bandwidth setting that leaves too much bandwidth unused is a waste of connection resources, and a high bandwidth setting that exceeds the bandwidth that is available will jam the transmission and the video quality will be far lower than expected. To choose the bandwidth that makes the most effective use of your connection, read the following carefully. For home users: Set the bandwidth you wish to be used by the VT640P. It should not be more than the bandwidth of your type of connection. Note for ADSL users: The upload and download rates of VT640P are the same. ADSL is a type of connection whose download rate is not the same as the upload rate. ADSL users are advised to set the lower rate of the two as the bandwidth to be used by VT640P. For business users: It is best to reserve a certain amount of bandwidth for videoconferencing on a LAN connection for the VT640P users to set its bandwidth accordingly. or OK OK and : Item selection If you use PPPoE to connect to Internet, please do not set the bandwidth to higher than 384K.
