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.

this function.
