Web conferencing (PSOM): 20 kbps (minimum); 200 kbps (typical); 500 kbps (maximum) File Transfer: 20 kbps (minimum); 200 kbps (typical); 200 kbps (maximum) Application Sharing: 256 kbps (minimum); 1 Mbps (typical); 3.5 Mbps (maximum)Typical bandwidth values are measurements of typical activity levels under good network conditions (for example, with no forward error correction, or FEC). This value can be used for capacity planning to assess if a network is provisioned appropriately. The values are cumulative. For example, for a conference call with audio, Common Intermediate Format (CIF) video, and panoramic video, an appropriately provisioned network would provide a bandwidth speed of 585 Kbps (95+210+280=585 Kbps).
