Dynamic Bandwidth—Specify use of dynamic bandwidth
allocation. The ViewStation FX and VS4000 dynamic bandwidth
function automatically finds the optimum line speed for a call.
If you experience excessive packet loss while in a call, the
Dynamic Bandwidth function decreases the line speed until
there is no packet loss. After some time with no packet loss, the
dynamic bandwidth function incrementally increases line speed
until packet loss occurs. At this point, the Dynamic Bandwidth
function lowers the line speed one increment to ensure minimal
packet loss with maximum throughput. This is supported in
calls with end points that also support Dynamic Bandwidth.
