Dynamic Bandwidth—Specify use of dynamic bandwidth
allocation. The ViewStation EX system 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.
