When bandwidth on demand is enabled, a second channel will be brought up if traffic on the initial channel is
higher than the high Target Utility number for longer than the specified Add Persist value. Similarly, the
second channel will be dropped if the traffic level falls below the low Target Utility number for longer than
the Subtract Persist value.
The Target Utility specifies the line utilization range at which you want the Prestige to add or subtract
bandwidth. The range is 30 to 64 Kbps (kilobits per second). The parameters are separated by a ‘–’. For
example, ‘30–60’ means the add threshold is 30 Kbps and subtract threshold is 60 Kbps. The Prestige
performs bandwidth on demand only if it initiates the call. Addition and subtraction are based on the value
set in the BOD Calculation field. If this field is set to Transmit or Receive, then traffic in either direction
will be included to determine if a link should be added or dropped. Transmit will only use outgoing traffic
to make this determination and Receive will only use incoming traffic to make this determination.
If, after making the call to bring up a second channel, the second channel does not succeed in joining the
Multilink Protocol bundle (because the remote device does not recognize the second call as coming from the
same device), the Prestige will hang up the second call and continue with the first channel alone.
