Prestige 128IMH ISDN Modem/ Router/Hub
4-8 Remote Node Configuration
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.
The BOD configuration is through Menu 11.2 - Remote Node PPP Options.
