ISDN Router 50
Utilization Threshold (%)
Initially a call is activated on one B-channel. When bandwidth
utilization reaches the bandwidth threshold, the second B-channel is
activated (if the maximum links value has been set to 2). Both channels
are utilized until the bandwidth utilization drops below the threshold for
5 seconds, then the second channel is dropped.
⇒
Set a number from 0 to 100 in the field Utilization Threshold .
(The default is 50% utilization which means that the second channel will
connect immediately after the first channel connects.)
Bandwidth Management Direction
Bandwidth management can be applied to incoming, outgoing, or both
directions of traffic between the router and the remote site.
Select Input , Output, or Input and Output.
Enable Data Compression
Compression for the link is enabled by default.
⇒
However, if you experience compatibility problems, turn off data
compression.
Dial-Back Numbers
Dial-Back forces the local router to refuse an incoming call from the
remote router and dial the remote router back. This feature allows ISDN
phone charges to be billed to the local router. Check Chapter 6,
Advanced Configuration Features , for additional information.
⇒
Click OK to save all of the remote router’s dial settings.
Security Information
⇒
From the remote router menu screen select Security.
The Security window allows you to specify the type of authentication and
password required by the target router when communicating with the
remote router.
