DI-304/DI-304M ISDN Remote Router
Bandwidth On Demand (BOD) Setup
BOD stands for bandwidth-on-demand for Multiple Link PPP (ML-PPP or MP).
Click Call Control and PPP/MP Setup to see the following settings.
These parameters are activated when you set the Link Type to Dialup BOD.
Usually the ISDN will use one B channel to access the Internet or remote network
when you use the Dialup BOD link type. The router will use the parameters here to
make a decision on when to activate/drop the additional B channel. Note that cps
(characters-per-second) measures the total link utilization.
♦ High Water Mark and High Water Time – These parameters specify
the conditions under which the second channel will be activated. When
the utilization of the first connected channel goes over the High Water
Mark and past the High Water Time, the additional channel will be
activated. The link speed will then be 128kbps (two B channels).
♦ Low Water Mark and Low Water Time – These parameters specify the
conditions under which the second channel will be dropped. When the
utilization of two B channels is under the Low Water Mark and past the
High Water Time, the additional channel will be dropped. The link speed
will be 64kbps (one B channel).
Note: If you are not familiar with the operation of ISDN and ML-PPP, be wary of
changing the default values.
