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.
