Configuring Individual WAN Connections
Configuring MP, MP+ and BACP connections
specified in the Answer profile. The base channel count specifies the number of channels to
use to establish the connection, and this number of channels remains fixed for the whole
session. You can ignore the rest of the parameters discussed in this section.
Enabling BACP for MP Connections
Enable BACP in the Answer profile and in the Connection profile for each connection that
should use it. Open the PPP Options subprofile from the Answer profile and set BACP to Yes.
Open the Encaps Options subprofile from the Connection profile and set BACP to Yes. Both
sides of the connection must support BACP.
Specifying channel counts
In a Connection profile’s Encaps Options subprofile, the base channel count specifies the
number of channels to use to establish the call. Inc Ch Count and Dec Ch Count specify the
number of channels the connection can add and subtract at one time, respectively. You can also
specify a maximum and minimum number of channels that can be allocated to the call. For
additional information, see Parallel Dial in the MAX Reference.
Dynamic algorithm for calculating bandwidth requirements
In an Encaps Options subprofile, the Dyn Alg parameter specifies an algorithm for calculating
ALU during the period specified, in seconds, by the Sec History parameter. Figure 4-2 shows
how the available algorithms weight usage samples.
Figure 4-2. Algorithms for weighing bandwidth usage samples
Quadratic (the default) gives more weight to recent samples of bandwidth usage than to older
samples taken during the specified period. The weighting grows at a quadratic rate.
Linear gives more weight to recent samples of bandwidth usage than to older samples taken
during the specified period. The weighting grows at a linear rate.
Constant gives equal weight to all samples taken during the specified period.
Time period for calculating average line utilization
Sec History specifies a number of seconds to use as the basis for calculating ALU.
