Dynamic Data Bandwidth Allocation
Dynamic Bandwidth Allocation is a cost savings feature that helps you save
money by only using the second B-channel when it is need for data transfers,
and then dropping the second B-channel when it is not needed. Dynamic
Bandwidth Allocation works with TurboPPP to add or drop the second B-
channel automatically. Dynamic Bandwidth Allocation determines the need for
the second B-channel by measuring the amount of data sent or received during
a set period of time. These threshold and timer values are set in TurboPPP.
Important:
Dynamic Bandwidth Allocation is set on by default. To turn off
Dynamic Bandwidth Allocation, use
*D0=1
.
Controlling Dynamic Bandwidth Allocation in MLPPP
Use the following *D0 settings to control Dynamic Bandwidth Allocation:
To do this
Use this setting
Or this setting
Enable Dynamic Bandwidth
Allocation in MLPPP
(default).
*D0=0
S68.6=0
Disable Dynamic Bandwidth
Allocation in MLPPP
*D0=1
S68.6=1
Controlling Bandwidth Sample Time
Use the following settings to control the period of time your I-modem samples
the throughput in order to determine if the second link needs to be brought up
or down:

Example
If a second link should be
brought up
*D1=n, where n equals
1-255 five second units
*D1=2 (ten seconds)
If a second link should be
brought down
*D2=n, where n equals
1 -255 five second units
*D2=10 (50 seconds)
