In order to avoid extra meaningless charges, it is suggested to the
subscribers of 64kbps to give the b40 command in the area of
Extra Settings, when they access the Internet.
The b0 command should be given only when your Internet access
rate is of 128kbps.
In case of a ML-PPP connection, the second B channel is added or subtracted according
to the transferred data rate (Bandwidth On Demand). When you use a B-channel and the
data rate exceeds a limit for a specific time period, the second B-channel will be added to
the connection. On the other hand, when both B-channels are used and the rate drops
below the limit for a specific time period, the second B-channel will be subtracted from the
connection. The limits of this rate for the addition / subtraction of B-channel, as well as the
time period for which the rate has to be above / below these limits, so that the B-channel
can be added / subtracted, are defined through AT Commands as described in the chapter
"AT COMMANDS".
