Changing Data Call
Parameters
This section describes how to change the default settings for the data call
parameters. The data call parameters consist of time-out values and a threshold
setting for bandwidth on demand.
The timeout values are a useful means of using bandwidth efficiently and keeping
telephone usage and Internet access costs down. If there is no activity on a call for
an amount of time you specify, the call is disconnected.
The threshold parameters also provide a useful means of using bandwidth
efficiently by automatically adding a second B channel only when there is enough
traffic to justify the extra bandwidth, and by automatically removing the second B
channel when one B channel is sufficient.

Parameters
