Changing Data Call This section describes how to change the default settings for the data call

Parametersparameters. 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.
