Changing Data Call
Parameters
This section describes changing the data call parameter default settings. The data
call parameters consist of timeout values for both automatic calls and manual
calls.
The timeout values are a useful means of controlling bandwidth efficiently while
keeping telephone usage and Internet access costs down. If there is no network
activity on a call for a specified amount of time, then that call is automatically
disconnected.

Parameters
The Data Call Parameters window, shown in Figure 42, contains the following
fields.

Minimum Call Duration
The minimum call duration is the minimum length of a call that must be satisfied

Because the parameters for the call, such as the telephone number and user
name, have been previously defined, a call to an ISP, for example, may be
automatically and transparently launched with a click of your Web browser.
You can define the amount of time the LAN Modem should wait before
disconnecting this type of data call due to inactivity. The inactivity timer runs
