Changing Data Call Parameters 71 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. Understanding Data Call The Data Call Parameters window, shown in Figure 42, contains the following Parameters fields. Figure 42 Data Call Parameters Window Minimum Call Duration The minimum call duration is the minimum length of a call that must be satisfied before an inactivity timer can begin. The default for the minimum call duration is two minutes. Disconnecting an Automatic Data Call An automatic data call is made by the LAN Modem automatically due to activity on the LAN; an example would be a user launching his or her Web browser. 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

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.
Understanding Data Call
Parameters
The Data Call Parameters window, shown in Figure 42, contains the following
fields.
Figure 42
Data Call Parameters Window
Minimum Call Duration
The minimum call duration is the minimum length of a call that must be satisfied
before an inactivity timer can begin. The default for the minimum call duration is
two minutes.
Disconnecting an Automatic Data Call
An automatic data call is made by the LAN Modem automatically due to activity
on the LAN; an example would be a user launching his or her Web browser.
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
