Figure 47 Data Call Parameters Window
Minimum Call Duration
The minimum call duration is the minimum length of a call that is measured and must be satisfied before a call is disconnected. The default for the minimum call duration is 2 minutes.
Disconnecting an Automatic Data Call
An automatic data call is a call made automatically by the LAN Modem because of activity on the LAN to the WAN. 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 because of inactivity. The inactivity timer runs simultaneously with the minimum call duration. For example, if the minimum call duration is set to 2 minutes and the inactivity timer is set to 30 seconds, the call will be connected for at least 2 minutes even if there has been no activity for
30 seconds or more. To prevent a data call from being disconnected because of inactivity, enter 0 (note that you must then manually disconnect the call via the Manual Calling screen). The default is 30 seconds.
Disconnecting a Manual Data Call
A manual call is established using the Manual Calling option from the LAN Modem’s main page. You can define the amount of time the LAN Modem should wait before disconnecting this type of data call because of inactivity. This inactivity timer is activated once the minimum call duration is satisfied and no further activity is detected. For example, if the minimum call duration is set to 2 minutes and the inactivity timer is set to 15 minutes, the call will be connected for at least 15 minutes. To prevent a manual call from being disconnected because of inactivity, enter 0. The default is 15 minutes.
