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.
