86 CHAPTER 7: ADVANCED CONFIGURATION
Timeout Values
Minimum Call Duration for outgoing calls. The minimum call duration is the
minimum length of time that a call must stay up before an inactivity timer can
begin. The default is two minutes.
Disconnecting an Outgoing Automatic Data Call. An automatic data call is
made by the LAN Modem whenever it detects activity on the LAN requiring a
remote connection; an example would be a user launching his or her 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
simultaneously with the minimum call duration. For example, if the minimum call
duration is set to two minutes, and the inactivity timer is set to 30 seconds, the call
will be connected for at least two minutes even if there has been no activity for 30
seconds or more. To prevent a data call from being disconnected due to inactivity,
enter 0 (note that you must then manually disconnect the call via the Manual
Calling screen). The default is seven minutes.
Disconnect an Outgoing 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 due to 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 two 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 due to inactivity, enter 0. The default is 15 minutes.
The Desktop Manager for Windows 95/98/2000 and NT is a useful tool for
manually controlling calls without requiring a Web browser. The Desktop Manager
is located on the Companion Programs CD ROM or it may be downloaded from
the LAN Modem Web site:

Delay Between Redial Attempts for a Manual Call. This field designates the
length of time in seconds to wait before redialing a manual call. Acceptable values
are between 4 and 240 seconds.
