Placing Calls
You can place calls from your computer through the ISDN LAN Modem to a
remote location either automatically by using one of the service provider
connections you set up or manually by entering the telephone number of the
destination.

Placing a Call
Automatically
To place a call using one of the service provider connections you set up, simply
launch the application. For example, if an ISP was configured, simply launch your
Web browser on your computer to connect to the default location configured in
your Web browser.
Telephone Number Selection for Data Calls
When you place a data call, the ISDN LAN Modem tries to use the second
telephone number assigned to your ISDN line in order to leave the first telephone
number free for voice calls. In many instances when voice services are added to an
ISDN line, they are added only to the first telephone number and not the second
telephone number. Because of this, the ISDN LAN Modem tries to use the second
telephone number, when available, for data calls.
Call Routing Among Service Providers
The ISDN LAN Modem automatically calls the first configured service provider. If
you configure a second remote connection, such as an additional ISP, and want to
use that second profile for an automatic data call, do the following.
1
Access the ISDN LAN Modem’s configuration main page.
2
Choose the Workstation graphic.
3
Select your computer.
4
Associate only the Service Provider that you want to use.
