5.3 Fieldgate with analog modem
The telephone connection must be set up in both the Fieldgate and the host computer, whereby the
latter must be equipped with an analog modem. There are two basic use cases:
• The user dials into the Fieldgate and views the required information.
In this case, only the modem needs to be set-up
• The Fieldgate is prompted to call back the user via an Internet Service Provider.
In this case both the modem and the ISP dial-in parameters must be set up. In addition you
will have to set up the mail, and if necessary, time server parameters, see chap. 5.5.
For additional information on Internet Service Providers, see chap. 12.2.
