Installation
29
To configure the modem parameters, click the Modem tab, and
then select from the combo box the modem you want to
configure. Following is a description of all configurable parameters
and their meaning (see Figure 9):
1. In the Dial section, you can configure either Tone (default) or
Pulse dialling. Most networks use tone dialling, but if in
doubt, ask your telephone provider.
2. If required, enter a Dialing prefix; this is mostly needed when
your gateway is connected to a private telephone exchange
(e.g. a leading “0” before dialing).
3. The Advanced options section allows you to change:
a. The Initialization command: the default should be
sufficient for most situations; however, you may need to
add other modem commands depending on your
particular environment. For more details consult the AT
command set specification.
Note: If you have a “Worldmodem” built-in your gateway, then
remove the “%TCB” command from the initialization
command. The information on your built-in modem is
provided in a leaflet included in the A840 package. In case
of doubt, please consult your dealer.
