Useful Information on Internet Access

Costs

The OpenCom 100 uses a router function to access the Internet, which means that it
automatically establishes an Internet connection when required and terminates the
connection after a certain period of time if no data are being transmitted.
Unfortunately, programmes other than those typically intended to access the Internet
(such as your browser or your e-mail software) may send out data packets which
cause an Internet connection to be established, even if these programmes are not
strictly Internet-associated applications.
Examples of such programmes are the Microsoft
multimedia programmes such as Realplayer
establish an Internet connection for automatic updates (the so-called "phone home
function").
It is therefore highly advisable to limit ISP access by specifying the maximum monthly
connection time under Connection time per month in the Network: WAN: [Pro-
vider] menu on the web console.

Using the Web

A Web browser not only enables you to use the OpenCom 100 Configurator from
every workstation computer but also to obtain a wealth of information from the
Internet. Simply enter the desired URL in the address field of the browser. Access from
a stand-alone PC via an online service differs from Internet access via the
OpenCom 100 in the following respects:
• When you request a Web page, dialling in results automatically. There is no display
of dialogues with manual confirmation of dialling in or hanging up.
• Requesting Web pages is not a connection-orientated service. When the Web
page has been loaded completely, the TCP/IP connection is cleared. If you do not
request further Web pages, the OpenCom 100 automatically releases the con-
nection to the Internet after a certain, specifiable duration.
• It is possible to call up Web pages simultaneously from several workstations.
• The OpenCom 100 can block access to certain Web pages by means of filter lists.
