Using the Web
A Web browser not only enables you to use the Forum 523/524
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 Forum 523/524 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 Forum 523/524 automatically
releases the connection to the Internet after a certain, specifiable duration.
●
It is possible to call up Web pages simultaneously from several worksta-
tions.
●
The Forum 523/524 can block access to certain Web pages by means of
filter lists.
One of the most important services in the Internet is e-mail. E-mails are
buffered in individual e-mail accounts on a mail server. Mail servers are
operated by ISPs for example. With the Forum 523/524 you can set up one or
more e-mail accounts for every user account configured on the Forum 523/
524. These e-mail accounts are then checked at regular intervals.
If there are new e-mails in an e-mail account, and the Forum 523/524 has
been configured for this function, the user specified in the Forum 523/524
user account is notified of the new e-mail on his system terminal.
Forum Phone and Forum Free system terminals can also display information
such as the sender or the subject of the e-mail.
