Useful Information on Internet Access
Configuration Examples
the browser. Access from a stand-alone PC via an online service differs from Internet access via the T-Comfort
930 DSL 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 T-Comfort
930 DSL automatically releases the connection to the Internet after a certain, specifiable duration.
■
It is possible to call up Web pages simultaneously from several workstations.
■
The T-Comfort 930 DSL 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 T-Comfort 930 DSL you can set up
one or more e-mail accounts for every user account configured on the T-Comfort 930 DSL. These e-mail
accounts are then checked at regular intervals.
If there are new e-mails in an e-mail account, and the T-Comfort 930 DSL has been configured for this
function, the user specified in the T-Comfort 930 DSL user account is notified of the new e-mail on his system
terminal. T-Comfort 730/830 DSL system telephones can also display information such as the sender or the
subject of the e-mail.
NAT
Network address translation (NAT) is activated on accessing the Internet (ISP). You require this feature in
order to translate internal IP addresses to valid external IP addresses. This has three important consequences
for Internet access:
■
Several workstations can share a single Internet access. You do not require a LAN access, only a single
account with the Internet service provider.
