In addition you can use the Wizard to activate or deactivate additional options
(if supported by your Internet provider):
Creating a backup connection to the Internet
The most common utilization of the backup solution is to provide an auxiliary
Internet connection. When setting up an Internet connection, an the addi-
tional option is to create a second connection to the Internet via an alternative
WAN interface. If the primary Internet access is set up to operate via the ADSL
interface, you can set up your backup connection to operate via UMTS or
ISDN.

Billing by time or flatrate – select the method by which you are billed by
your Internet provider.
In case of billing by time, you can set the LANCOM to cut connections
automatically if no data flows for a certain time (the hold time).
You can also set up line polling that detects inactive remote sites very
quickly and, in such cases, can close the connection before the hold
time expires.
In case of flatrate billing you can also set up line polling to monitor
the function of the remote site.
Apart from that you can opt to keep flatrate connections permanently
active ("keep-alive"). In case a connection should fail, it is re-estab-
lished automatically.
When configuring the backup connection you can set up an alterna-
tive provider, if available. This allows you not only to overcome prob-
lems with the physical line, but also problems in your provider's own
network as well.
