Additional connection options

You may also enable or disable further options in the wizard, depending on whether or not they are supported by your Internet provider:

Time-based billing or flat rate – select the accounting model used by your Internet provider.

When using time-based billing, you can set the LANCOM to automat- ically close existing connections if no data has been transferred within a specified time (the so-called idle time).

In addition, you can activate a line monitor that identifies inactive remote stations faster and therefore can close the connection before the idle time has elapsed.

Active line monitoring can also be used with flat rate billing to con- tinuously check the function of the remote station.

You also have the option of keeping flat rate connections alive if required. Dropped connections are then automatically re-established.

Dynamic channel bundling (ISDN only)

if required, the second ISDN B-channel will automatically be bundled to the connection. This doubles the available bandwidth; it may also double your connect charges as well, however. What's more, your ISDN connection will be busy in this case, with all other incoming and outgoing calls being rejected.

Data compression

this permits an additional increase in data throughput.
