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 Router to
automatically close existing connections if no data has been trans-
ferred 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.
