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.
୴
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.
୴
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)
୴
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 (ISDN only)
୴
this permits an additional increase in data throughput.
