Operation Manual

Physical Inactivity Timeout
22 NetWAYS/ISDN – 3 Remote Access with NetWAYS/ISDN
automatically dials up the connection. Thanks to the fast
dial-up times in ISDN (1 to 2 seconds), this operation is hard-
ly noticeable.
The time before the idle physical connection is cleared down
(the inactivity timeout) can be controlled either as a fixed de-
lay setting, or by charge profiles.
Inactivity Timeout
If no data communication takes place during a specified de-
lay, the ISDN connection between the NetWAYS/ISDN com-
puter and the remote network is cleared down. This delay
can be determined in two ways:
Statically
You can specify a fixed delay before an idle connection
is cleared down.
Using the self-configuring timer
NetWAYS/ISDN can adjust the timeout delay itself. In
this case the delay before the idle physical connection
is cleared down is not fixed. Instead, NetWAYS/ISDN
sets the inactivity timeout based on the charge informa-
tion received from the ISDN line. The inactivity timeout
is then closely aligned to current charge interval. This
feature in NetWAYS/ISDN is called the “self-configuring
timer”.
Please note that, in order to use the “self-configuring timer”
feature, your ISDN line must provide charge information dur-
ing the connection. Have your ISDN provider enable this ser-
vice on your line. If your ISDN line is a PBX extension, the
PBX must also forward the charge information.
Inactivity Timeout Using a Charge Profile
NetWAYS/ISDN can use charge profiles to control how long it
waits before clearing down an idle physical connection. A
charge profile contains information about the length and
cost of connection charge intervals. These charge rates are
dependent on geographic dialing areas, and change with the
time of day.
