Enter the address of the interface for this particular call destina-
tion.
The entry in this field must be identical with the Origination
Subaddress configured for the respective interface of the ISDN-
Controller at the opposite end of the link. Otherwise the call is
rejected and one charge unit is wasted.
11. Check the Inactivity Timeout .
Since charges accrue for the duration of a call whether data is
being transferred or not, this feature is essential for saving
connection charges.
The Inactivity Timeout deactivates an existing ISDN connection
physically if no data traffic is detected in either direction for the
specified period of time. This process is transparent to all
workstations linked over this ISDN connection, since the logical
(protocol specific) connection between both sites is maintained,
and the physical connection is automatically re-established
within 1 or 2 seconds, if data traffic is detected for the remote
site.
Default: 10 seconds
Options: 0 seconds to 59 min 59 sec (0=disabled);
Time-Controlled
You can either specify a fixed value for the Inactivity Timeout or
select Time-Controlled and configure different Inactivity Timeout
values for different times in the Time Restrictions menu (see Step
29). The latter is useful when you cannot use the Self-Learning
Timeout (for example Advice On Charge During Call not acti-
vated) and want to configure times at which the Inactivity
Timeout is changed to adapt it to the different day and night
tariffs of the ISDN network.
If you want to use a fixed Inactivity Timeout, set the value
appropriate for the call destination; i.e. take the meter clock
pulse valid for the current call destination and set the Inactivity
Timeout a little lower. Thus, the Inactivity Timeout will discon-
nect the ISDN connection physically shortly before the next
charge unit will be counted.
For information on the charge intervals, please contact your local PTT.
