Operation Manual

Configuring ISDN Call Destinations 123
Setting this timeout value to zero disables the Inactivity Timeout
facility.
If you disable the Inactivity Timeout, keep in mind that the ISDN line is
maintained physically from the first set up to the final clear down,
whether data is transferred or not. This means that charges accrue for
this whole period!!! Therefore, never set the Inactivity Timeout to "0" if
standard circuit-switched lines are used.
Please keep the following in mind: if the physical ISDN connection is
cleared by the Inactivity Timeout, the interface of the ISDN-Controller
maintains the logical connection and thus rejects all incoming calls from
any other remote sites (except when Remote Node Usage is set to On
Demand Interface Reservation). This means that if a different site tries
to establish an ISDN connection to that interface, the call will be
switched through by the local exchange, but the ISDN-Controller will
disconnect this incoming call and reject establishment of the logical
connection to this interface, since it is already in use.
12. Check the Self-Learning Timeout .
The Self-Learning Timeout automatically adjusts the Inactivity
Timeout for outgoing connections to different charge intervals
over the day. To calculate the appropriate timeout value, the
intervals between two charging pulses sent by the PTT are
measured.
To use the Self-Learning Timeout, the following requirements
must be met:
- Advice On Charge During Call (AOCD) must be activated at
your ISDN access
- the connection charges must be counted during the ISDN
connection and not only at the end of the connection.
Default: Disabled
Options: Enabled, Disabled
When the Self-Learning Timeout is enabled, the NetWare Multi-
Protocol Router for ISDN sets the Inactivity Timeout to one
charge interval minus two seconds. The new value is displayed
on the system console as "Calculated Self-Learning
Timeout <x>" when
