124 NetWare MultiProtocol Router for ISDN 3.1 Installation and ISDN Configuration Guide
- you set up a physical connection and the Self-Learning
Timeout has been calculated for the first time.
- the meter clock pulse changes and a new Self-Learning
Timeout is calculated.
For information on the influence of the Self-Learning Timeout
and the Disconnect Timeout, refer to Chapter 14, section "Opera-
tion of the Self-Learning Inactivity Timeout" in this Guide.
13. Check the Disconnect Timeout .
When the Inactivity Timeout clears down an idle connection
physically, a logical connection is maintained, which means that
all line management parameters negotiated during the initial call
set-up remain valid. The logical connection is controlled by the
Disconnect Timeout. When the Disconnect Timeout expires, the
logical network connection to the remote LAN is cleared as well.
The interfaces of the ISDN-Controllers at both the local and the
remote site are no longer reserved for this connection, and, if a
routing protocol is used, the remote LAN "vanishes". This may
be compared to pressing <Del> on an entry with the status "In-
Connected" or "Out-Connected" in the CALLMGR to clear
connections.
Default: 0 (=disabled)
Range: 0 seconds to 18 hours (0=disabled);
Same as Inactivity Timeout
Set the Disconnect Timeout value appropriate for the ISDN Call
Destination, if necessary.
The value for Disconnect Timeout must be higher than or equal
to the value for Inactivity Timeout. The difference between the
two is the period after which the connection is cleared logically
as well.
Example: Inactivity Timeout = 10 seconds; Disconnect
Timeout = 2 hours
-> The physical connection is cleared after 10
seconds whereas the interface is cleared logically
after 2 hours of inactivity. If data traffic is detected
within these 2 hours, the Inactivity Timeout and
Disconnect Timeout begin to count anew.
