Some parameters of the NetWare MultiProtocol Router for ISDN
interfere with other parameters and can, in rare cases, lead to critical
situations. To help you avoid such situations, the following lists
dependencies between parameters and describes their consequences.
You should read through the following very carefully to avoid configuration
errors and high connection charges due to parameter inconsistencies!
Interdependencies with Call Processing
When Outbound Call Processing is disabled or COSO is set to "No
Dial-Out" for an ISDN interface, no outgoing calls, whether initial or
for underlying call set-ups after an inactivity timeout, are possible.
This has the following consequences:
- The logical connection is terminated when the local router at-
tempts to perform an underlying call set-up.
- The Self-Learning Timeout makes no sense, since no outgoing calls
are allowed.
- A Recall Request by a remote NetWAYS/ISDN client is denied.
- Channel On Demand cannot be used on the respective ISDN-
Controller in the local router, since the interface cannot activate a
second data channel when needed.
Outbound Call Processing and Timeout Mechanisms
The following example shows what happens when Outbound Call
Processing is disabled on an interface of Router A and Inactivity
Timeout and Disconnect Timeout on Router B are not set to the same
value, i.e. the physical and logical connection are not terminated at
the same time:
