202 NetWare MultiProtocol Router for ISDN 3.1 Installation and ISDN Configuration Guide
Situation
Router A:
Interface 1: Outbound Call Processing: Disabled
Router B:
Call destination
for Router A: Inactivity Timeout
≠ Disconnect Timeout
- Router B calls Router A.
Consequence
Router A is not able to perform outgoing calls, because Outbound Call Processing is disabled on the
interface-level. When the connection is idle for the period specified for Inactivity Timeout, it is discon-
nected physically, but not logically. The logical connection is only cleared when the Disconnect Timeout
expires. If, in the meantime, Router A has data packets to be transferred to Router B, it is unable to set
up the physical connection to Router B.
When Outbound Call Processing is disabled on an interface, Inactivity
Timeout and Disconnect Timeout should be set to the same value to prevent
the router from trying to set up the physical connection after an inactivity
timeout.
Inbound Call Processing and Timeout Mechanisms
The following example shows what happens when Inbound Call
Processing is disabled on Router A, and Router B tries to set up the
physical connection after an Inactivity Timeout:
Situation
Router A:
Interface 1: Inbound Call Processing: Disabled
Call destination
for Router B: Inactivity Timeout
≠ Disconnect Timeout
- Router A calls Router B.
Consequence
When the Inactivity Timeout expires, the ISDN connection can be set up again from either site. If Router
B tries to set up the ISDN connection, Router A rejects the call since Inbound Call Processing is set to
Disabled.
