PPP Dial-up over ISDN 334
SmartWare Software Configuration Guide 30 • PPP configuration
• If an additional link (when using multi-link PPP) was up and is accidentally disconnected, we retry to
establish it after 5 seconds.
• If an additional link (when using multi-link PPP) could not be established because of call-signaling prob-
lems (e.g. no ISDN CONNECT received), the dialer retries the same destination again after 10 seconds.
• If an additional link (when using multi-link PPP) could be established (e.g. ISDN CONNECT received),
and therefore you probably have to pay for the connection, but if the PPP negotiation failed, the dialer does
not start another retry. It does not try to establish further links until the whole multi-link bundle is torn
down.
Use the following commands to configure the recovery strategy:
Mode: context cs/interface dialer
Create inbound destinations
You can also create inbound destinations. Inbound destinations can be used for dial-in connections. In that
case the call-router must be configured to route certain calls (e.g. calls with information transfer capability of
unrestricted-digital) to the dialer interface.
If you want two devices to be symmetrically connected, each being able to establish a dial-on-demand connec-
tion to the other, you have to create an outbound and an inbound destination with the same configuration
parameters.
Step Command Purpose
1 [name] (if-dialer)[dialer]#[no] recovery ini-
tial-link on-signaling-failure <timeout>
Configures the recovery timeout from a call-
signaling failure of the first link of a multi-link
bundle. The default value is 30 seconds.
2 [name] (if-dialer)[dialer]#[no] recovery ini-
tial-link on-network-error <timeout>
Configures the recovery timeout from a net-
work-establishment error (e.g. a PPP negotia-
tion problem) of the first link of a multi-link
bundle. The default is not to automatically
recover from this situation. The operation has
to execute the reset command manually in this
case.
3 [name] (if-dialer)[dialer]#[no] recovery
additional-link if-already-up <timeout>
Configures the recovery timeout from a link
teardown after the link was already up. The
default value is 5 seconds.
4 [name] (if-dialer)[dialer]#[no] recovery
additional-link on-signaling-failure
<timeout>
Configures the recovery timeout from a call-
signaling failure of an additional link of a
multi-link bundle. The default value is 10 sec-
onds.
5 [name] (if-dialer)[dialer]#[no] recovery
additional-link on-network-error <time-
out>
Configures the recovery timeout from a net-
work-establishment error (e.g. a PPP negotia-
tion problem) of an additional link of a multi-
link bundle. The default is not to automatically
recover from this situation. The bundle will
drain out of links. When all links of the bundle
are down, the dialer recovers from this situa-
tion without a manual intervention.
