User's Manual 69. Configuration Parameters Reference
Parameter Description
Ethernet cable is disconnected).
 The Ethernet cable is connected, but the device is unable to
communicate with any host. For this scenario, the LAN Watchdog
feature must be activated (i.e., set the EnableLANWatchDog
parameter to 1).
 The device
can't communicate with the Proxy Sets (according to the
Proxy Keep-Alive mechanism) associated with the destination IP
Groups for matching routing rules in the Tel-to-
IP Routing table, and
no other alternative route exists to send the call.
 The IP Connectivity mechanism is enabled (see the
AltRoutingTel2IPEnable parameter) and there is no connectivity to
any destination IP address configured for matching routing rules in
the Tel-to-IP Routing table.
Note:
 If the AltRoutingTel2IPEnable parameter is enabled, the Busy Out
feature does not function with the Proxy Set keep-alive mechanism.
To use the Busy Out feature with the Proxy Set keep-alive
mechanism (for IP Groups), disable the AltRoutingTel2IPEnable
parameter.
 Analog:

The FXSOOSBehavior parameter determines the behavior of
the FXS endpoints when a Busy Out or Graceful Lock occurs.

FXO endpoints during Busy Out and Lock are inactive.

For additional optional behavior, see the LifeLineType
parameter.
 The Busy Out behavior depends on the PSTN protocol type.
 The Busy Out condition is also applied per Trunk Group. This
occurs if there is no connectivity to the Serving IP Group of a
specific Trunk Group (configured in the Trunk Group Settings tabl
e).
In such a scenario, all the physical trunks of the Trunk Group are
set to the Busy Out condition. Each trunk uses the out-of-service
method according to the ISDN variant.
 To configure the method for taking trunks/channels out-of-service,
see the DigitalOOSBehaviorForTrunk_x parameter for per trunk or
the DigitalOOSBehavior parameter for all trunks.
Graceful Busy Out Timeout

[GracefulBusyOutTimeout]
Defines the timeout interval (in seconds) for out-of-service graceful
shutdown mode for busy trunks (per trunk) if communication fails with
a Proxy server (or Proxy Set). In such a scenario, the device rejects
new calls from the PSTN (i.e., Serving Trunk Group), but maintains
currently active calls for this user-defined timeout. Once this timeout
elapses and there are still active calls, the device terminates the calls
and takes the trunk out-of-service (sending the PSTN busy-out signal).
Trunks without any active calls are immediately taken out-of-service
regardless of the timeout.
The parameter is applicable to the locking of Trunk Groups feature
(see Locking and Unlocking Trunk Groups on page 783) and the Busy
Out feature (see the EnableBusyOut parameter), where
trunks/channels are taken out-of-service.
The range is 0 to 3,600. The default is 0.
Note:
 The parameter is applicable only to digital interfaces.
