Mediant 500 E-SBC
Parameter Description
physical trunks pertaining to that Trunk Group are set to the Busy-
Out condition. Each trunk uses the proper Out-Of-Service method
according to the selected ISDN/CAS variant.

Digital: For configuring the method for taking trunks/channels out-
of-service, see the DigitalOOSBehaviorForTrunk_x parameter for
per trunk or the DigitalOOSBehavior parameter for all trunks.
Web/EMS: Graceful Busy
Out Timeout [sec]
CLI: graceful-bsy-out-t-out
[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 (Serving Trunk Group), but maintains
currently active calls for this user-defined timeout. Once this timeout
elapses, the device terminates currently active calls and takes the
trunk out of service (sending the PSTN busy-out signal). Trunks on
which no calls are active are immediately taken out of service
regardless of the timeout.
The parameter is applicable to the locking of Trunk Groups feature 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.

For configuring the method for taking trunks/channels out-of-
service, see the DigitalOOSBehaviorForTrunk_x parameter for per
trunk or the DigitalOOSBehavior parameter for all trunks.
Web: Digital Out-Of-Service
Behavior
EMS: Digital OOS Behavior
For Trunk Value
CLI: dig-oos-behavior
[DigitalOOSBehaviorForTru
nk_x] Defines the method for setting digital trunks to out-of-service state. The
parameter is defined per trunk. The parameter is applicable to the
Busy Out feature (see the EnableBusyOut parameter) and the
Lock/Unlock per Trunk Group feature performed in the Trunk Group
Settings table of the Web interface.

[-1] Not Configured = (Default) Use the settings of the
DigitalOOSBehavior parameter ("global" parameter that applies to
all trunks).

[0] Default =

ISDN: Sends ISDN Service messages to indicate out-of-service
or in-service state for ISDN variants that support Service
messages. For ISDN variants that do not support Service
messages, the device sends an Alarm Indication Signal (AIS)
alarm.

CAS: Sends an Alarm Indication Signal (AIS) alarm.

[1] Service = (Applicable only to T1 ISDN variants that support this
method) Sends ISDN Service messages indicating out-of-service or
in-service state.

Graceful out-of-service disabled: The device rejects new
incoming calls and immediately takes all channels (idle and
busy) out-of-service, by sending Service messages on the B-
channels.

Graceful out-of-service enabled:
- Fully configured trunk (all channels): The device rejects new
incoming calls. If at least one busy channel exists during the
graceful period, the device immediately takes all idle channels
out-of-service, but sends out-of-service Service messages to
the B-channels only when all channels are idle.
- Partially configured trunk (only some channels configured):
The device rejects new incoming calls and places all channels
