Note: The default behavior also applies if the Initial Alarm State parameter is not used. Behavior
is the same in both ISDN and CAS environments.
For more detailed information about configuring the Initial Alarm State parameter, see
Section 1.73.2, “Configuring the Software”, on page 257.
The Initial Alarm State parameter setting applies only upon board initialization. After the
initial alarm state is cleared (by gc_OpenEx( ) or gc_Open( )), trunks do not return to the
initial alarm state unless you restart the board. Stopping the board or unloading the
application does not return a board to its initial alarm state.
Note: An RAI alarm could result from a response to a loss of sync from the network side. If the
Initial Alarm State parameter is set to 2, but a loss of sync (or similar condition) persists
even after the board is initialized and gc_OpenEx( ) or gc_Open( ) is invoked, the RAI will
continue to be transmitted until the network condition is cleared.
A board could transmit other alarms, as a response to a network condition, that are
unrelated to this parameter. Those alarms will persist until the network condition is
cleared.

Boards are provided in media loads. A media
load consists of a configuration file set (PCD, FCD, and CONFIG files) and the associated
firmware that is downloaded to the board. See the Dialogic

Configuration Guide for more information about media loads.
In order to use the Initial Alarm State parameter, it must be manually added to the
CONFIG file that was selected for your board. The hexadecimal parameter number is
0x1626, and must be added in the [lineAdmin] section for each trunk. For example:
[lineAdmin.1]
SetParm=0x1626,1 ! InitialAlarmState (None=0, AIS=1, RAI=2)
[lineAdmin.2]
SetParm=0x1626,1 ! InitialAlarmState (None=0, AIS=1, RAI=2)
[lineAdmin.3]
SetParm=0x1626,1 ! InitialAlarmState (None=0, AIS=1, RAI=2)
[lineAdmin.4]
SetParm=0x1626,1 ! InitialAlarmState (None=0, AIS=1, RAI=2)
Note: The lineAdmin section for each trunk can specify its own trunk preconditioning.
Value Description
0 Default - No alarm is transmitted on the trunk; all trunk time slots signal
Out of Service.
1 TransmitAIS - An Alarm Indication Signal (AIS) alarm is transmitted on
the trunk.
2 TransmitRAI - A Remote Alarm Indication (RAI) alarm is transmitted on
the trunk.
