1.11.2. Alarm Handling for Springware Boards

As described in the Global Call API Library Reference, the GCEV_BLOCKED and GCEV_UNBLOCKED events indicate that an alarm condition has occurred or has been cleared, respectively. These events are generated on every opened line device associated with the trunk on which the alarm occurs, if the event is enabled. These events are enabled by default. The application may disable and enable the events by using the gc_SetEvtMsk( ) function.

If enabling or disabling these events from the board using ISDN, setting the event mask on any line device that represents a time slot will result in setting the mask to the same value on all time slot level line devices on the same trunk. Additionally, setting the event mask on a line device that represents the board will have the same effect (that is, it will set the mask for all time slot level line devices on that trunk).

Alarm notification can be configured for time slot devices using the Global Call Alarm Management System (GCAMS). The set of Global Call functions that comprise the GCAMS interface for alarm management is supported. See the Global Call API Programming Guide for more information on GCAMS and the Global Call API Library Reference for more information on the GCAMS functions. Alarm notification only occurs on the first alarm on and the last alarm off.

The following list shows the alarms that are supported for ISDN on E-1 for Springware boards. The dagger symbol () next to an alarm name indicates that the alarm is blocking by default. The default can be changed using gc_SetAlarmConfiguration( ).

The following list shows the alarms that are supported for ISDN on T-1 for Springware boards. The dagger symbol () next to an alarm name indicates that the alarm is blocking by default. The default can be changed using gc_SetAlarmConfiguration( ).
