2.30. gc_SetEvtMsk( )

All event masks set by the gc_SetEvtMsk( ) function, other than GCMSK_BLOCKED and GCMSK_UNBLOCKED, act on the entire trunk (board). If the mask is set on any time slot level device, the event mask for all time slot level line devices on that board will be set to the same value. Similarly, when an event mask is set to a particular value on a trunk level line device, then all time slot level devices connected to that trunk will have the same event mask value.

Note: ISDN does not support disabling GCEV_BLOCKED or GCEV_UNBLOCKED in the gc_SetEvtMsk( ) function

Table 13 shows the default values used by gc_SetEvtMsk( ) for ISDN.
