Notifies the application of a change in the state of a subsystem at a concerned signaling point (eventType of TCAP_EVENT_SSN_STATE):
typedef struct Tcap_Ssn_State_Event
{
U8 aSsn; /* affected subsystem number */
U8 status; /* new subsystem status */
U8 smi; /* subsystem multiplicity indicator */
U8 spare; /* spare for alignment */
U32 aPc; /* affected point code - future use */
U32 opc; /* originating point code */
} TcapSsnStateEvent;
The TcapSsnStateEvent structure contains the following fields:
Field |
Description |
aSsn |
Contains the affected subsystem number. Valid range is 0 - 255. |
status |
Represents the new status of the affected subsystem: 0x03 = SS_OOS Subsystem out of service 0x04 = SS_IS Subsystem in service |
smi |
Represents the subsystem multiplicity indicator, or the new status of the subsystem with respect to replication: 0x00 = SMI_UNKNOWN Multiplicity unknown 0x01 = SMI_SOLO Subsystem not replicated 0x02 = SMI_DUP Subsystem is replicated |
aPc |
Not currently available. Reserved for future use. |
opc |
Originating point code - used for multiple OPC support. |
