acu_ss_reject extended data structure

If a stack or network error occurs when an attempt is made to invoke or activate a service, the acu_ss_reject substructure is returned in an ACU indication or confirmation message (such as ACU_FACILITY_IN or ACU_CLEAR_CO). The service header to this structure contains:

• The operation ID of the supplementary service (for example, ACU_OP_ID_CALL_DEFLECTION)

• OpType ACU_OP_TYPE_REJECT

The following is a listing of the acu_ss_reject extended data structure:

struct acu_ss_reject
{
  struct acu_ext_hdr ext_hdr;       /* Extension header                */
  struct acu_ss_hdr  ss_hdr;        /* Supplementary services header   */
  uchar              local_cause;   /* From SS_REJECT_LOCAL_ constants */
  uchar              network_cause; /* From SS_REJECT_NETWORK_constants*/
  pad6
};
 

The local_cause and network_cause fields in this structure indicate the cause for the rejection. The possible values for these fields are listed in the Constants for isdnacu.h section of this manual.
