6.12. TERM_BLK

The TERM_BLK data structure contains information regarding the application's response to the CCEV_TERM_REGISTER event. The response is sent using the cc_TermRegisterResponse( ) function.

The structure is defined as follows:

typedef struct  
{  
   DLINK data_link;  
   byte  ack_type;  
   union  
   {  
      byte cause_value; /* Cause Value if ack type is ISDN_ERROR */  
      struct   
      {  
         byte usid;  
         byte tid;  
         byte interpreter;  
      } uspid;  
   } ack_info;  
} TERM_BLK, *TERM_BLK_PTR;  
/* where DATA_LINK contains the following structure */  
typedef struct   
{  
   byte  sapi;  
   byte  ces;  
} DLINK, *DLINK_PTR;

Table 41. TERM_BLK Field Descriptions

Field	Description
data_link	The DLINK data structure; see Section 6.4. DLINK.
ack_type	The type of acknowledgement to be passed to the firmware. The settings are:   ISDN_OK - to send a Positive acknowledgment   ISDN_ERROR - to send a Negative acknowledgment
cause_value	The Cause Value defined in isdncmd.h. (For a listing of Cause Values, see Section 7.2.1. Cause/Error Codes from the ISDN Firmware.)
usid	User Service Identifier. The range is 01 -- FF. 00 signifies default.
tid	Terminal Identifier. The range is 01 -- 63. 00 signifies that the firmware is to provide a default.
interpreter	Specifies how the usid and tid values are to be interpreted. Possible value settings are:   0 = terminal is selected when it matches both the USID and TID   1 = terminal is selected when it matches the USID but not the TID
