5.9. TERM_BLK

When using DM3 boards, the TERM_BLK data structure is not supported.

When using Springware boards, the TERM_BLK data structure contains information regarding the application's response to the GCEV_SERVICERESP event. The response is sent using the GCEV_SERVICERESP( ) 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 49. TERM_BLK Field Descriptions

Field	Description
data_link	The DLINK data structure; see Section 5.5, 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 Table 33, Cause Values.)
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
