11.1.6 DL_CONNECT_CON--Acknowledge DL_CONNECT_REQ

Positively acknowledges a previous DL_CONNECT_REQ primitive. Is sent upstream when a UA frame arrives to ack a previously sent SABME or SABM frame. This message consists of one M_PROTO message block containing the following structure:

typedef struct {
        t_uscalar_t     dl_primitive;           /* DL_CONNECT_CON */
        t_uscalar_t     dl_resp_addr_length;    /* responder's address len */
        t_uscalar_t     dl_resp_addr_offset;    /* offset from start of block */
        t_uscalar_t     dl_qos_length;          /* length of qos structure */
        t_uscalar_t     dl_qos_offset;          /* offset from start of block */
        t_uscalar_t     dl_growth;              /* set to zero */
} dl_connect_con_t;

The members of the dl_connect_con_t structure are:

Table 11-13 Members of the dl_connect_con_t structure

Member 

Description 

dl_primitive

Should be set to the name of this primitive. 

dl_resp_addr_length

The length of the DLSAP. This is 7 when working with LLC2 and 0 or 21 when working with LAPB. 

dl_resp_addr_offset

Offset to the responder (destination) address, stored in struct llc_dladdr or struct pstnformat format.

dl_qos_length

Always set to 0. 

dl_qos_offset

Always set to 0.
