ISDN_CONNECT.ISDN_CONF(D7isdn)

ISDN_CONNECT.ISDN_CONF -- ISDN call set-up confirmation

Synopsis

   #include <sys/stream.h>
   #include <sys/mdi.h>
   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef struct isdn_connect_conf
   {
       isdnPLCI_t  plci;
       isdnInfo_t  info;
   } isdn_connect_conf_t;

Description

The ISDN_CONNECT.ISDN_CONF message consists of one M_PROTO(D7str) message block confirming the initiation of a call set-up request. This connection is assigned a PLCI (Physical Link Connection Identifier) that serves as an identifier in further processing. Errors are returned in the info parameter.

The connection is in the set-up phase once the ISDN_CONNECT.ISDN_CONF message has been issued. Subsequent successful switching is indicated by the ISDN_CONNECT_ACTIVE.ISDN_IND(D7isdn) message.

If an application has to identify the corresponding ISDN_CONNECT.ISDN_REQ(D7isdn) to this message, it can use the message number mechanism provided by the isdn_msg_hdr(D4isdn) structure.

Parameters

plci

Physical Link Connection Identifier; see isdnPLCI(D4isdn).
