ISDN_CONNECT_B3_ACTIVE.ISDN_IND(D7isdn)

ISDN_CONNECT_B3_ACTIVE.ISDN_IND -- ISDN B channel logical connection indication

Synopsis

   #include <sys/stream.h>
   #include <sys/mdi.h>
   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef struct isdn_connect_b3_active_ind
   {
       isdnNCCI_t      ncci;
       isdnNCPI_t      ncpi;
   } isdn_connect_b3_active_ind_t;

Description

The ISDN_CONNECT_B3_ACTIVE.ISDN_IND message consists of one M_PROTO(D7str) message block indicating the logical connection of a B channel. The ncci parameter identifies the connection; the ncpi parameter transfers additional protocol-dependent information. After this message is received, incoming data can be indicated to the application.

In the case of the T.30 protocol and outgoing calls, this message does not imply the successful training between both fax stations. This is to enable an application to send data to the ISDN driver without waiting for termination of training phase. If this training phase is not successful, corresponding indications will be given by the ISDN driver in the ISDN_DISCONNECT_B3.ISDN_IND(D7isdn) message.

Parameters

ncci: Network Control Connection Identifier; see isdnNCCI(D4isdn). The meaning of this parameter depends on the protocol used.
ncpi: Network Control Protocol Identifier; see isdnNCPI(D4isdn).
