ISDN_DISCONNECT_B3.ISDN_IND(D7isdn)

ISDN_DISCONNECT_B3.ISDN_IND -- ISDN logical connection disconnect indication

Synopsis

   #include <sys/stream.h>
   #include <sys/mdi.h>
   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef struct isdn_disconnect_b3_ind
   {
       isdnNCCI_t       ncci;
       isdnReason_B3_t  reason;
       isdnNCPI_t       ncpi;
   } isdn_disconnect_b3_ind_t;

Description

The ISDN_DISCONNECT_B3.ISDN_IND message consists of one M_PROTO(D7str) message block indicating that the logical connection identified by the ncci parameter has cleared. The reason parameter indicates whether the connection was cleared because of faulty protocol behavior. The ncpi parameter indicates additional protocol-dependent information (if available).

After this message, no other message concerning this NCCI (Network Control Connection Identifier) will be sent to the application. The application must answer this message with an ISDN_DISCONNECT_B3.ISDN_RESP(D7isdn) to free the resources allocated to the NCCI.

Parameters

ncci

Network Control Connection Identifier; see isdnNCCI(D4isdn).

reason

Disconnect reason codes; see isdnReason(D4isdn). Valid values are:

ISDN_REASONB3_OK: clearing according to protocol
ISDN_REASONB3_L1PERR: protocol error layer 1
ISDN_REASONB3_L2PERR: protocol error layer 2
ISDN_REASONB3_L3PERR: protocol error layer 3

ncpi

Network Control Protocol Information; see isdnNCPI(D4isdn). The value of this parameter depends on the protocol used.
