ISDN_CONNECT_B3.ISDN_CONF -- ISDN logical connection set-up confirmation

Synopsis

   #include <sys/stream.h>
   #include <sys/mdi.h>
   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef struct isdn_connect_b3_conf
   {
       isdnNCCI_t      ncci;
       isdnInfo_t      info;
   } isdn_connect_b3_conf_t;

Description

The ISDN_CONNECT_B3.ISDN_CONF message consists of one M_PROTO(D7str) message block confirming the initiation of a logical connection set-up. The connection is assigned a Network Control Connection Identifier, which subsequently identifies this logical connection. Status codes are supplied in the info parameter.

The connection is the set-up phase at this point. The successful set-up will be indicated by an ISDN_CONNECT_B3_ACTIVE.ISDN_IND(D7isdn) message.

Parameters

ncci

Network Control Connection Identifier; see isdnNCCI(D4isdn).

info

additional information elements; see isdnInfo(D4isdn). Valid values are:

ISDN_INFOCODE00_OK: logical connection initiated
ISDN_INFOCODE00_BADNCPI: NCPI (Network Control Protocol Information) not supported by current protocol, NCPI ignored. If this value is returned, the set-up of a logical connection is initiated, but the parameter plci has been ignored. In that case, the layer 3 protocol in use does not support NCPI (that is, the transparent mode of layer 3).
ISDN_INFOCODE20_ESTATE: Message not supported in current state
ISDN_INFOCODE20_EPLCI: Illegal controller, PLCI, or NCCI
ISDN_INFOCODE20_NONCCI: Out of NCCI resources
ISDN_INFOCODE30_NCPI: NCPI not supported
