isdnInfoNbr(D4isdn)
isdnInfoNbr --
ISDN information number
Synopsis
#include <sys/types.h>
#include <sys/scoisdn.h>
typedef isdnWord_t isdnInfoNbr_t;
Description
The isdnInfoNbr parameter specifies the coding of the
isdnInfoEl(D4isdn)
parameter, as well as the type of information that is carried by
the
ISDN_INFO.ISDN_IND(D7isdn)
message. The high byte is structured as a bit field and
indicates which type of information is held in the low byte.
The following bit values are valid:
ISDN_INFONBRMSK_ELEMPTY-
0x8000: [15] info element empty. If this bit is set, the low byte
containing the message type is coded according to Q.931.
In this case, the ISDN_INFO.ISDN_IND message
indicates the occurrence of a network event according to the
specified message, and the parameter isdnInfoEl is an
empty ISDN driver structure.
ISDN_INFONBRMSK_SUPINFO-
0x4000: [14] supplementary info. If this bit is set, the low byte
represents supplementary information. The defined values are:
0-
sum of charges in charging units.
1-
sum of charges in national currency
In both cases, the isdnInfoEl parameter contains the
content of the information element.
If both bits are cleared, the low byte represents an information
element type coding according to Q.931, and the
isdnInfoEl parameter contains the content of the
information element.
