   #include <sys/scoisdn.h>
   

typedef struct isdnBproto { ...

union isdnB3config { struct /* Used for protocols 1, 2, 3 */ { isdnWord_t lic; isdnWord_t hic; isdnWord_t ltc; isdnWord_t htc; isdnWord_t loc; isdnWord_t hoc; isdnModMode_t moduloMode; isdnWord_t windowSize; } P123;

Description

The isdnB3config structures offer additional configuration information for the B3 protocol specified in isdnB3proto(D4isdn). The complete B-channel protocol information is defined by isdnBproto(D4isdn).

Parameters

For B3 protocol 0 (transparent), this message parameter does not apply (coded as an empty structure).

For B3 protocols 1, 2, and 3 (T.90NL, ISO8208, and X.25 DCE), these structure members are defined:


lic
lowest incoming channel; default is 0

hic
highest incoming channel; default is 0

ltc
lowest two-way channel; default is 1

htc
highest two-way channel; default is 1

loc
lowest outgoing channel; default is 0

hoc
highest outgoing channel; default is 0

moduloMode
mode of operation. Valid values are:

BPROTO_MODE_NORM
normal operation (default)

BPROTO_MODE_EXTENDED
extended operation

windowSize
used to configure non-standard defaults for the transmit window size; default is 2

For B3 protocol 4 (Fax G3), these structure members are defined:


resolution

0
standard

1
high

format

0
SFF (Structured Fax File); default

1
plain fax format (modified Huffman coding)

2
PCX

3
DCX

4
TIFF (Tagged Image File Format)

5
ASCII

6
Extended ANSI

7
binary file transfer

station_id
ID of the calling station, coded in ASCII

headline
headline sent on each fax page, coded in ASCII
