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
