No FUNCTION COMMENTS
0-1 Compression modes available in
receive mode
Bit 1 0 Modes
0 0 MH only
0 1 MH/MR
1 0 MH/MR/MMR
1 1 MH/MR/MMR/JBIG
These bits determine the compression
capabilities declared in phase B (handshaking)
of T.30 protocol.
2-3 Compression modes available in
transmit mode
Bit 3 2 Modes
0 0 MH only
0 1 MH/MR
1 0 MH/MR/MMR
1 1 MH/MR/MMR/JBIG
These bits determine the compression
capabilities used in the transmission and
declared in phase B (handshaking) of T.30
protocol.
4 Not used Do not change the setting.
5 JBIG reception mode
0: Standard mode only
1: Standard and optional mode
(default)
If this bit is 0, JBIG optional mode is switched
off for reception. Change the setting when
communication problems occur using JBIG
compression.
6 Priority for JBIG mode used for
transmission
0: Standard mode
1: Optional mode (default)
This bit determines the priority for the
compression mode used for JBIG transmission.
Change the setting when communication
problems occur using JBIG compression.
7 Closed network (reception)
0: Disabled 1: Enabled
1: Reception will not go ahead if the ID code of
the other terminal does not match the ID code
of this terminal. This function is only available in
NSF/NSS mode.
