COMMENTS
These bits determine the compression
capabilities declared in phase B
(handshaking) of T.30 protocol.
These bits determine the compression
capabilities used in the transmission and
declared in phase B (handshaking) of T.30
protocol.
0: If JBIG compression is already in use,
MMR compression is used.
1: If JBIG compression is already in use, any
jobs following are placed on hold until the
JBIG resource becomes free.
If this bit is 0, JBIG optional mode is switched
off for reception. Change the setting when
communication problems occur using JBIG
compression.
This bit determines the priority for the
compression mode used for JBIG
transmission.
Change the setting when communication
problems occur using JBIG compression.
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.
