FUNCTION
These bits determine the compression capabilities to be
declared in phase B (handshaking) of the T.30 protocol.
These bits determine the compression capabilities to be
used in the transmission and to be declared in phase B
(handshaking) of the T.30 protocol.
Do not change the settings.
Change the setting when communication problems occur
using JBIG compression.
Change the setting when communication problems occur
using JBIG compression.
Do not change the settings.
COMMENTS
If this bit is set to 0, ECM is switched off for all
communications.
In addition, V.8 protocol and JBIG compression are
switched off automatically.
Do not change the setting.
