the local terminal. This function is only

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.
(0,1): The machine will disconnect the line without
sending a fax message, if the last 8 digits of the
received CSI do not match the last 8 digits of the
dialed telephone number. This does not work when
manually dialed.
(1,0): The same as above, except that only the last 4
digits are compared.
(1,1): The machine will disconnect the line without
sending a fax message, if the other end does not
identify itself with an RTI or CSI.
(0,0): Nothing is checked; transmission will always go
ahead.
• This function does not work when dialing is done
from the external telephone.
Do not change the setting.
