Signal attenuation for G3 fax
signals received from ISDN line (-
6dB)
0: Off 1: On
0: If an analog signal comes over digital line,
the signal level after decoding by the TE is
theoretically the same as the level at the
entrance to the digital line. However, this
sometimes causes the received signal level
to be too high at the received end. In this
case, set this bit to 1 to adjust the
attenuation level.
