Error TX /
code RX
##670 TX In V.8 late start, the DIS V.8 ability from the
receiving machine was detected, and CI was sent in
response; however, the procedure failed, causing
T1 time-over.
##671 RX In V.8 call reception, the procedure fails to proceed
to phase 2 after CM detection, causing T1
time-over.
##672 TX In V.34 transmission, the procedure fails to proceed
from phase 2 to phase 3 or later, causing T1
time-over
##673 RX In V.34 reception, the procedure fails to proceed
from phase 2 to phase 3 or later, causing T1
time-over
##674 TX In V.34 transmission, the procedure fails to proceed
from phase 3 or 4 to the control channel or later,
causing T1 time-over
##675 RX In V.34 reception, the procedure fails to proceed
from phase 3 or 4 to the control channel or further,
causing T1 time-over
##750 TX After transmitting PPS-NULL in ECM transmission,
no significant signal has been received, and
re-transmission of the procedure signal has been
attempted the number of specified times but failed.
##752 TX After transmitting PPS-NULL in ECM transmission,
DCN has been received.
##753 TX After transmitting PPS-NULL in ECM transmission,
re-transmission of the procedure signal has been
attempted the number of specified times but failed,
