(2-7) U017XX error code table: V.34 transmission
U01700: A communication error that occurs at the transmitting unit in the period after transmission of INFO0
before entering phase 3 (primary channel equivalent device training). For example, INFO0/A/Abar (B/Bbar, for
polling transmission)/INFOh was not detected.
U01720: A communication error that occurs at the transmitting unit in the period after initiating the control
channel before entering the T.30 process. For example, PPh/ALT/MPh/E was not detected.
U01721: In the absence of a common communication speed between units (including when an impossible
combination of communication speed and symbol speed occurs) after MPh exchange; 1) a DCN signal was
received from the destination unit, and the line was cut; or 2) a DIS (NSF, CSI) signal was received from the
destination unit and, in response to the signal, the unit transmitted a DCN signal, and the line was cut.
U01152
A DCN signal was received after transmission of a CTR signal (ECM).
U01153
A DCN signal was received after transmission of an ERR signal (ECM).
U01154
A DCN signal was received after transmission of an RNR signal (ECM).
U01155
A DCN signal was received after transmission of an SPA signal (short protocol).
U01160
During message reception, transmission time exceeded the maximum transmission time
per line.
U01161
Number of error lines exceeded limits during message reception.
U01162
A break in loop current was detected during message reception.
U01163
Polarity reversal was detected during message reception.
U01164
One page length exceeded the specified length during message reception.
U01170
A decoding error occurred during MMR message reception.
U01172
During reverse polling in V.34 mode at the transmitting unit, a JM signal was not
detected after transmission of a CM signal when receiving after transmission.
U01191
Communication was interrupted because an error occurred during an image data recep-
tion sequence in the V.34 mode.
U01199
A DIS signal with different FIF was received after transmission of a DIS signal.
Error code Description
U01700
A communication error occurred in phase 2 (line probing).
U01720
A communication error occurred in phase 4 (modem parameter exchange).
U01721
Operation was interrupted due to the absence of a common communication speed
between units.
