(2-7) E017XX error code table: V.34 transmission
E01700: A communication error that occurs at the transmitting unit in the period after transmission of INFO0 before enter-
ing phase 3 (primary channel equivalent device training). For example, INFO0/A/Abar (B/Bbar, for polling trans-
mission)/INFOh was not detected.
E01720: 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.
E01721: 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.
(2-8) E018XX error code table: V.34 reception
E01800: A communication error that occurs at the receiver unit in the period after transmission of INFO0 before entering
phase 3 (primary channel equivalent device training). For example, INFO0/B/Bbar (A/Abar, for polling reception)/
probing tone was not detected.
E01810: A communication error that occurs at the receiver unit in phase 3 (primary channel equivalent device training).
For example, S/Sbar/PP/TRN was not detected.
E01820: A communication error that occurs at the receiver unit in the period after initiating the control channel before
entering the T.30 process. For example, PPh/ALT/MPh/E was not detected.
E01821: 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, a DCN signal was transmitted to the des-
tination unit and the line was cut.
(2-9) U023XX error code table: Relay command abnormal reception
(2-10) U044XX error code table: Encrypted transmission
Error code Description
E01700 A communication error occurred in phase 2 (line probing).
E01720 A communication error occurred in phase 4 (modem parameter exchange).
E01721 Operation was interrupted due to the absence of a common communication speed between units.
Error code Description
E01800 A communication error occurred in phase 2 (line probing).
E01810 A communication error occurred in phase 3 (primary channel equivalent device training).
E01820 A communication error occurred in phase 4 (modem parameter exchange).
E01821 Operation was interrupted due to the absence of a common communication speed between units.
Error code Description
U02303 Timeout was detected before a correct DNL signal was received.
U02304 A signal other than MPS or EOM signal was received after a DNL signal was received.
Error code Description
U04400 Encrypted transmission was interrupted because encryption keys did not agree.
U04401 Calling failed during encrypted transmission because the encryption key was not registered.
