(2-7) U017XX error code table: V.34 transmission

Error code
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.
U01700: 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 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 sig-
nal, the unit transmitted a DCN signal, and the line was cut.

(2-8) U018XX error code table: V.34 reception

Error code
U01800 A communication error occurred in phase 2 (line probing).
U01810 A communication error occurred in phase 3 (primary channel equivalent device training).
U01820 A communication error occurred in phase 4 (modem parameter exchange).
U01821 Operation was interrupted due to the absence of a common communication speed between units.
U01800: 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.
U01810: 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.
U01820: 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.
U01821: 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 destination
unit and the line was cut.

(2-9) U023XX error code table: Relay command abnormal reception

Error code
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.

(2-10) U044XX error code table: Encrypted transmission

Error code
U04400 Encrypted transmission was interrupted because encryption keys did not agree.
U04401 Calling failed during encrypted transmission because the encryption key was not registered.
