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

Error code
A communication error occurred in phase 2 (line probing).
U01800
A communication error occurred in phase 3 (primary channel equivalent device training).
U01810
A communication error occurred in phase 4 (modem parameter exchange).
U01820
Operation was interrupted due to the absence of a common communication speed
U01821
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
Timeout was detected before a correct DNL signal was received.
U02303
A signal other than MPS or EOM signal was received after a DNL signal was received.
U02304

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

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