● 002:RTN transmission condition (1),
003: RTN transmission condition (2),
004: RTN transmission condition (3)
Use it to set RTN signal transmission conditions. Raise these parameters for more lenient
conditions if errors occur frequently at time of reception because of transmission of the
RTN signal.
NOTE:
Any of the following error codes may be indicated at time of reception because of RTN
signal transmission
##0104, ##0107, ##0114, ##0201
RTN signal transmission condition (1) affects the ratio of error lines to the total number
of lines per single page of received images.
RTN signal transmission condition (2) affects the standard value (*2) of burst errors (*1).
RTN signal condition (3) affects the number of errors not reaching the standard value of
burst errors.
*1: transmission error occurring cover several lines.
*2: for instance, if '15' is set, a single burst error will represent an error occurring
continuously cover 15 lines.
If any of these lines is detected while an image signal is being received, the RTN signal
will be transmitted after receiving the protocol signal of the transmitting
party. Higher parameters restrict the transmission of the RTN signal.
● 005:NCC pause length (pre-ID code)
Use it to set the length of the pause automatically entered between access code and ID
code when the NCC (New Common Carrier) line is used for dialing.
● 006:NCC pause length (post-ID code)
Use it to set the length of the pause automatically entered between ID code and telephone
number of the other party when the NCC (New Common Carrier) line is used for dialing.
● 008: Time from Right After Dialing by Auto-dialing to Start of
Communication
The time to shift to transmission after automatic dialing can be set. The timing to start
communication after connecting to the other party is delayed by the specified period of time.

● 010: line connection identification length
Use it to set the time for identifying the line connection. Raise this parameter if errors occur
frequently at time of communication because of the condition of the line.
NOTE:
Any of the following error codes may be indicated because of the condition of the line
##0005, ##0018
The line condition identification time is between when the dial signal is transmitted and
when the line condition is cut for the transmitting party, while it is between
when the DIS signal is transmitted and when the line is cut for the receiving party.
● 011: T.30 T1 timer (for reception)
Set the T1 timer for the receiver (wait time after DIS transmission starts until a significant
signal is received).
● 012: The maximum number of received lines
The number of lines at reception can be limited.
● 013:T.30 EOL timer
Set it so that the 1-line transmission time is longer for reception to prevent reception errors
caused by a long data length per line (e.g., computer FAX).
● 015: Hooking detection time length
You can set the hooking detection time.
● 016: time length to first response at time of fax/tel switchover
Allows setting of the time from seizing the line till pseudo RBT is sent, when the Fax/ Tel
switching function is operating.
● 017: pseudo RBT signal pattern ON time length,
018: pseudo RBT signal pattern OFF time length (short)
019: pseudo RBT signal pattern OFF time length (long)
Use it to set the pattern of the pseudo RBT signal transmitted at time of a fax/tel switchover.
● 020: pseudo CI signal pattern ON time length,
021: pseudo CI signal pattern OFF time length (short),
022: pseudo CI signal pattern OFF time length (long)
Use it to set the pseudo CI signal pattern transmitted at time of a fax/tel switchover.
