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 trans-
mission of the RTN signal.
Memo:
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.
14.5.3
0016-2051
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.
14.5.4
0016-2052
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.
14.5.5
0016-2053
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.
Memo:
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.
14.5.6
0016-2054
Set the T1 timer for the receiver (wait time after DIS transmission starts until a significant signal is received).
14.5.7
0016-2055
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).
14.5.8
0016-2057
Allows setting of the time from seizing the line till pseudo RBT is sent, when the Fax/ Tel switching function is operating.
14.5.9
pseudo RBT signal pattern OFF time length (long)>
0016-2058
Use it to set the pattern of the pseudo RBT signal transmitted at time of a fax/tel switchover.
14.5.10
pseudo CI signal pattern OFF time length (long)>
0016-2059
Use it to set the pseudo CI signal pattern transmitted at time of a fax/tel switchover.
14.5.11
0016-2060
Use it to set the CNG detention level for a fax/tel switchover.
14.5.12
0016-2061
Use it to set the pseudo transmission level for a fax/tel switchover.
14.5.13
0016-2062
Sets the signal detection time for the answering machine connection function operation. When the answering machine connection function is operating, if the func-
tion does not operate normally because the fax does not detect CNG signal sent from the line, raise this parameter to increase the signal detection time.
14.5.14
0016-2063
Use it to detect the time of detection after which command analysis is started after detecting V.21 low-speed command preambles continuously for a specific period
of time.
14.5.15
0016-2064
Use it to confirm the count type indicated on the Counter Check screen, which appears in response to a press on the Counter key.
When '0' is selected, count type will not be indicated.
No.56: Use it to indicate the type of software counter 1 of the control panel. The type of soft counter 1 cannot be changed.
No.57: Use it to change the type of soft counter 2* of the control panel to suit the needs of the user.
No.58: Use it to change the type of soft counter 3* of the control panel to suit the needs of the user.
