15.5.2 <002: RTN transmission condition (1)><003: RTN transmission condition (2)><004: RTN transmission condition (3)>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

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.

15.5.3 <005: NCC pause length (pre-ID code)>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

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.

15.5.4 <006: NCC pause length (post-ID code)>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

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.

15.5.5 <010: line connection identification length>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

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.

15.5.6 <011: T.30 T1 timer (for reception)>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

Set the T1 timer for the receiver (wait time after DIS transmission starts until a significant signal is received).

15.5.7 <013: T.30 EOL timer>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

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).

15.5.8 <015: hooking detection time>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

Allows setting of the hooking detection time.

15.5.9 <016: time length to first response at time of fax/tel switchover>

/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /

Allows setting of the time from seizing the line till pseudo RBT is sent, when the Fax/ Tel switching function is operating.

15.5.10 <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)>
