No.008 V.34 Modulation Speed Upper Limit; No.009 V.34 Data Speed Upper Limit; No.010 Frequency Of The Pseudo Ci Signal; Setting Of Numeric Parameter (Numeric Param.) - Canon iR2020 Series Service Manual

14.4.5 <No.008 V.34 modulation speed upper limit>
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
Use it to set an upper limit to the modulation speed (baud rate) for the V.34 primary channel.
14.4.6 <No.009 V.34 data speed upper limit>
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
Use it to set an upper limit to the data transmission speed for the V.34 primary channel between 2.4K and 33.6K bps in increments of 2400 bps. (0: 2.4K to 13:
33.6K bps).
14.4.7 <No.010 Frequency of the pseudo CI signal>
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
You may select a frequency for the pseudo CI signal.
Some types of external telephones do not ring when the fax/tel switch-over function is ON. To sound the ring, change the pseudo CI signal.

14.5 Setting of Numeric Parameter (NUMERIC Param.)

14.5.1 Numerical Parameter Composition

iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
14.5.2 <002: RTN transmission condition (1)><003: RTN transmission condition (2)><004: RTN transmission condition (3)>
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
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.
