reception
(CED tone send interval)
7 Countermeasures
against echo in
transmission
(Used to set the hold
time from DIS reception
to signal sending.)

(T0 timer setup)
4-7 T1 timer setup
8 Not used
22 1-4 Not used
5,6 T4 timer setup at auto

(+1.5sec for manual)
7,8 Not used
23 1 EOL detection timer
2-6 Not used
7,8 RTN send line error rate Used to set the threshold value for judgment of RTN sending in G3 reception.
24 1 DCS-TCF interval time
Switch selection and function
Used to set the time interval (sec) from sending CED or ANSam to sending
FSK signal of DIS.
1: 500msec
If either SW20-6 or SW2-7 is YES, disconnection of the line after completion of
communication is delayed for 1.5sec.
Used to set the time interval (sec) from DIS reception to DCS signal sending.
This is valid only in the mode other than V.34.
1: 500msec
Used to set the time (sec) of calling when the other party does not receive the
call in automatic transmission.
The set range is 30 - 75sec in the increment of 15sec by binary input of N into
"(15sec x N) + 30sec." The set range of N is 0 ~ 7. When set to a value outside
the set range, the initial value of the destination is applied to.
Used to set the time (sec) for connection of line when the other party does not
respond in FAX communication.
The set range is 30 - 105sec in the increment of 5sec by binary input of N into
"(5sec x N) + 30sec." N is set in the range of 0 - 15. T1 timer is the timer for the
time from recognition of FAX CED or DCS) by the other party after connection
of line. The ITU-T standard is 35 ± 5sec.
Used to set the timer up to respond and receive.
Timer for DCS signal to respond and receive.
For the ITU-T standard, 3sec ± 15%.
Bit No.
3sec
4sec
5sec
6sec
Used to set the detection timer (sec) of EOL (End Of Line) in Phase C reception
of G3 mode.
1: 25sec
If an error occurs in EOL detection, it is processed as EOL not detected.
The threshold value is of STD conversion. The half of this value is used for
judgment of RTP sending.
Bit No.

When, for example, FINE is received, the threshold value is doubled.
Used to set the time interval (sec) from DCS sending to TCF signal sending.
1: 150msec
The ITU-T standard is 75 ± 20ms.
