71 1,2 Frequency range setup
for detection of DT/BT
Used to set the frequency range for detection of dial tone and busy tone.
When dial tone or busy tone is erroneously detected, change the setting.
( ): Theoretically proper area
1 245Hz ~
650Hz

3 Busy tone detection Used to set whether the busy tone signal is detected or not during automatic
dialing or ringing of pseudo-call of an external telephone.
0 Detected
4,5 Busy tone detection
cycle
Used to set the number of pulses for judgment of busy tone signal detection. 0 2 pulses
0
6,7 DT/BT detection level Used to set the minimum detection level for judgment of dial tone and busy tone
detection. If a signal level is lower than this setup, it is ignored.
0 -43dB
0
8 None-detection time of
busy tone OFF
Used to set none-detection time of busy tone OFF.
Change the setup when busy tone ON section is abnormal due to noises.
0 100ms
72 1,2 Lower limit of busy tone
detection time
(ON time)
Used to set the lower limit of detection time (ON time) of busy tone signal
frequency. To count a busy tone signal as 1 pulse, it must be detected for more
than the set time.
For CTR21, 150ms.
0 250ms

3,4 Upper limit of busy tone
detection time
(ON time)
Used to set the upper limit of detection time (ON time) of busy tone signal
frequency. To count a busy tone signal as 1 pulse, it must be detected for less
than the set time.
0 750ms
0
5,6 Lower limit of busy tone
OFF detection time
Used to set the upper limit of ON time when detecting the busy tone signal
frequency. If the busy tone signal is detected over this setup, it is not counted as
one pulse.
