When there is an incoming/outgoing call on/from the CO port is answered, the system will check whether
the flag Disconnect Tone detection is enabled. Only if the flag is enabled, the system will detect the
Disconnect Tone.
If Disconnect Tone is detected, the system will consider the call as ended and will release the CO port.
• Call Disconnect Tone Frequency: To enable the system to detect the Call Disconnect Tone accurately,
you must set the Frequency of the Disconnect Tone, as supported by the CO network.
• Frequency 1 (Hz): Frequency 1 is from 0000 to 4095 Hz. Default: 0400Hz
• Operator: This parameter has 3 options: No operator, Modulation (*), Addition (+). Default: None.
If None is selected, frequency 2 will not be applicable.
If Modulation is selected, frequency 1and frequency 2 will be used as modulation, F1* F2
If Addition is selected, frequency 1 and frequency 2 will be used as addition, F1 + F2.
• Frequency 2 (Hz): Frequency 2 is from 0000 to 4095 Hz. Select Frequency 2 if Dual Frequency Call
Disconnect Tone is supported by the CO network. Default: 0000Hz.
• Call Disconnect Tone Cadence: To enable the system to detect the Call Disconnect Tone accurately,
you must also set the Cadence (ON-OFF time) of the Disconnect Tone, as supported by the CO network.
• ON Time 1 (ms), OFF Time 1 (ms): Select Cadence for the first cycle ON Time1 and OFF Time 1. It
may be 0000 to 4095 milliseconds. Default: 0750 ms ON Time 1, 0750 ms OFF Time 1
• ON Time 2 (ms), OFF Time 2 (ms): Select Cadence for the second cycle ON Time 2 and OFF Time 2.
It may be 0000 to 4095 milliseconds. Default: 0750 ms ON Time 2, 0750 ms OFF Time 2.
• ON Time 3 (ms), OFF Time 3 (ms): Select Cadence for the third cycle ON Time 3 and OFF Time 3. It
may be 0000 to 4095 milliseconds. Default: 0000 ms ON Time 3, 0000 ms OFF Time 3.
• ON Time 4 (ms), OFF Time 4 (ms): Select Cadence for the fourth cycle ON Time 4 and OFF Time 4. It
may be 0000 to 4095 milliseconds. Default: 0000 ms ON Time 4, 0000 ms OFF Time 4.
When call disconnect tone detected on the port matches the Frequency and Cadences you have set, the
call will be disconnected and the CO port will be released.
When Disconnect cadence is zero, VISIONPRO will skip that cadence and match the next cadence.
• Ring Cadence OFF Timer: Configure this timer to set the OFF time for Ring cadence. During the
incoming call on CO port, if the CO gives ring in which the Ring OFF period is quite long, the system will
consider that the ring has been stopped, and will stop ringing the SLT port, even though the incoming call
is still present.
To get accurate indication, the system supports Ring Cadence OFF timer on CO port so that ring can
continue even for incoming calls with long Ring OFF period.
The range of the Ring Cadence OFF timer is from 1 to 9 seconds. By default the timer is set to 6 seconds.
