Mediant 500 E-SBC
♦
[18] Comfort Tone
♦
[23] Hold Tone
♦
[46] Beep Tone
•
Tone Modulation Type: Amplitude Modulated (1) or regular (0)
•
Tone Form: The tone's format can be one of the following:
♦
Continuous (1)
♦
Cadence (2)
♦
Burst (3)
•
Low Freq [Hz]: Frequency (in Hz) of the lower tone component in case of dual
frequency tone, or the frequency of the tone in case of single tone. This is not
relevant to AM tones.
•
High Freq [Hz: Frequency (in Hz) of the higher tone component in case of dual
frequency tone, or zero (0) in case of single tone (not relevant to AM tones).
•
Low Freq Level [-dBm]: Generation level 0 dBm to -31 dBm in dBm (not
relevant to AM tones).
•
High Freq Level: Generation level of 0 to -31 dBm. The value should be set to
32 in the case of a single tone (not relevant to AM tones).
•
First Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
first cadence on-off cycle. For continuous tones, this parameter defines the
detection period. For burst tones, it defines the tone's duration.
•
First Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
first cadence on-off cycle (for cadence tones). For burst tones, this parameter
defines the off time required after the burst tone ends and the tone detection is
reported. For continuous tones, this parameter is ignored.
•
Second Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
second cadence on-off cycle. Can be omitted if there isn't a second cadence.
•
Second Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
second cadence on-off cycle. Can be omitted if there isn't a second cadence.
•
Third Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
third cadence on-off cycle. Can be omitted if there isn't a third cadence.
•
Third Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
third cadence on-off cycle. Can be omitted if there isn't a third cadence.
•
Fourth Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
fourth cadence on-off cycle. Can be omitted if there isn't a fourth cadence.
•
Fourth Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
fourth cadence on-off cycle. Can be omitted if there isn't a fourth cadence.
•
Carrier Freq [Hz]: Frequency of the carrier signal for AM tones.
•
Modulation Freq [Hz]: Frequency of the modulated signal for AM tones (valid
range from 1 to 128 Hz).
•
Signal Level [-dBm]: Level of the tone for AM tones.
•
AM Factor [steps of 0.02]: Amplitude modulation factor (valid range from 1 to
50). Recommended values from 10 to 25.
Notes:
•
When the same frequency is used for a continuous tone and a cadence tone, the
'Signal On Time' parameter of the continuous tone must have a value that is
greater than the 'Signal On Time' parameter of the cadence tone. Otherwise, the
continuous tone is detected instead of the cadence tone.
•
The tones frequency must differ by at least 40 Hz between defined tones.
