376 V6100 and V7122 User GuideFormat of the Call Progress Tones Section in the ini FileUsers can create up to 32 different Call Progress Tones, each with frequency and formatattributes.The frequency attribute can be single or dual-frequency (in the range of 300 Hz to 1980 Hz),or an Amplitude Modulated (AM). In total, up to 64 different frequencies are supported. Onlyeight AM tones, in the range of 1 to 128 kHz, can be configured (the detection range islimited to 1 to 50 kHz). Note that when a tone is composed of a single frequency, the secondfrequency field must be set to zero.The format attribute can be one of the following: Continues - (e.g., dial tone) a steady non-interrupted sound. Only the ‘First Signal Ontime’ should be specified. All other on and off periods must be set to zero. In this case,the parameter specifies the detection period. For example, if it equals 300, the tone isdetected after 3 seconds (300 x 10 msec). The minimum detection time is 100 msec. Cadence – A repeating sequence of on and off sounds. Up to four different sets of on /off periods can be specified. Burst – A single sound followed by silence. Only the ‘First Signal On time’ and ‘FirstSignal Off time’ should be specified. All other on and off periods must be set to zero. Theburst tone is detected after the off time is completed.Users can specify several tones of the same type. These additional tones are used only fortone detection. Generation of a specific tone conforms to the first definition of the specifictone. For example, users can define an additional dial tone by appending the second dialtone’s definition lines to the first tone definition in the ini file. The V7122 reports dial tonedetection if either of the two tones is detected.The Call Progress Tones section of the ini file comprises the following segments: [NUMBER OF CALL PROGRESS TONES] – Contains the following key: ‘Number of Call Progress Tones’ defining the number of Call Progress Tones that aredefined in the file. [CALL PROGRESS TONE #X] – containing the Xth tone definition (starting from 1 andnot exceeding the number of Call Progress Tones defined in the first section) using thefollowing keys: Tone Type – Call Progress Tone typeFigure 127 Call Progress Tone Types1.
