MP-1xx/H.323 User’s Manual 74 Document #: LTRT-00651
Using this configuration file, the User can create up to 16 different call progress tones using up to
15 different frequencies (in the range of 300 Hz to 2000 Hz). Each one of the call progress tones
is specified by the following two parameters: the tone frequency (either single or dual frequencies
are supported) and the tone cadence. This is specified by 2 sets of ON/OFF periods, but Users
can discard the use of the first On/Off cycle by setting the relevant parameters to zero. When the
tone is made up of a single frequency, the second frequency field should be set to zero.
For a continuous tone (such as dial tone), only the “First Signal On time” should be specified. In
this case, the parameter specifies the detection period. For example if it equals 300, then the tone
is detected after 3 seconds (300 x 10 msec).
Note 1: When defining several continuous tones, the “First Signal On Time” parameter should have the
same value for all tones.
Note 2: The tones frequency should differ by at least 40 Hz from one tone to other defined tones.
6.4.2 Default Template for Call Progress Tones
The MP-1xx is initialized with the default Call Progress Tones configuration template shown in
Table 6-4. If you need to change one of the tones, edit the default call progress.txt file.
For example: to change the dial tone to 440 Hz only, replace the #Dial tone section in Table 6-4
with the following text:
#Dial tone
[CALL PROGRESS TONE #1]
Tone Type=1
Low Freq [Hz]=440
High Freq [Hz]=0
Low Freq Level [-dBm]=10 (-10 dBm)
High Freq Level [-dBm]=32 (use 32 only if a single tone is required)
First Signal On Time [10msec]=300; the dial tone is detected after 3 sec
First Signal Off Time [10msec]=0
Second Signal On Time [10msec]=0
Second Signal Off Time [10msec]=0
Users can specify several tones of the same type using Tone Type definition. These additional
tones are used only for tone detection. Generation of specific tone is according to the first
definition of the specific tone. For example, the User can define an additional dial tone by
appending the second dial tone definition lines to the tone ini file. The MP-1xx reports dial tone
detection if either one of the two tones has been detected.
