Ringing tone (example)
Explanation of Parameters 942, 943, 944
Busy tone
Example:
The busy tone in the figure above is considerably longer than the pause time.
Therefore, set parameter
according to the pause, to 200 ms, e.g., and parameter
942
according to the tone, to 600 ms, for example. In this case, however, the default
943
values can be maintained for both the parameters. Since the tone – pause difference is
500 − 250 = 250 ms,
to 300 ms, for example.
set parameter 944
Note
Increase parameter 944 also when the intercom is placed in a hall or
corridor with a large decay time.
