Configuring the Remote Gateway 9150 unit
Field
No of Cycles
Cadence Time
190
Description
Enter the number of cycles that you want in the tone type
you selected.
Two fields in the Cadence Time field become active for
each cycle you request. That is, they are no longer
dimmed. The boxes turn white, signifying that you can
enter information into that box. For example, if you choose
1 cycle, two boxes turn white. If you choose 3 cycles, six
boxes turn white, and so on.
Valid options are 1, 2, 3, and 4.
Tones include on and off phases. One or more cycles of on
and off phases make up a tone's cadence. For example, the
default cadence for normal North American ringing is 2
seconds on, 4 seconds off, 2 seconds on, 4 seconds off, and
so on. In the Cadence Time fields, enter the length, in
milliseconds, of the phases of the cadence that you want to
configure for the tone type you selected.
Find the proper entries for the Cadence Time fields in the
FTC: Flexible Tones and Cadences data block in the
Prompts and Responses section of the X11 Administration
Guide (NTP 553-3001-311).
You can also calculate these entries using the formula in
the following example, which calculates a phase of 2
seconds (2000 milliseconds [ms]):
For 96 ms cadence increments:
2000/96 = 20.83 = 21 (always round up)
21 * 96 = 2016
multiple of 5 closest to 2016 = 2015
2015 / 5 = 403
