LD 56: Flexible Tones and Cadences
Page 731 of 1050
Flexible Tones and Cadences (FTC) is an optional feature which is used to
customize the tones provided to telephone users. FTC is primarily intended
for international markets where tones which are different from the North
American defaults are required.
Overlay program 56 allows the implementation and administration of tone
and ringing parameters for one or more customers. If the FTC feature
(package 125) is not equipped, North American tones and cadences are used.
An FTC table number can be entered for each trunk route at prompt TTBL in
LD 16. Table 0 is the default for all trunk routes and contains the defaults for
North America.
What are tones and cadences?
Tones are used to provide call status to telephone users. A tone is defined by
both the frequency and volume of the sound.
Tones are provided in on and off phases. One or more cycles of on/off cycles
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.
Flexible Tone and Cadence (FTC) Tables
FTC tables define the tones and cadences used for various calling features. Up
to 31 FTC tables can be created. Each table can be associated with one or
more trunk routes by entering the table number in response to prompt TTBL
in LD 16.
