Field –2 to Field –5 Composition:
Field - 2/3/4/5 share the same definition, and each field describes one single cadence segment. Together, the four (4) fields
form a macro-segment, which will be repeated until ringing expires.
The expression is a string of numeric values with the special notation ' ( ' , ' ) ' and ' , '
It has the format as per the following construct: t(on_0+off_0,on_1+off_1,on_2+off_2,on_3+off_3)
t : The cadence segment duration in seconds.

Negative value: Ringing indefinitely

No value: Ringing indefinitely

Zero value: Ringing is skipped

Positive value: Normal ringing duration
on_0/1/2/3 : The ring active time in seconds.

Negative value: Not allowed

No value: Infinite ring active time

Others: Normal ring active time (up to 3 decimated digits)
off_0/1/2/3 : The ring inactive time in seconds

Negative value: Not allowed

No value: Infinite ring inactive time

Others: Normal ring inactive time (up to 3 decimated digits)
Example: 4(.3+2.34,2+1.5)
The above example illustrates a ringing tone comprised of two segments. Ringing is active for 0.3 seconds, followed by 2.34
seconds of silence, then ringing for 2 seconds, and followed by 1.5 seconds of silence.
The above cadence operates repeatedly for 4 seconds.
