For example, a RTTTL ringing tone:
name of the ringing tone: d=4, o=5, b=108: 2a4, 2e, 2d#, 2b4, 2a4, 2c, 2d, 2a#4,
2e., e, 1f4, 1a4, 1d#, 2e., d, 2c., b4, 1a4, 1p, 2a4, 2e, 2d#, 2b4, 2a4, 2c, 2d, 2a#4,
2e., e, 1f4, 1a4, 1d#, 2e., d, 2c., b4, 1a4
The three parts are separated with a colon.
•
Part 1: name of the ringing tone, some characters presenting the name of the
ringing tone.
•
Part 2: default values (here: d=4, o=5, b=10), where "d=" is the default
length of a note. In this case "4" means that each note without a length
description is a quarter of a note. "8" means an eighth of a note and so on.
Further on "o=" is the default octave. There are four octaves in the RTTTL-
format. "b=" describes the playing speed in hits per minute.

Part 3: The notes. All notes are separated with commas have the following
content: First the optional length description, a normal music note, (c, d, e, f,
g, a, b (= international tone description)). Hashes have the function of a
cross. B signs aren’t existing in the RTTTL format. Then follows the octave
description. Missing optional descriptions are replaced with the default
parameter.
