Rev. 1.5 57

Double cadence:

The cadence has a regular On and Off time, A, followed by a On and Off time, B, and

provided that it meets the requirements in terms of frequency and level, it will be

considered as a valid call progress tone after a certain time of validation (see S67 or S23).

An example of this is the cadence for the Italian dial tone.

Double Cadence A and B

Cadence A min and max On time
