CPT/Cadence Settings

CPT/Cadence setting parameters serve as the basis of an FXO interface to determine whether or not a

PSTN-call receiving party has hung up the phone. If the following parameters differ from the parameters

of the actual assigned lines, it could cause the FXO to continue to engage a line.

Busy Tone Cadence Measurement

•Busy Tone Cadence Measurement and auto learning: Provides a solution of FXO integrated

with PSTN or PBX. FXO will learn the busy tone automatically.

•BTC Detection Sensitivity: The more sensitivity, the more quickly the system will cut off the call. If

the system often cuts off an un-ﬁnished call, select less sensitivity.

The CPT has 3 sets of parameter tables. You can adjust it based on local PSTN or PBX.

Moreover, users can use CPT Auto Detect to detect CPT parameters. Instructions are shown in the

following section. The method to detect CPT is as follows:
