Calibrating DTMF Tone Sequences
The Kaleido-IP can detect 16 specific DTMF sequences in a SCTE 35 stream, to trigger up
to 8 DTMF break alarms and to return their status to normal. Define the sequences,
matching those used in the actual programs you wish to monitor.
To calibrate out-of-network, and in-network DTMF tone sequences
1 In the main window, click the System tab, and then click the Calibrations (Kaleido-IP)
tab on the second-level tab bar.
2 In the Tools pane, select the SCTE 35 profile you wish to configure, and then click DTMF
