Pattern ID |
Description |
---|---|
Pattern-specific configuration (see CPA Pattern Configure message) 0x01 = Last Interval Continuous (for pattern ending with continuous tone) 0x02 = Detect Tone After Determination (for reporting Intercept Tones) 0x04 = Use As Internal Dial Tone (to detect dial tone without invoking Call Progress Analysis) |
|
Call Progress Analysis Result to report when a pattern has been matched but discontinues before "interval cycles to report". (CPA Result message). |
|
The number of times an Interval Sequence must be repeated before declaring the pattern valid |
|
The number of times an Interval Sequence must be repeated before reporting a Call Progress Result to the host |
|
The number of Interval Descriptors in the pattern |
|
An Interval Descriptor is a list of the tones and intervals that constitute a pattern. The Excel platform uses the Interval Descriptor to confirm that a specific pattern has been detected. An Interval Descriptor consists of the Tone ID, Min. Filter, and Max. Filter, where: Tone ID – A valid Tone ID Minimum/Maximum Filter (MSB, LSB) – Minimum and maximum duration for this tone interval - A tone is determined as valid if the on and off cycles fall within the minimum and maximum times. |
