System parameters OCM call classification

Last Updated : Nov 09, 2012 |

Administers the country tone characteristics for Outbound Call Management (OCM) applications. It is not required for United States OCM applications. This screen defines the busy tone and cadence and can be administered with up to four on and off steps, which is four valid cycles to determine busy tone.

Use a minimum of two on and off steps to determine a valid busy tone. If the cadence is administered with one on and off step, any time the classifier hears the cadence it is BTD signal.

Available only if Global Call Classification is enabled for the system, or when Enable Busy Tone Disconnect for Analog loop-start Trunks is enabled for the system.

Example command: change system-parameters ocm-call-classification

Cadence Classification After Answer


Valid Entry	Usage
y	Communication Manager puts call classifiers into modes that listen for call progress tones while listening the voice, with or without Answering Machine Detection (AMD).
n	No-cadence call classification modes detect live voice with or without AMD whenever Communication Manager receives a connect or answer supervision message from an outbound trunk. These modes do not detect any call progress tone cadence.

Global Classifier Adjustment (dB)

Valid Entry	Usage
0 to 15	Specifies the dB loss adjustment. where 0 is the least adjustment, and 15 is the most adjustment.

USA Default Algorithm

Enables or disables the use of the default United States tone detection.

USA SIT Algorithm

Valid Entry	Usage
y	Uses the United States (SIT) tone characteristics for SIT tone detection.
n	The system treats tones with the administered tone name intercept as if they were SIT VACANT, and treats tones with the administered tone name information as if they were SIT UNKNOWN.

Cadence Step

Identifies the number of each tone cadence step and indicates whether the tone is on or off during this cadence step.

Duration Maximum

Valid Entry	Usage
75 to 6375	The upper limit in milliseconds of the tone duration in increments of 25.

Duration Minimum

Valid Entry	Usage
75 to 6375	The lower limit in milliseconds (msec) of the tone duration in increments of 25.

Instance

Valid Entry	Usage
1 to 8	The number distinguishes tones that have the same name but more than one definition of silence and tone-on characteristics.

Tone Continuous

Valid Entry	Usage
y	Indicates a continuous tone.
n	Indicates a non-continuous tone.

Tone Name

Valid Entry	Usage
busy information intercept reorder ringback	The name of the tone. Busy is required when Busy Tone Disconnect for Analog Loop-start Trunks is enabled or Global Call Classification is disabled for the system. Required for tone definition outside of the U.S. and Canada.
