Reading MIC and ICM LED Indicators
The Dialogic
®
PBX Integration Board can determine the state of the MIC and
ICM indicators by using the d42_indicators( ) function to retrieve the LED
indicators data. This function places the LED indicator data (26 bytes) in an
application buffer. Bytes 24 and 25 contain the indicator status for the MIC
and ICM indicators. Refer to the Dialogic
® PBX Integration Software
Reference for more information about using the d42_indicators( ) function.
Example
An application uses the d42_indicators( ) function to retrieve the current data
for the LCD indicators on a given channel on a Dialogic
® PBX Integration
Board. The data placed in the application buffer is shown below. If the data
for byte 24 is 0x07, the indicator for ICM is on. Refer to the Dialogic
® PBX
Integration Software Reference for more information about using the
d42_indicators( ) function.
