Reading LED Indicators
The Dialogic® PBX Integration Board can determine the state of its LED
indicators by using the d42_indicators( ) function to retrieve the LED
indicators data. This function places the Line Indicator data (12 bytes) in an
application buffer. Bytes 0-11 contain the indicator status for Feature Keys 00-
11, respectively (see Table 11 and Table 12).
