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 LED indicator data (37 bytes) in an

application buffer. Bytes 00-36 contain the indicator status for Feature Keys

01-37, respectively (see

Table 8). As indicated in the example below, Feature

Keys 10, 30, and 38-40 do not have LED indicators.
