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.
