value of eight [0x08] indicates ON), while the green light has six possible
values. The status of the indicators is obtained by bitwise-ANDing the
returned value from the green light with the value from the red light (green
light value + red light value). In other words, the value for a line indicator in
use with a call (after ANDing with 0x0f, all the values shown below in the
least significant byte value) would be nine--0x08 (for red light on) + 0x01 (for
green light on). The status conditions for each byte (least significant) of the
green light are defined as indicated in

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 (34 bytes) in an
application buffer. Bytes 1-34 contain the indicator status for Memory Keys
00-33, respectively (see
