4.6.3. Programmable Feature Keys
As illustrated in
Figure 15, there are 16 Programmable Feature Keys located
below the display on the M2616 telephone. These keys can be configured
either during PBX installation or by the user (using the telephone set or the
Dialogic
®
PBX Integration Board). The Line, Program, and Handsfree keys
are assigned during PBX configuration and cannot be user programmed. There
is an LCD indicator associated with each Feature Key. The LCD indicators are
triangular and can take on one of the six states listed in
Table 31.

The Dialogic
®
PBX Integration Board can determine the state of its LCD
indicators by using the d42_indicators( ) function to retrieve the LCD
indicators data. This function places the Line Indicator data (16 bytes) in an
application buffer. Bytes 00-15 contain the indicator status for Feature Keys
00-15, respectively (see
Table 32).
