4.7.4. Function Keys
There are eight Function keys located next to the dial pad keys in two groups:
• FNC, CNF, LNR/SPD, SPKR, and ANS. There is a two-color LED
indicator associated with each of these function keys. The LED indicators
can take one of the states listed in
Table 34.
• RECALL, TRF, and HOLD. These keys do not have any LED
associated with them.
Reading LCD Indicators on Function Keys
The Dialogic
®
PBX Integration Board can determine the state of its LED
indicators on the Function keys by using the d42_indicators( ) function to
read the LCD indicators data. This function places the LED indicator data (26
bytes) in an application buffer. Bytes 18-23 (excluding byte 20, which is not
used) contain the LED indicator status for Feature keys (see
Table 37). Refer
to the Dialogic
®
PBX Integration Software Reference for more information
about using the d42_indicators( ) function.
