4.4.4. Function Keys
As shown in Figure 8 and Figure 9, there are a number of Function Keys
found to the left of the dial key pad on the Mitel Superset 420/430 telephones.
The Dialogic® PBX Integration Board can emulate these keys to perform
various operational functions.
Pressing Function Keys
The Dialogic® PBX Integration Board can “press” any of its function keys
using the dx_dial( ) function. Each function key on Superset 420/430
telephones is assigned a dial string sequence (refer to Table 18 and Table 19 ).
By using the dx_dial( ) function and the appropriate dial string, the PBX
Integration Board can dial any of its function keys. Refer to the Dialogic®
PBX Integration Software Reference for more information about dialing
programmable keys.
