Mitel Superset 420 or 430 Phone with SX-200 or SX-2000 PBX
As shown in Figure 9, there are six Display Keys or Soft Keys located below
the LCD display on the Mitel Superset 430 telephone. These keys are
associated with specific prompts shown on the LCD display depending on the
current state of the phone.
NOTE: In order to read the soft key prompts from the Mitel Superset 430
phone, 160 bytes of display data must be read that was not supported
until Dialogic® System Release Software 5.1.1 Feature Pack 1. Use
the d42_displayex( ) function to get 160 bytes of data for Mitel
Superset 430 integration only.
Reading Display Key Prompts:
The Dialogic® PBX Integration Board can determine which of its prompts are
currently displayed by using the d42_displayex( ) function to retrieve display
data and read the information for the bottom two rows (last 80 characters).
NOTE: The display key prompts and locations may be different in SX-200
and SX-2000 PBXs with the same Superset 430 phone emulation.
Refer to the Dialogic® PBX Integration Software Reference for more
information about using the d42_displayex( ) function.
Pressing Display Keys:
The Dialogic® PBX Integration Board can respond to a prompt and “press” the
appropriate Display Key using the dx_dial( ) function. Refer to the Dialogic®
PBX Integration Software Reference for more information about dialing
programmable keys. As shown in Table 20 and Table 21, each Display Key on
Superset 420/430 telephones is assigned a dial string sequence. By using the
dx_dial( ) function and the appropriate dial string, the PBX Integration Board
can press any of its Display (Soft) Keys.
