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.
