Dialogic M7324 Manual Do Utilizador

Integration Board connected to the Hicom 150 PBX. The following 
parameters must be set: 

•  D4BD_MSGACCESSON (0x0A) to store the feature access code for 

MWI ON. A string value should be passed as the parameter value. A 
value of **9 is stored by default by the system service at startup time.  

•  D4BD_MSGACCESSOFF (0x0B) to store the feature access code for 

MWI OFF. A string value should be passed as the parameter value. A 
value of ##9 is stored by default by the system service at startup time.  

The following code demonstrates how the d42_setparm( ) function can be 
used in this context:  

    char str parmval[8];  // cannot be more than 8 characters long 
    int paramNumber;   
    paramNumber = D4BD_MSGACCESSOFF;  // or D4BD_MSGACCESSON 
    if ( (rc = d42_setparm(devh, paramNumber, (void *)&str_parmval[0])) == -1) 
    { 
        // error processing 
    } // end d42_setparm 

Note the following:  

•  The string buffer used to pass the parameter cannot be more than seven 

characters plus the NULL terminator.  

•  Once the feature access code is set in this way, the application can do the 

MWI operation using <ESCO> or <ESCF> strings. 

See the Dialogic

 PBX Integration Software Reference for more information 

on the d42_setparm( ) function and the D4BD_MSGACCESSON and 
D4BD_MSGACCESSOFF parameters.  

With the Hicom 300 PBX, the Dialogic

® 

PBX Integration Board can 

determine the state of its Message Waiting Indicator using the 
d42_indicators( ) function to retrieve the LED indicators data. Byte 00 
contains the Message Waiting indicator status (0x00 is off; 0x01 is on). Refer 
to the Dialogic

 PBX Integration Software Reference for more information 

about using the d42_indicators( ) function.
