PBX Integration Board User's Guide

4. PBX Systems
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.
