The programmable RS-232 message waiting indicators interface is configured entirely offline, through the RS-232 Only Application Menu. This procedure assumes that the appropriate server hardware and software have been installed.
Note: Perform the following steps to configure the programmable RS-232 message waiting indicators interface in a server:
Complete an RS-232 Message Waiting Indicators Interface Worksheet.
To enable the RS-232 Message Waiting Indicators Interface application and allow for RS-232 cabling, define an RS-232 serial port. See Defining an RS-232 Serial Port.
Create the interface string. See Creating a Programmable RS-232 Interface String.
Set delay times to allow for PBX processing of RS-232 message waiting indicators requests. See Setting Delay Times for RS-232 Message Waiting Requests.
Enable or disable indicator-on requests for successive messages. See Enabling/Disabling Light-on Requests for Successive Messages.
If desired, have the number of unplayed messages sent after the directory number when the server issues a request to turn indicators on. See Sending the Number of Unplayed Messages through the Programmable RS-232 Interface.
Compensate for different directory number and mailbox numbers, if necessary. See Compensate for Different Directory and Mailbox Numbers.
Set the Dept Code As DN parameter in the RS-232 Programmable Menu to Yes.
Enter the directory number in the Department Code parameter of the mailbox.
Verify that the configuration is correct.
Assign message waiting type 7 (programmable interface) through the first or second message waiting type prompt in mailboxes that are to receive message waiting indicator requests. See Assigning Message Waiting Indicators to a Mailbox.
Test the RS-232 Message Waiting Indicators Interface application.
