Configure Programmable RS-232 MWI

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:

  1. Complete an RS-232 Message Waiting Indicators Interface Worksheet.

  2. 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.

  3. Create the interface string. See Creating a Programmable RS-232 Interface String.

  4. 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.

  5. Enable or disable indicator-on requests for successive messages. See Enabling/Disabling Light-on Requests for Successive Messages.

  6. 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.

  7. Compensate for different directory number and mailbox numbers, if necessary. See Compensate for Different Directory and Mailbox Numbers.

  1. Verify that the configuration is correct.

  2. Activate the configuration.

  3. 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.

  4. Test the RS-232 Message Waiting Indicators Interface application.
