The Avaya PBX driver communicates with the PBX and carries out work orders by logging in just as a PBX administrator would. The driver uses information from the Identity Vault as well as customizable settings and policies to configure the extension correctly. After configuration is completed, the driver publishes the new phone number to the Identity Vault, and the phone can be delivered and physically installed.
The driver can be used in conjunction with other systems such as a human resources application or work order database to provide additional functionality.
The following diagram shows some of the systems you might have in your environment, and shows that you can connect the PBX to the Identity Vault by using the Avaya PBX driver.

The terminal shown in the diagram demonstrates that you can still access the PBX and make changes manually, if necessary. However, with the driver in place, you shouldn't need to make changes directly in the PBX very often. The purpose of the driver is to allow you to use work orders to control changes in the PBX, so you don't need to make them manually. Work orders can be triggered by events elsewhere in your environment, depending on what other systems you have connected by using Identity Manager.
