This step is included simply to allow you to confirm creation of the Access Device. There are no parameters to configure.
If you are adding an Access Device to a third-party Trunk / Access Gateway, and there is already an unused TDM Port configured on the gateway that matches the port name of the new device, the task prompts you to confirm removing the configuration of this port in order to configure the Access Device. Check that the specified port is configured for access rather than for trunking before you confirm the action. Alternatively, you can cancel the task or return to the previous step in order to choose a different port. (If there is a matching TDM Port but it is in use, you will not be able to confirm the action; you must specify a different port name or cancel the task.)
