The W-1000-EWP has an aluminum faceplate with black textured powder paint and call progress LED. It is designed to interface directly with an unused analog telephone line input of phone system. One or two W-1000-EWP doorboxes can also share an existing phone line when used with a C-1000B doorbox controller.

When the "Call" button is pressed, the W-1000-EWP generates a standard or custom ring cadence of an adjustable number of rings. For noisy environments, the W-1000-EWP's new louder speaker output and "Push-to-Talk" feature can be used.
