Abstract

Abstract A faceplate assembly for a telecommunications terminal is of sandwich structure, having top and bottom members. A plurality of apertures through the members permit passage of pushbuttons and other activating members. Channels open at one end are associated with at least some of the apertures for the introduction of cards, having indicia relating to the associated activating member. The top surface of the top member has a non-glare finish. An opaque background color can be applied to the back surface of the top member, having clear windows aligned with the channels. Indicator areas can be provided adjacent to at least some of the apertures, for provision of lighted indication. These indicator areas can have translucent colored ink applied, on the back surface of the top member, to enhance the lighted indication.
