The phrase "Master Key Telephone" refers to a Key Telephone System (KTS), a multiline phone setup originally designed for small-to-medium businesses. Historically, these systems are distinguished by having "keys" (buttons) that allow users to manually select and directly interact with specific individual lines, providing visible status (e.g., busy/idle) for all connected lines across all handsets.
