The Ericsson DBY409 01/01001 is a key panel designed for use with Ericsson MD110 business communication systems. This hardware component provides additional programmable keys and control functions for operator or attendant positions, enabling efficient call handling and system management from a dedicated console interface.
The DBY409 key panel is typically deployed alongside operator workstations in MD110 PBX installations, allowing reception staff or switchboard operators to manage incoming calls, transfer functions, and system features through dedicated physical buttons. It forms part of the operator console configuration within enterprise telephony environments.
As the Ericsson MD110 platform has been superseded by more modern communication systems, this key panel is considered legacy equipment. It remains relevant for organisations maintaining existing MD110 installations or requiring spare components to support operational continuity of their established telephony infrastructure.
