The Ericsson DBY40901/02001 is a key panel expansion module designed for use with the Dialog 3000 series digital telephones. This add-on unit provides additional programmable keys, extending the functionality of the base telephone by offering quick access to frequently dialled numbers, speed dials, and feature shortcuts.
The key panel integrates with Ericsson BusinessPhone and MD110 PBX systems, allowing users to manage multiple lines and functions efficiently. It is particularly suited to receptionists, executive assistants, and call-handling roles where rapid access to extensions and external lines is essential.
The Dialog 3000 series and associated accessories are legacy products, with the platform now superseded by newer IP-based solutions. However, these key panels remain in demand for organisations maintaining existing Ericsson/Aastra PBX infrastructure, where they continue to provide reliable service.
