DBY419 01/02001 Ericsson Ericsson BusinessPhone PBX Module

The Ericsson DBY419 01/02001 is a key panel module designed for use with Ericsson telecommunications systems. This hardware component provides physical button interfaces for user interaction with telephony equipment, enabling direct access to system functions and feature keys.

Key panels of this type are typically deployed as part of Ericsson business communication systems, allowing operators or end users to access programmed functions, speed dials, line appearances, or system controls through dedicated physical keys. They serve as an extension interface for digital telephone sets or operator consoles.

This is a legacy Ericsson component from their business telephony portfolio. As Ericsson has transitioned its enterprise communications business, parts such as the DBY419 01/02001 are no longer in active production, though they remain essential for maintaining existing installations.
