DBY41001/1 Ericsson Ericsson BusinessPhone Phone Accessory

The Ericsson DBY41001/1 is an option unit designed for use with the DBC 20X series of digital business telephones. This expansion module adds functionality to the base telephone unit, enabling additional features or connectivity options within the Ericsson BusinessPhone or MD110 telephony environment.

The DBY41001/1 option unit integrates with DBC 200 series digital telephones, which were widely deployed in enterprise PBX systems. These option units typically provide add-on capabilities such as additional line keys, display enhancements, or connectivity features to extend the base handset functionality.

This is a legacy product from the Ericsson/Aastra telephony range, which has since transitioned through Mitel ownership. It remains relevant for organisations maintaining existing BusinessPhone or MD110 infrastructure where DBC 20X handsets are still in active service.
