DBY41901/01001 Ericsson Dialog 4000 Phone Accessory

The Ericsson DBY41901/01001 is a Key Panel Unit (KPU) designed for use with Dialog 4000 series digital telephones. This expansion module provides additional programmable keys, enabling users to access more lines, features, and speed-dial functions directly from their desk phone.

The KPU is intended for deployment alongside Dialog 4000 series handsets within Ericsson BusinessPhone and MD110 PBX environments. It is particularly suited to reception desks, executive assistants, and call-intensive roles where rapid access to multiple extensions and features is essential.

The Dialog 4000 series and associated accessories are legacy products, now discontinued by the manufacturer. However, they remain in active service across many enterprise installations, and refurbished units provide a cost-effective solution for maintaining and expanding existing deployments.
