Ericsson ZAT505401/01 TAU 2680 terminal adapter for MD110 PBX systems.

The Ericsson ZAT505401/01 is a TAU 2680 Terminal Adapter Unit designed for integration with Ericsson MD110 and BusinessPhone PBX systems. This device provides connectivity for analogue terminal equipment, enabling legacy devices to interface with digital telephony infrastructure.

The TAU 2680 is typically deployed in enterprise environments where analogue endpoints such as fax machines, modems, or traditional analogue telephones need to connect to an Ericsson digital switching platform. The unit handles the necessary conversion between analogue signals and the digital protocols used by the PBX.

This is a legacy product from Ericsson’s enterprise telephony portfolio, which has since transitioned through various ownership changes. While discontinued, the TAU 2680 remains in active service across many installed MD110 systems, and replacement units are sought for maintenance and expansion purposes.
