3EH73092AB ALCATEL Alcatel-Lucent OmniPCX PBX Expansion Card

The Alcatel 3EH73092AB is an SLI16-2 analog extension card designed to provide connectivity for analog telephone devices within Alcatel-Lucent OmniPCX Office and Enterprise telephone systems. This card supports 16 analog extension ports, enabling connection of standard analog handsets, fax machines, and other analog endpoints to the digital PBX infrastructure.

The SLI16-2 card is deployed in business environments where a mix of digital and analog telephony is required. It allows organisations to integrate legacy analog devices into modern unified communications platforms, making it particularly useful during phased migration projects or in environments where analog connectivity remains essential for specific applications such as fax services or alarm systems.

This is a legacy product from the Alcatel-Lucent OmniPCX range, which has since transitioned under the Alcatel-Lucent Enterprise brand. While the platform continues to be supported in many existing installations, the SLI16-2 card represents mature technology suited to maintenance and expansion of established OmniPCX deployments rather than new installations.
