3EH73052ABAB 05 ALCATEL OmniPCX Office/Enterprise PBX Expansion Card

The Alcatel 3EH73052ABAB 05 is an SLI16-1 analogue subscriber line interface card designed for Alcatel-Lucent OmniPCX Office and Enterprise communication systems. This board provides 16 analogue extension ports, enabling the connection of standard analogue telephones, fax machines, and modems to the PBX platform.

The SLI16-1 card is deployed within Alcatel-Lucent unified communications environments where organisations require analogue endpoint connectivity alongside digital and IP telephony. It slots directly into the system chassis and is managed through the OmniPCX administration interface.

This is a legacy card supporting Alcatel-Lucent platforms that remain widely deployed in enterprise and SME environments. While newer IP-native solutions have succeeded this technology, the SLI16-1 remains essential for maintaining and expanding existing OmniPCX installations.
