3EH73052ADAB ALCATEL Alcatel-Lucent OmniPCX PBX Expansion Card

The Alcatel 3EH73052ADAB is an SLI 4-1 analogue interfaces expansion card designed for Alcatel-Lucent OmniPCX telephone systems. This card provides four analogue trunk line interfaces, enabling connectivity between the PBX and traditional PSTN analogue lines for inbound and outbound call handling.

The SLI 4-1 card is intended for deployment within OmniPCX Office and OmniPCX Enterprise communication platforms, allowing businesses to maintain analogue trunk connectivity alongside digital and IP-based telephony infrastructure. It is typically installed in available expansion slots within the OmniPCX main unit or expansion chassis.

As part of the Alcatel-Lucent OmniPCX range, this card supports legacy telephony environments where analogue trunk lines remain in active use. The OmniPCX platform, while mature, continues to be deployed in many enterprise and SMB environments across Europe and beyond.
