3BA23171ABBE 02 ALCATEL OmniPCX Enterprise PBX Expansion Card

The Alcatel 3BA23171ABBE 02 is an NDDI2-2 interface card providing two digital trunk ports with Loop Start (LS) and Ground Start (GS) signalling support. This card enables connection to public switched telephone network (PSTN) services via analogue trunk lines, handling both inbound and outbound call routing.

Designed for deployment within Alcatel OmniPCX Enterprise communication servers, the NDDI2-2 card serves as a critical interface between the PBX system and external telephone network infrastructure. The dual-port configuration allows for connection of two analogue trunk lines, supporting legacy telephony connectivity requirements.

This is a legacy product from the Alcatel-Lucent OmniPCX platform, which remains in service across many enterprise installations. The LS/GS signalling capability ensures compatibility with various central office configurations and PSTN service types commonly encountered in established telephony environments.
