Applications

The AT&T Lucent Avaya PC/PBX platform was widely deployed in mid-market and enterprise business environments from the late 1980s through the early 2000s as a scalable, computer-based telephone system alternative to traditional hardware PBX installations. ISA-16 cards like this one provided modular expansion capabilities, allowing system integrators and telephone departments to add additional lines, trunk connections, or specialized telephony features to a PC-based installation. This card dates from the era when ISA was the dominant expansion bus in business computing, before being superseded by PCI and modern networked VoIP systems. The PC/PBX platform is now considered legacy technology, but these cards remain sought after by businesses maintaining older telephone systems, archivists, and collectors of vintage telecommunications equipment.
