Applications

The Premier 1224 and 2460 are key system and hybrid PBX phone systems that were widely deployed in small-to-medium business environments through the 1980s and 1990s. Station expansion cards like the 660.2200 added groups of analog station ports to these systems, allowing businesses to connect additional telephones without replacing the main cabinet. These systems are still maintained in some legacy installations today, and replacement station cards are sought after by PBX technicians and system maintainers keeping existing Premier equipment in service. The STN-A designation identifies this as the first station card slot in the system's configuration sequence.
