Ascom Telligence Passive Bus Concentrators (PBCs) serve as the interface between the Gateway and passive modules. They provide and regulate power, communicate data, and supervise the system. These devices help ensure that Telligence keeps on working, even when there is a partial failure in the system. They also help maximize your investment in Ascom technology by supporting migrations from earlier Ascom nurse call systems. Their flexibility makes them suitable for all types and sizes of healthcare facilities.
