Passive Bus Concentrators

Passive Bus Concentrators (PBCs), used with Ascom Telligence Patient Response Systems, serve as the interface between the Gateway and passive modules. The concentrator distributes power and communication to its eight passive buses and their attached modules.

 Passive Bus Concentrators provide and regulate power, communicate data, and supervise the Ascom Telligence system. These devices help ensure that an Ascom Telligence nurse call solution 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. 


For new system scalability and cost-effective migration from legacy Ascom nurse call solutions
