BOSCH PRS-CSI Call Station Interface

BOSCH PRS-CSI Call Station Interface

The PRS-CSI is a professionally designed interface between a single remote call station, PRS-CSR or a remote call station kit, PRS-CSRK and the fiber optical Praesideo network. It comes using a CAT-5 cable for the connection to the remote call station. The CAT-5 cable, which is carrying the digital audio and control data, are capable to be as long as 1 km. The length of the CAT-5 cable is not a part of the Praesideo optical network length. This considerably increases the overall possible length of the optical network, especially in cases, where the call station is placed far from the rest of the system. The call station interface is capable to get its power from the Praesideo network, and/or from a local power supply. It is fully supervised.

Functions
The interface is capable of connecting a single PRS-CSR remote call station or PRS-CSRK remote call station kit to a Praesideo system that comes along with up to 1 km of CAT-5 cable. The interface is created fully digital, capable of supporting high-quality sound along with a built-in DSP for audio processing of the remote call station. It comes capable of supporting complete supervision of itself, the call station and the connection, as well as of two control inputs. It is supporting the fail safe mode of remote call stations, allowing them of putting through emergency calls, even if the network controller fails. The unit is configured with the use of the network controller.
