The PRS‑CSR is a call station with the same functionality as the basic call station LBB 4430/00 but it uses CAT-5 cable for its connection to the Praesideo network. It connects one-to-one to the call station interface PRS‑CSI which is part of the Praesideo optical network. The CAT-5 cable carrying digital audio and control data can 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. The PRS-CSR can be extended with up to 16 keypads (LBB 4432/00 or LBB 4434/00) each with eight programmable keys.
