Praesideo Call Station Remote

The P004222N is a call station with the same functionality as the basic call station, P004241N, but it uses CAT-5 cable for its connection to the Praesideo network. It connects, one-to-one, to the call station interface, P004242N, which is part of the Praesideo optical network. The CAT-5 cable, carrying digital audio and control data, can be as long as 1km. 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 P004222N can be extended with up to 16 keypads (P004233N), each with eight programmable keys.

• Connects to call station interface via CAT-5 cable


• Up to 1 km from Praesideo optical network
