Intercom System

Intercom System

This device is an Audio distribution system for centralization and distribution of audio band communication. Its main features are listed below:
Centralization of Operative Ring Terminations without Switching Unit support;
Centralization of up to 30 Terminations;
No Software configuration needed;
Digital sampling transformation of Communications;
Optoisolated signaling Inputs and Output s for Radio Terminal terminations are provided, for PTT control and status information reception of ON, Ready and BackPTT from Radio or Modem;
High redundancy obtained through the implementation of two concentric Rings. In case of fault of a communication line, the data packets are automatically sent on the opposite Ring;
Thanks to the digital communications it is possible to make conferences without any limitation on two separate conference lines;
Up to 200 meter length of communication cables between any two adjacent terminals;
Up to 50 meter length of power supply cable with more than 10 User Interfaces.
