V3R-FX-INTERCOM for Clear-Com/RTS was developed to enable direct interfacing between the Optocore open transmission and Clear-Com/RTS Matrix platforms allowing for a flexible audio based intercom transport solution. It is now possible to take advantage of all Optocore system features and benefits when communicating through an Eclipse Matrix intercom system. Based on the well known V3R-FX series architecture, with 1U height, the device is equipped with standard RJ45 interfaces, making cabling simple and cost-efficient. V3R-FX-INTERCOM offers not only intercom interfacing, but can be used also as analog audio Line-In and Line-Out device. 

Optocore's intercom device is seamlessly integrated into the OPTOCORE® OPTICAL DIGITAL NETWORK SYSTEM. Intercom messages and control data from Clear-Com/RTS user panel or matrix are sent transparently through the optical network. Each single intercom channel can be routed to every device in the network by the OPTOCORE CONTROL software.
