Radio intercom systems
A new
line of products developed to support radio operators with intercommunication and centralized operation facilities, by use of advanced networking techniques
Radio Intercom System MRC-01 Radio
Intercom System MRC-01 allows ring-type centralization of up to 30 operator terminals without use of switching units.
The operator terminals can be of three different types:
User Termination.
Radio Termination dedicated to radio and/or modem systems,
public-address audio systems and/or telephone services .
Sharing Termination, used for inter-operation of the system
with other rings to increase the centralization capabilities.
Main features:
A digital-type ring designed for connection to the three types of
terminations.
Without any software configuration, it is possible to connect to the
ring up to 30 user Terminals and Radio Terminals or to keep them switched off.
It is therefore possible to increase or decrease the system’s
capabilities without any re-configuration.
Only one Sharing Terminal can be connected to one ring.
When a Sharing Termination is installed, the number of simultaneous
conversations shall be subtracted from the aforementioned 30 conversations in both rings.
The User Terminals are outfitted with digital Framers which allow
identification of the voice packets flowing in the ring, the Radio Terminations provide the digital-to-analog conversion and analog to digital conversions between the framers and the radio circuits.
To ensure fail-proof operation, the system has a redundant structure
consisting of two concentric rings: In case of failure of one ring, the data packets will be automatically re-routed to the other ring.
Digital communication techniques allow conference interconnections of
up to 6 users over two separate conference lines.
