CNS Multiplexers
Proven solution for Radio Status or System Management Monitoring.
CNS Multiplexers, Key Features, IP & non IP
The Ethernet IP interfaces of the CNS Multiplexers support Radar
Asterix, VoIP ED137 and System Monitoring. Proven ED137B & C VoIP
operation, for up to 16 Ground/Air Radios with a separate IP network for
Radio Status, SNMP or System Management Monitoring. The same CNS
Multiplexer simultaneously supports up to 8 legacy Air/Ground Radios, (4
wire Voice + E&M signalling, with or without phantom earth), permitting
easier transition from existing 25kHz to 8.33kHz Radios. For ATIS
requirements, mostly 4 wire Voice + E&M, the 1240 CNS Multiplexer
supports both current equipment and new VoIP systems.
For Data requirements there are X.21/RS422/RS485 & RS232 (V.24) interfaces,
primarily used on Navigational Aids and some Radars.
Dual power feeds to the CNS Multiplexers are provided to minimise a single
point of failure.
The CNS Multiplexers has an 18Vdc to 72Vdc input range, accommodating site
locations having either 24V or 48V DC battery systems (positive or negative
earth).
There is a generous 30dB optical light budget, maintained over the lifetime
of the CNS Multiplexers, achieved by the built in compensation correcting
sustaining the Laser's output level. 60Km distances should easily be achievable.
Extended versions offer 120Km (over single mode Fibre).
Provides transport of both Ethernet and non-Ethernet interfaces
Ethernet support for Radar Asterix, VoIP ED137 and system monitoring
Proven ED137B & C VoIP operation for multiple ground/air radios
Simultaneous transmission of multiple legacy ground/air radios (4 Wire E&M)
Dual power feeds to minimise single point of failure: 86-264Vac and/or 18-72Vdc
Serial support for nav aids and radar (X.21/RS422/RS485 & RS232)

A key strength of the CNS Multiplexers is its versatility to network/integrate all Aviation Manufacturers of:
Comms
Navigational Aids
Surveillance
Equipment/Systems to a (Digital) Control Tower
Combination of Ethernet and Non-IP interfaces provide a cost effective
solution for transitioning to new CNS IP based Systems.
The CNS Multiplexers assists the Safety Case with its proven operational track
record.
