Park Air Systems T6 multimode digital
radios (PAE T6 MDR) offer a versatile
range of software programmable radios
that fulfi l today's analogue needs
and the growing demand for digital
communications within the aerospace
environment. Designed for long
maintenance free service, T6 radios are
the optimum choice for professional
ATC provision.
Capable of containing four different
software defi ned air interface waveforms
the B6550 Transceiver has power output
adjustable from 5 to 50W and the
receiver utilises advanced DSP algorithms
to maximise dynamic range and fi delity
for optimum performance in the
congested RF environments commonly
experienced in ATC installations.
Two variants are available covering the
118-136.975 MHz ATC band and and the
extended VHF band 112-155.975 MHz,
both are designed to provide optimal
performance in existing AM 25 kHz
and 8.33 kHz analogue services and to
offer capability for VDL modes where a
suitable ground infrastructure is in place.
The transceiver supports ICAO ANNEX 10
recommendations for 2,3,4 and 5 carrier
climax (offset-carrier) operation with
25 kHz channels and 2 carrier climax
operation with 8,33 kHz channels.
A comprehensive set of radio interfaces
provide for integration into various
alternative digital and analogue ground
infrastructure architectures commonly
deployed in ATM systems. An E1
interface supports connection to PAS
E1-RIC routers providing 29 channels of
audio and RCMS data over a single E1
line. An IP interface supports SNMP and
RCMS data for control applications and
also the latest VoIP protocols defi ned by
EUROCAE. In addition 600 ohm 4-wire
E&M analogue facilities and RS422
serial ports offer multiple interface
alternatives.
Comprehensive continuous and
interruptive built-in tests (BIT) provide
confi dence of the radio's serviceability
with results viewed on the front panel
LCD and summarised by alarm indicators.
BIT results are rolled-up and transported
via E1 and serial interfaces for remote analysis via PAE MARC or similar RCMS
systems. Front panel microphone/
headset connection and integral
loudspeaker cater for local control
applications.
Power supplies may be either standard
AC mains, or a low voltage 28V DC
nominal supply. When both input
supplies are connected, the DC supply
acts as a back up that is automaticall y
connected if the mains supply fails.
