ASTRO 25 Enhanced Data
ASTRO 25 Enhanced Data is optimized to handle different
message sizes and variable update rates from different
applications of the radio. Add Enhanced Data to the
Integrated Data system with a software installation to
improve data channel efficiency and enable denser network
traffic.
Dynamic System Resilience (DSR)
DSR ensures the radio system is seamlessly switched to a
backup master site dynamically in case of system failure.
DSR also provides additional indication e.g. failure
detection, fault recovery, and redundancy within the system
to address to the user in need. Mechanisms related to the
Integrated Voice and Data (IV&D) or data centric are all
supported by DSR.
CrossTalk Prevention
This feature prevents crosstalk scenarios from happening,
especially when a wideband antenna is used. This feature
allows the adjustment of the internal SSI clock rate of the
radio. This subsequently reduces the possibility of radio
frequency interfering spurs and prevents the issues of
crosstalk.
Encrypted Integrated Data (EID)
EID provides security encryption and authentication of
IV&D data bearer service communication between the radio
and the Customer Enterprise Network.
SecureNet
SecureNet allows user to perform secured communications
on an Analog or Motorola Data Communication (MDC)
channel.
Conventional Talkgroup and Radio
Scan Enhancements
A few enhancements have been made to the Conventional
Talkgroup at the system. These enhancements improve the
Scan feature operation significantly when multiple agencies
are using a single conventional radio frequency channel.
These enhancements allow users to use Selective Squelch
to operate on only the subset of talkgroups that are
relevant to the users rather than all talkgroups on the
channel. These Scan improvements have been made to
eliminate the audio holes that were present and to turn on
the busy LED when activity is present on the channel.
