The WiNRADiO Advanced Trunking Option is an optional software package
| The WiNRADiO Advanced Trunking Option is an optional software
package, a collection of trunk-tracking modules, fully integrated with
WiNRADiO WR-G305e and WR-G305i receivers.
Intended mainly to satisfy the needs of a serious radio monitoring
enthusiast as well as for less demanding professional surveillance
applications, this product continues in the fine tradition of the
original WiNRADiO Trunking Option, elevating many of its
original concepts to a higher level of functionality and performance,
and adding new types of trunking.
The WiNRADiO Advanced Trunking Option contains full support for
Motorola SmartNet, MPT1327 and EDACS.
In conjunction with the optional APCO P25 decoder, the
program will follow and decode APCO P25 digitally-coded voice traffic on
3600 baud control channels (also known as Motorola Astro
which is currently the most common trunked radio system with digitally
coded voice). Free upgrade to include APCO P25 (9600 baud) control
channel trunking is planned for introduction in 2009. |
|
| The WiNRADiO Advanced Trunking Option consists of separate decoders
for each of the major supported trunked systems, SmartNet,
MPT1327 and EDACS.
Motorola ASTRO is based on the SmartNet data protocol
and therefore shares the SmartNet decoder for the control channel.
The selected decoder normally waits on the control channel (also
known as the system "data" channel) of a given trunking network until it
receives all the necessary information allowing it to tune to the
traffic ("voice") channel, by decoding it from the control channel data
stream. When this happens, the decoder "tracks" the voice channel,
tuning the receiver automatically from one frequency to another, to
ensure that the conversation is uninterrupted. When a voice channel call
terminates, the decoder then retunes the receiver back to the control
channel frequency to repeat the process. The user can select which voice
channel to track, from a displayed list of currently active channels.

| Similar control panels to the one shown above also exist for the other
trunking modes. Differences between the panels reflect the different
trunking methods and information parameters associated with these systems.
The SmartNet control panel can accommodate both analog and APCO P25 coded
voice channels (assuming that the optional APCO P25 decoder is
installed). |
The WiNRADiO Advanced Trunking Option also contains a system information
database which remembers system parameters of all previously trunked
networks, even if trunked for only a few seconds. A trunking network can
then be immediately recognized by its transmitted ID, and all relevant
system parameters can be immediately set for instant tracking action. |

|
| The WiNRADiO Advanced Trunking Option also contains a special feature
that makes it possible to observe "raw" messages decoded from the control
channel signal. This is intended for in-depth analysis, research or
troubleshooting of a trunking system. The control channel messages are
displayed for all supported trunking systems. |
For different trunking systems, the messages will be different; for
example for SmartNet the messages are displayed as numbers resulting from
basic splitting of the received data stream, while for MPT1327, the messages
are displayed in a binary form and/or human readable text, with annotations
and descriptions derived from the MPT1327 specification: |
