Map27 library

This is the Map27 library. It provides a C++ object-oriented interface for sending and receiving message to a Map27 enabled trunked radio.

Map27 (http://en.wikipedia.org/wiki/Mobile_Access_Protocol specifies an interface between a trunked mobile radio and a data terminal equipment. This library is based on "MAP27 Mobile Access Protocol for MPT 1327 equipment Version 1.5" (http://www.mpt1327-usa.org/downloads/map27.pdf) from the User Access Definition Group.

This library, along with a Map27 comnpatible trunlked radio can be used to set up voice and data calls between radios, and to monoitor the activity of the radio.

The specification defines the following ISO conforming network layers:

Map27 library has been tested on Unix (OpenSuSE 12.3) and should run on any modern linux. It has been tested against:

It has been designed to be readily portable to other architectures and OSs, including QT and Arduino (athough this has not yet been done)

Overall Architecture

The usual way to construct a complete ap27 application is to create your own subclass of Map27ApplicationLayer, then interconnect it to the other protocol layer classes like this:

* [Your subclass of Map27ApplicationLayer]
* ^ |
* | v
* ^ |
* | v
* ^ |
* | v
* ^ |
* | v
* [ subclass of Map27Port, such as Map27UnixPort ]
* ^ |
* | v
* [ RS232 connection ]
* ^ |
* | v
* [ Map27 enabled trunked radio ]
*
Logging

A simple logging facility is provided in Log.h and Log.cpp, which can be customised and overridden to suit your needs.
