At the heart of the M4x Blade Communication System are DSP (digital signal processor)- powered “modules”.  These modules, manufactured by Raven Electronics, provide “access points” for several different types of communication equipment including radios, telephones, the public telephone network, orderwire, and even alarm and control equipment.

The M4x Blade Communication System can accommodate up to 8 such access points, and under software control, can bridge or conference them in any combination.

And that’s just the beginning of the M4x Blade Communication System’s versatility.  Potential uses of the M4x Blade Communication System include: radio interoperability, dispatch center call matrix, dispatch console, call conferencing system, or a small office telephone system.
