ProVoice

ProVoice is MA/Com / Ericsson's implementation of IMBE Digital modulation. It is NOT APCO-25 compliant, but does use the same IMBE vocoder developed by DVSI Inc. The only difference from the APCO-25 standard is how error correction and modulation is provided to transmit the data. San Antonio TX, The State of Florida, and St Tammany Parish are using ProVoice EDACS solutions.

EDACS ProVoice systems use the MA/Com / GE EDACS Control Channel.

There is NO scanner available today that can monitor EDACS ProVoice Digital voice.
