The CMX188 offers the combination of an embedded low bit-rate vocoder, audio-band modem and digital voice.

The migration from analog to digital two-way radio is proving to be slow, with the majority of two-way radios in the field still being analog. The slow transition is associated with the complexity and implementation cost of modern digital radio systems together with the need to provide backward compatible operating modes, to enable communication with the wealth of legacy analog systems already deployed today. The CMX188 ACE Processor solves these problems, bringing new life to analog PMR radios by working alongside the radio’s existing analog baseband processing and providing the digital advantage.

The plug and play solution provided by the CMX188 ACE Processor provides a new approach by enabling digital voice features and functionality not normally found on analog two-way radio. These include: secure digital voice encryption, digital voice storage/retrieval including step back feature, instant voice capture to eliminate PTT clipping, auto-adaptive VOX and packet data.

Built into the CMX188 is CML’s proven and reliable RALCWI (Robust Advanced Low Complexity Waveform Interpolation) vocoder providing near toll quality speech at a low bit-rate. Noise gating is included in the Vocoder function, in both transmit and receive operations to minimise the effects of background noise and improve the overall voice quality.

The CMX188 is a plug-and-play device built on CML’s FirmASIC technology and is available in small 48-pin VQFN and LQFP packages.
