The MOSCAD is engineered into all of M's larger radio systems for the purpose of monitoring all critical pieces of the pie (RF, microwave, backbone data, GPS, tower lights, HVAC....Yada Yada Yada). It has nothing to do with MDC's. On a different note, I can say that they will be starting a pilot MDC program shortly, but it will use a cellular/PCS carrier for the wireless piece. Motorola is still behind the curve on tha data side of the fence.
