Product Summary

The M34063A is a PCM conference call and tone generation circuit specifically designed for applications in PCM digital exchanges. It is able to handle up to 64 channels in any conferences combination from 1 to 29 conferences in parallel and to generate seven different tones and one melody. The M34063A in a conference must previously be allocated through the Digital Switching Matrix (M3488) in a single serial wire at M34116 PCM input (IN PCM pin).
