Product Summary
The M34116C1 is a PCM conference call and tone generation circuit. It is a product specifically designed for applications in PCM digital exchanges. The M34116C1 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 M34116C1 is full pin and function compatible with the M116. In addition, it has the capability to generate tone directly coded in PCM.
