Product Summary
The M34116B1 is a PCM conference call and tone generation circuit. The device is specifically designed for applications in PCM digital exchanges. The M34116B1 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 parties in a conference must previously be allocated through the Digital Switching Matrix in a single serial wire at M34116B1 PCM input (IN PCM pin). The M34116B1 is full pin and function compatible with the M116. In addition, it has the capability to generate tone directly coded in PCM.
