Description

The M34116 is a product specifically designed for applications in PCM digital exchanges. M34116 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 elody.

The M34116 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).

The M34116 is full pin and function compatible with the M116. In addition, it has the capability to generate tone directly coded in PCM.

For the conference function, each channel is converted inside the chip from PCM law to linear law (14 bits). Then M34116 is added to its conference, and the sample of the previous frame is subtracted from the conference.

In this way a new conferencesum signal is generated. The channel output signal M34116 will contain the information of all the other channels in its conference except its own.

After the PCM encoding, the data of M34116 is serialized by the M34116 in the same sequence as the PCM input frame, with one frame (plus one channel) delay and will be reallocated by the DSM (M3488) at the final channel and bus position.

A programmable attenuation or gain of M34116 can be set on each channel and for every function: conference, tone generation and transparentmode.
