Audio Levels for the MLC 8000 Link Converter for Analog or Mixed Mode

Input Level Differential is important for two reasons: voting and system deviations. For voting, the MLC 8000 Input Level Differential parameter requires a calculation using the value in the Status Tone/ALMT Level Below Peak Audio field for the GTR 8000. The setting depends on whether the channel is analog only or mixed mode.

If the Rx Wireline level is set to -10 dBm in the GTR 8000, the general formula is:

Input Level Differential = Status Tone/ALMT Level Below Peak Audio + 4.4, or
Status Tone/ALMT Level Below Peak Audio = Input Level Differential - 4.4

For example, if Input Level Differential (dB) is 0, then Status Tone/ALMT Level Below Peak Audio is -4.4. Peak audio is considered 100% deviation.
